Numerical study of climate characteristics on the residential scale energy balance based on some typical cities

The energy balance of residential blocks in different climate zones is simulated and analysed. The influence of climate characteristics on the residential-scale energy budget is clarified, and the temporal evolution patterns of sensible heat flux, latent heat flux and heat storage flux in the surface energy balance are obtained. From the perspective of residential blocks energy distribution, ENVI-met simulation software is used to explore the laws of climate characteristics on the change of residential scale energy balance during summer and winter in three representative cities of typical climate zones in China.. Though surface energy balance simulations, vertical surfaces are found to be a significant source of net radiation received by settlements for northern regions and horizontal surfaces for southern regions. Most of the net radiation absorbed by the residential blocks during the day is transferred to the atmosphere in the form of sensible heat fluxes.
