Above, the blower door test: a frame and fan were set up and air was forced out of our house. Leaks were discovered as cold outside air came in to fill the void. A computer read and recorded the results. Our leakage primarily occurred around pot lights, wall electrical outlets and in some windows. A score of 80 is required to qualify the home as efficient. Our house scored an 84.
We were the first Owner/Builders and the first prefab home to be tested by this consultant and she was impressed with the measures we had taken and pleased with the outcome as 84 is considered a good score. How good will be proved by future heating bills.
