Derivation of locally adjusted high-resolution weather information for building performance simulation

Abstract: Building performance calculations are usually done with regional weather files. Studies have proven that the microclimatic conditions vary widely within the urban area. This is due to the influence of the surrounding urban fabric (e.g. the materials used, the building structure and orientation, vegetation, etc.) and the anthropogenic heat emission on the aerodynamics, thermodynamics and the radiation, and therefore on the surrounding climatic conditions. In order to get more accurate results for the buildings performance, detailed information on the surrounding climatic conditions are needed. This paper compares and evaluates the possibility of generating microclimatic information using the example of a courtyard in Vienna. The results can later be used as input information for more detailed building performance calculations.
