For more than a century, BOMA International has set the standard for measuring buildings.  In 1915, BOMA published its first Standard Method of Floor Measurement for Office Buildings, an accepted and approved methodology by the American National Standards Institute (ANSI).  Throughout the years the standard has been revised to reflect the changing needs of the real estate market and the evolution of office building design.  Today, BOMA is the secretariat for a suite of measurement standards.
