Kenai Indoor Air Quality Study

Project Page

This project attemps to solve the most common causes of indoor air quality problems in Southcentral Alaska. Project Manager John Davies, working with the contractors, Wisdom and Associates, monitored 100 homes during the 2003-04 winter for carbon monoxide, carbon dioxide, temperature, relative humidity, and radon. Each home underwent a BEES ventilation check, an ultra-fine particle sweep, and a pressure imbalance testing. The draft final report, currently in review, will present data from all the studied homes, an analysis of trends or patterns that led to poor indoor air quality, and recommended solutions.

Projects

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.
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.
