4 Executive Summary Winston-Salem State University Energy Data Management: The University continues to update its established excel spreadsheets for collecting and analyzing all of the monthly energy billing information. Efforts continue to improve the comprehensive program for collecting and analyzing all the monthly facilities usage and cost data. This effort is designed to improve the evaluation of variations and to assist in determining the corrective action required. The data is posted in the Facilities shared data files for review by all in the department. The Key Performance Indicators the University used to measure our energy program demonstrated very minor increases in two areas and a large increase in the third. The performance indicator changes for energy consumption for fiscal year from the previous year are as follows: (a) an increase per square foot of 0.02%, (b) an increase per student credit hour of 0.26%, and (c) an increase per FTE student of 7.82%. The increase in energy use per FTE coincides with a decrease in FTE students of 7.24%. Fiscal year saw an increase of 36 heating degree days over the previous year (which itself had 459 more heating degree days than the prior year). The heating season was cooler than any previous year since the inception of this report accounting for the increased use of natural gas for heating purposes. A break down by energy source for the usage and cost data per square foot for the total campus for fiscal year thru are shown in Appendices 1 thru 8A Energy Supply Management: Most of the University facilities are on the time of day electrical rate schedule, which is the preferred rate at this time. The University continues to evaluate all accounts for the rates providing the greatest savings. Natural gas is the primary energy source for the central steam plant boilers, with number 2 fuel oil as a secondary fuel source. Competitive pricing is solicited each month for natural gas and fuel oil in order to determine which is most economical for the current month fuel source. Energy Use in Facilities: All the facilities have basic control systems and newer facilities have digital computer control systems. Temperature operating ranges have been established for all our buildings and are continually being reviewed. Facilities held several meetings during the year with the maintenance and - 4 -

5 engineering departments to discuss ways to improve building control systems to save energy. HVAC systems, for instance, are being cutback at night when rooms are unoccupied. Energy efficient lamp cross-reference replacement list has been established for operations to use when replacing burned out lamps. HVAC system operational controls are continually being evaluated to provide better control of our existing systems. The University Facilities Department is continuing to develop its conservation awareness program and evaluating new buildings design for energy savings. Buildings with DDC controls have established occupied and unoccupied schedules to reduce the energy consumption. This program has proven to be very effective with minimal building complaints. The University completed a comprehensive steam trap survey of the steam distribution system and buildings on campus. Many malfunctioning traps were identified and targeted for repairs and replacement. The University has embarked on an Energy Saving Performance Contract for ten buildings. We are currently in the investment grade audit phase. All new buildings will comply with the energy and water efficiencies mandated by Senate Bill 668 (SL ) and will be built to, or be certified to LEED Silver standards. Equipment Efficiency: Maintenance programs are in place to insure the most efficient operation of the University boilers. Filter changes, coil cleaning, and inspections are performed on a regular basis to insure proper operation. Energy consumption and costs for individual buildings are maintained in an excel spread sheet for use in recording, charting, and analyzing building efficiencies. The main heating plant boilers are on a yearly tune up program every summer. Facilities have an ongoing program to check and repair steam traps in an effort to reduce energy and water waste. The University s preventative maintenance program continues to prove successful and the program is continually being expanded. We are continuing to improve the steam distribution system. New underground steams lines were installed from K. R. Williams auditorium to the Hall Patterson Building. This project will help to reduce our steam leaks and energy loss. Organization Integration: The Director of Facilities Operations has been assigned the day-to-day responsibility for the energy management program

6 Facilities HVAC technicians and Engineering continue to review the control systems of campus buildings. This review process helps to improve on the understanding of how the building control systems are functioning. This year we plan to improve our campus Energy Conservation and Awareness program through higher student involvement and the Campus Sustainability Committee. The University is improving its awareness programs for students. There was a student driven Green Week last spring with significant student participation in programming and response. Videos have been published on the WSSU website for energy conservation. ( Water Management: Water use, by volume, in FY remains at 20.5% less than in the baseline year. WSSU has met and greatly exceeded the goal of 10% reduction in water consumption in all three key performance indicators. Several malfunction water level controllers in HVAC equipment were identified and repaired. Videos have been published on the WSSU website for reducing water consumption. ( Goals & Measures The primary goal of the Strategic Energy Plan is to reduce our total energy consumption to meet the State target of 123,330 Btu/gsf/yr by The University s Energy Plan will support Senate Bill 668 (SL ). Based on the growth plans of the University, the University will track its progress in meeting the Strategic Energy Plan with the following criteria. Total energy consumption per square foot Total energy consumption per student credit hour Total energy consumption per FTE student Trend graph for these criteria will be plotted each month and reviewed by the Energy Manager. Baseline Energy Use Winston-Salem State University s current energy usage mix in BTUs for FY is 46.3 % power, 55.7% natural gas, and 0% # 2 fuel oil. The university established fiscal year as the baseline for its energy program when the energy usage mix was 44.7 % power, 49.6% natural gas, and 5.7% # 2 fuel oil. Since the baseline year , the University operates its boilers 24 hours a day, 7 days a week, to support the - 6 -

The program is very detailed and is continually being evaluated and improved. A break down by energy source of the usage and cost per square foot for the total campus for fiscal year thru is presented in Appendices 1 thru 24. Planned Actions & Projects Projects: Completed Projects : Underground steam piping replacement from SMH-30 to SMH 30A at the Hall Patterson Building to eliminate steam, energy, and water losses Retro-commissioned portions of the Anderson Center and Thompson Center heating ventilation and air conditioning control systems. Replace lighting Fine Arts second floor. Disconnected drink vending machine lights and some snack machines. Identified and repaired two mechanical systems with cooling tower water level control issues. Planned/Current Projects: Continue to upgrade existing lighting systems that have T12 fluorescent lamps and magnetic ballast with the new energy efficient T8 lamps and electronic ballast on an as needed basis. Install new fluorescent lamps or LED lamps in place of incandescent lamps. Old Nursing roof replacement. Energy Savings Performance contracting on ten campus buildings. We are currently in the investment grade audit phase. Install metering on buildings currently without individual meters. Replace malfunctioning steam traps identified in the Steam Trap Survey

8 Completed Actions: An energy services company, Siemens, has been contracted to perform the investment grade audit phase of energy savings performance contracting. Completed a survey of campus steam traps to determine functionality. Performed building cutbacks during the Christmas break to conserve energy. Planned Actions: Develop a maintenance program for the replacement of motors with premium efficiency motors. Building shutdowns during extended holidays and the summer break. Consolidating resident students to empty one residence hall. Going trayless in all dining facilities. Savings Opportunity Assessment: The University continues to make improvements to its program for collecting and analyzing monthly energy billing information, and compiling a comprehensive database to allow tracking of energy usage for the campus. Facilities Operations has established a committee to evaluate each campus building and establish HVAC control temperature settings for the building. Now it is time to review each adjusted building to ensure settings are working as expected. Facilities Engineering continues to improve the capability to track energy use in each building on campus. Review the energy rate schedules to evaluate the most economical rate schedule for each energy service at the University. Develop a maintenance program for the replacement of motorized equipment, which is subject to be replaced, with premium efficiency motors. Budget: The Facilities Management Department will continue to use its existing budget to focus on no/low cost initiatives to improve the University on-going energy conservation efforts. Some budget has become available for energy related projects. Energy Mandate: Energy and energy management must be recognized as a controllable operating expense where in savings can result in funding being available for other program needs. If the energy management program is to be successful, all members of the Winston-Salem State University Community, Students, Faculty, and Staff, have important roles to play

9 Energy cost reduction must become a vital part of the University Strategic Energy Plan. This plan must support the energy reductions required in Senate Bill 668 (SL ). As integral part of this Energy Strategic Plan the University has established an Energy Mandate for Winston-Salem State University. The University Energy Conservation Mandate is presented in Appendix 25. Appendices: - 9 -

12 Appendix 2 (continued) Fiscal year with Comparison to Baseline year Student enrollment increased significantly from fiscal year The student credit hours for the fiscal year increased by 26.48% and the full time equivalent student increased by 22.96%. The increase in student population has resulted in the University extending the hours of operation of the building facilities. More classes than in past years are being taught at night and on weekends, which has resulted in an increase in total energy consumption on campus. We anticipate this trend to continue in the coming years. The University continues to add to the infrastructures to accommodate the increasing enrollment. In fiscal year the University opened the new Computer Science building consisting of 62,000 square feet of classroom and office space in December The Computer Science building is estimated to have increased the power cost by $25,000, natural gas cost by $14,000, and the water cost by $3100 for a total energy cost increase of $42,100 in fiscal year The chiller was required to run continuously during the winter months because of have to cool the University main computer server room. This situation is in the process of being corrected. In addition to the computer science building, a new central chiller plant was brought on line in late April of The new central chiller plant was operated on a demand basis for the entire fiscal year for the first time. The Chiller Plant with a capacity of 800 tons was estimated to be loaded at 250 tons this year and to have increased the University energy cost by $92,000. In the spring of fiscal , K. R. Williams Auditorium stand-alone chiller was removed and the auditorium was connected to the central chiller plant chill water loop. Projections are the adding of K. R. Williams to the chill water loop will result in energy savings of $10,835 per year. Fiscal year has seen natural gas and fuel oil prices increase substantially. These price increases resulted in an energy cost increase to the University of $55,318. Our Energy conservation efforts have reduced the rise in energy cost. The three criteria we use to track our progress in meeting our Strategic Energy Plan have all reduced for fiscal year Total energy consumption per square decreased by 0.64 %, Total consumption by student credit hour decreased by 16.65%, and Total energy consumption per full time equivalent student decreased by 14.26%. 12

14 Appendix 3 (continued) Fiscal year with Comparison to Baseline fiscal year Student enrollment for a straight second year has increased significantly from the baseline fiscal year. The student credit hours for the baseline fiscal year increased 54.39%, and the full time equivalent student hours increased by 46.51%. Due to the increase in student population, the University continued the extended hours of operation of the building facilities. More nontraditional classes than in past years are being taught, which has resulted in an increase in total energy consumption on campus. We anticipate this trend to continue in the coming years. The University continues to add to the infrastructures to accommodate the increasing enrollment. In fiscal year the University added the new Physical & Life Sciences building consisting of 52,000 square feet of classroom, science laboratory, and office space in November 2004, assumed responsibility of Rams Commons consisting of 193,425 square feet of residence hall space, added Early Childhood consisting of 7,200 square feet of day care space, and added Anderson Center temporary modular units consisting of 11,328 square feet of classroom and office space. The additional square footage is estimated to have increased the power cost by $95,000, natural gas cost by $15,000, for a total energy cost increase of $110,000 in fiscal year During the year the University had two building under renovation (Carolina Hall and Anderson Center A & B Wings) totaling 97,761sq.ft. In the spring of fiscal year , Hauser Hall stand-alone chiller was removed and the building was connected to the central chiller plant chill water loop. WSSU projects that adding Hauser to the chill water loop will result in energy savings of $6, per year. Fiscal year has seen natural gas and fuel oil prices increase substantially. These price increases resulted in a significant energy cost increase to the University. Our energy conservation efforts have partially offset the rise in energy cost. The three criteria we use to track our progress in meeting our Strategic Energy Plan have all reduced for fiscal year from the baseline fiscal year. Total energy consumption per square foot decreased 1.69 %, total consumption by student credit hour decreased 19.55%, and total energy consumption per full time equivalent student decreased by 1.13%. 14

16 Appendix 4 (continued) Winston-Salem State University Fiscal year with Comparison to Baseline fiscal year Student enrollment continues to show increase over the baseline fiscal year. The student credit hours for the fiscal year increased 74.28%, and the full time equivalent student hours increased 66.43%. Due to the increase in student population, the University continued the extended hours of operation of the building facilities. More nontraditional classes, (weekend and evening classes) than in past years are being taught, which has resulted in an increase in total energy consumption on campus. We anticipate this trend to continue in the coming years. The University continues to add to the infrastructures to accommodate the increasing enrollment. In fiscal year the University added the new Student Health building consisting of 11,500 square feet of medical, and office space in September 2005, and Gleason-Hairston Terrace residence hall consisting of 136,582 square feet of residence space. In addition, the Anderson Center and Carolina Hall renovation projects were completed which returned 111,106 square feet of classroom and office space back on line. This additional square footage is estimated to have increased the power cost by $98,000 and natural gas cost by $4,500 for a total energy cost increase of $102,500 in fiscal year Fiscal year has seen natural gas and fuel oil prices increase substantially. These price increases resulted in a significant energy cost increase to the University. Our Energy conservation efforts have partially offset the rise in energy cost. Two of the three criteria we use to track our progress in meeting our Strategic Energy Plan have decreased for fiscal year versus the baseline year. Total energy consumption per square foot increased by 0.87%, total consumption per student credit hour decreased by 18.88%, and total energy consumption per full time equivalent student decreased by 15.06%. 16

The student credit hours for the fiscal year increased 12.86%, and the full time equivalent student hours increased by 13.60%. The increase in student population has resulted in the University extending its hours of operation for the facilities. More classes than in past years are being taught at night and on weekends this trend is anticipated to continue in the coming years. However, the University water usage per square foot has declined 16.38% this year due to the efforts of the facilities department reducing steam leaks, water leaks, and excess water losses thru the HVAC equipment. The University measures for SCH and FTE also declined % and 18.35% respectively. The 2.79% increase in cost is the combination of a 7% rate increase and the 7.24% reduction in usage. 28
