Search for EPW weather files to use in EnergyPlus building energy simulation from White Box Technologies. Use the interactive map to search for your required location and download a weather file from one of the nearest three IWEC2 locations.

We also have some other weather-related resources:

  • Wunderground weather station data – download historic weather data from weather stations around the world
  • Weather file finder – an Excel tool to find EPW files from sources other than IWEC2
  • Visualising the wind – an Excel tool for creating wind-roses

    This tool was developed in collaboration with White Box Technologies, experts on weather files for building performance simulation. It’s new, so your feedback is always welcome.
