What is an Air Leakage Test? An Air Leakage Test takes place near the end of the build phase when all of the elements of the building envelope (air barrier) are completed and sealed. These tests provide a measure of the amount of uncontrolled air leakage divided by the envelope area of the dwelling. Why Do you need it? Building Regulations Part L require that new build and existing buildings other than dwellings (i.e. non-domestic or commercial properties) complete Air Leakage Testing. This is due to the fact that gaps and cracks in the building fabric are often difficult to detect by visual inspection. Therefore, the only satisfactory way to show the building fabric is reasonably airtight is to measure the leakiness of the building fabric as a whole. It is your responsibility to commission air testing and to ensure this is carried out by a test body with approved qualifications and affiliations.
