Abstract

The rapid growth of population has promoted the construction of the megatall buildings taller than 600 m whose height might bring new issues to the building energy saving. To investigate the effect of the building height on the distribution of thermal pressure in megatall buildings, we simulated the thermal pressure distribution and air infiltration using the multi-zone network model CONTAMNv3.2. The building models were set up considering the typical conditions with height interval of 200 m ranging from 600 to 1000 m, and the outdoor meteorological parameters were set up based on the temperature ranges according to the cold region and the sever cold region in China. It is revealed that the thermal pressure increases with the increase in the building height, together with the decrease in the outdoor temperature. Besides, the energy consumptions from the air infiltrations were calculated based on the same conditions, among which the variation of air density was considered. The findings can be exploited to reduce the energy consumption of air infiltration in the megatall buildings.
