Research on Impact Factor of Existing Residential Buildings Energy-efficient Retrofitting of North China

摘要

Since last year, when the energy-efficient retrofit for existing residential buildings was started in Northern areas of China, it has got great achievements in some provinces. But there exist obvious differences in the schedule of the work among the fifteen provinces. So we wanted to know how to eliminate the differences and find the policy instruments to push schedule for energy-efficient retrofitting to profitability. According to the problem, the investigation and survey situation of existing residential building energy efficiency retrofitting of part provinces and cities of North China is regarded as cut-in point of research, to propose the relation assumption among the impact factors of energy efficiency retrofitting mode, such as retrofitting principal, retrofitting content, retrofitting capital, and retrofitting effect, etc., the measurement index of each impact factor is regarded as variable, to establish the initial structural equation model. In this article, it utilizes the survey and research data of Tiaujin, Shanxi, Inner Mongolia, Shandong, and Ningxia, etc. in the early of 2009, to establish the structural equation modeling to research the impact factor to existing residential building energy efficiency retrofitting of North China.
