Welcome to the TRNSYS Users Forum.

The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.

Some tips for success on using the forum:

  • Follow the Forum Rules posted in Forum Administration.
  • There are categories for different types of topics and questions. Post your topic or question into the proper category.
  • Before posting a topic or question search the existing topics  (and the TRNSYS Users listserv archive or Post archive) to see if a similar topic or question has already been answered.
  • Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
  • State the version of TRNSYS and which add-ons your are using.
  • Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
  • Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
  • Moderators may edit your post for clarity or move your topic to a more appropriate category.

CFS and Daysim calculations

Dear Trnsys users

I'm confused about the exact role of the CFS model in the Type 56.

I understand that it was specifically dedicated to better calculate heat transfer from the air gap between the glazing and a shading device (ISO 15099).

But I can see in some papers that CFS also leads to daylighting calculation (using the BSDF files). Myself, I have the feeling that I need the CFS model to have better energy results with a shading device but I still need to perform daylighting calculation with the Daysim tool in the Type 56.

To complete on that, I don' see any output related to daylighting in the Type 56 with CFS.

 

What do you think about that ? Is it right to still perform thermal calculation with CFS and daylighting calculation with the Daysim tool ?

 

Best regards
