1. Coupling Program Outreach with Energy Studies to Identify Deep Savings Peter Serian, ERS 5/14/2014

2. Agenda The need to couple outreach with energy studies Using outreach to implement low hanging fruit Energy studies for deep saving retrofits How to scale implementation of deep saving retrofits Case studies 3. The Need to Go Deeper Year-over-year utility energy efficiency goals Low hanging fruit largely implemented Success implementing deep saving retrofits by coupling outreach with in-depth energy studies Outreach Program Energy Study Program Deep Savings 4. Program Outreach Strategy Targeted paths Direct customers Market partnerships Program marketing State/Local Federal Design engineers Trade orgs Public agencies Vendors Finance 5. Keys to a Successful Outreach Program Find the path in engage with energy champions. Relationship development Technical support, best practices, measure discovery Identify barriers and connect the dots 6. Outreaching the Limits Breadth of end users, finite depth of technical support Low hanging fruit . . . mostly identified and implemented The need for deep savings retrofits 7. Target End Use for Deep Savings HVAC is the #2 end use for commercial facilities. Target optimized control of HVAC. Based on Center for Building Energy Consumption Survey (CBECS ) data 8. Deep Savings Retrofits Air-side HVAC Water- side HVAC PSNH Energy Audit for Portsmouth Regional Hospital, Portsmouth, NH, 2012 9. Coupling Outreach with Energy Studies Outreach identifies potential; energy studies pursue deep savings. Tailor energy study type to customer needs. Timeline, energy goals, available capital, investment criteria 10. Case Study #1: NYSERDA FlexTech Over 80% of controls measures implemented by year 4 11. Case Study #2: PSNH C&I Retrofit Program Turn off space heating pumps in summer Set back temperatures in unoccupied spaces Optimize supply air temperature reset Install demand control ventilation Shut down RTUs on nights and weekends Predicted savings: 29% Realized savings: 36% Multi-tenant, three-story, 66,000 ft2 commercial facility in NH 12. Summary Program outreach is effective at implementing low hanging fruit and identifying the potential for deeper savings. Next tier of savings is deep savings retrofits. Optimized control of HVAC is the target for commercial facilities. Coupling outreach with an energy study program is the key to identifying, quantifying, and implementing deep savings retrofits. 13.
