The impact of new CIBSE weather data on natural ventilation design.

Type of article: Article

Summary

The authors investigated the impact of newly published CIBSE weather data on low energy buildings and the likely consequence on design. Emphasis was placed on the design assessment of naturally ventilated buildings. Three sets of weather data were applied and compared: CIBSE Example Weather Year (EWY), CIBSE Test Reference Year (TRY) and CIBSE Design Summer Year (DSY). The investigation focused on two locations only: London Heathrow to represent the southern area of the UK and Manchester Ringway to represent the northern area of the UK. The article compares the raw weather data in terms of frequency of occurrence of external temperatures, followed by two case studies using a dynamic building thermal simulation programme to quantify the impact of weather conditions on services design. The results were obtained by investigating the feasibility of a natural ventilation strategy, and the heating and cooling energy consumption if mechanical means are required to meet the internal comfort levels.
