Statistics show that China s current building energy consumption accounts for about 30% of total energy consumption, construction in the total carbon dioxide emissions accounted for almost 50% of the building energy saving has been imminent.
China is currently the world s largest construction in the world last year, about 2000000000 square meters of new buildings consume about 40% of the world s cement and steel. It is reported that the average life expectancy in Europe and the United States countries (regions) in 80 years, while the average life expectancy of Chinese architecture is only 50 years. In the construction tide of like a raging fire, the construction "short-lived" emerge in endlessly, a large number of "young" architecture forced "untimely death". People are showing off their GDP at the same time not to realize that more and more of the construction waste to the community, to the descendants of the disaster.
The good is, the development of green building has been explicitly written into the national "12th Five Year" plan. 2012 "government work report" pointed out that the promotion of industrial structure optimization and upgrading to develop high-end equipment manufacturing, energy saving, environmental protection, new materials and other industries. We will increase funding for technological upgrading projects, and press ahead with the transformation and upgrading of traditional industries. "Government work report" mentioned in the key energy saving and emission reduction is to save energy, improve energy efficiency, reduce pollution. We will promptly formulate and promulgate a work plan for appropriately controlling total energy consumption, and move quickly to base the energy pricing system on the market. Comprehensive use of economic, legal and necessary administrative means, highlighting the focus on key areas of industrial, transportation, construction, public institutions, residents living and 1000 key energy consuming enterprises energy saving and emission reduction, and further eliminate backward production capacity.
In July 2011, the Ministry of housing and urban and Rural Construction issued the development of the construction industry "1025" planning ", planning requirements, the construction process of building products unit added value of energy consumption decreased by 10%, increase the proportion of steel structure engineering; new construction engineering design accord with national building energy efficiency standards to achieve 100%, the new project construction conforms to the national building energy saving standard. Planning requirements improve building structure parts of the industrialized manufacturing level, promote the structure of integrated, modular production; encourage and promote new affordable housing and commercial housing menu style decoration others. The introduction of the relevant policies have been fully demonstrated that the state, housing and urban and rural construction in the building energy efficiency.
