【摘要】 自工业文明以来，全球气候持续变化，且在不同时期的变化规律也不尽相同，近年来全球气候变化呈现加剧态势。室外环境是影响建筑能耗的关键因素，在全球气候变化加剧的背景下，准确分析气候变化对建筑冷热负荷的影响对办公建筑节能低碳技术的发展与应用具有重要意义。选取10个位于中国不同气候区的城市，基于各城市1960—2014年(西安市为1960—2013年)的真实历史气象数据，以及2种典型浓度路径(RCP)(即高水平RCP 8.5和中等水平RCP 4.5)下的未来气象预测数据，采用建筑能耗模拟软件和回归分析方法探究气候变化对不同气候区办公建筑能耗的影响。结果表明受到气候变化的影响，不同城市的建筑冷热负荷变化为40%～400%,在未来建筑和暖通空调系统设计时应更加关注气候变化及其对建筑能耗的潜在影响。更多还原

【Abstract】 Global climate has been changing continuously since industrial civilization, and the variation varies in different periods. In recent years, global climate changes rapidly. Since the outdoor environment is a key factor affecting building energy consumption, it is important to accurately analyze the impact of climate change on building cooling and heating loads for the development and application of energy-saving and low-carbon technologies in office buildings in face of rapid global climate change. Ten cities located in different climate zones in China are selected, and based on the real historical meteorological data of each city from 1960—2014(1960—2013 for Xi’an) and the future meteorological prediction data under two representative concentration paths(RCP)(i.e., high level RCP 8.5 and medium level RCP 4.5), building energy simulation software and regression analysis are used to explore the impact of climate change on building energy consumption. The results show that the energy consumption of office buildings in different climate zones is affected by climate change, and that the building cooling and heating loads vary from 40% to 400%, which should be paid more attention to climate change and its potential impact on building energy consumption in future buildings and HVAC systems design.更多还原
