Air testing (also known as Air Permeability, air leakage test and pressure test) is a measure of showing how good your building is at keeping the head in and the cold out. All new developments in the UK are required to have an air test carried as part Approved Document Part L (England and Wales) and section 6 of the technical handbook (Scotland).
It’s an essential part of meeting Part L1 & L2 Building Regulations and contributes to the SAP/SBEM calculations which help determine your building’s environmental rating. The Air test will always be carried out once the building has been finished and before the occupier moves in. In essence, the lower the air leakage, the better the building is at keeping out the cold and the lower the energy bill will be.
