Includes what can be considered the public circulation space for a leased building; the entry, lobby, elevator lobbies, main corridors, and exits required for building codes.
Primary circulation space
How much space is needed for one student in a standard classroom, including space required for circulation, teachers desk and shelving?
15 - 20 square feet
The actual area required to accomodate specific functions. Does NOT include primary or secondary circulation space, closets, electrical and telephone equipment rooms, exterior walls or the building core. Does include interior walls and building columns.
Net area
One of the best sources of information for design professionals.
Trade associations. Example AWI (Architectural Woodwork Institute).
Includes the corridors in private leased areas used to connect the net assignable areas to the primary circulation areas.
Secondary circulation space
Ratio of the net area to the usable area. Takes into account the required circulation space. Most office and retail spaces the interior layout efficiency is about .70 to .80. This means that about 20% to 30& of the total useable space is devoted to circulation.
Interior layout efficiency
Total amount of usable space available. Also includes structural columns, thickness of some partitions, and typically a portion of the exterior wall of the building.
Rentable area
Measured from the inside glass surface of exterior walls (if the glass is more than 50% of the wall area) to the finished surface of the tenant side of the public corridor partition, AND from the centerlines of the partitions separating adjacent tenant spaces. Also includes a proportionate share of the elevator lobby, public corridor, rest rooms, and mechanical rooms.
Rentable area for an office lease that occupies only a part of a floor.
Includes all the area of the floors that are totally enclosed, measured from the outside faces of the exterior walls.
Gross area
No strict organization method of workflow.
Network workflow
Can provide the designer with the most current, authoritative data on a particular manufacturer’s products.
Product information. Many maufacturer’s publish a portion of their product literature in the Sweet’s Catalog.
Hierarchical, typically with one group controlling the other.
Departmental workflow
Rentable area divided by the usable area.
Rentable useable ratio
Includes all the spaces taken by the public corridors as well as the elevator lobby and the rest rooms on that floor. Partitions separating adjacent tenant spaces and separating a tenant space from public spaces are called demising walls.
Rentable area for an office when a tenant occupies the ENTIRE floor.
Area available for assignment to a tenant, including the actual net area (where activites take place), and the secondary circulation space.
Useable area
