The Comparison Of Green (Sustainable) Building Evaluation Standard In China, Britain And United States

The building sector is the main emission source of green house gases.Under the background of global climate change, it is imperative to develop green building. In order to promote the development of green building effectively, in addition to the development of relevant building energy efficiency standards, policies, many countries from the aspects of energy conservation, efficient use of resources and protecting environment, drafted "green building rating standards"to evaluate buildings from aspects of conserving energy,land, water, materials and environmental protection, and evaluate the overall green performance of buildings.This paper summarized the current situation of energy development of the construction sector in diffent countries to underline the importance and necessity of construction sector energy conservation. In addition,based on the existing building energy efficiency standards and green building rating standards, the U.S. LEED-NC, the United Kingdom "Sustainable housing standards" and Chinese "Green building rating standards" are selected to make comparision from five aspects of conserving energy,land, water, materials and indoor environment,concluding that there was large room for improvement of chinese green building rating system in the coverage and the accuracy of measurement indicators.Finally, to further reflect the differences of the three evaluation systems, this paper choose Visual Basic 2006 as a development platform, developed a compa rison evaluation system for green building CASGB (Assessment System for Gree n Building). The software contains three country's green building assessment stan dards, it can make assessment for buildings with the three standards.A real resid ential building is used to demonstrate the applicability of the systems.
