The test measures air leakage rates through a building envelope under controlled pressurization and depressurization.īuilding testing is not a mandatory test prescribed in building codes, but a performance-based option that many designers are requiring. Energy Savings and Moisture Transport CalculatorĪir tightness testing is a process in which the building envelope is tested to quantify the air tightness.Evaluated Air and Water-Resistive Barriers. ![]() Whole Building Airtightness Technician Courses.Whole Building Airtightness Program (WBAP).Certified Air Barrier Specialists (CABS).Then, with infrared thermography, smoke sticks, and fog machines, we are often able to pinpoint the location of the air leakage. During the testing, we typically test different floors, sections, or "wings" of a building to determine where the air leaks are occurring. In addition to just testing to various standards, we also can perform diagnostic analysis.

However, with recent changes to building codes, federal building requirements, and other standards or programs (Energy Star, LEED, Canadian R-2000, etc.), we are now performing door blower tests on all new commercial and multi-family buildings, and performing door blower tests on existing commercial buildings to determine location(s) of air leakage, moisture management, internal pressure gradients, humidity control, comfort, or other building envelope issue. Until recently, most door blower tests were performed only on residential or small, non-residential structures. Over the past 20 years, this method has become the gold standard for determining how much air leaks through a building enclosure, also called the building envelope. ![]() The air leakiness of a building can be quantified by a door blower test, where a calibrated fan is installed into an exterior doorway and the building is depressurized and/or pressurized.
