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.

Projects

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.
Garage Wall Analysis CCHRC is looking at attached garages to see if they adequately prevent pollutants from entering the house.
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.
