Yunhui Yang Associate Professor of Construction Engineering Department, Kunming Metallurgy College,Kunming, 650033, China Keywords:Green building, Rating System, Development Abstract.China has the biggest building construction market in the world today and it is growing at an explosive rate.
So far, Chinese government invested heavily in the construction of the demonstration projects, as all the additional cost of green buildings is usually borne by Chinese government funding awarded to demonstration projects, such as the Office Building of Green Building Engineering Research Center of Shanghai in 2004, and Shanghai historic protection building Wenyuan Building in Tongji University in 2007.15 In 2008, the State Council put forward to organize the implementation of 30 energy-efficient green building demonstration projects.
With huge differences of climate as well as energy consumption characteristics between northern and southern China, China is divided into five main climatic zones; the division set given by the “Code for thermal design of civil buildings GB50176-93” [MOC 1993]: severe cold, cold, mild (temperate), hot summer and cold winter, and hot summer and warm winter.
China also lacks green building technology and knowhow, namely, lack of expertise of integrated sustainable building design and construction among engineers, designers and constructors.
