Building energy simulations require weather data as an essential input, and modelers have been searching for weather data for as long as building simulations have been done. ASHRAE, in collaboration with White Box Technologies (WBT), now provides instant access via the Web to ASHRAE's IWEC2 "typical year" weather files for 3,012 international locations outside of the US and Canada. IWEC2 weather files can be purchased either individually, or as sets by country or region.
For more information about the IWEC2 weather files, see About IWEC2 Data.
Searching for a weather station can be done either by filtered lists or by using Google Earth©. Click on Search by List to find IWEC2 weather files for individual stations grouped by country or political unit, or complete sets for 80+ countries and regions. Click on the Search by Google Earth© to see the IWEC2 stations shown as colored dots superimposed on the Google Earth© map of the world. For more information on selecting with Google Earth©, click on Select By GE.
