基于PEST—SWOT的既有居住建筑绿色改造研究

我国既有居住建筑存量大,建筑性能落后,在使用过程中会消耗大量能源,而新建绿色建筑消耗资金大,见效慢,既有居住建筑绿色改造是国家解决资源消耗、可持续发展的关键。基于PEST—SWOT分析模型,从四个层面分析既有居住建筑绿色改造的优势、劣势、机会和威胁,提出在政策层面建议完善法律法规、细化评价标准、能效标识;经济层面建议合理拆改、加大激励力度;社会层面应将老旧小区改造项目清单透明化等,技术层面开发绿色技术、培养绿色改造人才的建议。

A Research on the Green Renovation of Existing Residential Buildings Based on PEST-SWOT

There are a large amount of existing residential buildings with backward architectual functions in China, which has resulted in too much energy consumption. Meanwhile, it will take huge investment and long periods of time to build new green buildings. Therefore, the renovation of existing residential buildings is the key to solve the probelem of resource consumption and sustainable development in China. Based on PEST-SWOT analysis model, this paper, focusing on four aspects, has analyzed the advantages, disadvantages, opportunities, and challenges in the green renovation of existing residential buildings. Accordingly, some suggestions have been put forward in this paper. First of all, relevant laws and regulations are supposed to be improved; the assessment standards and energy-efficiency labelling should be further refined. Secondly, it is suggested to promote the rational renovation and strengthen the motivation measures. Besides, the list of renovation projects are ought to be open and transparent to the public. Finally, it is of great necessity to develop green technology and cultivate talents in the area of green renovation.
