As an energy efficiency specialist, it’s crucial to know that PART L2 of the Building Regulations was amended as of 1st April 2006, and now includes an essential Air Leakage test. Buildings larger than 500m2 must comply with this regulation and conduct an air leakage test following the ATTMA technical standard 1 (2006). The building must demonstrate that it leaks no more than 10m3/hr/m2 @ 50Pa, or less than the number given by SAPS calculations.

But why is air leakage testing so important? Firstly, it ensures that a building is energy efficient- something that has significant advantages. Lower heating bills, for example, can save a lot of money. Reducing carbon dioxide emissions can also preserve the environment for future generations.

Secondly, air leakage testing helps identify possible leaks that affect the property’s energy efficiency. Leaks can cause discomfort, reduce indoor air quality, and decrease the building’s lifespan. By conducting air leakage testing, you can identify potential issues and make modifications to save energy, reduce costs, and create a more comfortable environment.
