一、前言建筑是用能大户,建筑节能是发展建筑业的需要。在发达国家,适宜的室温已经成为一种基本的需要。我国是发展中国家,根据国家的经济实力,过去国家规定长江以南地区为非采暖区,而长江以南的的许多地方冬季潮湿寒冷,夏天闷热,寒冷和酷暑都使人感到很不舒适。随着国家建设和经济的发展人们的生活质量要求不断提高。长江以南的许多地区,用上了空调。公共建筑中有了中央空调,与人生活关系最密切的,占城市建设总量 50%-70%的居民住宅则也安装了各式各样的空调,住宅建设耗能迅速增长,其增长速度大大地高于能源生产的增长速度。住宅重要意义也逐步受到重视。如何在住宅建筑设计中,更好地利用自然能源,提高住宅建设中能源的利用效率,则是建筑师要探讨的课题。
First, the preface Construction is to use energy, building energy efficiency is the need to develop the construction industry. In developed countries, suitable room temperature has become a basic need. China is a developing country. According to the economic strength of the country, in the past, the state stipulated that the area south of the Yangtze River should be a non-heating area. In many places south of the Yangtze River, the area is humid and cold in winter, and it is very uncomfortable to find it hot, cold and hot in summer. With the construction of the country and the development of economy, the quality of life of people is constantly increasing. In many areas south of the Yangtze River, air conditioners are used. Public buildings with central air conditioning, and the most closely related to people's lives, accounting for 50% -70% of the total urban construction of residential buildings are also installed a wide range of air-conditioning, residential construction rapid growth in energy consumption, its growth rate Greatly higher than the growth rate of energy production. The importance of housing is also gradually taken seriously. How to make better use of natural energy and improve the efficiency of energy use in residential construction in the design of residential buildings is an issue to be discussed by architects.
