Decomposition Analysis of Driving Factors for Building Energy Consumption in China

摘要

This paper offers a model for analyzing the factors affecting building energy consumption based on qualitative analysis. Logarithmic Mean Divisia Index (LMDI) method is used to decompose the driving factors causing China's building energy consumption change during 2005-2009. It is concluded that improvement of people's living condition and the increment of building area significantly lead to increase of energy consumption. Although the effect is relatively small, population and urbanization devote to energy consumption as well, while improvement of building efficiency is slow for the growth of energy consumption. From year 2005 to year 2009, energy saving of 121 million tons of standard coal, has been achieved by improving building energy efficiency. It decreases building energy consumption by 23%. Building energy efficiency played an important role in protecting the environment.
