Air Permeability Test Certificates
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 standards 1 (2006) and must be shown to leak no more than 10m3/hr/m2 @ 50Pa or less than the given in your SAPS calculations.
Despite the legal requirement, an energy efficient building has many advantages, both financially and environmentally. |
