Airtightness is the measure of how much air leakage there is from a building. This is determined by carrying out an airtightness test, and the figure obtained from the testing is the air permeability value.
Air leakage can be measured by pressurizing or depressurizing the building to see how much air flows in or out of the building at a given pressure. Air tightness tests are useful to architects, building services designers, energy assessors, builders, services installers, fire sealers, air tightness testers, building controllers, building owners/ occupiers, etc. Airtightness testing is the best way to assess the performance of the building fabric in stopping the uncontrolled passage of air. It is also a very effective method of locating air leakage paths in a completed building.
Since the 2006 changes to England & Wales Building Regulations and 2007 changes to the Northern Ireland Building Regulations, airtightness testing has been mandatory for new buildings. In Scotland it became mandatory in 2011 starting with flats and maisonettes and later expanding to all new dwellings. In the case of new dwellings, a sample of dwellings on every development must be tested. Testers must either be registered through a scheme such as the ATTMA scheme, or demonstrate to building control that they are competent to test and are using UKAS-calibrated equipment.
A 3 Day training course
- At Level 1: Air tightness tester will be able to test dwellings and non-dwellings up to 4000m³ gross envelope volume and tested as a single entity as stated in EN13829 2001, with a single blower door fan set.
- At Level 2: Air tightness tester will be able to test both simple and non-simple buildings, those being any buildings except those defined as large and complex, high rise (LCHR), or phased and zonal hand-over.
This Level 2 course follows on from the BSRIA Level 1 course.
The Level 2 training course is broken into three sections: Advanced Envelope Areas, Airtightness Testing Theory and Airtightness Testing Practical. The course will culminate in examinations and assessments in all three aspects, following which successful candidates will be eligible to apply to ATTMA for Level 2 registration.
