It has a great achievement on new building energy efficiency, existing building energy reform, renewable energy application and green building promotion.However,there is a significant short board at building energy efficiency data quantification of this fundamental work and there is no authority data about Chinas building energy consumption.In the stage of total carbon emission control,lack of building energy consumption data put a limit on the development of Chinas building energy efficiency. This project aims to define the boundary for embodied energy in buildings and boundary for energy statistics,and makes a comparative analysis of the advantages and disadvantages of various measurement methods, from the prospect of analysis the reasons for the differences in building energy consumption data of different institutions.By combing and analyzing statistical indexes , this project suggests calculation method of building energy consumption and floor area based on Statistical yearbook. Based on this, the energy consumption data of buildings in China from 2001 to 2014 are calculated and analyzed, and some suggestions are put forward to consolidate the data base of building energy consumption in China.The main conclusions are as follows. (1) the reason for differences in building energy consumption data.the building energy consumption account for 15%50% of the total energy consumption.there are three reasons for the differences.One is the boundary for building energy consumption.building energy consumption is defined as the operation energy consumption of buildings,however,operational energy constitutes a relatively larger proportion of a buildings total life cycle energy,such as implentment and building materials. Two is boundary for energy statistics. The result of using power generation coal consumption coefficient is double than using electric equivalent method.in addition,whether the inclusion of rural biomass will also bring large differences.The finally one is calculation method.the calculation method of building method including :statistical yearbook method,energy efficiency method and end-use energy model.there is a big difference between different methods and data sources. (2) Problems and treatment methods of building area index inStatistical VI Yearbook. The main problems include: time series data is not complete, statistical definition changes, some index data is lacking. The data processing methods of building area based on the statistical yearbook are: 1) Rural building area, which is calculated by the rural population and per capita living building area; 2) Urban living construction area, the data of 2001-2006 are based on the actual living building area at the
