The research of the building-integrated solar heat utility in the low-rise residential building Beijing area

Starting after the world energy crisis in 1972 to present concern over global warming, there has been a growing emphasis, which has become a necessary criterion, on integrating energy-efficient strategies in architectural designing to reduce fossil fuel consumption and its associated environmental pollution. In many instances, the development of building design strategies has been primarily dominated by factors such as function, economics, culture, and design trends. It is only recently that the design profession has become interested in quantifying the energy performance or environmental impact of the buildings. In the meantime, the solar heat considered as a kind of the recycled and green energy attracts people’s attention today especially for its utility in the building. For the consumption of the fossil fuel in China is becoming more and more, the utility of the solar heat in the residential buildings which consume a big proportion of the nonrenewable energy can surely decrease the total amount of energy use of the whole country.
As the climate of Beijing has the advantage of the utility of the solar heat, the paper is focused on the “The Utility of the Solar Heat in the Residential Buildings”.
The research is conducted in the following 4 aspects:
1. The utility of the passive solar heat in the design of the building-integrated solar thermal system.
2. The utility of the solar energy-hot water system in the design of the building-integrated solar thermal system.
3. The utility of the solar-wall in the design of the building-integrated solar thermal system.
4. The utility of BIPV system in the design of the building-integrated solar thermal system.
With lots of the data analysis made by software and site surveys and also by using the typology theory, this paper illuminates the view, which concludes the design method for both constructing the new dwellings and the rebuilding of the existing dwellings from the design of the internal space, external space and the skin of the building.

北京工业大学工学硕士学位论文 第1章 绪论 1.1 课题背景 1.1.1 国际背景 时至今日,全球能源形势已经非常严峻。据权威国际研究机构分析,世界一 次性能源仅够人类使用三十年,世界上唯一的超级大国美国,也加速了对世界石 油战略性地控制。2006 年内,能源危机依然困扰各国。 据有资料统计,如果全球的能源按目前的开发水平,那么地球上的石油将在 42 年后枯竭、天然气和煤炭也将分别在 66 年和 150 年后耗尽。同时,能源需求 的增长将导致污染物的排放的增加。因此,世界各国必须采取措施及制定相应政 策来减少温室气体的排放。数据表明,如果不采取措施,大气中的CO 2 含量将成 为现在 3.5 倍。而在全球日益增长的能源消耗中,建筑能耗占了相当大的一项, 约为一个国家总耗能的 30%-40%,因此,如何有效的降低建筑的能耗、减少建筑 对常规能源的依赖变得非常的重要,在不同区域国家和社会各界推进下,对可再 生能源的利用将成为建筑设计的新潮流。 1.1.2 国内背景 我国的能源现状也不容乐观,在常规能源资源上并不丰富,煤炭保有储量为 10024.9 亿吨,经查可采储量仅为 893 亿吨;石油的资源量为 930 亿吨,天然气 的资源量为 38 万亿立方米,现已探明的石油和天然气储量只约占资源的 20%和 6%,仅能够开采几十年。而且我国人口众多,占世界总人口 20%,人均能源资源 占有量不到世界平均水平的一半。 2004 年,全国电荒、煤荒集中爆发,半年多时间内,全国 27 个省遭遇电荒, 国家电网拉闸限电 80 多万次。能源紧张已严重影响国家经济命脉。我国的能源 问题的显露无遗,正面临一场真正的能源危机,节能迫在眉睫。 在我国,房屋建筑总面积在世界排名超过了所有发达国家,堪称世界第一。 但我国的建筑能耗十分巨大,在国家能源总消耗里占有重大比重:1996 年全国 能源消费总量为 13.88 亿吨标准煤,而建筑使用能耗为 3.54 亿吨标准煤,占全 国商品能源消费总量的 25.5%。1999 年全国建筑用商品能源消耗共计 3.76 亿吨 10
