42. Chinese Building Energy Service Industry Evolution Based on Ecological Niche

Energy conservation has become a worldwide issue recent years. In order to improve the energy efficiency of existing building, ESCOs provide a package of techniques and funding support. Building energy service industry has developed rapidly in the past decades in China. However, there are still many problems hampering the implementation of building energy efficiency projects, leaving huge potential for the improvement of building energy service industry. From the perspective of ecological theory, building energy service industry can be treated as an ecosystem which contains producer, consumer, decomposer and environment. To reflect the situation of building energy service industry, six indicators are selected namely “ecostate indicator” and “ecorole indicator”. For an intimate presentation, the development of GDP is chosen to be a reference. By comparing the building energy service industry niche with GDP-niche, it is found that although building energy service industry is developing rapidly because of the policies and financial support, it lags far behind GDP development.
