The goal of this research is to find the most suitable computer simulation software for assessment of urban design performance from physical point of view. Although there are many physical simulation tools available today, there is no one which covers all the needs of urban design. After initial research of available software, we have chosen to assess three applications: ENVI-met, Project Vasar...

growing tendency for urbanization and rapid development of the cities has resulted in urban neighborhoods obstructing the access of each other to the natural sources e.g. solar energy, natural ventilation. sunlight as the main part of input energy in urban energy balance equation and natural lighting is of vital importance. this paper attempts to achieve an optimum morphology for residential bl...
