[Equest-users] LEED Compliance and Ceiling Plenums

Hi everyone,

I am trying the LEED compliance feature of eQuest 3.64 and it does not seem to like my ceiling plenums.

Whether I set TYPE-ZONE as "plenum" or "unconditioned"; and whether I set ASHRAE 90.1 conditioning classification (reference) to "Not Included", "Unconditioned, Enclosed" or "Semiheated, RA Plenum" I always get the same error message:

"Assign zone to baseline floor system: CRule: Eval() error posting symbolic (value 5.18473e-296) result to BDL"

I found a discussion in the archives about this, but there was no solution other than removing the ceiling plenums. Is this really the only solution? Or is there a way to get it to work with ceiling plenums?
