This project tested new technologies with standard weatherization practices to reduce HVAC energy use in a public housing authority complex by up to 50 percent.


This pilot is a carryover project from the Illinois Department of Commerce and Economic Opportunity’s research and development initiative. The goal was to test low-capacity furnaces and cold climate heat pumps with standard weatherization practices in seven units in Rockford Housing Authority residential properties. Modeling suggested these measures could reduce total energy use by over 50 percent. Franklin Energy and the Gas Technology Institute led the testing of the ability of these newer technologies to deliver efficient comfort and recorded installation costs and experience.


The pilot’s final report was delivered July 30, 2019. The project demonstrated deep savings through the combination of retrofit strategies implemented, though it was difficult to separate the combinatorial effects of some of the measures.
