The total portion of the building being actively used by a tenant.
16
Q
Efficiency factors generally range from?
A
.60 to .80 with most offices and retail spaces having an efficiency factor of .70-.80.
This means that approximately 20-30% of the net area (estimated required occupant area) is devoted to non-useable areas.
17
Q
The actual area each tenant uses is?
A
Occupant area.
In addition to a prorated share of portions of the building used by all tenants.
This and the load factor account for the rentable area.
18

Sets the tone for all of the egress.
20
Q
When getting the total occupant loads, what is the proper way to calculate this?
A
By calculating each individual space and then adding the totals.
Ie. sqft / by occupant load factor (table 1004.5) for ALL spaces, then add.
21

For electrical, in a complex plan of decent size and scale or for larger plans such as for complex commercial projects, the interior designer often draws a separate _______.
Power/communications plan.
This is different from the electrical engineer's power plan.
For a smaller scale project, the outlets are often shown on the furniture plan. The location of outlets would not be shown on the RCP, and the construction plan would become too cluttered with the required information.
28
On which drawings would you find the abbreviations NIC, BRK, FPL?
On the floor plans, also called working drawings, you may see abbreviations like:
NIC: not in contract
BRK: break
FPL: fireplace
As abbreviations may vary, these should also be listed in the drawing legend.
29
What’s another name for working drawings?

Plywood.
34
What types of substrate is used for laminate finishes?
MDF and particleboard.
Particleboard
Dimensionally stable and provides a smooth surface for laminating. Provides impact resistance and strength for gripping screws for constructing panels and casework.
MDF
It is dimensionally stable, so it does not warp, crack, or cup. It has a dense composition that allows for routing but does not hold screws as well as particleboard. It is smoother than particleboard, so more suitable for gloss laminates and finishes. Special fire-resistant MDF is available.
35
Commercial-grade cabinets are most often constructed of panel products with a thickness of?
The majority of a cabinet is built with 3⁄4 in panels including the bottom, sides, and top bracing. The back is typically 1⁄4 in.

In most spaces, a CRI of _______ or higher is acceptable.
0-100; 80.
The higher CRI renders color more naturally.
46
_______ have poor efficacy.
Incandescents.
This means they require a relatively higher wattage for the lumens output. They have a high CRI for rendering natural color and skin tones appropriate for residential uses.
47
All of the following are true about a low voltage lamp EXCEPT?
-Are another class of incandescent lamps.
-Is a semiconductor device that uses solid-state electronics to create light.
-Typically operate at 12V.
-Provide better beam control than a standard incandescent lamp.
Is a semiconductor device that uses solid-state electronics to create light.
Not all low voltage lamps are LEDs. Some incandescent and halogen lamps are designed to operate at a reduced voltage and are also called low voltage lamps.
These lamps operate at a lower voltage than 120V, usually 12V. Because the filaments are thicker, they are also more compact, resulting in smaller lamps and better beam control lamps.
A transformer is required to step down the line voltage. This results in a bulkier luminaire and higher initial cost.
One type of low voltage lamp, a light-emitting diode (LED), is a semiconductor device that uses solid-state lighting that includes organic light-emitting diodes and light-emitting polymers.
48
It is important to ALWAYS round up for calculations with _______ and ________.

HSW - Health, Safety, and Welfare.
Booths and benches have special circumstances- don’t round up.
49
What takes into account the required circulation space needed per tenant, as well as the non-useable area required for partitions, columns, and so on?
Efficiency Factor.
50
What type of facility would have a lower efficiency factor?
A hospital with many small rooms and large corridors.
Building where less space is allotted for corridors and other non-useable areas will have a better efficiency factor.
51
Even if the occupant load of a building space is less than what is shown in table 1006.2.1 (Spaces with one exit or exit access doorway), _______ exits are still required if the common path of egress travel exceeds the limits given in the same table.
2 exits.
52
Are exit access areas of a building protected?
Once a person is safely in an exit, travel distance is not an issue. Because exit access areas are NOT protected, the codes limit how far someone must travel to safety.
53
Maximum travel distances are based on?
The occupancy of the building and whether or not the building is sprinklered.
Max travel distances in IBC table 1017.2.
54
If three or more exits are required in a space, how must these be spaced?
2 exits must be placed the required 1/2 or 1/3 distance apart of the maximum overall diagonal dimension of the building or area being served.
The third or fourth exits must be arranged at a reasonable distance apart so that if one becomes blocked the others will be available.

57
The required minimum widths of exits is determined by multiplying the occupant load factor of _______ for stairways and _______ for corridors and other egress components.
.3 in for stairways and .2 in for corridors - multiply against the occupant load of a space or the total occupant loads in a building/floor.
If more than one stairway, divide the total occupant load.
Remember NOT to have egress widths less than in the IBC.
58
The required stairway widths for stairways serving more than one story are calculated how?
By using the occupant of each story SEPARATELY, rather than the combined occupant load.
59
If doors are part of the required egress width, their _______ must be used, not the width of the door.
Clear width.
For example, a 36” door actually provides 33” of clear width when the thickness of the door is open in the 90° position and the width of the stop are subtracted from the full width.

110
Where should you look first for important project information?
Project Description in the Prac Program.
111
What does a fully sprinklered building in a program tell you about the project?
1) It tells you the travel distance between doors in a space 1/3 if sprinkled.
3) It tells you about ratings for wall partitions - think mixed occupancies or incidental spaces (table 509).
112
If occupants are unfamiliar with a space, what type of space is that considered?
A risk factor which is typically an assembly space.
Since this space is riskier, there are more codes to protect the occupants. This due to assembly spaces having more occupants in a more compact way.
50 or more people = assembly space.
49 or fewer = business space.
750 sqft or more is assembly; 749 or less is business.
113
What is the correct term for a bathroom stall according to codes?
A compartment, whether accessible or not.
Accessible toilet - private room with turning radius, toilet is the room.
Water closet is the fixture.
114
BOMA only calculates glazing to what ceiling height?
8’. If your ceiling is taller than 8’, that does not matter. 50% or more is to the inside of the glazing (4’H or more of glazing).
115
The 10% rule does not apply to what type of space when figuring out accessory spaces?
Storage.
Non-hazardous, plain, type "S" storage spaces are now seen as "the same" classification as the space that it SUPPORTS.
Storage must SUPPORT the primary occupancy of the floor, but there are no area limitations associated with it.
If it does NOT SUPPORT/is not an accessory to the main space, then it is it’s own “occupancy.”
116
What does aggregate mean when it comes to accessory and incidental occupancies?
Aggregate means combined. As far as accessory occupancies are determined for a floor area, the aggregate (or combined) accessory occupancies shall not occupy more than 10% of the floor area of a story.

120
Fire ratings for shaft enclosures:
Less than 4 stories?
4 stories or more?
Rating if penetrating a rated floor?
1 hr rating.
2 hr rating.
If a shaft is penetrating a rated floor, IT MUST BE RATED THE SAME AS THE FLOOR ASSEMBLY. Should never have ratings more than 2 hrs.
121
Are hallways and corridors the same per the codes?
No, corridors are part of egress, think exit access and IBC chapter 10. A hallway is not.
A corridor is an enclosed exit access component that defines and provides a path of egress travel.
122
What is Exit Access?
Exit Access is a portion of a means of egress system that leads from any occupied portion of the building or structure to an exit.
123
When would you need door closers?
When a partition needs to be fire rated, accessibility (such as an accessible toilet compartment where you need privacy - not the door to the whole restroom), when the program specifically requires it.
Fire rated: maintaining the integrity of the overall assembly, needs to return to the original position for smoke and fire control.
124
What does italicized in the IBC mean?
That the definition is in chapter 2.
125
When are accessible and ambulatory compartments required?
Accessible urinals?
At least 1 accessible compartment is required for each restroom. 1 ambulatory compartment is required with 6 or more stalls/urinal combinations.
When 1 urinal is required, 1 accessible urinal is also required.
126
For accessibility, the weight of doors cannot be more than 5 lbs for what types of doors?
Interior doors. Exterior doors do not have weight requirements.
127

131
Watts vs lumens:
Watts is the amount of power needed to power the bulb. Incandescent is inefficient b/c most of the watts used to power it is a small amount while most of the wattage is released/lost as heat.
You pay for wattage, so might as well have a more efficient bulb.
Lumens deals with the brightness of a light. Higher Efficacy = more efficient.
132
Where are smoke detectors required?
Storage (including closets), spaces, rooms, corridors.
133
Are the requirements for outlets the same for both residential and commercial spaces?
No. Residential spaces require outlets at specific distances, commercial requires outlets based on function.

Toilets, showers and tubs, mop sinks etc.
135
Where can supply lines not go through for a fixture?
It cannot go through a door.
136
Plumbing fixtures that have both a floor drain and a supply on a wall need?
A trench to connect the supply for the wall and, an extra trench for the floor drain.
Fixtures with floor drains typically have two trenches or connections.
137
AFCI vs GFCI?
Arch faults happen within the walls with the wires and in j boxes. Lighting between two wires or a broken wire that can start a fire.
GFCI is to protect a person that is plugging something in without being electrocuted. You don’t want to have to be the ground personally.
138
When you have rated doors, when should you use minutes to label a rated door?
