Title: Electrifying Space Heating in Existing Commercial Buildings

Date: Monday, November 02, 2020

Time: 11:30 AM Eastern Standard Time

Duration: 1 hour


Cities and states are increasingly looking at electrification as a policy tool to reduce their greenhouse gas emissions. Research has shown promise in the residential building and transportation sectors. However, comparatively little research had been conducted (so far) in the commercial building sector. Analyzing the commercial sector is complicated due to the wide variety of building types and often complex building heating and cooling systems.

In this webinar, ACEEE will present results from its new study investigating the electrification of commercial buildings HVAC retrofits, including energy and carbon savings, cost-effectiveness, and policy recommendations.

An engineer from Trane will join the webinar to provide a manufacturer’s perspective on the growing use of heat pumps and also some of the challenges. In addition, a UC Davis energy manager will describe how his team is approaching electrifying buildings on campus through the use of heat pumps, energy storage, and geoexchange.
