随着经济的发展,我国的能源形势越来越严峻,而在所有的能耗种类中,建筑能耗占能源终端能耗的30%左右。在国家和地方政策和资金支持下,各地既有居住建筑节能改造积极推进,以山东省日照市沿海某住宅小区的多层住宅建筑节能改造情况进行分析研究,归纳总结改造施工的经验与不足,通过对改造前后四年建筑供暖能耗数据经济性分析和节能评估,得出对既有建筑节能改造既能带来的经济效益明显又能取得良好的社会效益,为我国今后既有建筑节能改造工程提供一定的技术支持和经验借鉴。
With economic development, the energy situation in our country is getting more and more severe. Among all types of energy consumption, building energy consumption accounts for about 30% of energy end-use energy consumption. With the support of national and local policies and funds, the energy-saving renovation of existing residential buildings in all localities has been actively promoted. The energy-saving renovation of multi-storey residential buildings along a residential area along the coast of Rizhao, Shandong Province has been analyzed and summarized, and the experiences and deficiencies in reconstruction construction have been summarized and summarized. Through the economic analysis and energy-saving evaluation of building energy consumption data before and after the renovation four years ago, it is concluded that both the economic benefits and the good social benefits brought by the retrofit of existing building energy-saving can be obtained. Engineering to provide some technical support and experience to learn from.
