Analysis of the Influence of Natural Ventilation on Thermal Buffering Spatial Layer of Building
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.
