Building Air Leakage Test Results

An air leakage test is a test to determine the level of uncontrolled air flow through gaps or cracks in the fabric of a building.

Building air leakage test results.

As leaders in building air tightness testing and facade leakage we offer advice solutions and on demand testing to deliver the results for your project with our attma registered air tightness testers located in melbourne sydney brisbane and perth. These results can be used to compare the relative airtightness of similar buildings determine airtightness improvements from retrofit measures applied to an existing building and predict air leakage. Use of this standard in conjunction practices. I ve worked on day long air sealing jobs that yielded anywhere between 10 frustrating to 30 satisfying reduction in air leakage.

These test methods produce results that characterize the airtightness of the building envelope. In essence it is a measure of heat loss through cold draughts. Building testing is not a mandatory test prescribed in building codes but a performance based option that many designers are requiring. With few exceptions new dwellings will require an air leakage test as part of the building control post construction sign off procedure.

It s importanat to know what you ve achieved. Testing the completed using both pressurization and building depressurization and documenting that the air leakage rate of the building thermal envelope does not exceed 0 25 cfm ft2 under a pressure differential of 0 3 in.
