PART L2 of the Building Regulations (Conservation of fuel and power) has been amended with effect from 1st April 2006 and now includes a test for Air Leakage. Buildings requiring compliance to part L2 with a gross floor area of greater than 500m2 will require an air leakage test carried out in accordance with ATTMA technical standard 1 (2006) and must be shown to leak no more than 10m3/hr/m2 @ 50Pa or less than the figure given in your SAPS calculations.
Despite the legal requirement, an energy efficient building has many advantages, both financially and environmentally. You can saving money with lower heating costs as well as reducing carbon dioxide emissions which help preserve the planet for the next generation.
We can arrange your Air Leakage test and attend on the same day as the test to seal any identified leaks giving your property the best to pass in one visit.
