Global Climate Data Updates for Building Simulations Released
Global Climate Data Updates for Building Simulations Released
US · Published Jun 8, 2026
The website Climate.OneBuilding.Org has released significant updates to its climate data resources, aimed at supporting 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 files for Norway, Australia, and New Zealand. The site now hosts over 16,100 locations worldwide, with data spanning from 2004 to
The updates also incorporate solar radiation data from the ERA5 reanalysis dataset, providing comprehensive meteorological and climatological information. Additionally, the site has introduced hourly climate normals for thousands of U.S. locations, calculated over uniform 30-year periods. These datasets are designed to assist architects, engineers, and researchers in creating energy-efficient and climate-resilient buildings.

Why It's Important?

The updated datasets are expected to benefit professionals in the building and construction industry by providing accurate and localized climate data. This can enhance the design of energy-efficient buildings and improve climate adaptation strategies. However, users must ensure they are using the latest files, as older datasets may not reflect current climate trends or design conditions. The inclusion of solar radiation data and hourly climate normals also supports more precise energy modeling and sustainability planning.
