[Bldg-sim] Modeling partly exposed roof in each floor with eQUEST

[Aulbach, John]

I BELIEVE, Sir, that eQuest will treat any exposed roof will be roof and
any adiabatic floor to floor will be floor.
 
Where you can get goofed up is a plenum that covers the entire floor.
Try to keep each space with its own plenum, or can the plenums all
together.

Subject: [Bldg-sim] Modeling partly exposed roof in each floor with
eQUEST


Hello, all,

I have a question regarding modeling roof in eQUEST. In the high-rise
building that I am going to model, each floor will have partly exposed
floor (the bottom floor has the largest footprint and gradually reduced
foot print in the upper floors) and shape is complicated. 

Does someone has some experience to model the roof? Since each floor has
partly exposed roof, when I model the roof as adiabatic, then the
exposed roof will be missing. If I model the whole floor with roof, then
lots of roof will be redundant. If I delete these redundant roof, then
some zones will be exposed to the exterior without roof while there
should be some roof area.

I found it is difficult to create roof shape with plolygon in eQUEST. Is
the separation of the parts with and without roof into different shells
the best way to model this condition or is there any better methods?

Thanks a lot for your help.

Regards,

David
