Scaling Heat Pump Retrofits in Housing with Cost Barriers


Climate Resolve and the U.S. Green Building Council, Los Angeles chapter (USGBC-LA) will capture and analyze data from 15 pilot projects funded by TECH and 30 new heat pump projects. Subsequent analysis will support the development of a GHG calculator (including utility-level grid emission factors, GHG reductions from fuel switching, and potential GHG increases from refrigerant leaks and recharging) that can be used to support green financing products by heat pump retrofit projects. Through this pilot, TECH will gain insights on how to design efficient incentives that leverage and complement third-party financing.

Research Questions:

  • What is the range of greenhouse gas savings from implementing heat pump retrofits as a component of residential electrification?
  • Are these reductions large enough to support green financing for heat pump adoption in housing with cost barriers?

Market Barrier

There is a lack of rigorous data analysis related to the GHG impacts of heat pump retrofit projects, which limits access to green financing for retrofits in housing with cost barriers.

Proposed Solution

1) Produce a key performance indicators (KPI) assessment—including energy savings, cost savings, GHG emission reduction, cost per ton of GHG emission reduction—from the installation of 30 heat pump retrofit projects replacing natural gas, and 2) use the data assessment to develop a GHG calculator.

Theory of Change

Generating data analysis on heat pump retrofits as a component of the KPIs associated with building electrification will attract new sources of green financing to retrofit housing with cost barriers.
