The Room tree object occupies the next highest position in the hierarchy below that of the Floor tree object. A room can contain multiple surfaces such as walls, ceilings, partitions, and all associated sub-objects.

The Room object, when selected, provides an entry point to the room data on the Properties For: Room dialog. Here, you can modify room data on several properties panels under the general heading of Design Data (Steady-State Calculations) . These settings, when manipulated, define specific assumptions that affect steady state thermal calculations for room gains and losses.
