20th century, economic development, consume a lot of non-renewable resources ( oil, coal , etc. ) , resulting in a shortage of energy , the energy crisis has become a troubled world economy a big problem , energy conservation is imperative. Insight that only through energy-saving measures in order to reduce the continuing deterioration of the ecological environment of sustainable economic development issues and solve problems . The proportion of total energy consumption in the world , the construction energy consumption accounts for about 25% of the construction industry must address the problem of energy efficiency in buildings . Now more and more building take a different approach , different materials to ensure energy conservation and environmental protection. Ours is a populous country, is also a big country energy consumption per capita energy consumption is relatively high compared with developed countries , the proportion of energy consumption in residential buildings higher . With the continuous economic development, people's living standards continue to improve , residential building energy consumption rising to solve energy problems facing new challenges. Taiyuan continental climate is subtropical , with a certain amount of solar and wind energy resources. Shanxi coal province, due to the traditional coal as the main energy source , while ignoring the new energy development and utilization , residential building long-term dependence winter central heating, summer cooling , residential building energy-saving technology is relatively backward , facing energy crisis , energy saving imperative. Based on the characteristics and current residence Taiyuan climate comprehensive analysis of building energy consumption to the basic concepts of building energy efficiency as a starting point , referring to the current domestic and residential building energy technology application status, focusing on building envelope insulation, building construction natural ventilation and solar technology utilization, etc. , put forward for the living conditions of Taiyuan building energy conservation technology measures , the existing residential building energy-saving feasibility analysis and provide appropriate technical support .
