AIR INDUSTRIAL BUILDING STANDARD

Building with no recessed and/or projections, and no rentable mezzanine. In the case of an industrial building whose Exterior Walls consist of a single vertical plane with openings for personnel doors, truck doors and windows, the Gross Building Area shall be determined by:

1. Measuring the distance from the Exterior Surface of one Exterior Wall to the Exterior Surface of the Exterior Wall directly opposite, and
2. Multiplying the building width X the building depth, and
3. Adding or subtracting the area(s) of non-rectilinear portions of the building (if any)

Building with no recesses and/or projections. plus rentable mezzanine. In the case of an industrial building whose Exterior Walls consist of a single vertical plane with openings for personnel doors, truck doors and windows, and the interior of the building includes Rentable Mezzanine, the Gross Building Area shall be determined by:

1. Following the same steps as above in AIR Building Standard #1 with respect to the Footprint, and 
2. Measuring the area within the Rentable Mezzanine and
3. Adding the area of the Footprint to the area of the Rentable Mezzanine.

Building with recesses such as an interior truck well recessed glass, and /or projections. with no rentable mezzanine. In the case of an industrial building one or more of whose Exterior Walls consist of two or more vertical planes as a result of the existence of :

• Recessed entry or window elements
• Projecting entry or window elements
• Interior recessed truck well or rail loading area
• Covered truck dock the Gross Building Area shall be determined by:

1. Determining the Dominant Portion of any Exterior Wall containing any of the projecting or recessed vertical planes referred to above, and
2. Determining the width and/or depth of the building based on the distance from the Exterior Surface of the Dominant Portion of any such Exterior Wall to the Exterior Wall directly opposite,
3. Multiplying the building width X the building depth using the Dominant Portion dimension(s), and
4. Adding or subtracting the area(s) of non-rectilinear portions of the building (if any).

Published in 1993 by the American Industrial Real Estate Association (AIR), it was the only measurement standard in the United States to address the measurement of lease space in industrial buildings until it was displaced by the publication of the BOMA Industrial Standard in 2004.

Building with recesses such as an interior truck well or recessed glass, and /or projections, plus rentable mezzanine. In the case of an industrial building one or more of whose Exterior Walls consist of two or more vertical planes as a result of the existence of:

• Recessed entry or window elements
• Projecting entry or window elements
• Recessed truck well or rail loading area
• Covered truck dock and the interior of the building includes a Rentable Mezzanine, the Gross Building Area shall be determined by:

1. Following the same steps as in Building Standard #3 with respect to the Footprint, and
2. Measuring the area within the Rentable Mezzanine in accordance with, and
3. Adding the area of the Footprint to the area of the Rentable Mezzanine.

In the case of a portion of a larger industrial building being leased separately, the gross dimension(s) of either the width the depth of such portion involving an interior Demising Wall shall be measured to the centerline of any such interior Demising Wall. In all other respects the Gross Building Area shall be determined in the same manner as in Building Standards #1 through 4.

A “Demising Wall” is any interior wall dividing one separately leased or occupied portion of a building from another.

The “Dominant Portion” shall mean that portion of the Exterior Surface within any one vertical plane which is both (i) structural in character and (ii) whose total surface area contains the highest percentage of the total Exterior Surface area of that one Exterior Wall. By way of illustration: (i) if 60% of the Exterior Surface of one Exterior Wall of a building consists of recessed glass storefront falling within a first vertical plane; and (ii) 10% of the same Exterior Surface is structural in character falling within a second vertical plane; and (iii) 30% of the same Exterior Surface is structural in character and falls within a third vertical plane, the 30% of the Exterior Surface which is structural would be the Dominant Portion for the purpose of determining the Exterior Dimensions.

The dimensions of a building determined by measuring the distances around the Exterior Surface of the Exterior Walls, based on the Dominant Portion of each Exterior Walls. OR, in the case of a buildings being connected by a common wall shall be measured to the center line of any connecting walls (Demising Wall) separating one Building from another.

The “Exterior Surface” refers to the outside surface of any structural or non-structural component of an Exterior Wall falling within a given vertical plane in any one Exterior Wall. Windows and doors mounted in an Exterior Wall shall be deemed to be in the same vertical plane as the Exterior Wall so long as their thickness lies within the thickness of the Exterior Wall, or so long as they are mounted directly to the interior surface or Exterior Surface of the Exterior Wall.

The “Exterior Wall” refers to the outermost structural wall, including its non-structural components, which forms the external perimeter of a building.

The “Footprint” of a building is the area of land occupied by a building, or portion of a larger building, calculated based on its Exterior Dimensions. For example, a building with Exterior Dimensions of 100 ft. X 200 ft. has a Footprint of 20,000 s.f. A Mezzanine (whether Finished or Storage Mezzanine) is never included in the building Footprint under any circumstances.

The “Gross Building Area” of a building is the total area comprised of the building’s Footprint plus Rentable Mezzanine, based on Exterior Dimensions. If the Rentable Mezzanine includes any Storage Mezzanine area: 1. The exact square footage of the Storage Mezzanine area to be included must be clearly identified; AND 2. It must be clearly stated that the Storage Mezzanine area so identified is included as Rentable Mezzanine in the Gross Building Area.

Is a floor structure within the Exterior Walls capable of supporting offices, warehousing or manufacturing activities, as a function of load-bearing capacity and compliance with applicable building codes governing the purpose for which the Mezzanine was constructed.

To qualify as finished “Office Area,” an area within the industrial building must be developed at least to the extent of the addition of ALL of the following improvements, whether constructed on the ground floor or the Mezzanine:

1. Frame and drywall partition fully separating the Office Area from adjacent areas of the industrial building, constructed at least to the height of an intersecting finished interior ceiling (not the underside of the exterior roof of the building).
2. T-bar suspended ceiling or joisted ceiling with a fully finished interior surface.
3. Ducted heating and refrigerated air conditioning.
4. Fully finished floor covering (carpet, tile or sheet goods).
5. Lighting at an intensity throughout of not less than 50 f.c. at desk height.
6. Minimum electrical required by code.

A building which is designated as a property’s “Principal Structure”, may be so designated by virtue of:

1. Its size, OR
2. Its location on the property, OR
3. Its architectural character and importance, OR
4. Its structural components, OR
5. Any combination of these.

Any mezzanine constructed in accordance with applicable building codes, other than a finished mezzanine.
