A. Definition of Words Beginning with the Letter "A."
Acoustical Separation. An area or component provided for the purpose of restricting sound transmission between abutting areas or building modules.
Arcades. Covered walkways attached to buildings and supported on one side by columns. Arcades provide pedestrians with shelter and can serve to provide large buildings with a more human scale.
Articulation. The visible expression of architectural or landscape elements through form, structure or materiality. Articulation provides a method for reducing the scale and breaking up the mass of buildings and plazas.
Awnings. Roof-like shelters, generally of canvas, that project from the wall of a building. Awnings serve to provide protection for buildings and pedestrians against the harsh elements of sunlight and weather.
B. Definition of Words Beginning with the Letter "B."

Bays. The term "bays" may be used when referring to the structural design of a building or when referring to parking lot design, as follows:
1) Bays of a Building. Structural modules occurring between the vertical means of support. Structural bays generally occur between columns or load-bearing walls.
2) Parking Bays. Bays in parking lots are a "complete" parking module consisting of a drive aisle with perpendicular or diagonal parking on one side (single-loaded parking bays) or both sides (double-loaded parking bays) (see figure, right).
