AbstractAddressing air leakage of dwellings is important to improving energy efficiency and thermal comfort. This paper reports on the air permeability test results of 287 post-2006 new-build dwellings in the UK. The paper explores the relationships between air-tightness and its influencing factors including build method, dwelling type, management context, design target, season, number of significant penetrations, and envelope and floor area. One-way ANOVA analysis was utilised to compare means of air permeability in relation to the individual factors, and two- and three-way ANOVA analyses were applied for examining the interactions between them. The air-tightness of the dwellings averaged 5.97m3/(hm2) at 50Pa, which has improved from UK historic data. Dwellings built using precast concrete panels were significantly air-tighter than those built using timber frame, whilst those masonry and reinforced concrete frame dwellings were most leaky. Greater extent of innovative practice and 'self-build' procurement led to achieving superior air-tightness. Interaction was observed between 'build method' and 'dwelling type' and between 'dwelling type' and 'management context'. A modest positive correlation was noticed between air permeability and design target, which became weak in relation to the number of significant penetrations and envelope area. Applying the linear regression technique a predictive model is developed for estimating air permeability of dwellings. This model integrates the influencing factors and their significant interactions. The findings should contribute to future research in predicting impacts of controlling the influencing factors on achieving air-tightness of dwellings more consistently. © 2010 Elsevier Ltd.
