Clip Summary
Janet MacIlvaine and George James (from the Department of Energy) show Bob how they conduct a blower door test. The blower door is used to measure the amount of air leakage in the building. Today's tighter homes need controlled ventilation, which is provided in this home by a Tamarack Preventilator exhaust fan. The fan has special controls that continuously maintain a slow ventilation rate. Ultimately, the test shows that the house is both well-sealed and well-ventilated.
