Abstract:
Based on analyzing the input of resource and the output of waste of material flow on the residential buildings in Beijing from 1990 to 2002, the material flow in 2010 was estimated. The current situation of material consumption of residential buildings in Beijing and the potential pressure to environment were revealed. The result shows that the direct material input is up to 72 537 kt/a, while the waste output is up to 41 378 kt/a. The material input and output per ten thousands production value keep balance after 1993. The energy consumption due to the construction and demolition activities of residential buildings accounts for 15% of the total energy consumed in Beijing, especially,the energy consumed by construction material production accounts for 89% of the total. Finally, by improving the manufacture techniques and the recycle use of the construction waste may reduce the energy consumption and promote the sustainable development of residential buildings.
