The current occupant load factor of 100ft2/person, as specified by NFPA 101, Life Safety Code, and NFPA 5000, Building Construction and Safety Code, for business uses has been in effect since the 1930’s. Business use areas, specifically office environments, have changed since that time, and questions have arisen regarding the appropriateness of the 100ft2/person factor for all types of business use areas. This study investigates the origins of the 100ft2/person factor, previous occupant load studies, changes in office space planning and use, availability of office furnishings, and current office occupant load preferences, then recommends alternate occupant load factors and business use categories.
