Re: [EnergyPlus_Support] Ceiling height warning

[Josh K <jeemang@xxxxxxxxx>]

Hi Eleni;

I often get this warning when I have a zone that has a tilted ceiling, or several different ceiling heights. I've modified the ceiling height value in the EnergyPlus simulations to test the resultant sensitivity, and in my experience it doesn't have a very large effect on the simulation results. That said, I recommend trying it yourself to be sure.

Dear All,

Has anyone come across similar warnings about ceiling heights?

** Warning ** Entered Ceiling Height for Zone="ATRIUM_1_" significantly different from calculated Ceiling Height
** ~~~ ** Entered Ceiling Height=12.36, Calculated Ceiling Height=7.07, entered height will be used in calculations.

My model is built in Ecotect and is then exported to Energy+. The geometry looks fine in Ecotect (including surface normals and vertices order).Thank you in advance for any help,

Best Regards

Eleni
