     This concept is used to a limited extent. It's used mostly in cases
     where there is a small area of a large building that is occupied
     consistently, such as a clerk counter in a warehouse, or where air
     exchange makes hot air heating unfeasible, such as an entrance foyer.
     They are also ceiling mounted units, rather than wall panels.
