Air permeability testing plays a key part in establishing the energy efficiency of a building – and as regulations tighten it will be increasingly necessary to make design considerations for air tightness early on in a build. On – completion testing measures the effectiveness of your air leakage strategy by establishing routes of leakage in the finished envelope.
If a test fails or there is more leakage than planned, a good test engineer will be able to indicate leakage areas, and in most cases suggest suitable remedial measures. DEAP Calculations are used to determine the energy performance of a dwelling, and it is within that assessment that a design, target air permeability will be set. This is a number below 7m3/h/m2 at 50 Pascals as a back stop value under the current Regs., but increasingly likely to be under ’5′ due to ever more stringent client requirements.
