Residential Environment Evaluation System Considering Environmental Quality And Environmental Load For Sustainable Development Of Residential District

Residential environment is one of the most important elements for quality of life, as well as the main support for the activities of economy, culture and society. On the other hand, the improvement of residential environment quality also has been increasing the consumption of energy and emission of pollution. In this paper, firstly, we established a systematic methodology for the evaluation of sustainable residential environment, considering both residential environmental quality (Q) and residential environmental load (L). The part of Q is constructed by safety, healthy, amenity, convenience and community of residential environment. The part of L is about the environmental impact of the lifecycle of the housing and community. Then, we selected HuZhou city which is in the center of Changjiang Delta Region of China as our research area. In first part of the research, we performed questionnaire surveys in three residence we selected in HuZhou focusing on the residential environmental quality (Q). We analyzed the residential environmental satisfaction of people. Then, for the part of residential environmental load (L), we consulted experts who comes from different areas in Architecture industry, determined the weight through AHP, and got the result through software simulation, data measurement and verification of the drawings. Together with the residential environmental quality (Q) and residential environmental load (L), we got the result of residential environmental evaluation finally. Compared to the existing similar studies, the innovations of this study are as follows: 1. Different spacical criterion. Most of the evaluation systems are in the construction level, but this study stand in the district level covering the city, rather than building level. 2. Different appraisals. In the existing evaluation system, only experts can be appraisals, however in our study the both the residents and experts can be appraisals. Environmental quality is evaluated by the users, and environmental load evaluated by experts. 3. Different weights. In this study the weight of environmental load which is non-fixed is calculated by AHP. So in different region we can have different weight Suitable for the local environment. 4. Different evaluation ways. In this study, we combined qualitative and quantitative evaluation methods together. In the evaluation of environmental quality, we used the qualitative assessment; In the evaluation of environmental load, we used the quantitative evaluation methods such as software simulation, data measurement and verification of the drawings. Finally, we hope the results of our study can contribute to the sustainable development and improvement of urban residential environment for rapidly developing China.
