module 02 | project assessment + codes Flashcards
what is the order of hierarchy for building square footage designations?
- gross area (gsf)
- rentable area (rsf)
- net area (nsf)
- usable area (usf)
what is usable area?
the space occupied by tenants, including net area and circulation
excludes building core + common spaces
what spaces does the usable area exclude?
building core + common spaces
ex: elevators, exit stairs, mechanical / electrical rooms, core restrooms
what is the calculation for usable area?
usable area = net area + circulation area
what is net area?
the space required for the function of the space
what spaces does net area include?
workspaces + dedicated support spaces
ex: workstations, offices, conference rooms, break rooms, copy rooms, etc
what is an example of net area?
an 8’ x 8’ workstation is 64 nsf. 10 workstations would be 640 nsf + circulation space
how is net area calculated?
net area is found by adding together all programmed areas
what is rentable area?
the floor area that the tenant pays rent on
ex: everything inside the building, including wall thickness and structural elements
what spaces are excluded in the rentable area?
major vertical penetrations
ex: stairs, elevators, shafts
how is circulation area calculated?
circulation area = nsf x (circulation multiplier - 1)
what is the calculation for rentable area?
rentable area = usable area + prorated share of building common area
what does the circulation multiplier allow one to calculate?
the circulation multiplier allows one to calculate how much additional space is needed outside of the programmed total
what is gross area?
the floor area within the building’s skin
ex: everything including exterior wall thickness
what is the calculation for efficiency factor?
efficiency factor = nsf / total occupant area
what is the occupant area?
the amount of space being actively used by the tenant
if glass is more than 50% of the wall area, how is the occupant area measured?
occupant area is measured from the interior face of the glass to the centerline of demising partitions
if glass is less than 50% of the wall area, how is the occupant area measured?
occupant area is measured from the exterior wall’s interior finish face to the centerline of adjacent demising partitions
how are net/gross ratios determined?
net/gross ratios are determined by dividing the nsf program total by the efficiency factor
ex: net/gross = nsf / efficiency factor
what is the term for the formal designation for the primary use of a building?
the occupancy classification
what is a group e occupancy?
educational - for grades 12 and below
what is group b occupancy?
business - any space used for offices, professional, or service transactions
when does an assembly occupancy become a business occupancy?
- if the space has an occupancy load of fewer than 50 and is accessory to another occupancy
- if the space is less than 750 sf and an accessory to another occupancy
what is a group i occupancy?
institutional - spaces / buildings for people under care or supervision incapable of exiting the building unassisted
what types of spaces fall under i occupancy?
- hospitals / surgery centers
- correctional facilities
what is a group m occupancy?
mercantile - any retail or wholesale store and showroom
what is a group r-1 occupancy?
sleeping units with transient occupants
ex: hotels + motels
what is a group r-2 occupancy?
sleeping units in more than two dwelling units with primarily permanent occupants
ex: apartments + condos
what happens to the occupancy classification of an educational assembly space with an occupant load of 35 in a university setting?
because of the occupant load, the group a designation becomes a group b
zoning sets limits on what four building-related items?
- use
- size
- height
- position on the land
what is the difference between an institutional and business occupancy classification in a hospital setting?
the main difference is the occupant’s ability to exit the building on their own.
- business | the occupant can exit independently
- institutional | the occupant cannot exit unassisted
how do occupancy classifications differ from occupancy groups?
occupancy groups live under occupancy classifications and provide more detail about the intended function / use
what is ansi / bifma x5.1? and what pieces or furniture does it focus on?
the american national standard for office furnishings - general purpose office chairs
what is ansi / bifma e3?
the furniture sustainability standard
what is ansi / bifma m7.1?
standard test method for determining voc emissions from office furniture systems, components, and seating
what is ansi / bifma x7.1?
standard for formaldehyde and tvoc emissions of low-emitting office furniture systems + seating
what does tvoc stand for?
toxic volatile organic compounds
what does ansi / ashrae 62.1 measure?
the ventilation for acceptable indoor air quality
what does ansi / ashrae 62.2 measure?
the ventilation and acceptable indoor air quality in low-rise residential buildings
what is ansi / ashrae / ies 90.1?
the energy standard for buildings except low-rise residential buildings
what is nfpa 252?
the standard methods of fire tests of door assemblies
what is nfpa 253?
the standard methods of testing for critical radiant flux of floor covering systems using a radiant heat source
what is nfpa 265?
standard methods of fire tests for evaluating room fire growth contribution of textile or vinyl wall coverings on full-height panels + walls
what is nfpa 286?
standard methods of fire tests for evaluating the contribution of wall and ceiling interior finishes to room fire growth
what is nfpa 701?
standard methods of fire tests for flame propagation of textiles and films (vertical ignition test)
who is responsible for making sure the design complies with code?
the interior designer
what method does ibc use to establish a permit fee?
valuation
what is valuation?
the concept of valuation is based on the idea that the value of a project is related to the amount of work expended during the administration of the permit
essentially the complexity of the project directly affects the fee
typically a building permit costs what percent of the project’s overall value?
1% - 5%
