Programmed computer model of air infiltration in small residential buildings with oil furnace.

Describes computer program for the prediction of the air infiltration load in small residential buildings. The model represents an oil-fired furnace, a smoke pipe with barometric damper, a chimney and a non-partitioned building, with leakage openings in the building envelope. The model can be used to predict the air change rate of a small house under various combinations of indoor/outdoor temperature, wind-speed, wind direction and operation of an oil fired furnace. The program has been tested against air change rates measured by the tracer gas technique on a one-storey house under various indoor/outdoor climatic conditions. Finds for this particular test houseagreement between calculated and measured air change rates is within 25%.
