自然通风在绿色建筑中的应用

Application of Natural Ventilation in Green Building

自然通风依靠室外风力造成的风压和室内外空气温度差造成的热压,促使空气流动,使得建筑室内外空气进行交换,不消耗能源即可满足室内良好的空气品质,是促进建筑节能的重要技术。介绍了自然通风在绿色建筑中的功能及常见的3种利用形式,为绿色建筑中推广自然通风技术的应用提供参考。

Natural ventilation depends on the wind pressure caused by outdoor wind and the thermal pressure temperature caused by air temperature difference between indoor and outdoor, which can make the air flow and accelerate air exchange of building indoor and outdoor. It is an important technology which can promote building energy efficiency, because indoor air quality can stay in good without energy con-sumption by it. The function of natural ventilation in green building is expounded, as well as three kinds of natural ventilation commonly used, which can provide reference for promoting the application of natural ventilation technology in green building.
