Development of the air infiltration model for the energy performance design system.

Describes the Energy Performance Design System (EPDS) which is a simplified procedure for energy analysis based on extensive field testing, laboratory experiments and computer modelling. Provides a simple procedure for designing and evaluating the performance of energy-efficient homes. Describes thedevelopment of the simplified air infiltration model used in EPDS. The starting point for model development was a series of field studies on air infiltration conducted 1978-1981. These studies included pressurization tests on 57 central Ohio residences, in addition to natural infiltration measurements on 3 unoccupied ranch-style homes and 3 unoccupied double-wide mobile homes using tracer gas techniques. The results of these experiments are reduced to a simplified model based on the concept of leakage area.
