| 摘 要： | 利用能耗模拟软件（TRNSYS）模拟了1971—2010年天津市办公建筑制冷和采暖能耗，结合未来不同排放情景（低排放：B1；中等排放：A1B）下气候预估数据，定量评估了未来（2011—2100年）气候变化对办公建筑能耗的影响。结果表明，2011—2100年热负荷呈显著的下降趋势，而冷负荷显著上升，冷负荷的上升幅度高于热负荷的下降，导致总能耗呈微弱的上升趋势；低排放情景下热负荷的下降和冷负荷的上升幅度低于中等排放情景，总能耗的变化在两种排放情景下没有明显差异；与1971—2010年相比，低排放和中等排放两种情景下2011—2050年热负荷下降10%左右，而冷负荷上升约12%，总能耗增加超过2%；2051—2100年热负荷的下降和冷负荷的上升更为明显，尤其是冷负荷上升（约30%），总能耗增加8%左右，冷负荷变化率在两种情景下相差较大。

| Abstract: | Cooling and heating energy consumption of office building during 1971-2010 was simulated by using energy consumption simulation software (TRNSYS). By combining climate projection data under two emission scenarios (low emission: B1; medium emission: A1B), the impact of climate change on office building energy consumption during 2011-2100 was assessed. The results show that heating load of office building significantly decrease in the next 90 years but increase of cooling load is found. The increase rate of cooling load is higher than the decrease rate of heating load, resulting in the weak increase of total energy consumption. Under the B1 scenario, the rates of decrease in heating load and increase in cooling are less apparent compared with the A1B scenario. The change rate of total energy consumption is not apparently different between the two scenarios. Compared with 1971-2010, the average multiannual energy loads of office building in 2011-2050 are about 10% less for heating, about 12% more for cooling and over 2% more for total energy consumption under the B1 and A1B scenarios. The decrease of heating load and increase of cooling load are more apparent in 2051-2100. Particularly, the cooling load and total energy consumption will increase by about 30% and 8%, respectively. Large difference in the change rate between the two scenarios in 2051-2100 is found in the cooling load. |
