Coupled with the increased savings over time, this could be truly welcome news for homeowners looking to replace their homes.
As a test, the team, called the ARIES Collaborative, built three homes:
- House A built to the HUD standards was equipped with typical electric furnace and split system air conditioner and had climate region typical insulation levels;
- The ENERGY STAR house (House B) had enhanced insulation levels, low-E double paned windows and a conventional split system heat pump; and
- House C was a next-generation design that qualified for Zero Energy Ready Home designation and included a high efficiency, single point, ductless, mini-split heat pump with a transfer fan distribution system in place of the traditional duct system for distribution.
The homes were set together in Alabama so they were exposed to the same weather conditions.
