MINNEAPOLIS, MN — It’s a topic that some homebuilders would probably rather not address. And it’s going to take some getting used to. But mechanical ventilation for homes is an idea whose time has come, especially since today’s tightly built homes are even more likely to have ventilation problems than their drafty counterparts.
Residential IAQ was the subject of a symposium at ASHRAE’s summer meeting in Minneapolis. David Grimsrud of the University of Minnesota chaired the symposium. He told The News: “In Minnesota, the need for ventilation became clearer in new homes with tight construction where there were moisture problems. This came from clothes washing, cooking, and other normal activities.”
