BrHEAThe Evaluation

Our BrHEAThe Installs


Two of the greatest challenges in rural housing are high energy costs and poor ventilation. In an effort to address these issues CCHRC developed the BrHEAThe system in 2011. BrHEAThe combines heating and ventilation into one distribution system to provide fresh air and space heating to homes.  Since development, it has been installed in homes in Anaktuvuk Pass, Fairbanks, Galena, Buckland, Point Lay, Brevig Mission, Minto, Bethel, and Tanana. This project documents the history of BrHEAThe from 2011 to the present, including design changes and user experiences. It also evaluates the performance of the BrHEAThe system at the University of Alaska Fairbanks over the winter of 2017-2018.

Energy Recovery Ventilators (ERVs) in Cold Climates Energy Recovery Ventilators (ERVs) are whole house ventilation systems that exchange stale indoor air with fresh outside air, recovering both heat and moisture from the indoor air to save energy. They have the potential to improve indoor air quality in a cold dry climate like Interior Alaska.
