Revision history [back]

BEopt is supposed to create the weather cache file on the fly but there appear to be situations where it doesn't. If you are a reasonably savvy user, you can force BEopt to create the cache files like so:

1. Copy the EPW files into your BEopt weather dir: C:\Users\USERNAME\Documents\BEopt_3.0.1\Weather\
2. Open Windows Powershell
3. Navigate to the BEopt install dir: cd 'C:\Program Files (x86)\NREL\BEopt_3.0.1\'
4. Run this command to generate the cache files: .\Include\OpenStudio\bin\openstudio.exe .\Workflow\run_simulation.rb --cache-weather C:\Users\USERNAME\Documents\BEopt_3.0.1\Weather\

You may see some messages appear that are safe to ignore. But if it worked correctly, cache files will be generated in your weather dir for any EPW file that doesn't have a cache file already.

If that doesn't work or you can't figure it out, feel free to email me and I can send you the necessary cache files.

(FWIW we are removing the need for the cache files for the next version of BEopt, but I do not know when it will be released.)
