【摘要】：20世纪70年代发生了能源危机,从这之后节能减排和可持续发展成为世界一致认同的保护环境观念。其中建筑节能的发展是共同关心的热点话题之一,而且在建筑行业是一个非常重要的问题。建筑节能包括新建建筑节能和既有未达到节能标准建筑的节能。在各类建筑中,有大量的既有居住建筑,而且大多数住宅建设的初期没有采取有效的节能措施,达不到节能设计标准,这些住宅的外围护结构保温、隔差性能比较差,设备比较落后,从而导致采暖严重浪费。因此,对未达到节能设计标准的既有建筑的节能改造是节能建设工作的重要组成部分,也是实现节能目标的重要组成部分。随着高层住宅的迅速发展,几乎总是有很多能耗高、外围护保温性能差和舒适性差的旧高层住宅,对于这些既有高层住宅进行适宜的节能改造,可以使居住环境更舒适,还可以使住宅的使用周期变长,减少能源的消耗,从而使有限的资源实现可持续发展。在对国内外既有住宅建筑节能改造研究的总结与归纳基础上,针对沈阳市既有高层住宅外墙外保温现状,进行了调研分析,通过收集和研究数据,结合沈阳既有高层住宅的特殊性,对这类高层住宅常见的问题汇总,分析适宜的节能改造措施。最后,选择秀水街泰和苑小区高层住宅1#楼为示例,对采暖季室内温度偏低的原因进行分析,对比了现行的节能设计标准,综合考虑在不影响住户正常生活的情况下,提出一套适宜的外墙外保温节能改造方案,通过改造可显著改善外围护结构的保温性能,达到节能65%的设计标准。
[Abstract]:In 1970s, the energy crisis occurred. Since then, energy saving and emission reduction and sustainable development have become the world consensus concept of environmental protection, among which the development of building energy conservation is one of the hot topics of common concern. And in the construction industry is a very important issue. Building energy conservation includes new building energy conservation and energy conservation of existing buildings that do not meet the energy saving standard. In all kinds of buildings, there are a large number of existing residential buildings. And most of the initial housing construction did not take effective energy-saving measures, not up to the design standards of energy-saving, these housing envelope structure insulation, the performance of poor insulation, equipment is relatively backward. Therefore, it is an important part of energy-saving construction to transform the existing buildings that do not meet the energy-saving design standards. With the rapid development of high-rise housing, there are almost always many old high-rise residential buildings with high energy consumption, poor thermal insulation performance and poor comfort. For these existing high-rise housing for appropriate energy-saving transformation, can make the living environment more comfortable, but also can make the residential life cycle longer, reduce energy consumption. So that the limited resources to achieve sustainable development. On the basis of summing up and summing up the research on the energy-saving transformation of existing residential buildings at home and abroad, the external insulation status of existing high-rise residential buildings in Shenyang is investigated and analyzed. Through the collection and research data, combined with the particularity of the existing high-rise residential buildings in Shenyang, this paper summarizes the common problems of this kind of high-rise housing, and analyzes the appropriate energy-saving measures. Finally. Select Xiushui Street Taihe Yuan district high-rise residential building as an example, analyze the reasons of low indoor temperature in heating season, compare the current energy-saving design standards. Considering comprehensively that the normal life of residents is not affected, a set of suitable retrofit scheme of exterior wall heat preservation and energy saving is put forward, which can obviously improve the thermal insulation performance of exterior envelope structure. Meet the design standard of energy saving 65%.
