Numerical Simulation of Impact of Building Layout on Spatial Comfort

Abstract:

The airflow and pressure around buildings of a typical training center were simulated using RNG kε turbulence models. The results show that considering the prevailing wind direction in different seasons, the semi closed layout is good for ventilation in summer and keeping warm in winter, which benefits outdoor activities. The pressure differences between windward facade and leeward facade fluctuates significantly with the change of height, so the corners of certain floors need auxiliary means to improve the room ventilation. Based on the analysis of wind velocity, pressure and air age around the buildings, some suggestions are offered to the improvement of resident comfort and building energy conservation.
