Caswell Hill infiltration work-study project. Final report.

Reports on a project carried out in the Caswell Hill and Riversdale areas of Saskatoon to investigate the effectiveness of sealing with caulking and weatherstripping to reduce air leakage. This involved sealing 10 homes, and also insulating the attics and basements of five of these houses after thesealing work. A control group of 10 homes which had been insulated without particular attention being given to sealing procedures were also monitored. The homes were pressure tested by the National Research Council before and after sealing to measure the reduction in air leakage. Meter readings were taken after retrofitting and compared with energy consumption data for the previous 3 years on each house. There was a greater percentage reduction in fuel consumption for houses which were sealed before insulating.
