How Building Pressure Tests Work
During a building pressure test, a specialised rig is used to pressurise or depressurise the building or specific rooms. The process involves carefully recording pressure and airflow data to determine the air leakage rate. For a more precise understanding of leakage points, smoke generators or thermal imaging technology can highlight specific areas where air escapes. These visual aids allow construction teams to identify and address the exact sources of leakage, contributing to a more airtight and efficient structure.

Advantages of Building Pressure Testing
A key advantage of pressure testing is the energy savings it provides. By pinpointing areas of air leakage, pressure testing enables targeted sealing work that can lead to lower energy costs over the building’s life. Additionally, airtight buildings experience fewer draughts, which improves comfort for occupants and stabilises indoor temperature and humidity levels. With these improvements, mechanical ventilation and air conditioning systems can function optimally, reducing the building’s overall carbon footprint.
