Examines those factors which can influence leakage distribution, including building style, construction quality, materials, ageing, pressure and variations in humidity.
Contains analyses of ten models developed in five participating countries. These range in complexity from 'single-cell' to 'multi-cell' approaches. Also contains numerical and climatic data for fourteen dwellings compiled to produce three key datasets which were used in model validation study.
Air infiltration and ventilation heat loss can account for a substantial proportion of a buildlng's space heating demand. Therefore, in the planning of energy conservation measures, the influence of air exchange demands very careful consideration. Unfortunately, air infiltration is particularly difficult to measure. This is because not only is it dependent on building airtightness, and hence the quality of construction, but it is also significantly influenced by prevailing climatic conditions, surrounding terrain and the actions of occupants.
