当代建筑运用“烟囱效应”原理的设计表达

Application of Principle of "Stack effect" in the Modern Architecture

“烟囱效应”是调节建筑内部空间自然通风的一种普遍原理.本文阐述了在建筑设计中运用“烟囱效应”的基本原理以及基于这种原理的建筑设计影响因素:季节因素和环境因素.结合当代建筑的实例,概括出应用这种原理具体的设计模式和方法:天井中庭、太阳能烟囱、呼吸式双层幕墙和环境风塔等.呼吸式双层幕墙就是通过这种原理减少外部空气对室内的污染,避免空气紊流等的一种设计模式.对“烟囱效应”的探讨以期在节约资源和降低环境负荷方面起到有益的作用.

＂Stack effect＂ is a general principle of regulating the natural ventilation of a structure＇ s inner space. The paper expounds the basic principle and mode of using ＂stack effect＂ in architectural design and probes into the affected factors in architectural design which are based on this principle： season factor and environmental factor. With several instances in modern architecture ,the paper summarized the specific designing mode and method by using this principle in the modern architectural creations such as atrium, solar chimney, and double-layer curtain wall and environmental tower.
