Best way to model 1 floor only for loads

[bootsam]

If i have a multi story building and i only need the loads for one intermediate floor. How is it best to model the ceiling and floor? Should i create a dummy space above and below, ie another floor. Or is there an easy way to set temps across the floors and ceilings.

Draw a dummy floor above and below and then set them to be of type 'Adjacent Building'. The intermediate floor and ceiling will then be treated as adiabatic (i.e. no heat transfer).

Cant I just use the 'edit multiple adjacancies' to put a temp on the ceilings and floors? Gotta be easier or is there something wrong with this way.

[JohnLloyd]

You can, and it will probably give you similar answers, but that method will result in both the floor and ceiling of your single floor being unshaded.

This is probably not a huge issue but I think it will make the thermal mass within those constructions act differently due to the additional flux hitting their outside surfaces.

That would only be an issue in a dynamic simulation and shouldn't impact any steady state calcs.

Thanks John. Its only a steady state calc i am after. But I just needed confirmation that i can use both methods. Generally i dummy a floor but wondered whether i could use the adjancies instead.
