Dunnage: Structural support for HVAC, generators and other mechanical equipment on a roof of a commercial building.
Eave: The sloping edge of a roof overhanging the exterior walls, sometimes showing exposed rafters.
Elevation: The exterior upright face of a building as well as an architectural scale drawing of a façade. The main elevation will usually encompass an entranceway.
Façade: The main face of a structure usually found at the front of a building and often with more decorative details than other elevations.
Fanlight: A decorative or plain glass panel placed above an entrance door to a retail outlet. Some have a hinge at the bottom and can be opened inwards for ventilation. These are known as ‘hopper’ fanlights.
