Garage Wall Analysis

Project Page

Roughly half the homes in Fairbanks and Anchorage have attached garages, and the average garage is filled with vehicle exhaust, combustion heating appliance exhaust, and VOCs. In Alaska, the current building technique for is to build an exterior wall between the home and garage and seal it with an air/vapor barrier, such as 6 mil polyethylene. This study will establish whether this technique is effective at mimizing air exchange between the garage and home interior.


Research staff will develop a testing protocol and analyze 8-10 homes with attached garages. Results and recommendations will be published in a report that can inform the AKwarm energy rating software. We’ll also publish a snapshot aimed at homeowners on the effects of attached garages on indoor air quality and methods to prevent pollutants from entering the living space.


BrHEAThe with Air Source Heat Pump CCHRC is testing how an air source heat pump can be integrated into a heating and ventilation system in high efficiency homes.
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.
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.
