USF - ✔✔Usable area (usable square footage): a measure of building area that subtracts space which is
not considered "occupied," such as lobbies, corridors, building core.
USF: NSF + Circulation Area
RSQ - ✔✔Rentable Area (rentable square footage: 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.
It also includes a portion of shared spaces (food service, lobbies, restrooms, etc.)
RSF = USF + prorated share of Building Common Area
GSF - ✔✔Gross square footage: total constructed area of the building, including things like lobbies and
hallways, and exterior wall thicknesses.
efficiency factor - ✔✔The efficiency factor for leased space is the ratio of the net area to the total
occupant area. The occupant area is the entire portion of a building being actively used by a tenant.
NSF - ✔✔Net Area (net square footage) Net Area is the space required for the function in the space or
the program area. For example, the net area of an 8' x 8' workstation is 64 NSF. So, ten (10) workstations
would require 640 NSF, plus circulation.
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.
In the hallway of a commercial space, the bottom edge of a pendant light must be at least how high
above the finished floor? - ✔✔80" (2032 mm) AFF
1003.3.1 Headroom.Protruding objects are permitted to extend below the minimum ceiling height
required by Section 1003.2 where a minimum headroom of 80 inches (2032 mm) is provided over any
circulation paths, including walks, corridors, aisles, and passageways. Not more than 50 percent of the
ceiling area of a means of egress shall be reduced in height by protruding objects.
, The performance level standards that mechanical engineers and refrigeration specialists use are
developed by: - ✔✔ASHRAE
ASHRAE®, formerly known as the American Society of Heating, Refrigeration, and Air‐Conditioning
Engineers (ASHRAE), was formed in 1959 to sponsor research projects and to develop performance level
standards for HVAC and refrigeration systems. Mechanical engineers and refrigeration specialists and
installers use ASHRAE standards.
During space planning, the designer must locate a 36-inch (915 mm) door along the main parallel
corridor that leads into another room.
Limited space is available, and the door will have a latch only, with no closer.
To provide for accessibility and minimize the width of the corridor, which of the following door
orientations and approach directions would best meet the criteria? - ✔✔
What is (OSHA)? - ✔✔Occupational Safety and Health Act of 1970 - was established by the US Congress
to assure safe and healthful working conditions for working people.
What is ASTM E-84 - ✔✔Standard Test Method for Surface Burning Characteristics of Building Materials
What percentage of the population exhibits a form of neurodivergence? - ✔✔15 - 20 %
What is the Clear door width required for a barrier free doorway? (According to 2009 ICC A117.1
Accessible and Usable Buildings and Facilities) - ✔✔Door openings shall have a clear opening width of 32
inches (815 mm) minimum. Clear opening width of doorways with swinging doors shall be measured
between the face of the door and the stop, with the door open 90 degrees.
What is the clear door / doorway width required for openings more than 24" in depth? - ✔✔Openings
more than 24 inches (610 mm) in depth at doors and doorways without doors shall provide a clear
opening of 36 inches (915 mm) minimum. There shall be no projections into the required clear opening
width lower than 34 inches (865 mm) above the finish floor or ground.
