NCIDQ Interior Design Professional Exam (IDPX) Practice Exam

Primary circulation space refers to areas that facilitate the movement of people within a building or between different areas of a leased space, including pathways that guide occupants from one location to another, such as main corridors, lobbies, and exits. When examining the spaces listed, entry lobbies, exits required for building code egress, and elevator lobbies all fall under the category of primary circulation as they are essential for accessing different areas and ensuring safety and compliance with building regulations.

Main corridors in each private leased area, however, serve a more specific function. They provide access to individual leased spaces rather than facilitating movement through common areas shared among tenants or the public. This distinction is important because while main corridors are crucial for navigating a particular tenant's space, they are not primary circulation areas in the broader sense of the building's design and flow. Instead, they are secondary circulation spaces that serve the internal layout of individual lease areas rather than the overall building circulation. This understanding highlights why main corridors could be seen as less central to the primary circulation flow than the other options presented.
