Recent Evaluations

Multi-Family Evaluations Eval Study Process Impact Other Status # Mass Save Multifamily Program Complete  1 Process Evaluation Report (2015) Complete  2 Multifamily Impact Evaluation (2016) Ongoing / Multifamily Program Preliminary   3 Improvement Strategies Results (3/29/17) Census of Multifamily and  4 Ongoing Condos Multifamily Lighting Impact and   5 Program Net-to-Gross Launching Evaluation 15

Evaluation 2: Impact Evaluation Gas realization rate of 86.2% applied to envelope, hot water and HVAC measures “Given the difficulty in observing lighting savings due to its low savings signature, consider other evaluation methods in subsequent studies of this program when predominate [sic] savings is from October 2016 lighting.” 16

Part 1, Evaluation 3: Program Improvement Strategies Preliminary results  Update lighting savings assumptions  HOU in-unit lighting  HOU common areas  In-service rate  Highlighted need for strengthened project reporting and verification procedures March 2017 17

Part 2, Evaluation 3: Program Improvement Strategies, Other Questions How do we expand comprehensiveness?  Shift customer expectations to incorporate additional measures into projects  Reinforce auditor training to identify and complete additional measure types How do we continually improve?  National literature review of best practices  In-depth interviews for program implementation strategies 18

Evaluation 4: Census of Multifamily and Condos  Understand the full population of multifamily and condo properties  Geography  Number of units  Rental status  Delivered fuels  Occupant income  Program participation  Assign premise identities and link to program activity 19

Evaluation 5: Lighting Impact & Net to Gross  Lighting in-service rates will be updated in 2018  Site visits will be conducted to confirm program changes  Net-to-gross analysis 20

Looking Forward

Multi-Family Continuous Improvement Lessons from Evaluation 3, Program Improvement  Changes to lighting installation best practices  Switched to deemed savings for in-unit lamps using hours of use specific to Massachusetts Multi-Family  Discontinued installation of in-unit fixtures  Created new “EISA Exempt” category to more accurately track measure life of lamps  QA/QC processes being changed to “in - process” inspections to better capture pre and post conditions 22
