Dynamic thermal modelling was used to compare energy consumption and internal temperatures of office buildings situated in the South (London Heathrow) and the North (Manchester Ringway) in winter and in summer using three sets of weather data supplied by the Chartered Institution of Buildings Services Engineers (CIBSE). The data sets were: Example Weather Year (EWY), which was original data; and Test Reference Year (TRY) and Design Summer Year (DSY), which were new. The feasibility of natural ventilation was investigated, and heating and cooling energy requirements determined should mechanical systems be required to meet internal comfort levels. Use of the new data resulted in reduced heating and increased cooling demands. The feasibility of natural ventilation was dependent upon which data was used. 4 refs.
