In 2006 updated Building Regulations pressure testing of buildings was brought in to ascertain the air permeability of new builds against their TER. The air leakage from a building has an effect on the efficiency due to heat loss over the building envelope as a whole, this is mainly due to poor workmanship on site.

Pressure testing is usually associated with larger developments & in the Building Regulations document L1A paragraph 63(b) does state that an alternative to pressure testing is to use a value of 15m3/(h.m2) for the air permeability at 50pa when calculating the Dwelling Emission Rate, although the effect of using this cautious value would then have to be compensated for by improved standards elsewhere in the dwelling design. With these improvements come costs, which when compared to the cost of the pressure test will more than likely out weigh any savings. Not only that but the client won't have the peace of mind that comes with the knowledge that their home has been built to a standard of workmanship which they & future generations can be happy with.

With our knowledge of energy efficient building techniques we at Staylor Design can supply our customers with all the relevant calculations & testing required. These are compiled by our own in house energy assessment & pressure testing engineers, giving our customers the best service & peace of mind possible.
