On Monday, Chaz Steffen, a 3rd Party Energy Verification Consultant for Envinity visited GreenBuild to do air leakage testing of both houses, using a blower door test. He sealed up the front door of each home, and used the fan in the door seal to blow air out of the home. Once the house was depressurized he used an infrared camera to find spots where cold air was entering the home. His is just one of several blower door tests that will help guide construction of these homes toward net zero energy readiness.
