Global Climate Data Updates for Building Simulations Released
The website Climate.OneBuilding.Org has released updated climate data files tailored for building simulations. These updates include refreshed Typical Meteorological Year (TMY) files and new datasets for various regions. Notable additions include the 2025 ASHRAE Design Conditions, updated California Climate Zones, and new datasets for Norway, Australia, and New Zealand. The site now hosts over 16,100 locations worldwide, with data spanning from 2004 to 2023. The updates also incorporate solar radiation data from the ERA5 reanalysis dataset, enhancing the accuracy of climate modeling for building design. Additionally, the site has introduced hourly climate normals for the U.S., covering a 30-year period and including temperature, precipitation, and other climatological variables.
