Abstract:
Buildings have a significant share of global energy consumption and a major role in global warming. Buildings also affect the temperature of their surrounding environment. This paper investigates the effect of Floor Area Ratio (FAR) and urban block configurations on energy consumption, urban microclimate, and outdoor thermal comfort in Tehran with a hot climate, using the simulation method and Ladybug Tools (1.6.0). According to the results, decreasing FAR in an urban block improves urban microclimate while reducing building energy consumption. The results reveal that the effect of FAR on the buildings' energy consumption is more considerable. Decreasing FAR reduces the buildings’ energy consumption and outdoor air temperature. Furthermore, the scattered form of urban blocks consumes the highest cooling energy while having the lowest heating load. The lowest cooling and heating loads are found in the linear and scatter organizations. Considering the dominant cost of cooling energy, the case with less FAR would be the best choice from an economic point of view. For three-story urban blocks, the best case is the courtyard form, while for five and nine-story urban blocks, the best option would be the linear form.
