Energy efficient buildings in Qingdao, China

Abstract: At present, an important task for Chinese governments at all levels is to save energy and reduce pollutant emissions. The task of buildings energy efficiency accounts for 21% in the 12th Five Year Plan which from 2011 to 2015. With the development of social economy，the energy shortage is serious day by day．The energy-conservation of buildings is a high relevant issue in China．There are a large capacity and a wide range of existing buildings in Qingdao among which the overwhelming majority is the non-energy-efficient buildings and the operate energy consumption are enormous．At Present, according to the related statistic，the energy efficient building area only accounts for 3% to 5% of the total building area newly increased in our country every year, while in such existing buildings in Qingdao ，most of them are highly energy-consuming, the energy consumption in buildings is about 100-350 kWh for each floor area of the whole year，which is 2 to 3 times of the energy consumption of the same area of energy efficient buildings．So we can say that whether could we promote the effective use of resources and energy in buildings is very important，which will finally determine whether could we and take the road to sustainable development． In respect of the application of the complicated systematic scientific conclusions，the thesis carries out the analysis of geographic and climate characteristics in Qingdao area and the research of current energy consumption． Based on the quantitative model analysis of environmental and economic benefits of implementation of energy efficient buildings in Qingdao in scenario k, promotion and implementation of energy efficient buildings can substantially reduce the current high environmental cost associated with energy consumption for heating and cooling in buildings in Qingdao. Emission including carbon dioxides, sulfur oxide, nitrogen oxides and ash can be reduced, it means that under the scenario k energy efficient buildings has an idea performance on reducing pollutant gas. At the same time, companied by the great environmental benefits, there are also substantial economic benefits. Barriers to energy efficiency in buildings in Qingdao, including political, economic, social and technological barriers are discussed in this thesis. According to the investigation and analysis about the present situation and factors affecting the implementation of energy efficient buildings in Qingdao, this thesis put forward recommendations from the aspects of environment, politics, economy, society and technology to improving energy efficient buildings in Qingdao.
