自然通风（或机械辅助式自然通风）是当今生态建筑中广泛采用的一项技术措施，其应用目的是：尽量减少传统空调制冷系统的使用，从而减小能耗，降低污染，同时更有利于人的生理和心理健康。自然通风的理论依据是利用建筑外表面的风压和建筑内部的热压在建筑内产生空气流动。但对于不同类型的建筑（不同进深，不同高度，不同用途）来说，实现自然通风的技术手段各不相同。文章从建筑通风这一特定的角度对几个耳熟能详的建筑范例做出新的分析，旨在揭示建筑通风技术的重要性和复杂性。

Natural ventilation. or mechanic supplied natural venfilation is one of the widely adopted fechniques in ecology oriented architecture. its main objective is to try fo decrease the frequency of using the traditional air conditioning system. so as to save energy, reduce pollution and promote the poysiological and psychological health of mankind, me theory of natural ventilation is based on the wind pressure on the envelope of the building and the thermal pressure inside the building. However in order to realize nafural ventilation the technique varies considerably with different types of buildings, for example different depths different heights. and different functions, By analyzing some well-known architecture from the special view of building ventilation, this article tries to point out the importance and complexity of building ventilation technique,
