| Summary/Abstract |
Distributed energy (DE) is receiving lots of attention from the Chinese government. A number of DE projects have been constructed in China. However, there are still numerous problems with DE projects. What hinders the development of DE in China? The Huadian Jimei distributed energy project (HJDE) is a typical DE building project that was not completed successfully. This paper focuses on this DE project to explore the barriers to DE development. The research group conducted 13 semi-structured interviews with representatives of institutions and corporations involved in the HJDE project to collect information. Based on the information, three types of problems were determined, and the results indicate that these conflicts between the core stakeholders make DE projects unsuccessful. These problems result from institutional barriers to DE, rooting in the development policy and the current energy market. Moreover, several key stakeholders are not able to play an active role in the design or management of DE projects. The Chinese government will put a much greater effort into the development of future DE projects. Many national support policies and rules will be announced, which are easy to practical use. Under these conditions, 1000 DE projects will be successfully completed until 2015.

| Summary/Abstract |
The building energy efficiency labeling (BEEL) scheme has been adopted in China since 2008. However, until now, its effect on the actual building energy efficiency has not been accurately established. The objective of this study was to investigate this effect through a case study in Shanghai, China. Additionally, by performing a thorough review, potential barriers for implementing the BEEL scheme in major areas of China were analyzed. The results indicated that 1) the energy use intensity of labeled commercial office buildings in Shanghai followed a normal distribution, with an average value of 79.14 kWh/(m2a); 2) the energy-saving rate and energy consumption exhibited an inversely proportional relationship for residential buildings, but this relationship was not applicable for commercial office buildings; 3) for Shanghai, ground source heat pumps (GSHPs) and variable refrigerant volume systems are more appropriate for commercial office buildings, and GSHPs and split air conditioners are more useful for residential buildings. The potential barriers were classified into three main categories—technical, political, and awareness—and corresponding solutions were proposed. The authors hope that this study can promote the adoption of the BEEL scheme in China.
