RE: [EnergyPlus_Support] Heat Transfer Surface geometry

RE 2)  you have to flip the order of the vertices between the "floor"
and "ceiling" versions of each surface.  Setting the surface type won't
do anything to the geometry.

Subject: [EnergyPlus_Support] Heat Transfer Surface geometry

 

1) All roofs/floors with more than 4 sides do not appear on the 
graphical representation of the building model. Is this due to loss of 
information when data is translated from EnergyPlus to CAD? Has anyone 
else experienced this situation?

2) I am modeling the floors of a "Plenum Zone" as the respective 
ceilings of the zones below. In other words, I am using the same 
vertice coordinates for both surfaces but I am designating their 
surface types as Ceiling and Floor. EnergyPlus calculates the Tilt 
angle of the floors as 0.0 instead of 180. On pg 129 of the I/O 
reference, it is stated that any vertex can be chosen as the starting 
position for horizontal surfaces, as long as the VertexEntry 
convention is followed. Are there other parameters beside "surface 
type" and "vertice coordinates" used in coming up with the tilt angle 
of a surface? Don't quite understand why the floors have tilt angles 
of 0.0.

Thank you for your support.
