A Quantitative Study on Carbon Emission Features of Residential Building in Shenyang Based on LCP Theory

摘要

As the largest amount of building in urban architecture, residential building brings enormous greenhouse gases emissions concerning energy and resource consumption and solid waste disposal during its construction and removal. On the basis of LCP theory, the carbon emission of a residential building in Shenyang was calculated in each stage of the life cycle. The calculation shows that the carbon emission in the use and maintenance stage accounts for 86%, the biggest proportion in its life cycle. The carbon emission of one square meter reaches 45.27kgCO2/(m~2·y), higher than other cities in China. So the potential for Shenyang to save energy and reduce carbon is considerable. The low carbon objective can be achieved through reducing the use of fossil energy, improving resident's energy saving awareness in the use stage and enforcing energy efficiency policies and measures. Meanwhile, from the perspective of research methodology, the carbon emission of a building is regionally featured. For instance, electric carbon emission coefficient is substantially influenced by local energy structure; the distance between building material production and transportation in different places is different; the carbon emission caused by the energy consumption during the usage of the building is closely associated with local energy saving policies and regulations.
