为研究夏热冬暖地区居住建筑应对气候变化的适应性，运用TRNSYS动态能耗模拟软件对该地区典型居住建筑能耗进行仿真，制定了居住建筑节能星级评估体系。以广州市为例，分析预测了广州2020年、2050年及2080年的气候变化，并提出应对气候变化的节能措施。研究表明：气温上升1℃，4.0、5.5及6.5星级建筑能耗将分别增长25%、20%及20%；在2080年，气温上升近3.5℃，4.0星级建筑CO2年排放量达53 t/m2，将4.0星建筑升级到5.5和6.5星级，每年可相应减排19.5 t/m2和23.2 t/m2；若以4.0星级建筑当前的CO2排放量为控制目标，则需把建筑围护结构热工性能提升到6.5星级水平，可以实现未来70年减排45%。

In order to investigate the climate change adaptation pathways for residential buildings in hot summer warm winter zone in China, the building energy consumption rating schemes in this area were built based on the dynamic thermal performance of residential buildings by using TRNSYS software. The future climate change of Guangzhou in 2020s, 2050s and 2080s was analyzed, and then adaptation pathways were put forward. The results showed that an increase of 1 oC in global warming will induce the energy consumptions of 4.0, 5.5 and 6.5-star buildings by 25%, 20% and 20%, respectively. And if an increase of 3.5oC comes true in 2080s, annual CO2 emission of the 4.0-star building will reach 53 t/m2. However, if we retrofit and update the building to 5.5 or 6.5-star, 19.5 or 23.2 t/m2 reduction of CO2 emission can be obtained accordingly. Moreover, 45% reduction of CO2 emission in the future 70 years is available if the envelopes of current buildings can be retrofitted to 6.5-star.
