Air Source Heat Pumps Kyle Svendsen & Stephan Wollenburg Agenda - PowerPoint PPT Presentation

Air Source Heat Pumps Kyle Svendsen & Stephan Wollenburg

Agenda  Heat Pump Overview  Incentive Levels  Implementation Considerations 2

Heat Pump Overview  New for 2019-2021 – ability to claim savings from heating fuel displacement  Evaluation feedback – customers don’t operate heat pumps in a way that maximizes heating savings  Solution – integrated controls, which automate dispatch of multiple HVAC systems based on outdoor temp and HP performance 3

Setting Incentive Levels  Determinants of incentive:  Incentive level roughly proportional to benefits  Specific to heating fuel  Ducted vs. non-ducted system  Inclusion of integrated controls 4

Customer Rebates Equipment type Existing fuel Requires Rebate amount integrated controls? Central A/C Any fuel No $50 per ton Ducted heat pump Any fuel No $350 per ton Non-ducted heat Any fuel no $150 per ton pump Ducted heat pump Oil or propane Yes $1,000 per ton Non-ducted heat Oil or propane Yes $1,600 per ton pump Ducted or non- Electric No $1,000 per ton ducted heat pump 5

Customer Rebates and Requirements Central AC/HP Equipment 6

Customer Rebates and Requirements Mini-Split Heat Pump (MSHP) equipment 7

Implementation Considerations  Availability of high-quality contractors  Customer education during the HEA  Customer education about operation  Availability of integrated controls  Elimination of CEC incentives  Calculator 8

Upcoming Passive House Offering  From the 2019-2021 Three Year Energy Efficiency Plan:  Passive House: offering training, technical support, and incentives for evolved design approach that focuses on super- efficient shell or building envelope design and optimized energy systems(pg.10)  Passive House: Program Administrators will focus on developing targeted training, technical support and incentives to promote Passive House building knowledge and investments that can most effectively promote adoption of the Passive House model. Early work will focus on promotion of Passive House for multi- unit and mixed-use buildings. The residential team will work closely with the commercial team’s New Construction Programs.
