Sustainability Study of a Residential Building near Subway Based on LCA-Emergy Method

In the context of ecological building and green popularity, sustainability assessment is becoming more important. this paper, a comprehensive evaluation platform by coupled LCA method energy was designed, verified, analyzed to assess system. The main results illustrated that construction stage most critical in terms emergy angle. From perspective, Emergy Sustainability Indicator at moderate level (1.0141), which can be considered increase proportion renewable reduce non-renewable resources improve degree. Of three scenarios second scenario has best unit value whole also shown demonstrate an individual. order verify accuracy data, sensitivity analysis conducted. Finally, two types positive measures are proposed ameliorate environmental system, containing increasing using recycled materials.
