Office Buildings: Standard Methods of Measurement - English Version (ANSI/BOMA Z65.1—2010)
BOMA has been the leader in floor measurement standards for nearly 100 years, and the Office Measurement Standard is the one that kicked the whole thing off. Coined the "BOMA Standard" by practitioners for its widespread use, it has been revised periodically to reflect the changing needs of the real estate market and the evolution of office building design.
This latest version, Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1—2010), provides a uniform basis for measuring rentable area in both existing and new office buildings by taking a building-wide approach to floor area measurement. It provides a methodology for measuring both occupant space as well as the space that benefits all occupants.
Features of the 2010 Office Standard include:
- Single Load Factor Method calculation that can be applied to the occupant area of each floor to determine the rentable area and is the same for all floor levels of a building. This new “Method B” has been added as an option. The general methodology of the 1996 Standard has been continued to Legacy Method A.
- A new class of space, “Occupant Storage,” for measuring certain occupant areas in a building, such as basement occupant storage, that is not calculated in the Single Load Factor.
- Regional leasing practices, particularly for tropical climates, allow for enclosure requirements and limited (unenclosed) circulation.
Who benefits from BOMA Standards? A cross section of real estate professionals: building owners, property managers, facility managers, architects, space planners, interior designers, engineers, leasing professionals, asset managers, appraisers, brokers, general contractors and many others.
