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.
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.
In the summer of 2004, this project was initiated in response to and in the midst of the heavy smoke in the Fairbanks area due to wildfires. Bill Reynolds of Solutions and Cathy Cahill of the University of Alaska conducted a emergency study to improve indoor air quality and address simple and affordable filtration strategies. Systems were installed in houses of people with a history of respiratory problems and air quality was monitored.
