Blower Door Test, Infrared Camera Audit

Service Description

A blower door test shows the total amount of air leakage in a home. Having a tighter home improves energy efficiency, and saves money on energy bills. The building tightness standard for Montana is targeted at 4 air changes per hour (measured at 50 Pascals pressure control), or 4 ACH50. The energy code requires air sealing around windows, doors, electrical boxes on exterior walls, and ceilings and openings where pipes and wires pass through the building shell. Air leakage is often responsible for 10 to 30 percent of total home energy loss. Check to see if pipes, wires and utility lines, and other openings have been sealed. Most of the air leakage sites will be hidden in the attic, walls, and floor. Because the house is sealed for comfort and efficiency, it is important to ventilate the house in a controlled way. An infrared (IR) camera shows the temperature of the house’s surfaces. Improperly insulated areas will appear colder than expected in winter and warmer than expected in summer. Consider having an IR Audit to confirm the house has been properly insulated. An IR investigation conducted with a blower door analysis can detect air leakage.
