【摘要】：随着社会经济的飞速发展,工业化、城镇化和人民生活水平的提高,对居住环境的舒适性要求的提高,建筑的用能种类进一步增多,建筑消耗的常规能源有增无减,常规能源的资源已经面临枯竭,严重威胁到了国家能源安全和经济可持续发展。而新的非常规能源的开发在短期内因为各种原因很难缓解当前的能源问题。进一步提高建筑的节能成了缓解当前能源问题的有效途径。我国自20世纪80年代初开始,采取分阶段提高建筑节能,以后下一阶段在上一阶段基础上节能30%。1986年~1995年是我国建筑节能的第一阶段,我国制定了第一部建筑节能设计标准《民用建筑热工设计规程》JGJ24-86,其基本目标是将采暖能耗从当地1980到1981年住宅通用设计的基础上节能30%。至今,全国建筑节能已基本达到了第三阶段,即节能65%的要求,部分城市已率先实施第四阶段75%的节能目标。西安,作为我国古都之首,七大区域中心城市之一。2007年实施节能65%的标准距今已有八年,在这八年里,保温材料、设计水平及城市经济都有显著的提高。本文正是基于国家节能大趋势和西安地区的经济技术现状,试图探讨西安地区高层住宅从节能65%提高到75%技术方面的可行性。本文以代表性的高层住宅建筑,在满足建筑规范条列的情况下,通过改变代表性的高层住宅建筑的层数、层高、窗墙面积比等参数,研究了它们与建筑采暖能耗的关系,对建筑节能优化设计提出了一些建议。根据西安地区高层住宅建筑节能75%的建筑物采暖耗热量指标,反推各围护结构传热系数限值,并进行了节能75%校验。然后根据限值,以西安地区现有节能构造做法为基础,对西安地区高层住宅节能75%的围护结构构造做法提出可行的技术体系。最后根据新的技术体系,评估了西安地区高层住宅节能75%经济效益。通过对西安地区高层住宅节能75%的研究,得出西安地区建筑节能设计标准中的相关参数及可行性技术。
[Abstract]:With the rapid development of social economy, industrialization, urbanization and the improvement of people's living standard, the demand for comfort of living environment has been improved, the kinds of energy used in buildings have increased further, and the conventional energy consumption of buildings has increased unabated. The resources of conventional energy have been exhausted, which has seriously threatened the national energy security and sustainable economic development. The development of new unconventional energy is difficult to alleviate the current energy problem for various reasons in the short term. Further improvement of building energy conservation has become an effective way to alleviate current energy problems. Since the beginning of 1980s, China has taken steps to increase building energy efficiency in stages, and the next stage is the first stage of building energy conservation in China from 30.1986 to 1995 on the basis of the previous stage. The first building energy-saving design standard JGJ24-86has been formulated in China. The basic goal of JGJ24-86 is to save energy on the basis of the general design of residential buildings from 1980 to 1981. So far, the national building energy conservation has basically reached the third stage, that is, energy saving requirements of 65%, some cities have taken the lead in the implementation of the fourth stage of 75% of the goal of energy conservation. Xi'an, as the first of the ancient capitals in China, is one of the seven regional central cities. It has been eight years since the implementation of the energy saving standard of 65% in 2007. During these eight years, the thermal insulation materials, the design level and the urban economy have improved significantly. Based on the general trend of national energy saving and the present situation of economy and technology in Xi'an area, this paper attempts to discuss the feasibility of improving the technology of high-rise residential buildings in Xi'an from energy saving 65% to 75%. In this paper, the relationship between the building heating energy consumption and the building heating energy consumption is studied by changing the parameters of the representative high-rise residential building, such as the number of floors, the height of the floor, the area ratio of window to wall, and so on, under the condition that the representative high-rise residential buildings meet the requirements of building codes. Some suggestions on optimal design of building energy conservation are put forward. According to the heat consumption index of buildings with energy saving 75% in high-rise residential buildings in Xi'an area, the limit value of heat transfer coefficient of each retaining structure is pushed back, and the energy saving 75% check is carried out. Then according to the limit value, based on the existing energy saving construction method in Xi'an area, a feasible technical system is put forward for the 75% energy saving enclosure structure method of Xi'an high-rise residence. Finally, according to the new technical system, the 75% economic benefit of energy saving of high-rise residence in Xi'an area is evaluated. Based on the study of 75% energy saving of high-rise residential buildings in Xi'an area, the relevant parameters and feasibility techniques in the design standard of building energy saving in Xi'an area are obtained.
