近些年来,能源危机、生存环境恶化等问题日益严峻,在此形势下,如何充分发挥利用生态节能技术、降低能源消耗、保护生态环境成为世界各国关注的共同课题,也是我国实现科学发展观的必然要求。本文提出了一种廉价的生态节能技术——自然通风,并对自然通风的原理作出全面分析,提出自然通风原理应被广泛应用于学校建筑设计中。 In recent years, the problems such as the energy crisis and the deterioration of the living environment are becoming more and more serious. Under these circumstances, how to make full use of ecological energy-saving technologies, reduce energy consumption and protect the ecological environment have become the common topics of concern to all countries in the world and also the realization of the scientific development concept in our country Necessary requirements. This paper presents a cheap ecological energy-saving technology - natural ventilation, and make a comprehensive analysis of the principle of natural ventilation, proposed that the principle of natural ventilation should be widely used in school building design.
