摘　　要：热缓冲空间环绕建筑的主要空间就形成了热缓冲空间层,它极具热调节和节能潜力。在自然通风方面,它对热压通风具有改善作用,但会影响非空调季的风压通风效果。通过风压通风模拟分析发现,缓冲空间宽度和迎风面双表皮开窗比是主要可优化因素,且存在相对优值。本次模拟显示:缓冲空间宽度宜控制,以保证穿堂风进深不大于层高的5倍;迎风面的缓冲空间宜设计成双表皮灵活开启形式,40%左右开窗比相对效益较好。Thermal buffering spatial layer is formed when main space of building is surrounded by thermal buffering space.It has obvious potential of thermal regulation and energy saving.When taking natural ventilation into consideration,it would enhance stack ventilation but influence performance of wind pressure ventilation in non-air-conditioning seasons.Through simulations and analysis of wind pressure ventilation,it is discovered that width of buffering space and opening rate of windward double skin are the major optimizable factors,which have relative merit figures.The width of buffering space is suggested to be controlled to ensure cross ventilation length is less than 5 times of floor height.The double skin of windward could be flexible opening and the opening rate could be around 40%to get relative benefit.
