Garage Wall Analysis

Project Page

Roughly half the homes in Fairbanks and Anchorage have an attached garage. Many garages are filled with exhaust from vehicles and heating appliances as well as VOCs. The current building technique in Alaska is to build an exterior wall between the home and garage sealed with an air/vapor barrier, such as 6 mil polyethylene. This study asks whether this technique is effective at mimizing air exchange between the garage and the rest of the home, keeping dangerous gases out of the living space. 


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.


Little Ventilation Project Looking at ventilation systems that can improve indoor air quality in small homes while limiting energy use.
Bath Fan Installation Best Practices Create standards for installing bath fans based on an evaluation of five Panasonic WhisperGreen units.
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.
