我们生活在这样一个历史时期,它比任何时候都严峻地意识到世界面临的能源问题。目前人们普遍认为,化石燃料的贮量是有限的。从多年来的统计数据看,能量的消耗仍在不断地增长。因此,化石燃料不能无限制地满足人们日益增长的需要。然而,太阳能却是一种没有污染的充足能源。在建筑领域内,太阳能采暖是最有现实意义的应用项目之一。目前世界上以各种形式应用太阳能的建筑物数以万计,而且数量在不断地增加,各国政府都非常重视这项研究,为其投入了大量的人力物力。太阳能的应用已经从住宅建筑发展到办公楼、学校、体育馆、医院等公共建筑。比较闻名的有英国沃拉西的圣乔治中 We live in such a historical period that it is gravely aware of the energy problems facing the world more than ever. It is generally believed that the storage of fossil fuels is limited. From years of statistics, energy consumption is still increasing. Therefore, fossil fuels cannot meet people’s growing needs without limit. However, solar energy is a kind of energy without pollution. In the field of architecture, solar heating is one of the most practical applications. At present, there are tens of thousands of buildings that use solar energy in various forms in the world, and the number is constantly increasing. Governments of all countries attach great importance to this research and invest a lot of manpower and material resources for it. The application of solar energy has grown from residential buildings to office buildings, schools, gyms, hospitals and other public buildings. Well-known in St. George’s, Wallassi, United Kingdom
