Development goals, main work subjects and guarantee measures for energy conservation work of civil buildings in Beijing are formulated by Energy Conservation Plan for Civil Buildings in Beijing during the 12th Five-Year Plan Period issued in 2011. With important change in work situation of building energy conservation, the demand on thought of building energy efficiency during 13th Five-Year plan is increased increasingly, the potential study on building energy conservation until 2020 is required to be developed urgently in order to provide the reference for further establishing medium and long-term building energy conservation plan. Administrative Provisions on Building Energy Efficiency in Beijing issued in 2001 is a basic legal basis for developing the building energy efficiency work in this city over decade years. However, with development of building energy efficiency work, it is required to be revised for guiding the practical work. Promoting the green buildings is an important work for building energy conservation in our city. 35 million m² promotion objective in 12th Five-Year Plan about building energy efficiency is proposed, the work subject s, management policy, supporting measures and other system and mechanism are of ambiguity except for laws and regulations. So it is necessary to develop the survey work and sort up relevant policy and thinkings. 

In conclusion, this project is proposed to launch the study from three aspects——Sub-Subject I: Study on Energy Consumption Situation and Medium and Lon- term Energy Conservation Potential of Civil Buildings in Beijing, Sub--Subject II: Revise for <Administrative Provisions on Building Energy Efficiency in Beijing > and Sub—Subject III: Study on Present Situation Green Building System and Mechanism and Promotion Policy in Beijing.
