. Average number of occupants standing or seated

To identify the regularly occupied spaces on a project, the LEED consultant should consider the

average number of occupants standing or seated in each space, as this is the criterion used by the

LEED Reference Guide for Green Building Design and Construction, 20091. Regularly occupied spaces

are defined as areas where workers are seated or standing as they work (or perform regular tasks)

inside a building2. The typical duration of occupancy in each space per day is not necessarily

relevant, as some spaces may be used intermittently but still qualify as regularly occupied2. The rate

of outdoor air provided per person and the fire ratings of installed wall and ceiling assemblies are not

related to the definition of regularly occupied spaces, but rather to other credits such as Indoor

Environmental Quality or Fire and Life Safety.
