[TRNSYS-users] Modifying TRN3D IDF File (Window Sizes), Applying Types to All or Selected Zones, and Schedules

[David BRADLEY]

Aaron,
   You would have to redraw the windows on the exterior walls but you 
would not have to recreate the entire model. I would start with your 
current model, save a copy, delete the windows, save that version, then 
redraw the windows that you want to resize.

   For adding a type to a lot of zones in the *.bui file, I think you 
have found the trick that I use. I typically add the type to the first 
zone, then I edit the *.bui file with a text editor to add it to all the 
other zones. Its much faster than adding the type in TRNBuild.

   For the schedules, I rarely use the schedules that are built in to 
TRNBuild. I almost always create INPUTS instead of SCHEDULES. Then I use 
external Types in order to define whatever value I need. In the case of 
the kinds of schedules that you speak of, look at the TESS Applications 
library; there is a holiday scheduler that will allow you to define the 
schedules that you want using a graphical plugin. If you do not have the 
TESS Applications library, you can define schedules using Type14 and 
then sequence them using Type41.
Kind regards,
  David
