A Research on the Evaluation Framework of Carbon Footprint in Large-scale Public Building

The purpose of this study is to evaluate the quantification of carbon footprint over the full life cycle of a large public building by establishing the framework of carbon footprint evaluation system. The theoretical basis of the framework is the life cycle theory, the gray system theory and the analytic hierarchy process. A quantity of real data should be collected by questionnaire, site survey scene and consulting of specialist and pretreated through unit conversion to take the associated data set as a class to deal with. The universality and peculiarity of carbon footprint in large-scale public building should be concluded on the basis of a great number of effective data. The quantitative analysis method should be used to confirm different weighting coefficients, the gray relational degrees of carbon footprint and its influencing factors in large public building. The theoretical analysis showed that the evaluate system is applicable to large public buildings of various kinds, and quality of comprehensive evaluation with this system shall be good. Carbon footprint analysis of large public buildings contributes to the allocation of limited resources for reducing regional greenhouse gas emissions.
