For application within a commercial site scorecard, which of the following defines regular occupants?

The correct choice identifies regular occupants as those individuals who are considered to be present within owner-controlled areas of a commercial site. This includes anyone who regularly utilizes these spaces, which encompass employees, visitors, and other individuals allowed access by the property's management.

Understanding the definition of regular occupants is critical for accurately assessing and promoting well-being through design and operational practices within commercial buildings. By focusing on all occupants of owner-controlled areas, the scorecard can address the needs of a broad swath of individuals who may be impacted by the building's features and policies.

The other options do not capture the full scope of what defines regular occupants. Including only certain groups—like those using public transport or staff working in tenant spaces—would omit significant populations that contribute to the daily life and health of the commercial environment. Thus, they do not provide a comprehensive understanding applicable to the commercial site scorecard.
