Hello - I have a sketchbox question. If I build a sketchbox model that ends up with some kind of exposed floor because the 2fl is larger than the 1st floor, is the tool modeling that exposed floor as I would expect? Thanks!
Hi glinn07,
When you enter the total floor area and the number of floors for a shell in Sketchbox, it divides the total floor area by the number of floors to come up with each floor's area. All floors in a shell have rectangular floor plans with identical footprints and are stacked on top of each other. No parts of the lower surfaces of upper floors are exposed to the exterior of the building. Does that answer your question?
Thanks Drew, I mean the situation where you have two "shells" stacked on top of each other, see picture I added in the original post
Thanks for clarifying, glinn07. When a shell is on top of another shell and has a floor that's partially exposed to the outside, Sketchbox treats the floor area directly above the lower shell as adiabatic. The exposed floor area is still modeled as an underground surface. This engineering reference page has more information (it's for Energy Plus, but I believe the DOE-2 algorithm is similar). If you want to explicitly model above-grade floors, you can download the .inp files and continue in eQuest.
Thanks Drew! :)
