Creating statistics for China's building energy consumption using an adapted energy balance sheet
(2019)
China's regular energy statistics does not include the building sector, and data on building energy demand is included in other types of energy consumption in the Energy Balance Sheet (EBS). Therefore data on building energy demand is not collected based on statistics, but rather calculated or estimated by various approaches in China. This study aims at developing and testing China's building energy statistics by applying an adapted EBS. The advantage of the adapted EBS is that statistical data is from the regular statistical system and no additional statistical efforts are needed. The research result shows that the adapted EBS can be included in China regular energy statistical system and can be standardized in a transparent way. Testing of the adapted EBS shows that China's building energy demand has shown an annual increase of 7.6% since 2001, and a lower contribution to the total energy demand as compared to the developed world. There is also a close link to lifestyle and living standard while industrial energy demand is mainly driven by economy and decoupling of building energy demand with increasing of building floor area, this is due to a considerable improvement of building energy efficiency. The adapted EBS creates a method for China conducting statistics of building energy consumption at the sector level in a uniform way and serves as the basis for any sound building energy efficiency policy decisions.
Energy service companies (ESCOs) play crucial role in building energy efficiency retrofit sector. However limited access to green financing has prevented ESCOs in their expansions in China. This paper, based on a survey of 469 samples and on-site visiting to and interviewing relevant 50 actors of ESCOs, financial institutions and local housing authorities, identifies main barriers of accessing to green financing at both systemic policy level and operational meso and micro level in China, and analyzes good practices at local level that overcome the barriers. The paper concludes that, although there are barriers existing at the policy level in China, substantial attentions and priorities should be given to take actions for overcoming the barriers existed at the operational meso and micro level. The paper suggests that the good practices of capacity building for ESCOs and local financial sector, intensifying participation of intermediate organizations or facilitators and diversifying financial sources and funding mechanisms and models that emerge from the local level should be disseminated in China.
