Research On Carbon Emission Reduction Strategies Of Building Based On Life Cycle Assessment

With the rapid development of human society, the problem of the energy shortage and environmental deterioration have become increasingly prominent. As the basic behavior of the humanity transformed the nature, the architectural products made by construction activity are the main energy and resource consumers, and also the major emitters of environmental pollution, construction put enormous pressure on resources and environment. With the rapid progress of urbanization, energy dissipation and carbon emissions in building would be quickly increase, how to ensure promote the construction on growth that is healthier and sustainable while reducing carbon emissions by building materials manufacture and building energy consumption, are likely to be priorities.Through the studying and understanding of Life Cycle Assessment, the article takes the qualitative approach and quantitative analysis, based on LCA’s technical framework to carry out systematic research on carbon emission activities during the whole life of the building process that include raw materials mining and processing, the construction, operations management and dismantling, builds up evaluation system of the life-cycle environmental impact of the building, introduces carbon emission calculation method, takes DaShan placement housing in Qingdao city as the case applying the pattern to it. analyze the great stage and factor environmental impact of building’s whole life. According to the information of the life assessment analysis and life cycle impact assessment, propose carbon reduction countermeasures pointedly to every stage of building, it can provide the theory basis for energy conservation and emissions reduction of engineering projects, the path selection of low carbon buildings and the policy-making more scientific.
