Air Walls divide rooms without a physical barrier. Sometimes referred to as Room Separation Lines or Holes, Air Walls provide flexibility to define rooms without walls. Typical use cases include:

  • Separating circulation from open office desk area

  • Separating informal seating areas from circulation

  • Dividing a reception desk from an open lobby

How to draw Air Walls?

Air Walls can be selected from the Building Elements. Simply pick from the drop down next to Walls. Once active you can draw Air Walls in the same as Walls. Be sure to utilize snaps to help keep everything square. Walls (Interior or Exterior) can be changed into Air Walls by selecting from wall type drop down in the properties panel.

Note: Air Walls cannot host Windows, Doors, or Openings. When an Exterior or Interior Wall is changed to an Air Wall, any existing doors, windows, etc. will be removed.

How does an Air Wall impact analysis?

Air Walls are not considered in the 3D Analysis (they're not really there after all). This means that daylight and views will pass through them. Air Walls do denote rooms, which can help when creating the Occupied vs Unoccupied LEED Report.

Air Walls also will not impact the Baseline Energy model. Again, they can be used to define detail rooms which can feed into the area-weight average definitions used for lighting, appliance, and occupants

For load calculations the Air Walls are considered Adiabatic (no heat transfer) and do not block solar gain. Again the primary use of an Air Wall is to separate between rooms that require a different template.
