Weather Data Availability[LINK]

Typically, acquisition of weather data has been a user’s burden. Though this will remain the case in many instances for EnergyPlus users, the EnergyPlus team has been successful in making a wealth of US, Canadian and International data available to our users. To summarize, the weather data for 2092 locations is available at the EnergyPlus web site:

The details are shown in Table [table:summary-of-downloadable-weather-data-by-type]. Summary of Downloadable Weather Data by Type. This data has been selected with the energy simulation user in mind. All the data (as well as the statistical reports - described later in this document) are downloadable for individual locations.
