3 Appendix A-1 DEER Meaure Databae Update Meaure content, modeling method, model input parameter, and databae format change (Verion 4.00 firt releae in November 2011) Thi document lat updated 8 November 2011 Verion 4.00 of the DEER meaure databae i the update to the mid-december DEER 2008 releae for Energy Efficiency Planning/Reporting (DEER v2.05). It wa created with a new verion of the DEER meaure analyi oftware (MAS). The new MAS tool include a number of change and addition to the previou verion that reult in an improved and expanded DEER meaure databae. The databae tructure and the databae viewing tool, MISer, have alo been updated for thi databae releae. Change to the MAS tool were made to either fix imulation error or to improve the proceing of hourly imulation data for the determination of demand impact. In addition, the MAS tool wa expanded to include additional meaure and additional meaure bae cae that were requeted by the utilitie.

5 Databae for Energy Efficiency Reource: 2011 Update Change to the MAS tool The change decribed here are typically due to error dicovered in the previou MAS tool. Some of the error were imply incorrect building prototype pecification, uch a an incorrect chedule or an inappropriate equipment ize. Other fixe were made in order to make the calculation of demand impact more robut. Large Office primary lighting chedule The primary lighting chedule aociated with linear fluorecent fixture had been (incorrectly) et to the econdary chedule aociated with CFL fixture. The reult wa that the linear fluorecent fixture were on more hour than intended, but with a decreaed coincident demand. The end-ue demand impact increaed by 14% due to thi change while the annual electric end-ue impact decreaed by 10%. The table under the next heading provide the complete liting of lighting operating hour by building type and lighting technology type. Nonreidential indoor lighting operating hour and coincident demand factor All lighting UES value are now baed on a conitent et of lighting operating hour and coincident demand factor (CDF) for the entire building. Whole building operating hour and CDF had previouly been provided by activity area within each DEER building type. The operating hour and CDF provided in the table below are exact value, calculated from the energy imulation reult uing the following relationhip: Operating Hour = Whole Building kwh Lighting Saving Whole Building Connected Lighting kw Reduction The 2008 DEER update documentation included a table of operating hour by activity area within each DEER building type. Thee value were an approximation of operating hour baed on hand calculation of each daily profile to an entire year and were not accurate for ome building type. Additionally the table in the 2008 DEER update documentation did not include operating hour for the entire building. DEER v4.00 require the following table a well a the complete table of CDF included in the appendix to be ued for calculating lighting UES value for DEER building type. Itron, Inc. A-3 Appendix A-1

Refer to the appendix for complete lit of CDF Boiler Sizing The izing method ued for the HVAC boiler reulted in boiler over-ized by % in the older vintage building. The performance of thee boiler operating at low partload caued an over-tatement of the heating energy required to compenate for reduced internal load (uch a aociated with indoor lighting meaure). Hot Water Storage Heater Sizing The ize of the commercial hot water torage heater wa increaed by 25% to account for lower main water temperature in the winter month. In ome building type and in ome climate zone, the demand for water heating exceeded the pecified capacity for long period of time. Packaged HVAC pecification The ingle-phae and three-phae ditinction for SEER-rated packaged HVAC equipment (SEER 12, 13 and 14) ha been eliminated. There are till entrie in the Itron, Inc. A-5 Appendix A-1

8 Databae for Energy Efficiency Reource: 2011 Update databae for three-phae unit, but their performance and energy impact reult are the ame a for the unit that do not pecify the phae ditinction. Reviion to the CEE tier 1, 2 and 3 efficiency level have affected the EER rating of three packaged HVAC meaure. The 10 EER unit in the ize range from kbtu/hr wa changed to a 9.8 EER rated unit. In the ize range greater than 760 kbtu/hr, the 9.7 and 10 EER unit were changed to 9.5 and 9.7 EER, repectively. Oldet building vintage HVAC ytem performance Analyi of CEUS data indicate that many older vintage building have updated HVAC ytem and that thee older building are not well repreented by a contant volume HVAC ytem, a wa aumed for the oldet vintage DEER prototype. Built-up HVAC ytem in the oldet vintage building are now modeled a a combination of contant volume and variable volume ytem, repreented by an variable air volume HVAC ytem with a high minimum flow rate (60% minimum flow). Economizer et point The control for the economizer have been changed in climate zone CZ01, CZ03 and CZ05. In thee climate zone, tandard control etting allowed the economizer to be ued during the peak cooling period, cauing a large peak latent cooling load. Though compliant with the Title-24 ACM pecification, it i unlikely that an economizer would be utilized in a way that increae the peak demand. The economizer et point temperature, above which the outide air i forced to it minimum flow rate, wa lowered to 70 F from 75 F in thee climate zone. Thi change reult in more appropriate (i.e. maller) deign chiller ize in thee climate zone, epecially in the older vintage building. DOE2.2 bug fixe Thee change to the meaure analyi oftware tool were prompted by an update to the DOE2.2 imulation engine that i ued in the DEER MAS tool. The following fixe were identified a having ome impact on the DEER meaure reult; there may be other bug fixe included in the update of the DOE2.2 imulation engine that do not affect the DEER reult. Fix that affect the outide air volume aociated with duct leakage: thi mainly impact the mobile home duct meaure but ha a mall effect on the inglefamily and multi-family prototype a well. DOE2.2 wa previouly over accounting for outide make-up air aociated with duct loe to unconditioned pace (in both bae and meaure cae). Non-commercial building were not impacted by thi fix. Fix regarding default minimum heating flow rate. In ome cae, the default zone minimum heating flow rate did not default to the ytem minimum heating flow rate a wa intended. The impact of thi fix on the DEER reult i minor. Fix that correct an error with the calculation of the heat load due to lighting fixture under pecific circumtance of zoning and lighting ytem configuration. All of the reult in the Lighting Workbook are baed on imulation that include thi DOE2.2 ource code correction. T12 linear fluorecent baeline fixture Input power for T12 linear fluorecent baeline fixture were updated to reflect USDOE ballat efficacy requirement enacted in Itron, Inc. A-6 Appendix A-1

9 Databae for Energy Efficiency Reource: 2011 Update Minimum efficiency requirement for magnetic ballat were adopted a part of EPACT in Ballat covered by thee tandard are often called Energy Efficient or ES magnetic ballat. Thee minimum efficiency requirement were updated again in The new requirement eentially prohibited the incluion of ES magnetic ballat in any new fixture. However, the tandard did allow the hipment of ES magnetic ballat for repair or replacement purpoe. In 2010 EPACT prohibited the manufacture or import for ale of any T12 magnetic ballat. Mot importantly, EPACT 1990 required ES magnetic ballat for all nonreidential application. Pre-EPACT (pre-1990) fixture that were intalled with tandard magnetic ballat would need to have urvived without any ballat replacement for twenty three year by Ballat replacement would have utilized either an ES ballat in the 1990 or a hybrid or electronic ballat in the period and ince 2010 an electronic ballat. During thi ame time period (epecially pot 1990 ) the tandard lamp/ballat and fixture retrofit have become T8 lamp with electronic ballat and the price and availability of electronic ballat compatible with the T12 lamp ha allowed them to become the normal repair choice. For thee reaon, baeline wattage of fixture in the DEER lighting fixture table that include pre-epact magnetic ballat have been revied to aume ES magnetic ballat. The table provide a ample of thee fixture power reviion for 4 and 8 foot 2-lamp fixture.

Thi change impact refrigerator imulated in the houe a well a thoe imulated in the unconditioned garage. The pecified value of 90 F correpond to the DOE rating condition for refrigerator, but for thee imulation, the value mut correpond to the temperature at which the pecified EQUIP-PWR-FT curve return a value of 1.0. Thi correction caue the imulated energy ue of the refrigerator to increae by 17% in conditioned pace and by a much a 22% in unconditioned pace. Peak-Period Demand Iue In order to make reult from tandard energy imulation program (pecifically, equest) conitent with the DEER demand impact reult, the calculation ued by the MAS tool to determine the demand impact wa modified. The baic calculation remain the ame: the demand aving due to an energy efficiency meaure i calculated a the average reduction in energy ue over a defined nine-hour demand period. The previou databae verion ued the moothed hourly impact a the bai for thee calculation while the latet verion ue the non-modified reult from the DOE2 imulation. The difference in the demand value between thee two method i typically quite mall, but occaional large deviation from expected value were oberved. Change to the HVAC control cheme for the affected ytem type were required in order to produce reliable demand reult. Thee change to the HVAC control reulted in very little difference to the annual energy aving, but much more predictable behavior during the peak demand period. The following change were implemented for all appropriate ytem type: Night cycle control etpoint were expanded (max 60 for heating and a minimum of 86 for cooling) o that the number of hour of night-cycling would not change ignificantly between the bae and meaure imulation. Change in the hour of night cycle control would occaionally hift the cooling load by an hour and reult in relatively large difference in the hourly energy ue of the bae and meaure imulation during the demand period. Outide air i turned off during night cycle control; though rare, the induction of ome latent load aociated with the outide air flow during night-cycling could exaperate the night-cycle iue dicued above. Space heating i turned off during the peak cooling period; though rare, the occaional need for pace heating during the cooling eaon in ome climate zone would hift cooling demand by an hour and caue large change in the hourly demand between a bae cae imulation with high lighting load and a meaure cae with low lighting load.

14 Databae for Energy Efficiency Reource: 2011 Update A ingle chiller i ued for non-hvac meaure; thi prevent a tep-function change in demand when the controller witche between one and two chiller. When appropriate, multiple chiller are till ued for the analyi of HVAC meaure. Addition to the DEER databae A number of addition were made to the DEER databae at the requet of the IOU. The following lit ummarize thee new entrie: Non-reidential lighting fixture; over 100 new lighting meaure were added to the databae. Refer to the accompanying preadheet for a decription of all change and addition. Update for Code Baeline Baed on EPACT and 2008 Title 24: For fixture replacement and early retirement meaure that are covered by Title 24 LPD requirement, linear fluorecent fixture code baeline were revied to reflect the typical fixture needed to meet the new maximum intalled lighting power requirement. In general, econd generation T8 lamp and electronic ballat are required. For retrofit meaure, code baeline were revied or added to all four foot and 8 foot linear fluorecent meaure to reflect the July 2012 federal prohibition of manufacture and ale of T12 lamp and magnetic ballat. All code baeline now aume T8 lamp and electronic ballat. A total of 14 hot water and team boiler meaure were added to the non-reidential meaure lit. Clothe waher and dihwaher meaure were added for all reidential building type, including the multi-family apartment building. Reidential multi-family prototype i now included in the databae. All reidential meaure defined for the ingle-family building type have adapted to the multi-family prototype. Additional meaure pecific to the multi-family building type have alo been added, including common water heater meaure and common clothe waher meaure. Reidential and nonreidential high efficiency heat pump meaure are now included in the databae. Thee include reidential heat pump ranging from 13 SEER to 18 SEER and nonreidential heat pump that align with the latet high efficiency tier etablihed by the Conortium for Energy Efficiency (CEE.) Reidential inulation retrofit meaure have been updated from the 2005 reult included in v2.05. All imulation update dicued above have been utilized in developing UES value for thee meaure. In v2.05 ceiling batt inulation meaure were defined with a bae of no inulation and variou meaure level equal to tandard batt inulation level uch a R-11, R-19 and R-30. Thee meaure definition have been revied to add tandard batt inulation level to the typical inulation for a particular home vintage a defined in DEER. Itron, Inc. A-12 Appendix A-1

15 Databae for Energy Efficiency Reource: 2011 Update Agricultural greenhoue retrofit meaure have been updated to reflect reult of impact evaluation work from PG&E Agricultural and Food Proceing Program. The change include the improvement lited below. 1. The meaure may be taken individually, in combination or with baeline that include one of the other meaure (e.g. that addition of a thermal curtain to a greenhoue that already ha IR film on it roofing material.) 2. The EUS value include two heating ytem type, a tandard overhead ga-fired unit heater and a floor level radiant heating ytem (typically team or hot water circulated through piping within the greenhoue.) 3. Revied greenhoue imulation model for greenhoue with overhead heating ytem developed in 2008 for and confirmed by the PG&E Agricultural and Food Proceing Program impact evaluation. Thee model change addreed major iue that affected energy aving aociated with the variou meaure - predominantly prior incorrect temperature tratification aumption. 4. The impact evaluation found that radiant heating ytem will dramatically reduce the aving due to the elimination of temperature tratification within the greenhoue. Stratification increaed energy ue a temperature above the greenhoue are higher, reulting in a larger heating load that would occur if the temperature were uniform. The report note thi a major contributing factor to low realization rate (39% for IR film meaure and 62% for thermal curtain). The meaure update reflect the addition of thi heating ytem type which wa identified a the primary type of heating ytem utilized in California greenhoue. 5. IR film attached to wall and ingle-layer roofing material are included in the databae howing zero aving. Select non-updated reult from DEER2005 retired: Non-updated meaure from the DEER2005 databae that were included in the DEER2008 databae were evaluated for relevancy in the current planning cycle. Meaure that were updated in verion 3.02 or 4.00 were dropped a were meaure that are either no longer relevant or covered by updated IOU workpaper. See the appendix for the tatu of all DEER 2005 meaure include in the previou verion.

Change to the DEER Reult The accumulation of change lited in thi document ha caued a large portion of the DEER energy impact reult to change at leat lightly. Some update have caued pecific reult to change ignificantly, uch a the large office lighting profile fix. Other change, uch a the variou HVAC control and izing iue lited above, have had only a mall effect on the electricity energy and demand reult, but have a profound effect on the econdary natural ga impact. In almot all cae, the heating energy take back aociated with commercial lighting meaure ha decreaed dramatically (on the order of 25 60%). Figure 1 how the large decreae in the negative ga impact for a lighting meaure in the multi-tory retail building prototype. Thi reult i typical of prototype with central plant HVAC ytem and i largely due to change in the control mechanim of the oldet vintage HVAC ytem and the fix to the boiler izing.

46 Appendix A-2 Thi appendix decribe how the building type effective full-load hour (EFLH) and coincident factor (CF) value were developed uing data gathered a part of the Small Commercial Contract Group evaluation (Small Com evaluation). It alo decribe how the activity area ditribution were calculated. EFLH and CF Calculation Setup (applie to both the EFLH and CF calculation) The Small Commercial evaluation involved the intallation of nearly 7,000 lighting logger in over 1,200 commercial building throughout California. Extenive training and QC procedure were applied to the lighting logger intallation, a i documented in the Small Com report. The ON/OFF tranition data from each lighting logger wa proceed into a percent ON per hour format. Each logger wa then extrapolated into an 8760 lighting ue hape, a decribed in the Small Com report. Since ome ite aw multiple logger intalled in the ame activity area, the 8760 ue hape were averaged together to create a ingle 8760 for each activity area at each ite. The number of lamp repreented by each logger wa ued a a weight to create thi ite level activity area hape. The firt tep in calculating the EFLH and CF value for thi DEER update wa the creation of the weekly uage profile. Each ite level activity area 8760 wa collaped to an 8-day ue hape (five weekday, 2 weekend and an eighth day for holiday). Thee ite level activity area 8-day hape were then averaged together to make an 8-day hape for each building type - activity area that wa reported in Small Com. The total number of lamp logged within each activity area at each ite wa ued a a weight to create thee building type - activity area hape. In thi way, we arrived at a percent ON value for each hour (0-23) of each weekday (1-8) at each building type activity area. To explain in ymbol, if we let where HR h,w,b,a be the average hour ON during hour h on weekday w at building type b and activity area a, then we have: HR h,w,b,a = w,a HR,h,w,a w,a where the um are taken over all ite uch that ha building type b and activity area a. Itron, Inc. A-2-1 DEER EFLH and CF Decription

47 DEER EFLH and CF Decription The term w,a repreent the total number of lamp at ite in activity area a. So, in thi cae, w,a would repreent the total number of lamp in activity area a in ite with building type b. The term HR,h,w,a repreent the percent ON in activity area a ite during hour h on weekday w.
