ABSTRACT
While performing building energy simulations, weather data are among the most important pieces of information needed by models and tools. In urban conditions, the typical rural weather files should be modified to take into account the microclimatic effects in urban areas. This chapter presents an overview of the most relevant effects to be considered: shadows, long-wave exchange, urban heat island, urban ventilation patterns, and urban greening, presenting a modelling chain procedure developed by the authors and to be used in TRNSYS tool, as well as the result of simulations done for the cases of Rome (Italy) and Antofagasta (Chile).
