In April 2006, Part L of the Building Regulations was
amended to help with the reduction of greenhouse gasses and
to ensure energy efficiency.
Improved building design &
construction, to reduce air leakage, is more cost effective
than further insulation or heating efficiency.
Since April 2006 all new buildings have to be designed to
comply with Part L of Building Regulations 2006:
-
All non-domestic buildings with a gross floor area
of 500m2 and above now
require a building air leakage / permeability
test.
-
A representative sample of domestic dwellings are
required to be air leakage / permeability tested.
A building has an air-tightness / air permeability / air
leakage rate, because of air leakage through cracks, gaps &
holes in the fabric of the building envelope, which are not
always visible to the eye.
Building air leakage testing & minimising air leakage not only significantly
reduces the energy consumption and CO2
emissions, but can also reduce the capital cost of heating
and ventilation plant due to the potential for plant
downsizing.
All testing is completed to follow Technical Standard 1
of Air Tightness Testing and Measurement Association (ATTMA).
