Application of a generalised model of air infiltration to existing homes.

Presents examples of the use of a generalized model of air infiltration, developed earlier, to estimate the air infiltration characteristics of two test homes using data for the structures, weather and furnace installation. One of these is a single-storey home with basement of wood- frame construction, equipped with an oil-fired central heating furnace. The other is a 2-storey frame house equipped with a gas-fired central space heating furnace.< Also presents detailed methods used with the model to obtain the "total"effective crackage in each test home, the effect of wind shielding by adjacent structures and the characteristic permeability of the structure. Finds reasonable agreement between predicted and measured infiltration.
