Projects

BrHEAThe Evaluation 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.
Designs for Rural Alaska Walls Monitoring CCHRC demonstration homes for efficiency and moisture infiltration several years after construction.
Structural Insulated Panels Structural Insulated Panels (SIPs) are prefabricated building materials used in residential construction in Alaska. This project prepared resources for homeowners who want to learn about SIPs, where they are used in cold climates, and considerations for Alaska.
Safe Effective Affordable Retrofits Testing a new batch of wall systems that can provide affordable retrofit options.
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.
