Special Note
This American National Standard is a national consensus standard developed under the auspices of the Building Owners and Managers Association (BOMA) International and certified by the American National Standards Institute (ANSI), of which BOMA International is a member and ANSI Certified Standards Developer. Consensus is defined by ANSI as “substantial agreement reached by directly and materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.” BOMA International obtains consensus through participation of its members, associated groups, and public review. Contact the Director of Codes and Standards at BOMA International to: a. Participate in the next review of this or any other BOMA International standard, b. Offer constructive criticism for improving the Standard, c. Permission to reprint portions of the Standard, or d. Register any inquiry concerning this Standard or any other BOMA International standard. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Interpretations of Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1-2010) may be obtained through the “Floor Measurement Standards Interpretations” in the QuickLink section on the BOMA International website home page at www.boma. org. Interpretations are provided by BOMA Recognized Floor Measurement Standards Interpreters. No person shall have the right or authority to issue an interpretation of this American National Standard in the name of the American National Standards Institute nor in the name of BOMA International except by BOMA Recognized Floor Measurement Standards Interpreters.

NOTE: This is a summary only. Refer to detailed descriptions below.
Step I: Determine the interior gross area (IGA) of the building and each of its floors by establishing the IGA boundary.
Interior gross area (IGA) is not used for leasing purposes, but it is the foundation of all further calculations in this standard. It is measured identically under Methods A and B. IGA excludes voids, interstitial space, and makes no deductions for columns and other projections necessary for the building. An IGA boundary should be determined for each floor of the building. The space inside the IGA boundary is the interior gross area for the floor. The combination of each floor’s interior gross area establishes the interior gross area for the building. The IGA boundary for each floor is established by applying the rules for the relevant conditions shown in Chart 1 and forms a perimeter around the interior gross area on the floor. For example, the most typical condition is vertical exterior enclosure. When you look up exterior enclosure on Chart 1, you can see that dominant portion determines IGA boundary placement for this condition. Once the IGA boundary is established for the floor the interior gross area can be calculated.
[ 6 ]
IGA boundary conditions are as follows: 1. Vertical exterior enclosure utilizes the concept of dominant portion to establish the IGA boundary for this condition. For an in-depth discussion on dominant portion, refer to Related Concepts below. 2. Public pedestrian thoroughfare replaces the concept of ground level street frontage in the previous standard. The IGA boundary is determined by applying the concepts of exterior enclosure and enclosure limit. For an in-depth discussion on public pedestrian thoroughfare, refer to Related Concepts below. 3. External circulation is a common condition in temperate climates where the primary circulation for the building occurs outside the exterior enclosure. When this condition exists the IGA boundary is determined as follows: • At above-grade level, the edge of the walking surface, limited to the width required for access to and egress from occupant suites, typically five to six feet. • At grade level, a vertical projection of the edge floor level or roof above, and/or limited to the width required for access to and egress from occupant suites, typically five to six feet.

New Terminology
To aid those who are familiar with the predecessor standard, ANSI/BOMA Z65.1-1996, the following list shows new terms from this standard that have general equivalents to those used in the predecessor standard. Note that this standard may not measure the area defined by the new terms in exactly the same way nor use them in the same manner. For instance, voids were previously measured as major vertical penetrations that were included in gross measured area, but voids are now excluded from interior gross area and have different rules for locating their measurement boundaries. The term usable area has been redefined. In the previous standard it included office area, store area and building common areas. In this standard, building common areas have been split into two classes of space, building service area and building amenity area, and usable area now excludes building service area. Terms whose meaning is generally unchanged from the predecessor standard (such as rentable area, dominant portion, etc.) as well as new terms that have no direct equivalent to a term in the previous standard (such as restricted headroom) are not included in this list. new term in this standard
