Dickinson College ASHRAE Level II Energy Audit 1 Executive Summary Dickinson College, founded in 1773, is a highly selective, private residential liberal-arts college known for its innovative curriculum. Its mission is to offer students a useful education in the arts and sciences that will prepare them for lives as engaged citizens and leaders. The 180 acre campus of Dickinson College is located in the heart of Carlisle, PA In September 2009, Dickinson College (DC) announced a bold new Climate Change Action Plan with a goal of reducing greenhouse gas emissions by twenty-five percent (25%) versus 2008 levels by the year 2020. By complementing that on-site reduction with the purchase of carbon offsets and grid power from renewable sources, total net carbon neutrality will be achieved. Climate Action Plan In June 2012, Dickinson College retained the services of THE STONE HOUSE GROUP (SHG) to perform an ASHRAE Level II Energy Audit in support of the Climate Action Plan. The Audit was to cover five (5) buildings on campus: Spahr Library Waidner Library Rector Science Complex (James Hall) Adams Hall Holland Union Building (HUB). This report describes the findings and recommendations developed over the course of this energy audit. During the course of multiple on-site inspections, as well as a review of the drawings and automated control system for the buildings, over 100 potential energy conservation measures (ECMs) were identified. We have compiled these measures, with input from Dickinson College operations and maintenance personnel, into an energy capital investment plan (ECIP) which can be found in Section 3 of this report. This ECIP shows the estimated capital costs and savings (consumption, cost and emissions) associated with each proposed measure. The Stone House Group Page 3
Dickinson College ASHRAE Level II Energy Audit In total, we estimate these measures will: Cost approximately $1.2 million to implement. Save about $330,000 on energy bills each year (at current utility rates). Pay for themselves in 3.5 years. Prevent the release of the equivalent of 1,900 metric tons of.

Dickinson College ASHRAE Level II Energy Audit 2 Energy Profile: Consumption, Cost, and Carbon at Dickinson College 2.1 Energy Consumption THE STONE HOUSE GROUP S energy study of Dickinson College revealed that the College is a relative champion of energy efficiency. On a per square foot basis, the College outperforms almost all peer institutions we have data for. Interviews with the facilities staff confirmed that the College has had a strong energy management focus for many years and has implemented many high ROI (low hanging fruit) projects on campus. They also operate their buildings very aggressively and try to closely match the HVAC systems operating hours to the intended use of the building. The College is aggressive during low use periods of campus (holiday breaks) and has a formal Curtailment Program that has been effectively used for many years to reduce temperatures and limit energy use in buildings during these times. Figure 1 shows Dickinson s energy use, during fiscal years 2010, 2011, and 2012. Data from 21 other similar institutions was used for comparison, and Dickinson College beats almost all of them in terms of energy use per gross square feet which is a great barometer of energy and environmental stewardship. 250.0 200.0 MBTU / sq. ft 150.0 100.0 Average 114 50.0 0.0 Figure 1: Energy use in MBtu per square foot at Dickinson (shown in red) Our analysis showed, however, that on a per student basis, the College is closer to the average of 60,000 MBtu / student. Please note that MBtu denotes Btu x10 3 (Btu is a unit of energy). Year MBtu / Student Survey Average 60,000 DC 2010 53,900 DC 2011 56,600 DC 2012 53,500 The Stone House Group Page 5
Dickinson College ASHRAE Level II Energy Audit As indicated in Figure 2, the most-consumed type of energy is electricity (49% of total). Natural gas makes up a nearly equal component; less than two percent (2%) of the College s total consumption is in the form of fuel oil and on-site renewable resources. Fuel Oil, 1,683 Vegetable Oil, 1,200 Solar, 323 Natural Gas, 61,909 Electric, 62,524 Figure 2: Total Energy Use at Dickinson College, FY 2012 (MMBtu) Please note that because the numbers are larger, we have shifted to MMBtu (= Btu x10 6 ) 2.2 Energy Cost Electricity is not only the most-used; it is also the most expensive energy at Dickinson College (see Fig. 3). Electricity coming in through the main electric meter gets a better rate than the various independent meters spread around campus; but even the main meter still costs 30% more than fuel oil and three times as much as natural gas. ( $ / MMBTU ) $50.00 $45.00 $40.00 $35.00 $30.00 $25.00 $20.00 $15.00 $10.00 $5.00 $0.00 $30.33 $29.11 Main Electric $43.49 $40.40 $9.33 $9.19 $22.76 $23.33 $18.85 $20.02 Independent Natural Gas Fuel Oil Campus Electric Average FY 11 FY 12 Figure 3: Fiscal Year 2011 and 2012 Dickinson College Energy Unit Costs The Stone House Group Page 6
Dickinson College ASHRAE Level II Energy Audit The total energy cost, by source, is as follows (solar and vegetable oil have no associated yearly cost): Fuel Oil $39,276 2% Natural Gas $568,797 22% Electric $1,946,833 76% Figure 4: Total Energy Expenditure, Fiscal Year 2012 Unfortunately, sub-meter data was not available to provide exact numbers for every month and every fuel in the audited buildings. However, using some actual readings and some average data, we can estimate the yearly energy costs for each of the buildings. Building Estimated Energy $ per year Libraries $160,000 Rector $365,000 Adams $43,000* HUB $220,000 *From actual billing data. Average of FY10, 11, 12. 2.3 Carbon We know that the College s impact on the environment is important to Dickinson, as expressed in your 2009 Climate Change Action Plan. Figure 5 summarizes the total carbon dioxide equivalent emissions ( e) produced by campus consumption of natural gas, fuel oil, and grid electricity. These would be considered Scope I and Scope II emissions as defined in the College s Climate Action Plan. The carbon dioxide equivalent calculation takes into account that certain gases which are emitted during power production have a more potent contribution to the greenhouse effect than. For example, because methane (CH 4 ) is twenty-five times (25x) as potent a greenhouse gas as, one metric ton (MT) of emitted methane would appear in this analysis as 25 metric tons of e. The Stone House Group Page 7
Dickinson College ASHRAE Level II Energy Audit Looking over the past three years, emissions from on campus energy consumption at Dickinson College have not changed dramatically, although close scrutiny reveals a slight increase over time from 2010 to 2012. 16,000 14,000 12,000 10,000 8,000 6,000 4,000 2,000 0 FY10 FY11 FY12 CO2e (MT) Figure 5: Equivalent Emissions from On-campus Electricity, Gas, and Oil Use (Metric Tons).

Dickinson College ASHRAE Level II Energy Audit 3 Energy Conservation Measures (ECMs) 3.1 Energy Capital Investment Plan (ECIP) The ECIP incorporates all the energy conservation measures we have identified for consideration by Dickinson College. There are over 100 ECM s identified, which are detailed in the Appendices. Below is a summary of all the ECM s for the five buildings surveyed as part of this energy audit: Gas Reduction (MMBtu) Electric Reduction (MMBtu) Reduction (metric tons) Cost to Implement Annual $ Savings Payback Years Return on Investment 10,630 7,649 1,927 $1,156,789 $330,881 3.5 29% Comparing these estimated reductions with the consumption numbers from the 2011-12 fiscal year, we find that they represent a significant decrease in energy use. In terms of emissions, they could account for almost half of Dickinson s target reduction. Electricity Natural Gas e Dollars 2012 Use (MMBtu) 62,524 61,909 14,519 $2,554,906 Reduction (MMBtu) 7,649 10,630 1,927 $330,881 % Savings 12.2% 17.2% 13.3% 12.9% 3.2 Measures Considered but Not Recommended There were a number of potential measures which we noted during the course of the audit but which we ultimately are unable to recommend putting into action at this time. Reasons for being cut from the list ranged from lack of economic appeal to user-unfriendliness to the College operations staff just thinking something wasn t feasible. Here we present a sample of these projects: ECM-1067, Adams Room AC Control: We initially thought it would be a good idea to outfit the student rooms in Adams with occupancy controlled air conditioners. However, due to the warm-up time required before getting cold, and potential component failure, we thought it might cause too much user dissatisfaction. ECM-1076, Adams Drain Waste Heat Recovery: We identified the shower and washing machine drainpipes as a source of heat currently wasted (from hot water) which could be captured and reused; but this would be better done in the future when the work could coincide with other renovations to save costs. ECM-1108, HUB Water-cooled Condensers: The walk-in cooler / freezers in the HUB use air-cooled condensers now, but water-cooled units could help save energy. However, we The Stone House Group Page 9
Dickinson College ASHRAE Level II Energy Audit met with the College operations staff and this was one of the ECMs they had some reason(s) for not wanting to implement. ECM-1003, Waidner VAVs: The VAVs throughout are nearing the end of their useful life. Replace VAVs, providing DDC control with occupancy sensors (enclosed locations) and sensors (coverage for all locations). ECM-1018, Spahr Aerators for Sinks: Install aerators to reduce flow at the lavatories to reduce hot water heating energy and water consumption (currently 2.2 gpm). Also consider retrofit kits to reduce flow at the water closets (currently 1.6 gpf). ECM-1091, HUB E-cube sensors: Install ecube temperature sensors at the remaining coolers. These sensors simulate the temperature of frozen food instead of merely reading air temperature. ECM-1047, Rector Solar HW Heating: Investigate opportunities for solar hot water heating. Note that the existing hot water heating is in the north bar penthouse below the flat roof. ECM-1035, Rector Heat Exchanger Cleaning: Implement a process for heat exchanger cleaning. 3.3 Widely-Applicable ECMs During our time on campus, we found that the College operations staff already keeps very tight control over many of the energy-consuming systems and aggressively pursues opportunities to reduce energy consumption. We hope that our observations and recommendations can take their efforts to the next level of effectiveness. THE STONE HOUSE GROUP engineers made several visits to inspect the facilities in question. Most of the energy saving recommendations we have developed are specific to certain systems in certain buildings, and these are discussed in subsequent sections of this report. However, we also identified several measures that were common to multiple locations, and are probably applicable to other buildings on campus that were not audited. Many of these are listed in the Operations and Maintenance (O&M) Opportunities sections below. As a note of explanation, THE STONE HOUSE GROUP identifies six categories of ECMs (following six subsystems of energy management) based on our approach to providing a comprehensive energy focus for our clients. These are: Data The collection and management of energy use information. Procurement The obtaining of energy from an outside supplier or utility company. Generation The production of energy on site (renewable or not). Distribution The distribution of energy through campus or within a building. End Use The interaction between energy and the people using it. The Stone House Group Page 10
Dickinson College ASHRAE Level II Energy Audit Community Involvement The cultivation in managers, operators, and users, of an attitude that energy is not a limitless gift but a precious resource which must be conserved and managed wisely. The Stone House Group Page 11
Dickinson College ASHRAE Level II Energy Audit 4 Waidner-Spahr Library 4.1 Summary of Systems Spahr Library was built in 1967 and uses much of its original system equipment to this day; some of it is no longer used but remains in place. Renovations including the addition of Waidner in 1997 brought new equipment to that side of the building. Heating / Cooling: Three Air handling units (AHUs) in Spahr provide constant volume airflow and heating/cooling with a two pipe system that switches between modes, alternately using hot water or chilled water depending on the season. Two Waidner AHUs, located in the penthouse mechanical room, are equipped with variable frequency drives (VFDs) to allow variable airflow and a four pipe system capable of simultaneous heating and cooling. A series of hot water zone pumps located in the penthouse provide heating to various zones and systems as required. The collections area in the lower level is served by dedicated systems to maintain precise temperature and humidity limits. Chilled water is piped to the libraries directly from the College central plant. Steam from the central plant is run through a heat exchanger in HUB which provides hot water to Spahr and Waidner. Spahr distributes air through a pressurized ceiling plenum with slots in the ceiling panels that provide conditioned air to the space. Lighting: Large six-lamp fixtures covered with lenses provide over 90% of the lighting for Spahr. These appear to be original to the building. Selected stacks have supplementary lighting suspended in order to illuminate the aisles. Local lighting control is limited switches operate large numbers of lights. Domestic Hot Water: A mix of electric and gas hot water heaters serve different areas of the library. Temperatures are kept to a minimum, and some units were off at the time of inspection. Perimeter Radiation: Spahr Library uses electric perimeter baseboard radiation, though operation is limited to reduce energy costs. The Waidner Library has hot water perimeter radiation installed around the perimeter of the building. Terminal Units: Waidner is equipped with variable air volume boxes with hot water reheat and pneumatic controls. Spahr has a number of electric reheat coils installed above the plenum ceiling but these systems are not active and are rarely if ever used for heating the building. The Stone House Group Page 12

The overall numbers for the Library total as follows: Gas Savings 872 MMBtu Electric Savings 1,862 MMBtu e Reduction 378 MT Implement Cost Annual Savings Payback $397,430 $62,610 6.3 years ROI 16% 4.3 O&M Problems / Opportunities One of the glycol pumps appears susceptible to cavitation (suction pressure indicates zero psig upstream of several fittings; glycol feedwater is valved shut). This opportunity also exists at the zone pumps due to circuit setter placement. Damper actuators (e.g. associated with EF-3 at penetration to mechanical room; to exterior in Spahr penthouse) do not function. Some points (i.e. enthalpy for economizer control, a Waidner AHU mixed air temperature (MAT), exterior level) per design are not displayed at the drawings. There does not appear to be any fresh air to the collections area. Increase the frequency of filter replacement at the Waidner AHUs. Provide an outlet timer (with battery backup) to reduce unit cycling and unoccupied use of the domestic hot water heater (DHWH). (Waidner electric DHWHs located at Collections and near penthouse; penthouse unit off at disconnect). The building management system (BMS used interchangeably with building automation system BAS) for Spahr AHU-3 indicated the outdoor air (OA) damper position at 100% OA while the discharge air temperature (DAT) was over 20 F above the outdoor air temperature (OAT) (inspection during winter month). Please review for proper operation. The libraries are candidates to have a separate outdoor air temperature lockout on their HVAC systems. Even if the central plant has temperature setpoints and does not usually run 24 hours a day, putting a separate lockout on each building will reduce pump power expenditure and radiation losses. We recommend installing submeters to record and track all energy use in the libraries. This information can be used to identify future performance improvement possibilities as well as confirm the impact of implemented changes. Allowing static pressure reset on Waidner AHU-1 and AHU-2 will ease unnecessary stress on downstream components and reduce the amount of power consumed by the fans. The Stone House Group Page 13
Dickinson College ASHRAE Level II Energy Audit Upgrading the T8 fluorescent lighting to spectrally-enhanced lamps will allow lighting power levels to be reduced without affecting lighting levels or interfering with patrons. The current lamps seem to have a correlated color temperature (CCT) of about 3000; a change to 5000 should be investigated. We recommend eliminating constant volume airflow and replacing those units with variable flow (VAV) equipment. There may be some room for unoccupied setback in the Collections area. Methods of reducing solar heat gain through windows should be evaluated this will reduce the cooling load during sunny months. Low emissivity films or coatings may not be a good choice considering the construction of the windows, but interior shades or blinds would be effective and could be chosen to complement library décor. A program of equipment sensor calibration should be developed to ensure that readings at the front end of the building management system are accurate. A program of cleaning and inspection of strainers in the heating systems should also be implemented. The Stone House Group Page 14
Dickinson College ASHRAE Level II Energy Audit 5 Rector Science Center James Hall 5.1 Summary of Systems Air: James Hall is served by five (5) large air handling units located in the North and South mechanical penthouses. Variable air volume (VAV) boxes and exhaust air dampers throughout the building provide local temperature control as well as laboratory ventilation and pressurization requirements. Heating: The central steam plant provides low pressure steam to the building for heat during the winter months and heating hot water via two parallel heat exchangers located in the basement mechanical room. The majority of the classrooms, labs and offices are heated with VAV boxes with hot water reheats, hot water radiant panels or fan coil units. Summer reheat for the lab spaces was provided by the hot water boilers in old James Hall but due to flow issues was not effective. The Rector Addition project, currently under construction, is installing two hot water condensing boilers to provide reheat capability during the summer months. Cooling: Chilled water is provided from the central chiller plant to the building during the summer months and a chiller on the rooftop of the Tome science building is available for winter/shoulder season operation if needed. Lighting: Lighting throughout meets current efficiency standards, predominantly using compact and linear fluorescent fixtures. Daylight controls are available in the labs, and may be utilized to a greater extent. Domestic Hot Water: A gas-fired water heater located in the mechanical penthouse maintains the domestic hot water loop at temperature. 5.2 Rector ECIP The Rector Science Center ECIP includes the following ECMs: 1034 1036 1042 1044 1045 1048 1052 1054 1055 1056 1058 1059 1117 1118 1133 Please see Appendix B for details. The overall numbers for Rector total as follows. Rector consumes the most energy out of the buildings covered in the audit, so the savings to be realized here are the greatest: The Stone House Group Page 15
Dickinson College ASHRAE Level II Energy Audit Gas Savings 6,004 MMBtu Electric Savings 4,548 MMBtu e Reduction 1,129 MT Implement Cost Annual Savings Payback $392,600 $194,703 2.0 years ROI 50% 5.3 O&M Problems / Opportunities Shavings were observed under the HWP-2 coupling (also HWP-1 to a lesser extent). The exhaust section of AHU-V-1 does not consistently drain properly (potential piping pitch/trap review). Water has also been observed dripping onto the floor at the supply side at times. Variable frequency drive (VFD) fans of disconnected units remain on (North Bar AHU-1, 2 alternate). Include VFD filters during filter review. The steam flow shown at the hot water graphic indicated negative while it was serving the heat exchangers. SB-AHU-1 did not maintain the discharge air temperature (DAT) setpoint (or requires sensor calibration). The heating valve maintained a leaving coil temp of 60 F, although this translated to a supply air temperature of 52, well below setpoint. Note that checks at a few VAVs (with valves closed) indicate that the supply air (SA) may be greater than 52. At SB-AHU-2, heating leaving temp is 60.11, DAT is 52.21 (similar to SB-AHU-1 issue). DHWH barometric damper not balanced. The north bar is unable to maintain the programmed supply or exhaust static with one unit in operation. Hoods at both building wings enter alarm during high demand, indicating that static pressure setpoints should also be reviewed. Per a check of NB-AHU-1, openings were observed (for conduit) across the fan section, allowing continuous bypass around the fan. Ensure that all internal openings are effectively sealed. Per the BMS, the preheat temperature at NB-AHU-1 was 129.66 F while the unit was not in operation. Per a visual inspection, the sensor/coil was cold. Per the BMS, NB-AHU-1 indicated a flow of 2,336 cfm (cubic feet per minute) while the unit was not in operation. We recommend that leakage is examined and airflow measuring stations are calibrated. Lab 2125 indicates a GEX flow of 952 cfm with the damper fully closed. There may be an opportunity to reduce the unit heater setpoints at the penthouse, notably under the petal roof areas. The BMS indicates that point RSC.2008.3:DAY.NGT has failed (second floor south). The energy wheel controller at SB-AHU-1 is in alarm. The reset knob is broken. Exterior insulation is incomplete at a portion of the wall under the North Bar petal roof, and there appears to be a small opening to the exterior. Room 1118 indicates a failed point, and displays a DAT substantially higher than the AHU discharge with the hot water valve commanded fully closed. The Stone House Group Page 16
Dickinson College ASHRAE Level II Energy Audit RSC.STAIR1.6 indicates a failed sensor. Per visual inspection, the display is not shown at one of the two sensors at the lower level lobby area. Room 1109 indicates a discharge air temperature of 93 F while the hot water valve command remains fully closed. The space was found to be well above setpoint. Room 1107 indicates a failed point at the BMS. Fume hood monitor (RSC.118.FHM) indicates face velocity but not airflow (cfm) or sash position (both are required to calculate face velocity). There is some question whether this hood is drawing excessive air, potentially if the sash width is not input correctly. The vivarium maintains a low space humidity with the humidifier commanded 100% open. It is possible that cycling of the steam plant reduces humidity further at night. Building design appears to require continuous steam for building reheats (after Hx) and AHU steam. Exhaust fan EF06 was observed commanded on with no current draw or status. One of the exhaust VAVs in room 2117 indicates an exhaust airflow of zero although the setpoint is 900 cfm. Another exhaust VAV serving this space exhausts only 132 cfm (setpoint remains 900 cfm). Associated snorkels appear to be taped shut. The supply air VAV in 1206 provides 48 cfm (less than setpoint) with the damper commanded fully open. This also applies to the exhaust air VAV in 1202 The supply air VAV in 1202 maintains a high discharge air temperature (81 F) with the valve commanded shut. This also applies to a supply VAV in 1121 and 2112. Increase the frequency of AHU filter replacement for outside air applications. At the time of the site visit, filter loading (i.e. dirt and debris) was excessive due to outside air pulled from the adjacent construction site. Insulate the hot water air separator. Close the shot feeder valves when not in use. This will decrease hot water bypass and reduce heat loss through uninsulated piping. The graphics indicated the hot water perimeter loop with a temperature drop of 0.1 F while the pump maintained 66% with the bypass closed. Investigate sensors and review opportunities for a differential pressure reset. Install programmable thermostats (alternate DDC control) for the stair fan coil units (FCUs). Reduce temperature setpoints as applicable based on curtailment program. A program of equipment sensor calibration should be developed to ensure that readings at the front end of the building management system are accurate. A program of cleaning and inspection of strainers in the heating systems should also be implemented. We noted that it seems that only one of the heat exchangers is connected to steam. Enabling steam flow to both heat exchangers will increase the heat transfer area and allow pumps to be run at a lower speed. We recommend installing submeters to record and track all energy use in the science center. This information can be used to identify future performance improvement possibilities as well as confirm the impact of implemented changes. The Stone House Group Page 17
Dickinson College ASHRAE Level II Energy Audit 6 Adams Hall 6.1 Summary of Systems Air: Dorm rooms are provided with operable windows to allow natural ventilation to the spaces. Building exhaust fans are restricted to toilets and temperature control of unoccupied spaces. Heating: Adams Hall is not connected to the central plant two dedicated boilers provide hot water for the radiant heaters in the building, and maintain redundant capacity. The boilers are provided with dual-fuel capability to take advantage of low, interruptible gas rates. Zone pumps located in the basement currently operate based on outdoor air conditions. However, BAS control is being provided to allow scheduled setback as well as improved system monitoring. Cooling: Student rooms are equipped with local air conditioners during the warmer months. Air conditioners are owned and maintained by the College. Lighting: Lighting throughout has not been upgraded with advances in lighting technology, and with most lighting power consumed by T12 fixtures. Occupancy sensors are not utilized at dorm rooms or circulation areas, and present some opportunity for savings in addition to fixture modernization. Domestic Hot Water: Two gas-fired water heaters located in the basement mechanical room distribute hot water throughout the building. Capacity is available to maintain peak hot water flows to restroom fixtures, which present some opportunity for flow reduction. A hot water recirculation pump maintains the loop temperature during periods of low use. Adjustment is available through an existing aquastat to allow energy savings through controlled setback.

Operate boiler with increased efficiency rather than regular switchover. Adjust airflow to the mechanical room as needed to optimize boiler efficiency. Implement program for recording efficiencies and age of building appliances (student refrigerators, microwaves and air conditioners) to optimize with replacement schedule and payback opportunities. Install a thermal mixing valve to reduce water distribution temperature (serves lavatories and washing machines). There may be an opportunity to reduce tank temperature. Note that some standards recommend tank temperatures higher than distributions temperatures to prevent Legionella. Install thermostatic valves in the dorm rooms to cut down on excessive runtime of heating. A review of piping configuration is required to ensure this is viable. Clean radiators (conditions vary) and exhaust ductwork. Cap openings to the exterior at the 4th floor fan room. Dual-flush valves can be retrofitted onto existing water closets to provide a low-flow option. The Stone House Group Page 19
Dickinson College ASHRAE Level II Energy Audit 7 Holland Union Building (HUB) 7.1 Summary of Systems Air: With a large variety of room types and usage schedules, air handling in HUB is a mixand-match affair with 21 different units serving various areas throughout the building. The basement public areas are served primarily by AHU-1, which conditions air before dumping it into the plenum (the space between ceiling panels and floor above). Similar to Spahr Library, diffusers in the ceiling allow the air to enter spaces. Heating: Steam is provided by the central plant to a hot water heat exchanger which serves HUB. A separate boiler in the basement produces steam for dining services use during the summer when the central plant is shut down. Cooling: Chilled water is provided via the central chiller plant on campus during the summer months. There are a number of smaller AHUs with minimum outdoor air rates that require cooling during the shoulder season and winter months. A chiller in the penthouse (picture to left) above the dining area provides chilled water for use in these select air handling units. Lighting: HUB lighting has been replaced using a phased approach. Lighting is predominantly linear fluorescent, with T12 fixtures remaining in portions of the lower level. Lighting control is primarily under manual control, and given the extended building schedule, lighting in some areas operates continuously. Refrigeration: Dedicated air-cooled condensers provide refrigeration for the walk-in coolers and freezers. The units are being relocated to the roof during replacement periods to allow reprogramming of the interior space. The majority of units remain in use throughout the year. Domestic Hot Water: A domestic hot water storage tank in the lower level mechanical room serves the building, with temperature maintained through the use of hot water circulation through the building loop. The tank is heated with steam from the central plant during the winter months and a local steam boiler during the summer months. Building Automation System: There is a Siemens Building Automation System (Apogee) for the building. The system was installed a few years ago but provides basic / rudimentary control of the AHUs for heating, cooling, damper control and fan start/stop, etc. There are a The Stone House Group Page 20

A motorized damper at the data room appears to remain open to separate zones. A condensate tank is leaking. Cap the draw-through humidifier at AHU-16 (abandoned) The chiller evaporator bypass was found open. Substantial air is leaking from the AH-3 supply air flex connections. No setback is available at the vestibule heater at Union Station, and the conditioned space is open to the plenum (no intended airflow is evident). Review opportunities to close the plenum opening, and consider setback control. All dining area T8 fixtures remain on while doors are locked and the space receives limited or no use. Reduce space lighting when the dining hall is not in service. Provide added control for the remaining AHUs in the BAS to provide monitoring and setpoint optimization. Outside air damper control may also be beneficial depending on intended operation. Combined heat and power generation (CHP / cogeneration) should be considered. A previous CHP project in HUB was unsuccessful, but improvements in technology may have re-opened the door to this possibility. Demand control ventilation, using sensors to determine how much outdoor air is supplied to the building spaces, should be considered. This type of control can significantly reduce heating and cooling load when lightly occupied. The Stone House Group Page 21
Dickinson College ASHRAE Level II Energy Audit Office areas in the basement should be isolated to ensure that heating and cooling loads are not affected by these spaces when they are unoccupied. Relief ducts for AHU-7 and AHU-8 should have dampers installed. Currently outside air is free to come in and conditioned air is free to leave. The Stone House Group Page 22

Appendix A Detailed ECM Descriptions (Library)
ECM-1002: Control of exhaust fans Description: Currently the building exhaust fans are controlled inefficiently. Instead of having them run constantly, we recommend that you control their operation with time clocks (or BAS) so that they run only while buildings are open, or with occupancy sensors which would turn them on only when the space is in use. During our inspections and interviews, it appeared that some exhaust fans run constantly, some perhaps not at all. We could not determine what areas some fans served. Although DC clearly make great efforts to avoid wasting heating and cooling energy if some exhaust fans are being controlled improperly, treated air is being wasted. Recapturing those savings is simple if time or occupancy control is instituted. Applicable Equipment / Buildings: Spahr, Waidner exhaust fans. O&M Impact: Oversight of control setting / programming will be required. Expected Life of ECM: Control equipment has an average life cycle of fifteen (15) years. Staff Training Requirements: None. Recommended M&V Method: Provide trend logs on BAS to monitor performance of fan systems. If time clocks are used then manually testing will be required. Rebates / Incentives Available: None.

ECM-1008: Replace electric heat with HW heat Description: Local electric heaters are a relatively inefficient way to provide heat. Replacing these units with hot water radiators (baseboard radiator units or radiant panels) or fanpowered variable air volume (VAV) boxes will have positive effects on user comfort as well as energy consumption. The Spahr staff area is the area in question. Even though the heaters are only on when personnel require it; you would save energy by switching to a different technology for the times when the system is actually running. The hot water radiator option will allow an energy saving strategy further detailed in ECM-1021. Applicable Equipment / Buildings: Spahr staff area. O&M Impact: None. Expected Life of ECM: VAVs have an average life expectancy of twenty (20) years. Hot water radiators have a slightly longer lifespan, averaging twenty-five (25) years. Staff Training Requirements: None. Recommended M&V Method: Periodic testing of HVAC system for proper operation. Rebates / Incentives Available: None.

ECM-1009: Convert pumps to variable flow Description: Currently the pumps send a constant volume of water through the system; whether demand is high or low this amount is always the same. Controlling pumps with a variable frequency drive (VFD) will slow the speed at which the motor must run when demand is light, resulting in a drop in electricity consumption. In support of this measure, the piping for the AHU unit coils served should be converted to twoway control with electronic actuation. Applicable Equipment / Buildings: Spahr pumps P-4, P-14, P-15. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Pump life cycle should also be increased because the VFD will prevent tangential forces on the pump shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: PPL s E-power Program offers an incentive of $30 per HP for qualifying projects.

ECM-1010: Convert chilled water pumps to variable flow Description: Currently the chilled water (CHW) pumps serving Waidner Library AHUs pump a constant volume of water through the CHW system regardless of the demand experienced at the equipment. Controlling these pumps with a variable frequency drive (VFD) will allow the system to adjust the amount of water flowing to meet but not exceed the requirements at any given time. This will result in less wear and tear on the pumps and reduced electricity consumption. The chilled water pumps for both Spahr and Waidner would all benefit from this upgrade. Applicable Equipment / Buildings: Waidner CHW pumps - P-16, P-17. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the inverter should have a life expectancy of fifteen (15) years. Pump life cycle should also be increased because the VFD will prevent tangential forces on the pump shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact.

ECM-1011: Convert heating hot water pumps to variable flow Description: Currently the heating hot water (HW) pumps serving Waidner pump a constant volume of water to equipment regardless of the demand. Controlling these pumps with a variable frequency drive (VFD) will allow them to reduce their run speed when not heavily loaded. This will result in less use of electricity. We noted that many of the distribution pumps (both HW and CHW) are installed with balancing valves that are set to block significant amounts of flow. Installing VFDs on the motors to control the amount of flow, while opening the balance valves all the way to maximize benefit of the VFD will eliminate the wastefulness of pumping at full power while throttling back the flow in the current manner. Applicable Equipment / Buildings: Waidner HW pumps - P-11, P-12. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Pump life cycle should also be increased because the VFD will prevent tangential forces on the pump shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact.

ECM-1012: Daylighting control for lighting Description: Why use electricity to produce light when there s plenty of it right outside being provided by the sun? By installing controls sensitive to the amount of daylight coming into the area, you can reduce reliance on bulbs and fixtures and cut energy use. This control senses the amount of sunlight present and ramps down the power output of the electric lights to the minimum level that will maintain the desired light levels in the area, or can switch them off entirely. There are many windows around the perimeter of the libraries; during our inspection on a bright, sunny day there was more than sufficient light coming from the sun alone yet the fixtures were all on. We understand that there is little or no localized lighting control, especially in Spahr: a small number of switches each turn on vast number of fixtures over broad areas. The inability to turn off lights in the vicinity of windows gives this ECM even more potential to provide savings. Applicable Equipment / Buildings: Spahr, Waidner light fixtures near perimeter windows. O&M Impact: Reducing the running hours of lighting or their power output will extend bulb life, making replacements less frequent. Expected Life of ECM: This type of control equipment has an average life cycle of fifteen (15) years. Staff Training Requirements: Operation and maintenance of sensors. Recommended M&V Method: None. Rebates / Incentives Available: Rebates are available through PPL E-power Program. ECM-1012 Daylighting Control Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 5,127 (6,719) 2.76 474 $ $ Installed Cost Simple Payback ROI $474 $6,000 12.7 years 8%
ECM-1013: Upgrade lighting fixtures Description: There is still some outdated lighting remaining in the building. We recommend the replacement of these with newer, more efficient models which use substantially less energy. The main culprit in these cases is usually the T-12 type fluorescent lamp. This was the industry standard in the recent past, but has been superseded by better technology today particularly T-8 and T-5 fluorescents. These offer improved efficiency without the increase in price to cutting-edge lighting such as LEDs. Thanks to recent renovations, this is by no means a widespread issue in the libraries. However, a few straggler T-12 fluorescent bulbs were found. These should be replaced with T-8 or better. Applicable Equipment / Buildings: Spahr, near elevator on bottom floor. O&M Impact: Reduced re-lamping. Expected Life of ECM: Lighting fixtures have an average life cycle of twenty (20) years. Staff Training Requirements: Lighting efficacy and spectrally enhanced lighting opportunities. Recommended M&V Method: Test with light sensor the footcandle reading before retrofit and after to ensure adequate light. Measure reduction in amp draw to fixtures as well. Rebates / Incentives Available: PPL E-power Program incentives at $6 per lamp are available. ECM-1013 Lighting Upgrade Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 329 0.2 34 $ $ Installed Cost Simple Payback ROI $34 $150 4.4 years 23%
ECM-1014: Use extended surface area filters in air handling units (AHUs) Description: When air handling units bring in outside air, they bring with it all manner of dirt, debris, and other unwanted matter. All AHUs have filters, but some filters are more effective than others. We recommend installing a filter with an extended surface area which will allow it to trap more foreign matter. Instead of being flat, ridges and valleys effectively broaden the surface in contact with the airstream. This additional area also adds significantly to the useful life of the filter, making replacement less frequent. By increasing the area of the filters, an AHU fan won t have to work as hard to push (or pull) air into the system; so it consumes less energy. Although they have a higher initial cost, extended surface air filters require a smaller pressure drop to pass air through them and consequently decrease the power needed by the fan motor. Applicable Equipment / Buildings: Waidner AHU-1, AHU-2. O&M Impact: Longer life of the new filters should mean that they need to be inspected less often. Inspections notwithstanding, they will also need to be changed less often. Expected Life of ECM: Filter life depends primarily on the amount of material in the local air and the numbers of hours the equipment is run. Staff Training Requirements: None. Recommended M&V Method: Static pressure measurements can confirm the expected reduction in drop across the filter. Rebates / Incentives Available: None. ECM-1014 Extended Surface Area Filters Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 18,785 11.42 744 $ $ Installed Cost Simple Payback ROI $744 $2,000 2.7 years 37%
ECM-1015: Occupancy / vacancy sensors for stack lighting Description: An ordinary light switch puts all responsibility for energy use on the users in a room, and takes away the power of your O&M staff to regulate electricity consumption there. Turning the lights on when you come in and turning them off again when going out is the best way to ensure that not a single watt too many is used; but it s far too easy to forget to flip the switch when you leave. Installing sensors to turn on the lights on when people are in a space (occupancy sensor) or to turn off the lights after no one is left (vacancy sensor) is the best way to bridge the gap between total user control (or lack thereof) and micromanagement by staff. Some of the book stack areas have lighting units suspended above aisles of books; these appear to remain on constantly, even if no one enters a given aisle during the course of an entire day. Putting sensors in these locations to turn on the lights only when in use will reduce electricity consumption. Applicable Equipment / Buildings: Spahr and Waidner: stack areas. O&M Impact: Reducing the running hours of lighting or their power output will extend bulb life, making replacements less frequent. Expected Life of ECM: Sensor life is estimated to be ten (10) years, but should lead to increased lamp life of the fixtures. Staff Training Requirements: Sensor inspection and testing training. Recommended M&V Method: Post-installation testing of sensor efficiency. Rebates/Incentives Available: PPL E-power Program incentive of $45 per sensor (not to exceed cost) is available. ECM-1015 Stack Lighting Occupancy Sensors Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 6,147 (5,666) 3.43 589 $ $ Installed Cost Simple Payback ROI $589 $2,850 4.8 years 21%
ECM-1016: Occupancy / Vacancy sensors for study rooms Description: An ordinary light switch puts all responsibility for energy use on the users in a room, and takes away the power of your O&M staff to regulate electricity consumption there. Turning the lights on when you come in and turning them off again when going out is the best way to ensure that not a single watt too many is used; but it s far too easy to forget to flip the switch when you leave. Installing sensors to turn on the lights on when people are in a space (occupancy sensor) or to turn off the lights after no one is left (vacancy sensor) is the best way to bridge the gap between total user control (or lack thereof) and micromanagement by staff. We noted that the study rooms in the libraries sometimes had lights on even though no one was using them. Putting sensors in these rooms to turn off the lights when not in use (or turn them on only when in use), will cut electricity consumption. Applicable Equipment / Buildings: Waidner: study rooms. O&M Impact: Reducing the running hours of lighting or their power output will extend bulb life, making replacements less frequent. Expected Life of ECM: Sensor life is estimated to be ten (10) years, but should lead to increased lamp life of the fixtures. Staff Training Requirements: Sensor inspection and testing training.

ECM-1020: Convert AC unit from vane regulation to VFD control Description: Currently the air conditioning unit controls the amount of supply air via an inlet guide vane. This opens and closes its dampers to allow more or less air in, depending on the current airflow requirements. However, installing a variable frequency drive (VFD) on the fan motor to take over this regulatory function will allow greater control and improved energy savings. The unit in question is the newest air conditioner in the Spahr penthouse, AC-4, which has a 15 horsepower (hp) motor. Applicable Equipment / Buildings: AC-4 O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Fan life cycle should also be increased because the VFD will prevent tangential forces on the fan shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: PPL s E-power Program offers an incentive of $30 per HP for qualifying projects.

ECM-1021: Spahr heating strategy Description: After converting Spahr perimeter electric heat to hydronic (baseboard radiators or radiant panel heat see ECM-1008), we recommend that the College install variable frequency drives (VFDs) on Spahr units AHU-1 and AHU-2. This will allow reduced airflow in the heating mode with proportional (PID) control relative to zone temperature. PID control is a method which uses feedback from a space to stable system behavior in close alignment with the desired setpoints. Alternatively, implement fan cycling for Spahr units AHU-1 and AHU-2 such that the fans remain off (and valves closed) when space temperature and levels are acceptable. Ensure that perimeter heat (now that it will be hot water) is the primary stage of heating. Savings can be realized through reduced fan and hot water energy consumption in the heating months. Comfort control can be improved through extended operation of perimeter heat. Applicable Equipment / Buildings: Spahr AHU-1, AHU-2. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of CO2 sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Fan life cycle should also be increased because the VFD will prevent tangential forces on the fan shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: PPL s E-power Program offers an incentive of $30 per HP for qualifying projects.

ECM-1022: Bypass Spahr ceiling lighting Description: Due to the nature of the ceiling construction in Spahr library, lighting changes are probably very difficult. However, the fixtures in the ceiling are not ideal because they are relatively inefficient and they are not controlled on a local level they all switch on regardless of what areas need to be on at any given time. We have identified an option for improvement over the current system. This strategy dovetails with ECM-1015, which discussed fitting the existing between-stack lighting with sensors to turn them on and off based on user presence. Taking that one step further, since it would be too expensive to take out the fixtures themselves, we suggest taking the lamps (bulbs) out of the existing fixtures and installing high-efficiency between-stack lighting with occupancy sensors to serve the entire stack area. Applicable Equipment / Buildings: Spahr library. O&M Impact: None. Expected Life of ECM: Lighting has an average life cycle of twenty (20) years. Wiring can be expected to last at least thirty-five (35) years. Staff Training Requirements: None. Recommended M&V Method: Test with light sensor the footcandle reading before retrofit and after to ensure adequate light. Measure reduction in amp draw to fixtures as well. Rebates / Incentives Available: PPL E-power Program incentives at $6 per lamp are available.

ECM-1026: Timed light switching Description: Similar to putting lights on a sensor-controlled switch, putting them on a time-controlled switch will reduce the amount of time during which they are consuming energy. A time control can be set to automatically turn lights off when a building or a space is not scheduled to be in use, and turn them back on again when users will be present. This ECM is for the collections area. We recommend putting the staff area lights on a timer so that are not on when the room is closed. One thing that might be worth noting is that turning off lights actually removes a heat source from a space. Subsequently, air handling equipment may cycle on more to make up the difference leading to a decrease in overall energy use and cost but an increase in heating energy consumption. Applicable Equipment / Buildings: Waidner library, collections area. O&M Impact: Additional switching should extend the life of the lighting by reducing runtime. Expected Life of ECM: Switches have an average life cycle of twenty-five (25) years. Staff Training Requirements: Using the timer. Recommended M&V Method: Verification of time control device operation. Rebates / Incentives Available: None.

ECM-1050: AHU-Radiant heat coordination Description: AHUs throughout Waidner and Spahr were observed in economizer operation while the radiant heating zones of both buildings were active. If the controls of the AHUs are telling them it is not necessary to heat, but the radiant heaters think it is time to turn on, a conflict exists that can potentially waste energy. Consider reviewing applicable setpoints and adjusting deadbands to reduce competition for temperature. ( deadband is the temperature range which is too hot to require heating but too cool to require cooling) This may mean setting AHUs to come on at a higher temperature or setting radiant heat to come on at a lower temperature. It should be possible to ensure that systems are acting in concert instead of against each other. Applicable Equipment / Buildings: Library AHUs and radiation heating. O&M Impact: Monitoring of setpoints or other control methods of AHUs and radiant heat. Expected Life of ECM: One (1) year. Staff Training Requirements: Train maintenance personnel on overall system operation and importance of having consistent setpoints for multiple systems serving a single space. Recommended M&V Method: Verification of system operation and control setpoints. Provide trend logs to monitor performance. Rebates / Incentives Available: None.

ECM-1136: Retrocommissioning (RCx) of HVAC Systems Description: Retrocommissioning (RCx) is a process of testing and measurement to verify that systems are still meeting their design intent. As years pass, even finely-tuned systems can slowly drift away from ideal conditions and it becomes harder for them to hit their target temperatures, airflows, and other setpoints. RCx acts as a tune-up, identifying where weaknesses and non-functionalities have developed and allows recommendations to be made that will improve system performance. The savings below are estimates based on our experience and independent studies of retrocommissioning. The costs include the commissioning itself, and also an estimate for remediation of problems found. Actual results will vary depending on what issues the process finds. Applicable Equipment / Buildings: All HVAC and lighting control systems in the Libraries. O&M Impact: RCx process will lead to improved system operation and a reduction in College staff O&M for troubleshooting issues. Expected Life of ECM: We recommend that systems be commissioned every 3-5 years. Staff Training Requirements: Staff training should occur for any changes to sequences of operation that are implemented to improve system performance as outlined in RCx process. Recommended M&V Method: Verify performance of building steam and chilled water meter and provide monthly reporting before and after Rx process. Rebates / Incentives Available: This ECM may be eligible for a custom rebate from PPL E- power Program if pursued.

ECM-1034: Fully open balance valves on pumps and run with VFD Description: Balancing valves are a common way to control the discharge flow of a pump that runs at a constant speed. If the pump is moving too much water, the valve restricts the output to keep the system balanced but this comes at the expense of running the pump at a higher speed than required. We recommend instead that the valve be fully opened and the pump be controlled through variable speed drive to modulate the amount of water being pumped. The 50 HP chilled water pumps, which we found set at 11.9 and 2.0 (i.e. 11.9% open and 2% open) could benefit greatly from being run at a lower speed rather than manually restricting the flow through the balance valve and using more energy. Applicable Equipment / Buildings: 50 HP chilled water Pumps in Rector. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Staff Training Requirements: VFD operation and maintenance. Recommended M&V Method: When measured over a period of time (not necessarily at any one particular instant), the power used by the motor will decrease. If this value is recorded it can be compared before and after the change. Rebates/Incentives Available: None.

ECM-1036: Additional insulation Description: Insulation serves two purposes when installed on piping systems: one is keeping hot surfaces from radiating away too much of the heat from their fluids, the other is to prevent cold surfaces from becoming exposed to warm humid air a condition which results in condensation. We recommend adding additional insulation to one or more locations in your system. Examples of good places for insulation include hot or cold water piping, hot water heaters, condensate tanks, steam traps, valves, cold water pumps, and more. In the case of the Rector Center, we particularly noted: - Removable insulating jackets should be added to steam gate valves. - Steam traps that do not operate based on temperature could also be insulated. Applicable Equipment / Buildings: The above listed equipment in Rector. O&M Impact: Insulation jackets will need to be configured to allow for removal for proper maintenance of the equipment. Expected Life of ECM: Insulation has an average life cycle of twenty (20) years. Staff Training Requirements: None. Recommended M&V Method: Not applicable. Rebates / Incentives Available: None.

ECM-1042: Use extended surface area filters in air handling units (AHUs) Description: When air handling units bring in outside air, they bring with it all manner of dirt, debris, and other unwanted matter. All AHUs have filters, but some filters are more effective than others. We recommend installing a filter with an extended surface area which will allow it to trap more foreign matter. Instead of being flat, ridges and valleys effectively broaden the surface in contact with the airstream. This additional area also adds significantly to the useful life of the filter, making replacement less frequent. By increasing the area of the filters, an AHU fan won t have to work as hard to push (or pull) air into the system; so it consumes less energy. Although they have a higher initial cost, extended surface air filters require a smaller pressure drop to pass air through them and consequently decrease the power needed by the fan motor. Applicable Equipment / Buildings: Rector AHUs. O&M Impact: Longer life of the new filters should mean that they need to be inspected less often. Inspections notwithstanding, they will also need to be changed less often. Expected Life of ECM: Filter life depends primarily on the amount of material in the local air and the numbers of hours the equipment is run. Staff Training Requirements: None. Recommended M&V Method: Static pressure measurements can confirm the expected reduction in drop across the filter. Rebates / Incentives Available: None.

ECM-1044: Control of autoclave exhaust fan Description: Currently your exhaust fans seem to be controlled inefficiently. Instead of having them run constantly, we recommend that you control their operation with time clocks so that they run only while buildings are open, or with sensors which would turn them on only when the autoclave is in use. During our inspections and interviews, it appeared that exhaust fan EF-13 runs constantly, regardless of the condition of the space it serves. Applicable Equipment / Buildings: Rector EF-13. O&M Impact: Oversight of control setting / programming will be required. Expected Life of ECM: Control equipment has an average life cycle of fifteen (15) years. Staff Training Requirements: None. Recommended M&V Method: BAS trend log to verify performance of system and to ensure cycling off during unoccupied hours. Rebates / Incentives Available: None.

ECM-1045: BAS control optimization Description: Controlling equipment through the building automation system (BAS) has many advantages over localized control. With data flowing into a central location, your operations staff can have more information at their fingertips and will be able to make better decisions about how to run equipment and better conclusions about how the system is operating. We found that the energy recovery wheels (ERW) on the AHUs in Rector are not currently controlled optimally by the BAS system. We recommend that they be monitored and controlled based on the actual discharge air temperature (DAT) setpoint, thereby increasing the efficiency of operation. The ERWs were observed with efficiencies below 30% due to current control for mixed air temperature setpoint. Current conditions were noted to cause steam heat to come on unnecessarily. Applicable Equipment / Buildings: Energy recovery wheels in Rector AHUs. O&M Impact: None. Expected Life of ECM: A building management system generally has a life cycle of about fifteen (15) years. Newer technology and software is constantly being developed. Staff Training Requirements: BAS operation and control method to optimize performance of heat wheels. Recommended M&V Method: Provide BAS trend logs and reporting to monitor performance of wheel and control set points. Rebates / Incentives Available: None.

ECM-1048: Condensing Hot Water Heater Description: A condensing hot water heater offers an advantage over a traditional gas-fired unit because it utilizes the exhaust gas from the burner to preheat incoming cold water. This boosts the efficiency of the unit to a level much higher than possible in a standard gas fired heater. It is recommended that the current hot water generation be replaced with these higher efficiency units. Applicable Equipment / Buildings: Rector domestic hot water heater(s). O&M Impact: Monitoring of operation and hot water temperature setpoint control to optimize system performance. Expected Life of ECM: Hot water heaters have an average life cycle of fifteen (15) years. Staff Training Requirements: Cleaning and maintenance of unit, and checking of operation.

ECM-1052: Optimize daylighting control in labs Description: Why use electricity to produce light when there s plenty of it right outside being provided by the sun? By installing controls sensitive to the amount of daylight coming into the area, you can reduce reliance on bulbs and fixtures. These controls sense the amount of sunlight present and ramp down the power output of the electric lights to the minimum (not necessarily off ) that will maintain the desired light levels in the area. Lab space in Rector already uses daylighting control and has lights that are on dimmable ballasts. However, we noted that the room light levels remain high to reduce fluctuations caused by passing clouds, etc. We recommend that you reduce the daylighting minimum threshold and reduce the dimming rate to help account for sudden changes without relying on simply keeping lights on at high levels. Additional benefits can be realized by reducing the occupancy sensor minimum runtime. Applicable Equipment / Buildings: Rector labs lighting. O&M Impact: Reducing the running hours or lighting output will extend bulb life, making replacements less frequent. Expected Life of ECM: This type of control has an average life cycle of fifteen (15) years. Staff Training Requirements: Staff should be trained on the room dimming systems and operation of daylight sensors. Recommended M&V Method: Verify performance before and after with light meter in space to ensure adequate lighting for occupants. Rebates / Incentives Available: None system is already installed.

ECM-1054: Energy miser for vending machines Description: A vending machine is basically a refrigerator; and refrigerators use a lot of energy. Since the contents are nonperishable, there is no need to keep them at the absolute lowest possible temperature while no one is around to drink them (with the exception of dairy products). An energy miser connects the machine to an infrared sensor that detects when no one is around and turns off the power. The better miser units periodically allow a brief cooling cycle to meet the minimum requirements set by beverage manufacturers for their drinks sale. In an academic building that is not occupied at night, this type of measure makes a lot of sense because no one is around to purchase drinks for long stretches of time. Student polls at Dickinson support the use of this particular energy conservation measure. Please consult the vendor before installing sensors. Applicable Equipment / Buildings: Rector vending machines. O&M Impact: Reduced run hours will extend life of vending machine compressors. Expected Life of ECM: This type of sensor has an average life cycle of fifteen (15) years. Staff Training Requirements: Sensor operation and control methodology. Recommended M&V Method: Timers can be installed to monitor vending machine run hours to verify performance after sensor installation. Rebates / Incentives Available: None.

ECM-1055: Optimize daylighting control in lobby Description: Why use electricity to produce light when there s plenty of it right outside being provided by the sun? By installing controls sensitive to the amount of daylight coming into the area, you can reduce reliance on bulbs and fixtures. These controls sense the amount of sunlight present and ramp down the power output of the electric lights to the minimum (not necessarily off ) that will maintain the desired light levels in the area. Like the labs (see ECM-1052), lobby space in Rector already uses daylighting control. However, we noted that the room light level thresholds could be adjusted. Please also ensure that all required circuits are connected. Applicable Equipment / Buildings: Rector lobby lighting. O&M Impact: Reducing the running hours or lighting output will extend bulb life, making replacements less frequent. Expected Life of ECM: This type of control has an average life cycle of fifteen (15) years. Staff Training Requirements: Staff should be trained on the room dimming systems and operation of daylight sensors.

ECM-1056: Occupancy / vacancy sensors in labs Description: In lab spaces the savings are amplified as the occupancy/vacancy sensors allow the lab airflow rate (air changes per hour or ACH ) to be reduced during unoccupied periods. The savings for this project in the science labs are listed below, but we consider the more expansive measure, ECM-1118, to be indicative of the full savings potential in the labs. The results shown here should not be considered additive. Applicable Equipment / Buildings: Science labs in Rector. O&M Impact: Lower airflows result in reduced wear and tear on equipment and less frequent filter changes, etc. Expected Life of ECM: Fifteen (15) years. Staff Training Requirements: Train staff on control strategy and significance of reducing ACH rates and temperatures during unoccupied hours. Recommended M&V Method: Provide trend logs of lab airflow and temperatures before and after sensor installation to verify proper operation. Rebates / Incentives Available: This ECM may be eligible for a custom incentive from PPL E- power Program.

ECM-1058: Optimize control of AHU-V-1 (Vivarium) Description: Temperature setpoints controlling the heat plate (dampers) and steam do not appear optimized for discharge air temperature control. Applicable Equipment / Buildings: Rector AHU-V-1. O&M Impact: None. Expected Life of ECM: A building management system generally has a life cycle of about fifteen (15) years. Newer technology and software is constantly being developed. Staff Training Requirements: BAS operation and control method to optimize performance of heat wheels.

ECM-1059: Retrocommissioning (RCx) of HVAC Systems Description: Retrocommissioning (RCx) is a process of testing and measurement to verify that systems are still meeting their design intent. As years pass, even finely-tuned systems can slowly drift away from ideal conditions and it becomes harder for them to hit their target temperatures, airflows, and other setpoints. RCx acts as a tune-up, identifying where weaknesses and non-functionalities have developed and allows recommendations to be made that will improve system performance. It was noted that a number of sensors and control sequences in Rector appear to be experiencing problems, as well as valves and dampers which are not functioning properly. RCx can act as a first step to solving these issues. Retrocommissioning would also open up the floor to a close analysis of lab airflows, which will warrant not only verification but possibly a rethinking of the design requirements. The costs and savings below are estimates based on our experience and independent studies of retrocommissioning. Actual results will vary depending on what issues the process finds. Applicable Equipment / Buildings: All HVAC and lighting control systems in Rector. O&M Impact: RCx process will lead to improved system operation and a reduction in College staff O&M for troubleshooting issues. Expected Life of ECM: We recommend that systems be commissioned every 3-5 years. Staff Training Requirements: Staff training should occur for any changes to sequences of operation that are implemented to improve system performance as outlined in RCx process. Recommended M&V Method: Verify performance of building steam and chilled water meter and provide monthly reporting before and after Rx process. Rebates / Incentives Available: This ECM may be eligible for a custom rebate from PPL E- power Program if pursued.

ECM-1117: Unoccupied setback Description: There is no need to have temperature or humidity conditions held constantly to occupancy requirements when no one is using a space. We recommend allowing the system to setback to a lower setpoint at night or during other low- or non-use periods. For example, if a normal space temperature heating setpoint is 72 F when occupied, then during unoccupied times it should not be a problem to let the space temperature drift down to 60 F. Even if students are coming in to use the building after regular class hours, airflows and temperatures in offices can certainly be set back. Even common areas could have their settings relaxed a little, possibly in connection with occupancy sensors. Applicable Equipment / Buildings: Rector. O&M Impact: None. Expected Life of ECM: Ten (10) years. Staff Training Requirements: None. Recommended M&V Method: Provide BAS trend logs to verify proper operation. Rebates / Incentives Available: None. ECM-1117 Unoccupied Setback Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 1,756 96,306 6.18 990 $ $ Installed Cost Simple Payback ROI $990 $2,000 2.0 years 49%
ECM-1118: Volatile Organic Compound (VOC) Demand controlled ventilation for labs Description: Conventional lab design requires high levels of ventilation air to minimum air change rates regardless of the current conditions or chemical exposure in the space. The quantity of air changes varies between different standards, some of which refute the air change method due to the high and arbitrary volumes required, which increase noise, energy consumption and the capital cost of ventilation systems due to increased capacity requirements. In the same method as a demand controlled ventilation sequence, VOC sensors in the lab can be installed to adjust the airflow to ensure that conditions are acceptable, resetting to the maximum only in the event of chemical spillage or high exposure. At other times, the airflow will control at a lower ventilation rate, and increase as required for space cooling. Implementation of this project will yield the highest savings once the hood minimum flows are reduced, such that these will not be a limiting factor in the reduction of airflow. Coordinating the ventilation of lab space with the readings from sensors represents an opportunity to reduce the amount of airflow and cut down on unnecessarily conditioning air. The figures below include savings associated with ECM 1057. This project can be considered to supersede ECM- 1056. Applicable Equipment / Buildings: Rector labs. O&M Impact: Re-commissioning of VOC sensor and controller. Expected Life of ECM: Sensors have an average life cycle of fifteen (15) years. Staff Training Requirements: Determine acceptable VOC levels. Recommended M&V Method: None. Rebates/Incentives Available: None.

ECM-1133: Synchronous belt drive Description: In most air handling equipment, a motor is not directly in contact with the fan it is turning. A rubber belt transmits the power of the motor into the rotation of the fan. Ordinary smooth fan belts rely on the distance between the motor shaft and the fan shaft to produce a tension to keep the belt in place. However, under demanding conditions, these smooth belts can slip and some of the power will be lost. This can add up to several percent over the course of a year. A synchronous belt (see picture) is more like a bicycle chain; it has teeth that mesh with teeth in pulleys on the shafts to eliminate slippage and ensure that all the power in the motor shaft goes into the fan shaft. New pulleys would be required, and synchronous belts are more expensive than regular smooth belts but by preventing power loss payback is quickly achieved. Because these belts operate at a lower tension, they could be subject to problems when a VFDpowered unit ramps up or performs a soft start / stop. Implementing this change only on redundant units would add a level of caution. Applicable Equipment / Buildings: Rector AHUs. O&M Impact: Installing a synchronous drive will reduce the frequency of belt adjustments and replacements; it is also likely to reduce the forces on the motor and fan, resulting for longer service life of that equipment as well. Expected Life of ECM: Staff Training Requirements: Installation and maintenance of synchronous belts. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates/Incentives Available: None.

ECM-1060: Occupancy / vacancy sensors for lighting - corridors Description: An ordinary light switch puts all responsibility for energy use on the users in a room, and takes away the power of your O&M staff to regulate electricity consumption there. Turning the lights on when you come in and turning them off again when going out is the best way to ensure that not a single watt too many is used; but it s far too easy to forget to flip the switch when you leave. For many users it s not even a matter of forgetting it s a matter of not being aware of that responsibility or not caring. Installing sensors to turn on the lights when people are in a room (occupancy) or to turn off the lights after no one is left (vacancy) is the best way to bridge the gap between total user control (or lack thereof) and time-consuming micromanagement by staff. Adams Hall features bi-level lighting. Half the lights are controlled by one switch and half are controlled by another. Adding occupancy / vacancy sensors to one level of lighting would allow a certain level of lighting to remain on at all times (if necessary) while lighting above and beyond that would turn off when not necessary. Applicable Equipment / Buildings: Adams corridors. O&M Impact: Reduced re-lamping requirements. Expected Life of ECM: Sensor life is estimated to be ten (10) years, but should lead to increased lamp life of the fixtures. Staff Training Requirements: Sensor inspection and testing training.

ECM-1064: Isolate boilers Description: When multiple boilers are connected in parallel, the heating capacity of the system can be maximized but waste must be avoided. If only one boiler is operating, the second should be isolated by closing the valves at connections to prevent hot water from cycling through it. This creates unnecessary losses from heat radiation. In Adams Hall, both boilers remain hot although they appear to be installed with significant redundancy. During times when one boiler is sufficient, it is suggested that redundant boilers are isolated from each other at valves to reduce radiant losses and avoid increased lead boiler energy use from unnecessary blending. Applicable Equipment / Buildings: Adams boilers. O&M Impact: Unless this control is automated, staff will have to monitor the boiler usage and open / close valves as necessary to meet demand. Expected Life of ECM: Permanent. Staff Training Requirements: Boiler valving. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1065: Upgrade lighting Description: Some outdated lighting still remains in the building. We recommend these be replaced with newer, more efficient models that use substantially less energy. The main culprit in these cases is usually the T-12 type fluorescent lamp. This was the industry standard in the recent past, but has been superseded by better technology today particularly T-8 and T-5 fluorescents. These offer improved efficiency without the increase in price to cutting-edge lighting such as LEDs. The corridor lighting is still T-12, and should be upgraded to the more efficient T-8 or T-5 models. Applicable Equipment / Buildings: Adams corridors. O&M Impact: Reduced re-lamping. Expected Life of ECM: Lighting fixtures have an average life cycle of twenty (20) years. Staff Training Requirements: Lighting efficacy and spectrally enhanced lighting opportunities. Recommended M&V Method: Adams electric meter or additional submeter. Rebates / Incentives Available: PPL E-power Program incentives at $6 per lamp are available.

Installing sensors to turn on the lights on when people are in a room (occupancy) or to turn off the lights after no one is left (vacancy) is the best way to bridge the gap between total user control (or lack thereof) and time-consuming micromanagement by staff. Adams Hall could also use this feature in dorm rooms themselves. We further suggest that it could be feasible in laundry, vending, and support areas. Applicable Equipment / Buildings: O&M Impact: Reduced re-lamping requirements. Expected Life of ECM: Sensor life is estimated to be ten (10) years, but should lead to increased lamp life of the fixtures. Staff Training Requirements: Sensor inspection and testing training.

ECM-1071: Sink aerators Description: Installing an aerator in a faucet can reduce the amount of water being used without reducing the effectiveness of the discharged flow. An aerator introduces air into the water stream to increase the effective volume of the stream while decreasing the proportion of water. Cutting down the amount of water used also cuts down the amount of heated water which much be produced, creating energy savings related to fuel costs. Interviews with staff indicate that aerators are used in select buildings but are sometimes removed by students. However, aerators are still encouraged and should be replaced when necessary they pay for themselves very quickly. In this particular case, under counter aerators, which are not removable, may be considered. Applicable Equipment / Buildings: Sinks. O&M Impact: Requires installation and periodic replacement. Expected Life of ECM: Five (5) years. Staff Training Requirements: General observation of lavatories to replace aerators as needed. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1073: Hot water recirculation temperature setback Description: The domestic hot water recirculation pump aquastat is currently set at 130 F and is causing the pump to run continuously. A recirculation pump distributes hot water through the system even when hot water is not being used in order to reduce the delay distributes when it may not be necessary. However, a constant flow 24 hours a day may not be necessary. Lowering the temperature limit to reduce pump operation, pipe losses and water heater cycling is recommended. This is a no-cost measure just turn down the dial and start saving. Applicable Equipment / Buildings: Recirculation pump in Adams. O&M Impact: None. Expected Life of ECM: Permanent.

ECM-1075: Condensing boilers Description: Replacement of current boilers with condensing boilers is recommended. Condensing boiler technology improves efficiency over a normal design by capturing heat from the water vapor produced by combustion. Even small increases in efficiency can generate important fuel savings. However, due to the current rate structure, retaining one dual-fuel boiler may be advantageous to ensure continued interruptible rates. Applicable Equipment / Buildings: Adams boilers. O&M Impact: Monitoring of operation and hot water temperature setpoint control to optimize system performance. Expected Life of ECM: Boilers have an average life cycle of thirty-five (35) years.

ECM-1121: Tie into main electric meter Description: An analysis of the cost of all utilities on campus shows that the main electric meter rate is significantly cheaper than the rates being paid at the various smaller meters. Consolidating some of the independent connections could result in overall savings. The savings below are based on the energy cost data we reviewed as part of the audit. The main meter rate was, depending on the year, 20%-50% lower than the outlying meter rates. Due to the cost of electrical installations, implementation of this ECM would be much more appealing if Rush Campus as a whole, instead of just Adams, was consolidated into the main meter.

ECM-1081: Isolate boiler Description: When multiple boilers are connected in parallel, the heating capacity of the system can be maximized but waste must be avoided. If only one boiler is operating, the second should be isolated by closing the valves at connections to prevent hot steam from cycling through it. This creates unnecessary losses from heat radiation. The boiler in the HUB basement, which is used primarily for kitchen hot steam during months when the central boiler is not in operation, should be isolated from the system when not in use. Applicable Equipment / Buildings: HUB boilers. O&M Impact: Must be automated at this location. Staff will have to monitor the boiler usage and open / close valves as necessary to meet demand. The cost below includes automatic valves under direct digital control (DDC). Expected Life of ECM: Fifteen (15) years. Staff Training Requirements: Valve locations and intended operation. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1083: Additional insulation Description: Insulation serves two purposes when installed on piping systems: one is keeping hot surfaces from radiating away too much of the heat from their fluids, the other is to prevent cold surfaces from becoming exposed to warm humid air a condition which results in condensation. We recommend adding additional insulation to one or more locations in your system. Examples of good places for insulation include hot or cold water piping, hot water heaters, condenser tanks, steam traps, valves, cold water pumps, and more. In the case of the HUB, we particularly noted: - Removable insulation jackets should be added to steam gate valves. - Steam traps which do not operate based on temperature could also be insulated. Applicable Equipment / Buildings: The above listed equipment in HUB. O&M Impact: None. Expected Life of ECM: Insulation has an average life cycle of twenty (20) years. Staff Training Requirements: None. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1084: Time control on hot water recirculation pump Description: The purpose of a hot water recirculation pump is to keep hot water flowing through the system so that the potential delay is greatly reduced. However, if a building has significant periods of time when it is unoccupied, setting the recirculation back by adding time control to the pump, which turns it off during specified hours, will result in saving energy that might otherwise be lost due to distribution losses. Less fuel will be burned producing the heat, and pump motors will also have to run less. The savings calculated below may vary depending on the extent to which setback can be implemented. Applicable Equipment / Buildings: HUB boiler recirculation pump. O&M Impact: Required oversight of its operation may be reduced. Expected Life of ECM: Timer controls have an average life cycle of fifteen (15) years. Staff Training Requirements: Use of timer. Recommended M&V Method: None. Rebates / Incentives Available: None. Electricity (kwh) ECM-1084 Hot Water Recirculation Timer Gas Chilled Hot Water (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 6,599 0.56 95 $ $ Installed Cost Simple Payback ROI $95 $450 4.8 years 21%
ECM-1085: Convert heating hot water pumps to variable flow Description: Currently HUB heating hot water pumps send a constant amount of water to equipment regardless of the demand. Controlling these pumps with a variable frequency drive (VFD) will allow a reduction in speed when not heavily loaded. This will result in less use of electricity. To be more specific, we noted that many of the distribution pumps (both HW and CHW) are fitted with balancing valves that are set to block significant amounts of flow. In this way, even though the motor is running at full speed, only the necessary amount of liquid is pumped. Installing VFDs on the motors will eliminate the wastefulness of pumping at full power while throttling back the flow in the current manner. Applicable Equipment / Buildings: Two 15hp hot water pumps in HUB. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: Rebates are available for VFDs through the PPL E-power Program.

ECM-1086: Water-side economizer Description: A normal water chiller utilizes a refrigeration cycle to cool water for distribution throughout the system. A water-side economizer utilizes chilled water heat exchange directly to the exterior when outside temperatures are low enough to chill water without inputting any additional energy. In cases where cooling may be required during the heating season (when outside temperatures are low), this can be implemented with success. Since the HUB needs cooling even during winter months, this is an attractive option for energy savings. An alternative method might be to use the make-up air unit (MAU) intake to provide the cooling for chilled water while simultaneously preheating the MAU air. Applicable Equipment / Buildings: 60-ton unit in HUB. O&M Impact: Dry cooler maintenance. Expected Life of ECM: Twenty (20) years. Staff Training Requirements: Dry cooler maintenance and system switchover. Recommended M&V Method: Flow and temperature metering to demonstrate dry cooler heat rejection. Rebates / Incentives Available: ECM may be eligible for custom rebate through PPL E-power Program. ECM-1086 Water-side Economizer Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 22,990 13.97 2,380 $ $ Installed Cost Simple Payback ROI $2,380 $22,500 9.5 years 11%
ECM-1088: Demand control ventilation Description: sensors act as occupancy sensors for an HVAC system. Since humans exhale carbon dioxide when they breathe, the presence of this gas indicates that people are present in a space and that ventilation is required to keep them supplied with fresh air. This is known as demand controlled ventilation (DCV). Furthermore, indexing ventilation to concentrations of keeps the system from bringing in outdoor air when it is not needed. Since outdoor air is usually conditioned (i.e. heated or cooled) after it is brought in, reduced outdoor air results in less energy expended on heating and cooling. This may be a good option for the areas in HUB s basement served by AHU-1. We also recommend that a control sequence for this mode of operation be made available at the front end of the building automated system (BAS). Exact savings for this ECM will depend on the sequence of operations that would be written, including the minimum fresh air intake damper control. Applicable Equipment / Buildings: HUB HVAC system. O&M Impact: Expected Life of ECM: Sensors have an average life cycle of fifteen (15) years. Staff Training Requirements: Recommended M&V Method: None. Rebates/Incentives Available: None. ECM-1088 Demand Control Ventilation Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 964,335 1,205,544 650.06 109,928 $ $ Installed Cost Simple Payback ROI $109,928 $263,250 2.4 years 42%
ECM-1089: Sink aerators Description: Installing an aerator in a faucet can reduce the amount of water being used without reducing the effectiveness of the discharged flow. An aerator introduces air into the water stream to increase the effective volume of the stream while decreasing the proportion of water. Cutting down the amount of water used also cuts down the amount of heated water which much be produced, creating additional savings related to fuel costs. The sinks we tested in the HUB were flowing at 2.2-2.5 gallons per minute (gpm). This is on par with the International Plumbing Code standard for a private residence but it is well over the public restroom standard of 0.5 gpm. Interviews with staff indicate that aerators are used in select buildings but are sometimes removed by students. However, aerators are still encouraged and should be replaced when necessary they pay for themselves very quickly. In this particular case, under counter aerators, which are not removable, may be considered. Applicable Equipment / Buildings: Sinks. O&M Impact: Requires installation and periodic replacement. Expected Life of ECM: Five (5) years. Staff Training Requirements: General observation of lavatories to replace aerators as needed. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1092: Plastic strip curtains Description: Most people are familiar with the curtains consisting of thick plastic strips often found in commercial walk-in coolers and freezers. These curtains effectively reduce the amount of air that enters or leaves the interior when the door is opened, thereby saving energy because less air has to be re-cooled. We recommend installing these on your walk-in units. They already exist on two of the units in HUB, the numbers below reflect the addition to the remaining locations. Applicable Equipment / Buildings: HUB walk-in cooler / freezers. O&M Impact: Periodic cleaning and replacement. Expected Life of ECM: Eight (8) years. Staff Training Requirements: None. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1094: Condensing boiler Description: Replacement of current boilers with condensing boilers is recommended. Condensing boiler technology improves efficiency over a normal design by capturing heat from the water vapor produced by combustion. Even small increases in efficiency can generate important fuel savings. However, due to the current rate structure, retaining one dual-fuel boiler may be advantageous to ensure continued interruptible rates. Utilizing a condensing boiler in the HUB may have even greater advantages due to its primary use taking place during the summer. O&M Impact: Monitoring of operation and hot water temperature setpoint control to optimize system performance. Expected Life of ECM: Boilers have an average life cycle of thirty-five (35) years. Staff Training Requirements: Maintenance and operation of condensing boiler. Recommended M&V Method: Perform combustion efficiency tests annually to verify performance. Rebates / Incentives Available: None. Electricity (kwh) ECM-1094 Condensing Boiler Gas Chilled Hot Water (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 272,219 14.46 2,643 $ $ Installed Cost Simple Payback ROI $2,643 $30,000 11.4 years 9%
ECM-1097: Perimeter radiation schedule Description: We recommend that scheduling control be provided for your perimeter radiation. Setting up a time schedule in addition to thermostatic control will create an extra level of setback that can be utilized to save energy during unoccupied hours. Currently the HUB perimeter radiation loop uses a stand-alone thermostat for control and is enabled whenever the central plant is on. Applicable Equipment / Buildings: HUB basement perimeter radiation. O&M Impact: Periodic scheduling with seasonal occupancy changes. Expected Life of ECM: Fifteen (15) years. Staff Training Requirements: None. Recommended M&V Method: Provide trend data of new direct digital control (DDC) point. Rebates / Incentives Available: None.

ECM-1099: Convert chilled water pumps to variable flow Description: Currently the chilled water (CHW) pumps distribute a constant amount of water through the CHW system regardless of the demand experienced at the equipment. Controlling these pumps with a variable frequency drive (VFD) will allow the system to adjust the amount of water flowing to meet but not exceed the requirements at any given time. This will result in less run time for the pumps and reduce electricity consumption. Applicable Equipment / Buildings: HUB chilled water pumps. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Fan life cycle should also be increased because the VFD will prevent tangential forces on the fan shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: Rebates are available through PPL s E-power Program. ECM-1099 CHW Pump VFD Electricity Gas Chilled Hot Water (kwh) (MBTU) Water (BTU) (BTU) Oil (gal) (mtons) $ Dollars 29,483 17.92 3,052 $ $ Installed Cost Simple Payback ROI $3,052 $9,500 3.1 years 32%
ECM-1100: Occupancy / Vacancy sensors for lighting Description: An ordinary light switch puts all responsibility for energy use on the users in a room, and takes away the power of your O&M staff to regulate electricity consumption there. Turning the lights on when you come in and turning them off again when going out is the best way to ensure that not a single watt too many is used; but it s far too easy to forget to flip the switch when you leave. For most users it s not even a matter of forgetting it s a matter of not being aware of that responsibility. Installing sensors to turn on the lights when people are in a room (occupancy) or to turn off the lights after no one is left (vacancy) is the best way to bridge the gap between total user control (or lack thereof) and micromanagement by staff. The HUB has bi-level lighting in some areas. Adding occupancy / vacancy sensors to one level of lighting would allow some lighting to remain on at all times (if necessary) while lighting above and beyond that would turn off when not necessary. Applicable Equipment / Buildings: HUB lower level. O&M Impact: Reduced re-lamping requirements. Expected Life of ECM: Sensor life is estimated to be ten (10) years, but should lead to increased lamp life of the fixtures. Staff Training Requirements: Sensor inspection and testing training. Recommended M&V Method: Post-installation testing of sensor efficiency. Rebates/Incentives Available: Rebates are available through PPL s E-power Program.

ECM-1102: Energy miser for vending machines Description: A vending machine is basically a refrigerator, and refrigerators use a lot of energy. Since the contents are nonperishable, there is no need to keep them at the absolute lowest possible temperature while no one is around to drink them (with the exception of dairy products). An energy miser connects the machine to an infrared sensor that detects when no one is around and turns off the power. The better miser units periodically allow a brief cooling cycle to meet the minimum requirements set by beverage manufacturers for their drinks sale. Even in a dormitory, there will still be stretches of time when no one is around to purchase drinks. Student polls at Dickinson support the use of this particular energy conservation measure. Please consult vendor prior to installation. Applicable Equipment / Buildings: Vending machines in HUB. O&M Impact: Reduced run hours will extend life of vending machine compressors. Expected Life of ECM: This type of sensor has an average life cycle of fifteen (15) years. Staff Training Requirements: Sensor operation and control methodology. Recommended M&V Method: Timers can be installed to monitor vending machine run hours to verify performance after sensor installation. Rebates / Incentives Available: None.

ECM-1103: LED lights in walk-in coolers Description: LEDs, while always a good choice for lighting needs, are particularly suited to cold temperature applications like a walk-in cooler or freezer. They can provide two advantages over incandescent or even fluorescent lamps: LEDs generate less heat than other kinds of lighting, and they retain excellent efficiency at low temperatures. We recommend the switch is made to this superior technology. Applicable Equipment / Buildings: HUB kitchen walk-in coolers and freezers. O&M Impact: Reduced re-lamping. Expected Life of ECM: Ten (10) years. Staff Training Requirements: None. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1104: Snow melt pump control Description: It is recommended that some kind of control is installed on the snow melting system to ensure that it is running only when it needs to be. This could take the form of a snow sensor or connection to the BAS which can read local weather conditions and command the melt system accordingly. Applicable Equipment / Buildings: Snow melt pump system at service ramp in back of HUB. O&M Impact: Sensor cleaning, depending on type selected. Expected Life of ECM: Fifteen (15) years. Staff Training Requirements: Snow melt controller. Recommended M&V Method: Monitoring of pump run time and temperature drop. Rebates / Incentives Available: None.

ECM-1107: Kitchen hood VFD control Description: We recommend increasing the control over kitchen hoods by adding variable frequency drive (VFD) control to the fan motors. This will allow full ventilation when necessary while cooking; but also permit setback to a lower level of power usage when equipment is not actively in use. One example of this type of control would be an infrared sensor which detects heat from the cooking equipment. When hot, the hood fans would ramp up to an appropriate speed. When cool, the fans would slow down to save energy. Applicable Equipment / Buildings: HUB kitchen hoods. O&M Impact: A Preventative Maintenance schedule should be added for periodic calibration of sensors and inspecting / testing of the VFD. Expected Life of ECM: With proper maintenance and periodic inspection, the VFD should have a life expectancy of fifteen (15) years. Fan life cycle should also be increased because the VFD will prevent tangential forces on the fan shaft that decrease bearing and seal life. Staff Training Requirements: Training on VFD operation and maintenance. Recommended M&V Method: Pre- and post-installation measurement of power should be performed to verify savings impact. Rebates / Incentives Available: None.

ECM-1110: Disable AHU-7 electric heating coils Description: We recommend disabling electric heating coils associated with AHU-7. Installing standalone variable volume and temperature (VVT) diffusers, or BMS-controlled dampers with a variable volume sequence, will result in more efficient use of energy. This measure, if taken, will also allow for the use of a variable frequency drive (VFD) with this unit. Applicable Equipment / Buildings: HUB AHU-7. O&M Impact: Periodic re-commissioning of installed system. Expected Life of ECM: Fifteen (15) years. Staff Training Requirements: New system controls. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1112: Address negative building pressure Description: We found that the building is experiencing a negative air pressure. This means that more air is being exhausted via ductwork than is being taken in through the ventilation system. Since unequal pressures naturally try to equalize, outside air will infiltrate through doors, windows, and any openings in the building exterior. Such infiltration contributes additional load during heating or cooling of interior spaces. We recommend starting with a review of kitchen make-up air options. There may be an opportunity to use building air from other systems to reduce infiltration of outdoor air. If the Dining Room AHU OA minimum is to remain at zero and the MAU off, utilize unconditioned internal make-up air (short circuit supply) for partial make-up. Install side panels and canopies at the hoods to reduce spillage and exhaust requirements. Final savings will depend on the exact approach used and the design parameters chosen. Applicable Equipment / Buildings: HUB. O&M Impact: Monitoring of building pressure. Expected Life of ECM: Twenty (20) years. Staff Training Requirements: Relationship of building ventilation and exhaust system. Recommended M&V Method: None. Rebates / Incentives Available: None.

ECM-1113: Convert AHU from hot / cold deck system to VAV Description: An air handling unit (AHU) hot / cold deck system is one where the AHU has a dedicated discharge for hot air (with a heating coil) and a separate discharge for cold air (with a cooling coil). This type of system can easily waste energy by cooling and heating at the same time. To avoid this, we recommend changing to a variable air volume (VAV) terminal box setup. When we examined the control system, we discovered that two HUB units, AHU-3 and AHU-5, have this dual system in place. During a check of AHU-5 the unit was introducing excess air in the economizer mode while the hot deck heating valve was open. That implies a function of heating, but it was also allowing outdoor air in through its cold air ducting. Installation of VAVs would avoid this issue. The numbers below represent a programming upgrade for hot and cold deck temperature resets to limit simultaneous heating and cooling. Applicable Equipment / Buildings: HUB AHU-3 and AHU-5. O&M Impact: Periodic re-commissioning. Expected Life of ECM: VAV boxes have an average life cycle of twenty (20) years. Staff Training Requirements: Since there are existing VAV systems elsewhere on campus, no additional training should be required Recommended M&V Method: Trend data of heating and cooling positions valve.

ECM-1115: Energy recovery Description: The concept of energy recovery consists of taking energy that is created as a byproduct of a process, or is left over after a process, and utilizing that energy for something else. Refrigeration cycles are a good place to find this kind of recoverable energy because in order to cool a space, heat must be removed from the space and deposited somewhere else. That removed heat can sometimes be used for another purpose, depending on the system layouts and temperatures involved. We think that the walk-in coolers and freezers in the HUB kitchen area present an opportunity for energy recovery. The condensers of these units reject heat into the environment this heat could be used to meet some of the need for domestic hot water in the building. Applicable Equipment / Buildings: HUB walk-in coolers and freezers. O&M Impact: General heat pump maintenance. Expected Life of ECM: Twenty (20) years. Staff Training Requirements: Heat pump maintenance and relationship with secondary heat source. Recommended M&V Method: None Rebates / Incentives Available: Custom rebates available through PPL s E-power Program, if pursued.

ECM-1116: Cooler energy miser Description: Display coolers consume a lot of energy. While it is important to keep contents cold, most units are designed to provide a level of cooling for a worst case scenario doors opening and closing many times per hour. In reality, during periods of low usage, significant setback is possible without jeopardizing the safety of consumers. Installing a device called an energy miser, which detects the presence of customers (or, as it were, a lack of customers during slow periods), will allow the cooler to reduce the number of cycles it runs when not in heavy use. This will cut energy costs and contribute to a longer useful lifespan by reducing wear and tear. Applicable Equipment / Buildings: HUB display coolers. O&M Impact: Reduce run hours will extend life of compressors. Expected Life of ECM: This type of sensor has an average life cycle of fifteen (15) years. Staff Training Requirements: Sensor operation and control metholodology. Recommended M&V Method: Timers can be installed to monitor run hours to verify performance after sensor installation.

ECM-1120: Tie into main chilled water loop Description: When a campus already has a wide distribution system for chilled water (CHW) from a central location, it makes sense to utilize that loop for as many end uses as possible. It would be advisable to connect a building that currently uses its own chiller into this system to enjoy the benefits of centralization. In the HUB basement, it appears that piping for the central plant loop and the HUB dedicated chiller are in the same room (with AHU-14) so making this switch should be relatively straightforward. Applicable Equipment / Buildings: HUB chilled water loops. O&M Impact: Seasonal switchover required. Expected Life of ECM: Permanent.

ECM-1122: Control of exhaust fans - bathroom Description: Currently the exhaust fans seem to be controlled inefficiently. Instead of having them run constantly, it is recommended that there is control of their operation with time clocks so that they run only while buildings are open, or occupancy sensors which would turn them on only when the bathroom is in use. Occupancy sensor control for the bathroom exhaust fans in the HUB is also suggested. Applicable Equipment / Buildings: HUB bathroom exhaust fan.

ECM-1127: Upgrade lighting - corridor Description: It appears there remains some outdated lighting still remaining in the building. We recommend the replacement of these with newer, more efficient models which use substantially less energy. The main culprit in these cases is usually the T-12 type fluorescent lamp. This was the industry standard in the recent past, but has been superseded by better technology today particularly T-8 and T-5 fluorescents. These offer improved efficiency without the increase in price to cutting-edge lighting such as LEDs. The corridor lighting in the basement is still T-12, and should be upgraded to the more efficient T-8 or T-5 models. Applicable Equipment / Buildings: HUB basement corridor lighting O&M Impact: Reduced re-lamping. Expected Life of ECM: Lighting fixtures have an average life cycle of twenty (20) years.

ECM-1135: Retrocommissioning (RCx) of HVAC Systems Description: Retrocommissioning (RCx) is a process of testing and measurement to verify that systems are still meeting their design intent. As years pass, even finely-tuned systems can slowly drift away from ideal conditions and it becomes harder for them to hit their target temperatures, airflows, and other setpoints. RCx acts as a tune-up, identifying where weaknesses and non-functionalities have developed and allows recommendations to be made that will improve system performance. The savings below are estimates based on our experience and independent studies of retrocommissioning. The costs include the commissioning itself, and also an estimate for remediation of problems found. Actual results will vary depending on what issues the process finds. Applicable Equipment / Buildings: All HVAC and lighting control systems in HUB. O&M Impact: RCx process will lead to improved system operation and a reduction in College staff O&M for troubleshooting issues. Expected Life of ECM: We recommend that systems be commissioned every 3-5 years. Staff Training Requirements: Staff training should occur for any changes to sequences of operation that are implemented to improve system performance as outlined in RCx process. Recommended M&V Method: Verify performance of building steam and chilled water meter and provide monthly reporting before and after Rx process. Rebates / Incentives Available: This ECM may be eligible for a custom rebate from PPL E- power Program if pursued.

PPL Electric Utilities Corporation ( PPL ) is offering financial incentives under the PPL E-power Program to facilitate the implementation of cost-effective energy-efficient measures for commercial, industrial, governmental, institutional, and non-profit customers. Completed applications will be reviewed in the order received. Applicants who submit incomplete applications will be notified of deficiencies upon review of the application, which will be held separately until all requested information is received. Applicants are encouraged to call 1-866-432-5501 if they have any questions about documentation requirements. Funds are limited and subject to availability. The Program and/or its individual components may be extended, modified (including changing incentive levels) or terminated without prior notice. Program Effective Dates The current Program cycle runs from July 1, 2009 through May 31, 2013. The PPL E-power Program and incentives are offered under Act 129 and are subject to change. See the E-power website at www.pplelectric.com/e-power for Program information. Program and Project Eligibility The PPL E-power incentives are available for the energy-efficient measures listed in the worksheets attached to the application. All customers who receive their electricity via the PPL distribution network are eligible to apply for these incentives, regardless of the retail electric supplier from which the customer has chosen to purchase electricity. Both small and large multi-family projects also are eligible for incentives under this Program and must provide their master meter account information. Many projects involving energy savings may be eligible. Incentives are available for both Prescriptive and Custom Measures. TERMS AND CONDITIONS PPL Electric Utilities E-power Incentives Prescriptive Measures are energy-efficiency measures with pre-determined savings and incentive levels. These measures are listed in the Lighting, HVAC, Refrigeration, and Motors and Drives worksheets of the application. Custom Measures are those energy-efficiency measures not covered by any other E-power Program, rebate, or incentive. Accordingly, projects to implement Custom Measures are considered Custom Incentive Projects. Those Projects must be approved by PPL in advance. Incentives are determined on a case-by-case basis, and are paid per unit of energy (kwh) saved (up to $500,000 per site or $2 million per parent company). Custom projects may not result in an increase in summer peak demand usage. Custom Incentive Projects must be cost-effective according to PPL calculations. Projects not eligible to be treated as Custom Incentive Projects include those that: Receive a rebate/incentive through any other energy efficiency program offered by PPL. Produce an electric energy reduction through substitution of another energy source for electricity. Merely terminate existing processes, facilities, or operations; or simple control adjustments that do not involve external costs. Relocate existing processes, facilities, or operations out of PPL service territory. Are required by local, state or federal law; building or other codes; or are standard industry practices. Installation for all Customer Measures must be at the customer s facility and provide 100% of the energy benefits as stated in the application for a period of five years or for the life of the product, whichever is less. Custom Incentive Project Payment Limits Custom Incentives are capped at $500,000 per customer site per year, or $2 million per parent company per year for customers with multiple sites. Technical Study Reimbursements are capped at $50,000 or 100% of the eligible study cost, whichever is less. Technical Study Reimbursement calculations are specific to the type of study and can be found on Page 20. Custom Incentive Project payments cannot exceed 50% of the customer s total external, out-of-pocket costs for the project. Customer internal labor costs cannot be included in calculating implementation costs as they are sunk cost and not incremental costs associated with the custom incentive project. Rev 08/03/12 Page 4
TERMS AND CONDITIONS (cont'd) Application Review Process Pre-approval applications are highly recommended for all projects and are required for Retrofit Lighting Projects, Custom Incentive Projects and Technical Study Reimbursement Applications. Following review of the pre-approval application, which must include all relevant documentation, PPL will respond with a funds reservation letter if the project is eligible. The funds reservation letter is not a guarantee of an exact dollar amount, but serves as approval for project acceptance. Invoices for all associated work must be provided. The project invoice must provide sufficient detail to separate the project cost from the cost of other services such as repairs and building code compliance. PPL reserves the right to request additional supporting documentation necessary to ensure measure eligibility and verify that the expected energy savings will occur. Requested information may include, but is not limited to: equipment purchase dates, installation dates, proof that the equipment is operational, manufacturer specifications, warranty information, and proof of customer co-payment. PPL will make every effort to maintain the confidentiality of customer information except when such information must be provided to the Pennsylvania Public Utility Commission (PUC) and its contractors, as well as contractors engaged by PPL to perform measurement and evaluation. Inspections and/or PUC s Statewide Program Evaluation PPL, its agents, Program Evaluation Contractor, and/or the PUC statewide program evaluator have the right to audit or inspect all projects to verify the accuracy of project documentation as well as compliance with these terms and conditions and the Program rules. This may include pre-installation and/or postinstallation inspections, detailed lighting layout descriptions, metering, data collection, interviews, and utility bill data analyses. By submitting a completed application, the customer agrees to allow access by the entities listed above to project documents and the facility where the measures were installed for a period of five years after receipt of incentive payment from PPL. Tax Liability Incentives may be taxable for most taxpayers. If the incentive is more than $600, it will be reported to the IRS and the customer will be provided with an IRS form 1099, unless the customer is exempt. PPL is not responsible for any tax liability that may be imposed on any customer as a result of the payment of Program incentives. All customers must supply their Federal Taxpayer ID Number to PPL in order to receive a Program incentive. Please consult with your tax professional for information on the tax treatment of the incentives. Warranties/ No Endorsement and Limitation of Liability PPL does not endorse, support or recommend any particular manufacturer, contractor, supplier, product, measure, or system design in connection with this Program. PPL does not guarantee the specific level of energy savings with respect to any product, system design or energy efficiency measure. y g ( ) PPL makes no representations and provides no warranty or guarantee with respect to: (a) design, manufacture, construction, safety performance, or effectiveness of newly installed equipment or (b) the work performed by any contractor with respect to the design, manufacture, or installation of any measures in connection with this Program, including any warranties of merchantability or fitness for a particular purpose. By virtue of participating in this Program, the customer agrees to waive any and all claims or damages against PPL except the receipt of any applicable Program incentives. Customer agrees that, except with respect to any applicable Third Party Payment Release Authorization, PPL shall have no obligations to any third party arising under or related to the Program. The customer and its contractor(s) shall be solely responsible for (i) the construction, installation, maintenance, and/or operation of the measures, and (ii) any liability or claims arising under or related thereto. The Customer and its contractor(s), and not PPL, are responsible for (a) the installation of the measure in accordance with any and all laws, standards and codes, and (b) disposing of any equipment and materials according to local and state code requirements.

NEW CONSTRUCTION LIGHTING REBATE WORKSHEET Lighting Power Density Method Under the Lighting Power Density Approach, the lighting power installed is compared with the lighting power allowed by code. Rebates are available for systems where the installed lighting power density is lower than the code level by at least 5%. Savings are based on the Lighting power Density (LPD) calculated on a watts per square foot basis. Baseline lighting power density is based on ASHRAE 90.1-2007. Either the "Space-by-Space or "Building Area" method may be used to calculate the LPD for the purpose of the incentive. The rebate for the lighting performance based approach is $0.35 per watt reduction in connected load below the ASHRAE 90.1-2007 standard. The minimum lighting power density used to calculate the rebate shall be no less than 5% below the ASHRAE 90.1-2007 value. Required Documentation: 1) PPL Electric Utilities E-power New Construction Lighting Rebate Worksheet (please contact us at 1-866-432-5501 for the most current version), or COMcheck Interior Lighting Report or equivalent analysis demonstrating space-by-space or building area calculations. 2) Final electrical plan sheets showing lighting fixture layout, or lighting fixture schedule sheet including fixture counts. Requested Documentation: 1) Manufacturer's specification sheets showing model number and rated fixture wattage. This LPD table only includes incentives for lighting system efficiency and does not include the capability to enter time, occupancy, daylighting or other controls that may be part of a lighting renovation project. This is because many controls are required by code for new construction and are therefore not eligible for incentives. Lighting controls that are not required by code may be applied for as a Custom project by completing the PA Lighting Form (PA TRM Appendix C) for the fixtures that include the qualifying controls, and applying for a custom project.

Submittal Requirements for Custom Projects 1. Submit Custom Incentive Measure Worksheet with a detailed description of the project, commissioning plan, measurement plan (if applicable), and calculation of savings estimate. THE SUBMITTAL MUST BE APPROVED TO BE CONSIDERED FOR AN INCENTIVE. 2. Install Measures, commission project, and have savings verified. 3. Submit final application with required project documentation. 4. Large Commercial and Industrial projects will be placed on a waitlist as of June 1, 2011. Instructions for Energy Savings Calculations for Custom Projects Custom Project Incentives are based on first year kwh savings that result from efficiency improvements for the first 12 months following installation. The peak demand savings should also be estimated. The peak period is defined by the Pennsylvania Public Utility Commission as the 100 hours of highest demand between June 8 and September 10 and between 12:00 and 20:00 hours. If a measure is covered under the Efficient Equipment rebates (prescriptive Measures) and does not qualify for the prescriptive rebate, it can not be applied for as a custom project. Energy Savings Calculations Provide calculations documenting the predicted energy consumption of the existing (or baseline) and proposed system using appropriate analytical tools and clearly stated assumptions. All analysis should be provided in electronic format. All assumptions such as operating hours, efficiencies, existing and proposed equipment operational details must be presented. Engineering algorithms and procedures from recognized technical organizations such as ASHRAE, SMACNA, ANSI, etc. must be used. Use rated performance factors tested under accepted procedures specified by recognized rating agencies such as AHRI, ANSI, ASTM, etc. Provide an explanation when equipment performance rating conditions vary from standard conditions. In support of the calculations, extensive documentation must be provided that provides the basis for the savings estimates. The documentation must provide information on the equipment operating schedule, daily and seasonal load profile, and baseline AND energy efficient equipment performance at the operating loads. Typical documentation for custom projects often includes but is not limited to: CUSTOM INCENTIVE PROJECT SPECIFICATIONS All Custom Incentive Projects require a pre-approval application. Baseline/existing and proposed equipment make and model number including operating voltage and rated full load amps. Existing equipment condition and age Engineering or architectural drawings and equipment schedule sheets Component specification sheets that include part load efficiency or performance factors Spreadsheet calculations or input/output files and results from system modeling or other engineering analysis using accepted engineering algorithms and practices Log sheets, trend logs from a building management system, or other operating documentation that are often necessary to document operating hours and equipment loading, and used as a basis for the calculations (in some cases, short term monitoring may be required to document the load profile) Control sequence of operations that are necessary where controls play a part in the savings equation Additional documentation, other than that described in the application, may be required for program participation. Projects may also require pre- and post-project sub metering, or monitoring of loads and/or power input as part of another measurement and verification activity to demonstrate the actual energy savings. Baseline for Custom Analysis Where equipment is replaced prior to the end of its rated service life in order to achieve energy savings, the existing equipment performance may be used as the baseline in the energy savings calculations. Where equipment is replaced due to failure, or when it is determined to be at or near the end of its rated service life or for other reasons (such as obsolescence or a need for more capacity), the baseline performance used in the savings calculation should be either the minimum performance that would be required by code for that equipment type and application (where a code applies) or the performance of the equipment that would have been selected as the customer's "standard practice" when a code does not apply. Commissioning and Measurement Plan The purpose of the Commissioning and Measurement Plan document is to identify the process for each of the projects to ensure proper quantitative demonstration of performance.
