vertical shadow angle


NOTE: This term was added in RP-16-17 Addendum 2.

The solar altitude angle projected onto a vertical plane perpendicular to a building facade or shading element edge. Alternatively, the vertical angle from a point to the linear edge of a shading element (e.g., overhang, light shelf, blind edge or adjacent building, rooftop) measured from the horizon in a plane perpendicular to that edge. Also called profile angle.
