Abstract	The performance of vapor barriers in typical residential walls is investigated through numerical analysis. A two dimensional heat, air, and moisture transport model that simulates transient effects is used. 1Wo series of calculations are performed. In the first series, the wall is exposed to constant boundary conditions, representative of typical heating periods, for a fixed interval. In the second series, the exterior conditions are chosen to be representative of three Canadian locations, Vancouver, Winnipeg, and Ottawa. In each series, six different levels of vapor resistances are imposed. Each of these cases is simulated for each location for a two-year period.
