The effect of climate change on building heating and cooling energy demand in China

Climate has a key impact on building energy efficiency. The of climate change heating and cooling degree-days China during the past 60 years was studied in this paper. meteorological data 613 cities published by National Center applied research. study results showed that spatial distribution characteristics is obvious. area with HDD18 °C over 2000 d·°C dramatic shrunk recent 30 compared period from 1964 to 1983, while CDD26 90 expanded years. each city inhomogeneity. decrease mainly occurred north northwest China, increase southeast China. outcomes paper may provide theoretical basis for efficiency design future.
