TMY3 files for Europe based on CERRA data from 1985-2005

This dataset includes TMY files for the 5000 largest cities and towns in the EU, based on CERRA data from 1985-2005, and using a TMY3 methodology. The files represents a statistically typical year meant for energy calculations of buildings, and are therefore not suited for evaluating extreme conditions.

The repository contains:

• EPW-files - zipped collection of .epw-files
  • The most common file format for climate data for energy simulations applicable to most programs
• Changelog - a txt file
  • a overview of changes in the dataset since 1.0
