I want to model a building which has open spaces in some areas. i.e. in some areas in floor one, the ceiling height is different from others. is there a way to draw it inside of openstudio without using the sketchup ?

Yes, you can do this directly in the OpenStudio App:

1) Click on the >> button to allow space-specific properties.

2) Type in different values for e.g. Floor to Ceiling Height.

3) When you go to the 3D geometry rendering, it should reflect the height difference.

I'm assuming that "to draw it inside of OpenStudio" (not SketchUp) means the FloorspaceJS editor. I'm only somewhat familiar with the editor - hopefully experienced users will correct me with editor subtleties that may simplify the following steps.


This is how I would approach a 2-storey lobby using the editor. The editor-generated lobby below is made up of 2x superimposed spaces ("Space 1-2" & "Space 2-2"), each with their own unique thermal zone. The selected interzone Floor, "Face 18" (of "Space 2-2"), is matched with an interzone RoofCeiling, "Face 7" (in "Space 1-2" below).

Lobby intermediate Floor/RoofCeiling

Adding a new AirBoundary Construction.

Assigning the new AirBoundary Construction to "Face 18" and "Face 7".

Making sure "Space 2-2" is not part of the total floor area.

I'd then start going over inter alia:

  • the split in lobby lighting (between "Space 1-2" vs "Space 2-2")
  • the Air Boundary Construction air exchange (between "Space 1-2" & "Space 2-2")
  • whether the upper part of the lobby ("Space 2-2") is (directly) mechanically ventilated/exhausted
  • whether the upper part of the lobby ("Space 2-2") holds heating equipment
  • and so on ...

That's a simple case. Depending on the configuration and E+ version, you may trip over a few hurdles (e.g. this fix a year ago). I'd suggest incremental experimentation.
