The Energy Division is working toward development of ventilation systems capable of providing acceptable levels of indoor air quality in superinsulated houses. The research was designed to analyze and improve the indoor air quality of a superinsulated retrofit house located in St. Paul, Minnesota. The occupants had encountered 'stuffy air' problems after their house was superinsulated and weatherized to reduce heat loss, and uncontrolled air infiltration. High levels of CO2 build up were revealed indoors, despite the presence of a continuously operating air-to-air heat exchanger. Modifications were introduced and tested.
