Our central government has put forward "We shall adhere to the guidelines of stressing both development and conservation but giving priority to the latter, and shall, in compliance with the reduction-based, re-utilization, resource-based principles, make great efforts to propel the conservation of energy, water, land and materials, strengthen comprehensive utilization of resources, adopt all-round clean production, improve a renewable resource recycling and utilization system, and form a low-cost, low-consumption, low-discharge and high-efficiency conservation-conscious way of growth."

These guides give us a clear concept of green buildings which features as water, land, energy and material saving and environment protection. Green build is defined as following: within building's life cycle, save resources in the utmost way and protect environment and reduce pollution at the same time.

Through green buildings have a lot of advantages, there are difficulties in its implementation. Therefore, we must build up a scientific development view and survey the influence to the environment in an all around way and make use of high technology to deal with the problems in a right way.

In green building development, we also should not ignore the economic effect. Environment protection and energy saving should be reasonably integrated with economy and adjust measures to local conditions for green building construction.
