E-House Blower Door Testing

Quantify and Identify Air Leakage in the Building Envelope of an E-House:

The performance of the building envelope of an E-House can be measured and air leakage locations identified using blower door equipment to both depressurize and pressurize the structure. Building envelope testing is an important (and often overlooked) part of the E-House QC and evaluation process.

How is an E-House Blower Door Tested?

A powerful fan, framework and shroud is setup in an exterior door of a building or structure. Data from a series of depressurization and pressurization readings at a variety of fan speeds is entered into software to quantify the performance of the building envelope. A standard goal (required by energy codes in some states) is to achieve .40 or less CFM of air leaks per SF of building envelope at -75 pascals of pressure. The blower door test typically will include use of smoke to identify air leaks, infra-red camera imagery (depending on temperature differential) and our expertise at finding air leakage locations.

I'm pleased to share a word of appreciation for the work A-A Exteriors did for our condo association. They conducted a blower-door test for our six-building, sixty units. This was a complex project. It required coordinating a large number of people and adapting to a variety of problems in each building.

I wanted to thank you for the air testing and thermography testing you recently completed for us at the US Armed Forces Reserve Center at the Letterkenny Army Depot in Chambersburg, PA. Both yourself and your onsite staff were very considerate of our needs working in and around a project that was still under construction, while at the same time completing your work very efficiently and timely.
