Abstract
The HEALTH-V study evaluated health and environmental outcomes associated with two ventilation approaches taken in existing homes. The number of homes studied was 52 in the Chicago area and 35 in Indiana. The control homes were weatherized based on ASHRAE 62- 1989 and the treatment homes were ventilated to ASHRAE 62.2-2010, both in the course of weatherization (wx) energy retrofit. One of the outcomes studied was humidity using moisture balance-the comparison of vapor pressure excess indoors with outdoor temperature. Excessive moisture has been linked to mold, asthma, pests and other healthy housing deficits. The house moisture balance was evaluated pre-wx and post-wx. Low moisture balance represents drier conditions indoors. This study found that there was a significant lowering of moisture balance following weatherization with both ventilation approaches. The study also found that the 62.2 treatment showed a significant lowering of moisture balance compared to control (62-1989).
