This paper aims to investigate the implication of present and future bioclimatic potential of passive heating and cooling design strategies for climate change scenarios of five locations covering all climate zones of India. Weather data for future climate change were developed for A2 (medium-high) scenario of the Intergovernmental Panel on Climate Change (IPCC) for four time slices, namely TMY (Typical Meteorological Year), 2020, 2050 and 2080. A case study residential building was used for calibration and validation of the bioclimatic potential using EnergyPlus simulation. Results show a strong correlation between the annual bioclimatic summer and winter discomfort hours and the corresponding annual cooling and heating energy load for the changing climate scenarios. Results also show an overall increase in annual cooling energy load, over and above the base case, ranging from 18% to 89% among the five cities in 2020; 32% to 132% in 2050 and 58% to 184% in 2080 if residential buildings continue to be operated in the same manner as it is done today without passive strategies. The use of passive strategies may reduce the annual cooling load by about 50%– 60% in residential buildings in future.

本文旨在研究被动加热和冷却设计策略的当前和未来生物气候潜力对涵盖印度所有气候区的五个地区的气候变化情景的影响。针对政府间气候变化专门委员会（IPCC）的A2（中高）情景，针对四个时间段（即TMY（典型气象年），2020年，2050年和2080年）开发了用于未来气候变化的天气数据。使用EnergyPlus模拟软件对生物气候潜力进行校准和验证。结果显示，在不断变化的气候情景下，夏季和冬季的年度生物气候不适时间与相应的年度制冷和供暖能源负荷之间存在很强的相关性。结果还显示，年度冷却能源负荷总体增加，超过基本情况，到2020年五个城市中从18％到89％不等; 如果住宅建筑继续以与今天相同的方式运营，而无需采取被动策略，则到2050年将达到32％至132％，到2080年将达到58％至184％。被动策略的使用可能会在将来使住宅建筑的年度制冷负荷减少约50％至60％。
