The 'Low Pressure PULSE Air Test Process' is a new way of testing the airtightness of buildings. The 'PULSE' test unit is a compressed air-based technology which releases a specific amount of air from a compressed air tank into a building and measures the building's pressure response. The 'PULSE' software analyses the test data and calculates the building's air permeability at 4Pa.

Low Pressure PULSE Air Test Process received its Statement of Verification on 13 June 2019 (Verification Number VN20190035).
