Dimensions

Dimensional data can be entered in CoolCalc Manual J using "Map trace" or "Text" data source. Map trace is recommended for all projects except room-by-room load calculations or when the home is not visible on the map trace widget. Text data source is recommended for doing room-by-room load calculations or when the home is not visible on the map trace widget due to obstruction by trees, outdated satellite imagery or because the home is not yet built.

Note that in CoolCalc Manual J "room" is a rather flexible term, it can refer to one or more actual rooms in the home, an entire floor level or the entire conditioned space in the home. When doing a block load calculation we recommend that each floor level is treated as a separate "room" for best accuracy.
