Blower Door Test in Wenonah, NJ

How Is A Blower Door Test Conducted?

During blower door test in Wenonah, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Wenonah, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving this goal during your blower door test in Wenonah, NJ promotes energy savings and demonstrates adherence to local building rules.
