TRNSYS Email List (

The Solar Energy Lab has set up an email list to help TRNSYS users communicate with each other.  Anyone in the group can submit a message, question, etc. to the list and the message will be automatically forwarded to everyone on the list. We hope this will provide a forum for additional technical support from other users, a chance to share user-written components, and express special needs for simulation programs. 

Two archives of the mailing list are now available:

  • The first one is an instantaneous archive in text-mode only (attachments are not saved and HTML- or Rich-text formatting is lost). You can find the archive at:
  • The second archive can be accessed here below. It is usually updated every few months. All messages are available with their original formatting and attachments.
