The calculation method has been applied to produce a better understanding of the effects of air movement and discontinuities on the performance of lightweight roofs. The development of the assessment method involves the definition of design climate values for the evaluation of condensation risk due to air leakage, the definition of limit state values to assess the risk and the use of 'redundant' protective measures to reduce the risk. The research produces tools and recommendations for the design of lightweight roof systems with reliable control of interstitial condensation.
