  2. CT EEB Evaluation Administrator PROGRESS & NEXT ITEMS IN EVALUATION COMMITTEE SERA Accomplished 22-24 Evaluation Plan Research Area Data / PO Tracking Legislative Report PSD memo 12/1 cohort Onboarding Current Next Studies for 2022 PSD DEEP COA Ongoing studies 2022 Studies Eval Plan update

  3. CT EEB Evaluation Administrator PROGRESS & NEXT ITEMS IN EVALUATION COMMITTEE SERA COA PSD Input 3-Condensing gas equipment (July) 7- Data dictionary (Sept) 8-Commercial Verification (July) 9-Pay for Performance (Aug) 13-Res All-Electric study needed 25-Tracking data request (July, ongoing) 13 studies or topic studies finalizing PSD process & meetings

  4. CT EEB Evaluation Administrator SERA PSD PROCESS FROM ROADMAP Meetings with utilities / EA Studies completed 5/15 (12/1) Utility memo 6 weeks EA Draft Redline Final PSD 11/1 Response 4 weeks Issues to EC

  5. CT EEB Evaluation Administrator SERA PROGRAM SAVINGS DOCUMENT (PSD) UPDATE Updates based on: Measure specific PSD update studies under X1931 Program-based evaluation studies completed since last update Updates include: Parameter updates in individual measure sections Values for Appendix such as realization rates (RR) and net to gross (NTG) ratios for multiple measures Format update (by utilities) 5

  6. CT EEB Evaluation Administrator SERA PARAMETER UPDATE EXAMPLES PSD Update Research (X1931) Commercial Refrigeration system efficiency (X1931-5): Average seasonal refrigeration efficiency used in several refrigeration measure calculations Commercial Lighting Controls (X1931-4): Energy savings factors (% of annual consumption) developed for various lighting control systems 6

  7. CT EEB Evaluation Administrator SERA EVALUATION STUDY EXAMPLES REALIZATION RATES Gross realization rates (% of claimed savings) Home Energy Solutions (HES) and HES-IE (R1938B) Net realization rates (free-ridership and spillover) Commercial Midstream HVAC and Water Heating (C1902A) Commercial Midstream Foodservice and Laboratory(C1902A) Home Energy Solutions (HES) and HES-IE(R1938A) Realization Rates applied at the Program and Measure Group level 7

  8. CT EEB Evaluation Administrator SERA EVALUATION STUDY EXAMPLES OTHER PSD APPENDIX VALUE UPDATES Heat pump and heat pump water heater study R1965/R2027 presented in residential committee Measure Life Residential (X2001A) EUL & RUL values Non-Energy Impacts (NEI) (X1942A) Non-Energy Impact (for LI) Reduced Arrearage Carrying Cost Reduced Bad Debt Write-Off Fewer shutoffs & reconnects Avoided Reconnect Fees Statewide $0.41 $3.31 $0.00 $0.00 Perspective Utility Utility Utility Participant Energy Conscious Blueprint (ECB) Baseline Study (C1902B) Measure Life (yrs) Air Source Heat Pump Ductless Heat Pump Heat Pump Water Heater Central Air Conditioner Gas Furnace Insulation New Estimate Old PSD 20 17 15 25 28 38 18 18 13 18 20 25 8

  9. CT EEB Evaluation Administrator C1902B ENERGY CONSCIOUS BLUEPRINT (ECB) CODE COMPLIANCE AND BASELINE STUDY SERA Sample of non-participant commercial true new construction 85% - Overall code compliance rate Consistent with findings in other states Installed equipment more efficient than code Lighting (46% more efficient!) Gas heating and water heating Exceeded code baseline in all equipment types and capacity bins. Condensing equipment dominant except steam boilers Unitary cooling equipment and heat pumps Updates to baseline cooling (SEER) and heating (HSPF) efficiency values recommended. 9

  10. CT EEB Evaluation Administrator SERA C1902B ECB CODE COMPLIANCE AND BASELINE STUDY Installed equipment about equal to code Electric chillers Installed equipment less efficient than code Building envelope (insulation and windows) 57% Compliance rate Trade-offs allowed under whole building performance approach 10

  11. CT EEB Evaluation Administrator SERA PREPARING FOR NEXT STUDIES Study Residential Commercial Cross-Cutting Heat Pump New Construction NTG & Code Compliance Impact Oil Savings Methods Impact & Process (BES / O&M / RCx) Heat Pump & Electrification Agriculture Market & Baseline HP & Electrification Shift from EE to GHG Goals & Metrics at State Level Next 2022-24 Evaluation Plan Project List by Evaluation Type Share Share of Budget 23% 26% of Evaluation Type Baseline Impact or Impact/Process Process PSD Topics Total # of Studies 9 10 5 4 17 45 # Budget 34% 26% 40% 100% Residential Commercial Cross-cutting 15 8 22 45 9% 5% 37% 100% Total 11
