Exergy assessment of building energy use in China's hot summer and cold winter climate zone

BEU accounting and assessment is a fundamental task for development of energy efficiency in buildings. The traditional methodology is based on caloric value of energy carriers, which is only relates to energy quantity. To address a comprehensive assessment, an exergy assessment methodology is put forward in this paper. Furthermore, in existing China's statistical yearbook, there is no specific item for building energy use. This paper processes analysis for statistical yearbook and acquires relevant rough data of building energy use.
