Abstract: Nowadays thermal, environmental performance of buildings and systems are investigated mainly through building simulation software. The prediction of the building performance requires an updated long-term weather database by the generation of a comprehensive database, socalled Typical Meteorological Year (TMY). However, the majority of methods and studies on the generation of TMY are employing the default weighting indices, resulting in a gap of basis of assigned factor for meteorological parameters. In essence, this paper investigates the impact of weighting factor and climatological variables, on the implementation of TMY in particular simulation studies. A statistical analysis has been carried out, and the results show that for solar applications, the TMY mainly driven by the global radiation, demonstrate the best performance. Similarly, for the simulation case of a wind turbine, the best performance achieved by the TMY, based on the wind profile. The cooling and heating mode of a building are better described by the weather data set that is influenced from all the meteorological parameters. Thereby, on enhancing the precision and accuracy of results at building simulation analysis, the weighting factors of the environmental parameters must be driven by the intended use of the weather file.
