Building Permeability

Building fabric that allows uncontrolled air flow - leaky buildings - can lead to increased energy usage and poor air quality from pollution or moisture ingress. The measure of air leakage in a building may also be used as a surrogate measure of build quality.

As buildings become more and more energy efficient, the greater the percentage of energy consumption may be due to air leakage, and therefore the importance of building tightness will increase over time. For instance mandatory efficiency rating of new buildings in Britain includes verification of the building fabric tightness. QED conducts permeability testing to assist in predicting NABERS energy ratings, permeability being a key variable in building energy simulations.

Our staff has been trained in procedures for following the ATTMA Technical Standard L2, The Air Tightness Testing & Measurement Association, October 2010.
