What is Domestic Air Leakage Testing?
House Air Tightness Testing (Commonly referred to Air Leakage Testing or Air Pressure Testing) is a mandatory requirement for part L1A and L2A building regulations for all newly built houses (Commercial and Domestic).
An Air Tightness Test is an energy audit that identifies any areas of unwanted air leakage in a building’s thermal envelope and should not take any longer than an hour to conduct.
The main reason for an Air Tightness Test is to create a more airtight building which in turn will reduce C02 emissions and lead to a reduction in heating costs and unwanted air leakage.
1 Arrival on site
Wind speed, air temperature and barometric pressures will be taken prior to testing. Quick check of building dimensions.
Placing fan(s) on an external opening. Close all windows and external doors and tape ventilation terminals.
Take depressurised measurements from inside the building. Check for air leakage paths.
Provided verbally to the client once the air pressure test has been completed. Certification will be issued within 24 hours.
Completing your Domestic Air Leakage Test
Purple Energy have a dedicated team of engineers working throughout the country to provide accurate testing and invaluable remedial advice, ensuring you achieve the results you require to pass part L building regulations.
The test is a relatively simple and hassle-free experience if the appropriate guidelines are followed prior to our visit. One of our engineers will place a fan or number of fans to an appropriate opening. This is usually an external door. They will then proceed to take multiple readings at different pressures.
Before the test is completed we will tape all of the ventilation extracts, turn off any HVAC units and ensure all windows and doors have been closed.
If there are site works in the dwelling during the testing process they must ensure windows are kept closed and doors are not tampered with. The tightness test procedure should not take more than 45 minutes to complete, after which our engineer can provide you with an air pressure reading.
A Guide to Success
Following the recommended guidelines below will provide the relevant information for a successful air pressure test:
No sealing around skirting and windows
Lack of sealing around piping leaving the building
Incorrect installation of loft hatch
Down lights not installed
Holes in walls and ceiling
Our engineers will be able to find where air leakage is occurring within the dwelling and provide the appropriate remedial work to help you achieve the result you are looking for.
