The hourly weather data files provided on this page are .WEA files (139 Kb) and are Binary. They are intended as example data for use in building simulation and analysis -- if you require specific year data or data source information, it is recommended that you source your own (and use the Weather Tool to import the data) as we are unable to provide this information.

The majority of files listed below, contain most if not all of the following:

• Dry Bulb Temperature
• Relative Humidity
• Direct Solar Radiation
• Diffuse Horizontal Solar Radiation
• Wind speed (not essential but preferable)
• Wind direction (not essential but preferable)
• Cloudiness
• Rainfall (not essential but preferable)

These files are for use with ECOTECT and the Weather Tool. To view the .WEA files you will need to download a copy of the Weather Tool.

Other data Formats and sources

.EPW Energy Plus Weather Data

The most reliable and comprehensive source of international weather data at the moment would have to be the EnergyPlus Weather Data site. With v1.20+ of the Weather Tool you can simply drag and drop the .EPW files from this site in to the Weather Tool to load them. Data for over 900+ international locations are available...

Generic ASCII data

Any format of ASCII (text only, human readable) format can be imported into the Weather Tool. For more detailed information about this process please refer to the Import Data section of the Weather Tool help file, and specifically the included tutorials:

• Importing Fixed Format Data
• Importing CSV Data

'tas' Weather Data

Some users might have access to 'tas' weather data. If so then this Excel Macro for preparing your data should be useful. Read this tutorial from the Weather Tool help to view the code for the macro in full, as well as an explanation for its use.

Import Format Files

In addition to the already converted .WEA files provided below, the following Custom Column Format (.CCF) files may be useful to some users.

• EnergyPlus CCF
• HTB2_import CCF
• HTB2_export CCF
• Meteonorm CCF
• tasXLStoCSVtoWEA CCF

The EnergyPlus conversion format is particularly useful with the data available from the EnergyPlus Weather Data site (with v1.10 or earlier of the Weather Tool).
