Hey all! I came across an issue that I’m not sure if it might be a mistake on my end or a possible bug on the Create EpPlenum component.
I have two zones created with Zones2Masses and the top one is a plenum, which was created with Create EpPlenum. The issue is the following: the default construction assigned for both the bottom zone floor and the plenum floor is Interior Floor. But, at the same time, the top of surface of the bottom zone was assigned as Interior Ceiling, which causes an EnergyPlus Error since the constructions are not the same (at least in this case, where in my project they differ, being that the interior floor is concrete but the interior ceiling is a different material). The bottom surface of the plenum should be an Interior Ceiling as well.
I’ve attached an image to clarify.
