The Old Residential Building Performance Evaluation Index System

Today the conflict between development and the scarcity of resources, energy crisis, environmental damage and other multiple problems deepened, in pursuit of a better and more stable development, the country put forward sustainable policies, to make the economic development and environmental protection coordinated. The statistics of building energy consumption has accounted for 46% of total energy consumption, and there is no energy-saving measures for old residential; at that time, the design level is limited, using energy of the building itself in the process is even more than today’s green building new residential projects. Therefore, the large quantities of old residential resources exist today which can continue to use, is neither to removal blind nor let it aging, relevant evaluation system that needed to be found to evaluate, to found major flaws,to determine urgency of the transformation and the to offer transformation of the standard, so that the reform can be more scientific and objective."Old Residential Building Performance Evaluation Index System", which is sub-topic content of "the old house performance evaluation and practical utility of research(51378329)" is National Natural Science Foundation of China. the overall performance of the old residential in project summarized in three areas: building performance, structural performance and device performance. This article aims to build evaluation index system for the building of the old residential properties in North China, the performance of the residential building is divided into indoor function space and outdoor environment and planning aspects.Old residential building performance evaluation index system including three parts, that is the evaluation index system, evaluation criteria and evaluation rules and application of. Through six chapters be discussed, namely:Chapter one. Introduction. Topic, significance of research, scope and subjects of research methods and ideas are clearly stated.Chapter two. Review of the old residential building performance evaluation index system of domestic and foreign. Mature presentation and comparative indicators index system referenced in domestic and foreign.Chapter three. The old residential area in North elaborate performance issues. Analyze the geographical and climate characteristics in north China; Through research summarizes the overall situation in north China, in view of the existing problems were analyzed, and the problem can be divided into residential environment and planning, function and space two aspects, each aspect is divided into three class, technical, economic and social problems.Chapter four. Old residential building performance evaluation index system in north china construction. This chapter is the focus of this article. To establish old residential building performance evaluation system in north china, by domestic and foreign building performance evaluation, the current specification standards to the relevant literature for reference, understanding of the north china regional characteristics and the existing residential problems which are summaried based on the evaluation of the qualitative and quantitative analysis, the use of expert investigation scoring method calculated by weighting the data, and finally through the final set score level evaluation to obtain the results.Chapter five. The evaluation index system and methods described herein by way of example constructed empirical applications.Chapter six. Conclusion. Summarizes the research results and shortcomings of this paper, the development and future research directions is discussed.By research on performance problems of old housing constructions and the evaluation methodology, the paper provided a quantitative basis and reconstruction basis for designers and constructors in specific reconstruction projects. At the same time, the paper provided a standard of nationwide large-scale reconstruction of old housing buildings for reference, so as to make a contribution to the city development.
