Natural ventilation of single family houses. Ventilation naturelle des maisons individuelles

Reports the results of three programmes of measurements of ventilation carried out in one-family houses, which in most cases were of the 'council house' type. The first programme measured ventilation rates using tracer gasin two houses room by room. Wind speed and direction were recorded but no general relation between ventilation and wind was found. The second measured ventilation rate in individual rooms in a house under six different wind conditions. The third measured ventilation rates in three identical homes. Joints and windows were pressure tested for air leakage and the air infiltration through these windows was calculated from wind pressure coefficients. Finds that proportion of air through windows was 8.9% and 32.9% in two of the houses. Discusses results and suggests further work.
