With the continuous development of economics, the energy consumption of buildings exhibits an annual increasing trend [1][2], which has received signifi cant attention from governments and relevant departments [3]. Some reports show that the energy consumption of heating in winter and cooling in summer has played a dominant role in the total energy consumption of buildings [4][5]. This energy consumption is subject to the considerable infl uence of climate change and enables potential energy savings [6]. Studies on building energy savings and climate change have important signifi cance in reducing terminal energy consumption and greenhouse gas emissions, which will be helpful to ensure the sustainable development of energy resources.Pol.

AbstractWe quantitatively evaluated the future energy consumption of offi ce buildings for cooling and heating in Harbin, Tianjin, Shanghai, and Guangzhou, which represented different building climate zones in China. The results show that offi ce buildings in different building climate zones have a decreasing trend of heating load and an increasing trend of cooling load. For the change of heating load, the fastest decreasing rate is in Harbin, located in a severe cold zone with 32.9 and 81.5 W/m 2 per 10 years for low and medium forcing, respectively, followed by Shanghai, located in a hot summer and cold winter zone, and Tianjin, located in the cold zone. For the change of cooling load, the fastest increasing rate is in Shanghai, with 76.3 and 124.0 W/m 2 per 10 years for low and medium forcing, respectively, followed by Guangzhou, located in a hot summer and warm winter zone. By contrast, the increasing rate for the cooling load is relatively slow in Harbin and Tianjin. By comparing with the past 50 years , total energy consumption in Harbin will decrease in the future during two periods (2011-50 and 2011-2100), with 1.93% and 1.85% reduction in 2011-50 for low and medium forcing, and 2.16% and 2.72% reduction in 2011-2100, respectively.
