Executive Summary
Cornell research finds NYC heat pump retrofits kept residents comfortable while cutting heating energy use and guiding Queens public housing upgrades
- Cornell studied a five-story, 10-unit NYC building over three years after a fuel oil steam boiler was replaced with electric heat pumps
- Residents reported equal or better comfort in all seasons and liked room-by-room temperature control
- The retrofit removed old radiators, reducing noise, wasted space, and burn risk from hot surfaces
- Adding roof insulation cut total heat consumption by 25 to 34 percent
- Peak heating power needs fell by more than 10 percent after the insulation upgrade
- Researchers used 73 temperature sensors, power meters, surveys, and interviews to track performance and lived experience
- The findings helped lead to a NYCHA heat pump installation project in Queens public housing
Quick Facts
