Blower Door Testing
Blower Door Testing for New Construction
New Homes require a blower door test to meet residential building codes. Solaire Energy works with many builders to provide blower door tests for new construction. We serve building contractors throughout northern and central Pennsylvania. We provide builders with a written report to provide to code inspectors.
A blower door test is done by placing a heavy duty fan with a canvas shroud in a doorway. The fan depressurizes the house to a standard pressure, and measures the air leakage rate with pressure gauges.
The window of time to schedule the blower door is after drywall is installed and air sealing measures to the thermal envelope are complete. Solaire quickly responds to your need for a test, as we know how important your deadlines are.
The building code requires new homes to be airtight, 5 ACH (air changes per hour) with the blower door running. For reference, this translates to about .20 air changes per hour naturally. This means about 5 hours for one complete air change in the house.
Pennsylvania is under the 2015 International Energy Conservation Code (IECC), part of the 2015 International Residential Code.
Blower Door Testing for Existing Homes
Solaire also provides blower door tests for many existing homes. This is important for planning home improvements such as insulation and air sealing. Stopping air leakage can also improve the health and safety of a home. For example, indoor air quality can be compromised by drawing pollutants from basements, such as radon or mold.
