Final answer:
The procedure to return the house to its original state using a blower door test involves closing all windows and doors, turning on all HVAC systems, and adjusting the thermostat to the minimum temperature.
Step-by-step explanation:
The procedure to return the house to its original state using a blower door test involves the following steps:
- Close all windows and doors to create a sealed environment.
- Turn on all HVAC systems to create a pressure difference between the interior and exterior of the house.
- Adjust the thermostat to the minimum temperature to simulate the worst-case scenario for heat loss.
- Conduct a blower door test by placing a blower fan in one of the doors or windows and measuring the air leakage using a pressure gauge.
- Based on the results of the test, identify any areas of air leakage and take appropriate measures to seal them, such as using weather stripping or caulking.
