*Square Footage Standards Flashcards
Space requirements are determined by:
1.) Functional needs per square foot
2.) Size of an object
3.) Activity planned in the space
4.) Building code requirements
What is BOMA?
Building Owners and Managers Association
the most common measurement methods and is considered a standard
What is the gross area?
Floor area construction.
the floor area within the building’s exterior face or boundary, including the exterior wall’s thickness. It is the total constructed space. This measurement is used in evaluating building efficiency and comparing the construction costs of various projects.
What is a rentable area?
The revenue producing floor area
What is the usable area?
Those that are occupiable by tenants
net area plus the circulation area
What is Net area?
The space required for the function or the program area.
The net area includes individual workspaces, dedicated and shared support spaces, and special mission-critical spaces.
The net area does not include other areas like corridors, wall thicknesses, washrooms, and mechanical rooms.
What are the two types of circulation areas?
Primary and secondary
Primary = main route connecting building core and common spaces (public corridors, elevator lobbies, stairs)
Secondary = private circulation area that connects to the primary areas and public corridors. (aisles between support areas)
What is the circulation path multiplier?
determines the total usable area required
It is multiplied by the net area to estimate the amount of circulation area that should be included in the usable area (USF). It is NOT the same as the circulation factor.
Circulation Multiplier is the inverse of the efficiency factor
What is occupant area?
The occupant area of a space is the total portion of a building being “actively used by a tenant.”
This means that the occupant area is the NSF, as determined by the total of programmable spaces, PLUS (+) circulation, and any incidental spaces (such as columns and other items) within the tenant’s space.
But it’s always important to know that the occupant area is ALWAYS more than the net programmable area.
What is rentable area?
The floor area that the tenant pays rent on is the Rentable Area.
This is usually defined as the interior floor area excluding vertical penetrations through the floor (e.g., air shafts, elevators, and stairways). The rentable area includes structural elements such as columns and interior and exterior wall thicknesses. This calculation determines the income-producing capability of a building.
What is efficiency factor?
The efficiency factor is used to calculate the gross area to include circulation and non-usable areas.
What is incidental space?
Incidental space is the project area not occupied by the client, like closets, structural columns, and walls but is needed to create the client’s overall space plan.
What is the building service area?
The Building Service Area provides necessary services or circulation for normal operation. It includes the main and auxiliary lobbies, building access and egress, building mechanical rooms, building electrical rooms, security and fire control rooms, publicly accessible restrooms, and building operation offices.
What is the floor service area?
The Floor Service Area provides services or circulation required for the normal operation of the building. It includes restrooms, bathrooms, janitorial closets, floor electrical and phone rooms, and floor utility or mechanical closets.
What is the building amenity area?
The Building Amenity Area is shared among tenants and includes shared conference rooms, food service facilities, health or fitness centers, and daycare facilities. It represents the non-permanent portion of the building convertible to a tenant area.
