Study On Comprehensive Evaluation Model Of Green Residential Building In Urumqi

At present, Urumqi is facing a serious ecological and environmental pressure, while the construction industry is one of the most critical influences in ecological environment. Therefore, the government has high expectations of the development of green building in Urumqi, who puts forward a series of related development policies and suggestions. And the government has already decided to enforce the green building criterion in four kinds of public buildings(including the office buildings, public buildings, affordable housing and large public buildings) at the beginning of the 2015. But at the same time, Urumqi lacks the green building assessment system that fit to the local building culture characteristics. And the residential building plays an important role in the development of construction industry in Urumqi, which has become one of the most important industries in the local economy. In this paper, we proposed a suitable comprehensive assessment model of green residential buildings in Urumqi.Firstly, according to the development of domestic and international research about green building assessment system, and combining with the local characteristics, taking the old and new version of "evaluation standard for green building" as the guidance, we propose a comprehensive evaluation index system of green residential and final evaluation standard in Urumqi.Secondly, after analyzing the problems in the existing evaluation standard evaluation methods, and the advantages and disadvantages of each existing evaluation method, we establish a comprehensive evaluation method for green building. The method determines the index weight by the improved AHP method, and using the CFTOOL toolbox in MATLAB to get the value of quantitative indicators, and the expert evaluation method to achieve the qualitative index value, and the comprehensive evaluation of grey clustering method to get the level of residential green.Finally, we take the 2# residential building of XiuCheng District in Urumqi as the evaluation object, using our evaluation model to evaluate it, get its green level, and analyzing the evaluation results. At last, we proposed some improvement measures.
