To make area calculation consistent and fair, standards need to be used. We need agreed-upon definitions of where measurements should be taken to and how common or shared space should be allocated. Although it is not the only one, the dominant standard that defines how to measure and calculate area in commercial buildings is published by BOMA Building Owners and Managers Association.

Other standards are occasionally used.

There is a standard, a standard and there are different methods for calculating office, store and industrial areas. Learn more about each standard. It is still important because area numbers based on this standard are in use on leases today. Common areas are allocated on a floor by floor basis. The main difference between the and standards is that the version includes a method to proportionally allocate building common areas as well as floor common areas to suite rentable areas.

There are also so minor differences in how area lines are to be determined. This is the successor to BOMA There are two options available, Method A and Method B.

Method B allocates the common areas in the building is a way that results in all the floors having the same gross-up factor.

In both cases, total building rentable area remains the same as BOMA For more details, see below. This is the latest version of the Office measurement standard.

There are some significant changes which in most cases cause the building rentable areas to increase. These included i Option to include balconies and finished rooftop terraces in rentable area ii Major Vertical Penetrations at lowest level are included in rentable area. Users can choose one of the two dominant market practices observed in North America – the Exterior Wall Methodology or the Drip Line Methodology – depending on their specific building configuration.

This is a standard used for facility management and should not be used for lease negotiations. It provides a definitive procedure for measuring and classifying floor area in buildings for use in facility management, specifying occupant requirements, space planning, and for strategic facility planning.

They have their own definitions for area that are published online here. It is not available online, but can be ordered by phone: Greater Washington Commercial Association of Realtors. The BOMA standard is designed so that a landlord is able to charge rent for all the area in a building.

BOMA Standards

This is done by grossing up the usable area that a tenant has inside their suite by a factor that accounts for a proportionate share of the spaces that the tenant shares with other tenants: Area is calculated in several steps: First the building is surveyed and drawn up on CAD.

Usable space, common areas and vertical penetrations are delineated according to specific rules. Vertical penetrations such as elevator shafts and stairwells znsi subtracted from the area of each floor. The usable area of each suite is calculated. A ratio between the total area of the floor and the total usable area within suites on the floor is calculated. The usable area in each suite is grossed up to arrive at the floor rentable area. A ratio between the total of all the floor rentable areas and the total area of the building including building common areas such as the lobby and mechanical spaces is calculated.

It sounds complicated, but it is quite rational and logical. The standard uses a spreadsheet that performs these calculations from left to right so that it is easy to follow.

We use a colour coding system that helps you relate the areas on the drawings to the cells in the spreadsheet. We colour-code and label the areas on the drawing: It is clearly written and has several good illustrations. The BOMA standard for measuring office amsi can be bomma bit confusing. What makes it a bit odd as a standard is that it includes two completely different ways to allocate common areas in the building.

There is a Method A and a Method B. Landlords can choose to use one method or the other. What follows here is a very brief editorial overview:.

BOMA Floor Measurement Standards-Overview

Method A is know as the “legacy” method. Also, if a floor anis configuration was changed, then the gross-up on that floor would change. Method B creates a single load factor or gross up for the entire building by means of two innovations.

First, it uses the concept of “base building circulation”. This is the circulation or corridor configuration that would be required in a typical multi-tenanted floor layout.

Ansii may not correspond to the actual circulation on any particular floor. The next innovation is to then gross up all the useable space in the building equally. You can think of this as treating all the suites as though they were all on a single floor.

The benefit of Method B is that it allows landlords to apply a single load factor ratio to all of the space in the building. The drawback is that this method relies on a concept of “imaginary circulation” that can be confusing. The new concept of Inter-Building Area allows service and amenity areas to be allocated specifically to the occupants that derive a benefit from the areas. An example would be a mechanical room that services a specific group of occupants, or to allocate common areas in a more targeted way for floors with multiple cores.

This concept can also be used to allocate areas shared by multiple buildings previously known as Campus Area or Complex Common Area.

The concept of dominant portion determines whether the area is measured to the glass line or inside wall face at windows along the exterior enclosure. In the standard, only the first 8 feet up from the finished floor is taken into consideration when determining the dominant portion.

For some buildings, this will mean a decrease in the rentable area. The following is a presentation that we use to give an overview of BOMA standards for measuring office buildings:.
