When evaluating space requirements, how should circulation space be treated?

When evaluating space requirements, circulation space is typically excluded from the net area calculations. The net area encompasses only the functional space utilized for specific purposes, such as the actual area needed for furniture, fixtures, and activities. Circulation space, which includes hallways, corridors, and other areas needed for movement through the space, is considered necessary for the overall usability of the design but is not included in the net area because it does not fulfill the primary functions required of the space.

By excluding circulation space from the net area, designers and planners can provide a clearer understanding of how much area is actually devoted to the intended activities and functions of the space, which is critical for effective planning and utilization of resources.
