In the manufacturing stage, such primary processes as polycarbonate molding and surface painting are included, whereas different surface finishing technologies like normal painting, electroplate, IMD and VDM etc. were assessed. The results showed that housing decoration plays a significant role within the housing life cycle. The most significant environmental impact from housing production is the photochemical ozone formation potential. Environmental impacts of different decoration techniques varied widely, for example, the electroplating technique is more environmentally friendly than VDM. VDM consumes much more energy and raw material. In addition, the results of two alternative scenarios of dematerialization showed that material flow analysis and assessment is very important and valuable in selecting an environmentally friendly process.展开更多

Specifically, the empirical study analyzes the HSI of low-priced housing in Beijing. The results show that the HSI model is valid and the customer satisfaction theory can effectively analyze the housing industry. The results can help illustrate the factors which most affect customer satisfaction, and can be used to not only enhance the quality of homes and promote the housing market, but also to improve the standard of living for lower income people and provide suggestions to policy makers.展开更多
