Status and decomposition analysis on building energy consumption of China in the last decade
As the need for international climate change negotiation and national sustainable development increases, China has announced its energy conservation and emission reduction target, in which building energy consumption is an important part. The energy consumption and total energy consumption of classified buildings in China during 2004–2013 are calculated, taking into consideration the characteristics of China's building sector. The LMDI (Logarithmic Mean Divisia Index) method is adopted to carry out the factor decomposition research and discussion of the four factors influencing the energy consumption (comprising different building types of GFA (gross floor area) per capita, the energy consumption per unit GFA, the urban population proportion, and the total population) of China's building sector. The results show that the continuous increase of GFA per capita is the primary factor influencing the increase in China's building energy consumption and the increase of urbanization ratio is the secondary factor. Meanwhile, controlling building energy consumption per unit GFA is the effective way to decrease the total energy consumption. The core method of controlling the energy consumption demands of China's building sector in the future is to reasonably control the future GFA per capita and to simultaneously take corresponding measures to reduce the building energy consumption per unit GFA.
