Evaluating Ventilation Systems & IAQ

Project Page

CCHRC, through a grant from Alaska Housing Finance Corporation, contracted with Alaska Building Science Network (ABSN) to monitor 100 relatively new homes in 3 different climatic regions in Alaska (Anchorage/Matsu, Juneau, and Fairbanks). Monitoring consisted of relative humidity, particulates, and VOC's. The goal of this study was to provide an evaluation of the extent to which various factors, including ventilation strategies, house characteristics and location, and occupant usage affect indoor air quality. ABSN obtained 13 CO data loggers from the Municipality of Anchorage and included Benzene in their testing.


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.
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.
