Title: Interaction of Unvented Attics With Living Space in Three Northeast Homes

Unvented roof assemblies are becoming common in North American construction. It is estimated that over 100,000 have been constructed since 1995 (Schumacher 2007). According to RECS 2011, more than 30% of homes with attics can be found in the very cold/cold climate areas, which equals about 10.4 million housing units. The magnitude of these numbers emphases the significance of properly understanding how the attic conditions vary with respect to the conditioned space below.
