Office buildings and large Public buildings The phenomenon of large energy consumption, low energy consumption efficiency and unreasonable operation management is common. Most buildings in rural areas have not taken thermal insulation measures. Compared with the western developed countries, China's building energy efficiency standards still have a certain gap in key energy efficiency indicators. Due to the advanced materials, products and technologies, the energy efficiency of housing construction in the western developed countries is higher than the current situation in China.
The main characteristics of building energy consumption in China are: first, the total amount of building energy consumption continues to grow rapidly. The main reasons are as follows: First, the urbanization process is accelerating. Every year, a large number of new buildings are added in cities and towns, resulting in rapid energy consumption growth. Second, with the improvement of people's living standards, the use of various household appliances has increased significantly, and the energy consumption per unit building area has increased rapidly. Third, the improvement of urban and rural residents' requirements for indoor comfort of buildings has led to rapid growth of energy consumption.
Second, building energy use in rural areas increased significantly. In 2007, the per capita commodity consumption in rural areas was about 1.8 times that in 2000. Third, building energy efficiency is generally low. At present, China generally implements the standard of 50% energy saving. Even if the standard of 65% energy saving is implemented, the heat consumption index is more than 50% higher than the average level of developed countries under the same climate conditions.
