I've read about several people having the "Assign Zone to baseline floor system" when trying to run the LEED compliance Analysis. This error is mostly attributed to ceilings and plenums, which I have already corrected. Flr to flr height is equal to flr to ceiling, and return path of HVAC systems is ducted, but I'm still getting the error notice. Where else can I try to fix this error? The error notice doesn't guide me much on where to find the "mistake". Any suggestions?
the reason that error is usually attributed to plenums is because they are unconditioned spaces, which is the root of that error. So, check for any unconditioned spaces, switch them to conditioned and retry. (if it works, you can switch them back afterwards).
Thanks Joe! I had flr to flr height equal to flr to ceiling, so I had no plenums. I found the mistake and apparently, if you go to the Spaces Spreadsheet in the detailed mode, and go to Compliance - Occupancy (in the display mode) I had an undefined occupancy type for one of the spaces, and that was creating the error. So lesson learned, check that every space has it's occupancy defined. Hope this is useful.
