Developed under the framework of “Annex 80: Resilient Cooling of Buildings” project by the International Energy Agency’s (IEA) Energy in Buildings and Communities Programme (EBC), a new paper presents unprecedented typical and extreme weather datasets for assessing the resilience of buildings to climate change and heatwaves. These datasets include essential climate elements such as ambient air temperature, relative humidity, atmospheric pressure, direct and diffuse solar irradiance, and wind speed at hourly resolution for 15 major cities across 10 climate zones worldwide. Covering historical (2001–2020), future mid-term (2041–2060), and future long-term (2081–2100) periods, the datasets are available in EnergyPlus weather file (EPW) and CSV formats. Generated from projections of one regional climate model and bias-corrected using multiyear observational data for each city, they incorporate complex future climate changes for the frequency, duration, and magnitude of extreme temperatures. The source codes to generate these datasets is accessible here.
