Air Pressure Testing (Air Leakage)

With the introduction of maximum admissible leakage rates for non-domestic buildings as specified in Conservation of Fuel and Power Building Regulations 2000, the requirement for testing buildings for air leakage is a statutory requirement for new buildings over 1,000 m2.

BDAS provides a whole building pressurisation test service that determines building envelope leakage rates for comparison against clients specification or Building Regulation Part L2 standards. Testing is undertaken in strict accordance with CIBSE TM23 determining the criterion for testing buildings for air leakage. BDAS will identify leakage paths and specify any remedial action, if required.

Background Information

Air leakage is now a focus of the government initiative to reduce carbon emissions across Britain. UK Building Regulations (Part L) will soon require all new premises over 1000 m2 floor area to have air leakage less than 10m3 / hr / m2.

"Air-leakage" is a phrase widely used to describe the "uncontrolled movement of air out from a building". It refers to air outlets in the building envelope that are due to weaknesses in design or construction. Failures in a building's air leakage levels will account for a substantial part of energy losses for the proprietor. Good air tightness in a building reduces capital spend on heating and ventilation, reducing running costs and increasing occupier comfort.

BDAS will resolve your building's air leakage, and in turn; reduce your costs, save you time, and help you protect the environment.
