A Sustainability Analysis Based on the LCA–Emergy–Carbon Emission Approach in the Building System

Ecologically sustainable buildings and their carbon emissions are two popular ideas for building life cycle systems. It is a challenge to comprehensively assess the sustainability of cases using different methods. Based on over decade research, this paper attempts explore possibility quantitatively integrating both approaches. In study, we adopted emergy method emission approach analyze system. particular, similarities differences have been identified through at each stage building’s whole cycle. The results demonstrate that operation phase critical contributor (Approximately 79.6% total 97.9% entire emission), which occupies most amounts order improve ecological system, renewable energy subsystems considered explored. While overall system enhanced, new systems will aggrandize emissions. Therefore, should be comprehensively, relationship between views needs balanced.
