Welcome to the IDA climate data download center

There are many weather data formats available. We have presently a selection of climate files available using the formats described below. It is also possible to download climate files directly from the Energy Plus database, see below after our climate data table for instructions, or click the link below to go directly to the Energy Plus homepage.

Weather files generated from Test Reference Year (TRY) files and ASHRAE IWEC files

The TRY weather files are the files with a (TRY) in their names in the table below and are composed from measured data of representative months to form a whole representative year. NB! These files do not contain information about wind direction.
