BrHEAThe Evaluation

 

Rural Alaska faces many housing challenges, including high energy costs and poor ventilation. In an effort to address these issues CCHRC developed the BrHEAThe system in 2011. BrHEAThe is a combined heating and ventilation system which uses one distribution system to provide fresh air and space heating to high-performance homes in cold climates.  Since the system’s development, it has been installed in homes in Anaktuvuk Pass, Fairbanks, Galena, Buckland, Point Lay, Brevig Mission, Minto, Bethel, and Tanana. This project will document the history of BrHEAThe from 2011 to the present, capturing design changes and user feedback. It will also evaluate the performance of the BrHEAThe system in place 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.
Kenai Indoor Air Quality Study This project examined the most common causes of indoor air quality problems in Southcentral Alaska by monitoring 100 homes for carbon monoxide, carbon dioxide, temperature, relative humidity, and radon.
Mold Survey A survey of mold problems in Alaska Native housing looked at 73 regional or village housing authorities in Alaska and documented over 1700 apartments or homes with some degree of mold problem.
Southcentral Ventilation Study This study monitored nine houses in Anchorage to assess the effectiveness of their ventilation system and compliance with the Alaska Building Energy Efficiency Standard ventilation requirements.
Remediation of Smoke Particles in Fairbanks Homes In the summer of 2004, this project was initiated in response to and in
