| With China's rapid economic development and rising living standards, China's energy consumption have grown very rapidly, so energy resources have become the bottleneck of economic and social sustainable development. Therefore, our government attaches great importance to energy-saving and set the goal of decreasing energy consumption per unit of GDP by 20% at'The Eleventh Five-Year"period unit. Building can be one of the three major end-use areas, and China is in rapid development period of the construction industry, building energy consumption is growing, so building energy efficiency has become the most important of the current energy conservation. Experience from developed countries show public participation can greatly contribute to the development of energy conservation in construction. Actually the concept of public participation was introduced into China in the early 1990s, but public participation mechanisms are still not sound.Selecting Xian as a typical case, this paper mainly explores the status quo of public participation in energy-saving from angles of public participation awareness, ability and channels of building energy efficiency with the goal of improvement of energy efficiency ,with the assistance of basic western theories and approaches on public management , sociology, economics , in addition , with experience from developed countries in the process of building public participation on energy-saving. It attaches great importance to the role of NGO organizations play in building energy -saving and the exploring of public participation problems in building energy-saving to attract government's attention to the importance of public participation , then create a good building energy efficiency incentive mechanism to improve public participation in the field of energy saving .Results of this study will contribute to the improving of the public participation awareness and capacity and broadening participation channels. |
