The Study of the Effects of Building Arrangement on Microclimate and Energy Demand of CBD in Nanjing, China

This study aims to investigate the impact of building arrangement on the urban microclimate and energy consumption of buildings in central commercial and business district by using simulation tools, including ENVI-met and HTB2. In order to achieve this goal, a series of numerical calculations and building energy simulations are utilized to evaluate a total of 12 urban scenarios with various building arrangements. The results indicate a quantitative correlation between building arrangement and the microclimate and building energy performance at urban design scale. Furthermore, several recommendations have been provided for urban planners and designers as strategies and methods to mitigate the UHI effect and to reduce the energy consumption.
