Q practice Flashcards
gross area
is floor area construction
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
usable area
s the floor area used by the tenant — the actual space taken up by furniture and people.
net area plus the circulation area
occupant area
f a space is the total portion of a building being “actively used by a tenant.” This term is NOT to be confused with the term occupant load used throughout building codes.
Rentable area
occupancy area x load factor

Trimmer:
A wood member in a floor or roof used to support a header, used when creating openings.
If soils are weak or poor surface conditions are encountered when designing for a building’s foundation, column like shafts are installed (drilled and filled with concrete, power driven) to depths to reach acceptable supporting stratum. These are:
piles
All-air systems
The air is blown across the cold evaporator coil in an all-air system and delivered to the rooms that require cooling via ductwork. Air systems can cool, heat, ventilate, filter, and dehumidify the air. Air-based HVAC systems use fans to create a moving current of air. Th
Single-duct system with CAV
The single-duct system is a one-zone system. A separate supply duct and the air-handling unit are required for each zone. This system is used for small or medium-sized buildings with few zones.
VAV system
This single-duct system can have many zones. But VAV systems cannot heat one zone while cooling another, so they are cooling-only systems. A separate heating system can be used with the VAV system. It has a low initial cost and low energy usage. It can be used for almost every building type.
Terminal reheat system (CAV)
Instead of VAV boxes, this system has terminal reheat boxes that reheat previously cooled air. The zone with the greatest cooling load determines how much air is cooled for the entire building.
Terminal reheat system (VAV)
the terminal reheat box also controls air volume. Varying the volume of the supply air manages the temperature. The reheat function is used only when some space needs heating while the others all need cooling.
Fire damper:
A device placed in a duct that is designed to automatically close when subjected to a certain increase in temperature or with the detection of smoke.
fire-rated dividers
must be installed to limit the horizontal spread of smoke and fire
Study parts of a stair
balusters
the vertical components that hold the handrail on a stairway and are spaced to prevent people from falling through.

What outlets are not included
GFI this includes outlets in the walls above the counter, outlets in the side of a base cabinet, and outlets required at the island and peninsular counters.
It does not include standard‐height wall outlets (e.g., 15 inches [380 mm] above the floor) adjacent to the counter or outlets installed for built‐in appliances such as a garbage disposal, refrigerator, or microwave, or range. However, since 2014 NEC requires a GFCI outlet for the dishwasher.
Diffusers
have directional fins at different angles (sometimes adjustable) to distribute the air throughout the space.
Registers
(in the floor or wall) can be open, closed, or adjusted somewhere in-between.
In residential outlets should be no farther then what from a wall

Standard dimmers
are for incandescent lamps. The ratings range from 600 watts to dimmers that are rated up to 2000 watts.
Dimmers for low voltage lamps and fixtures
such as halogen or LED. There are two kinds: dimmers rated for magnetic transformers and dimmers rated for electronic transformers. They are usually rated in volt‐amps (VA), which are roughly the same as watts.
Magnetic‐rated dimmers are rated at least 600 VA, and electronic‐rated dimmers are rated at least 325 VA.
Dimmers for fluorescent lamps.
To dim fluorescent lamps, it is necessary for the fixtures to have dimming ballasts. The dimmer needs to be designed to operate with the specific dimming ballast being supplied.
LED lighting Dimmers
LEDs require special dimming circuits, but most are designed to connect to a low voltage or fluorescent dimmer. Color changing LED lights require specialized controls.

CAC ceiling attenuation class
refers to ceiling tiles ability to reduce sound transmission from one room to another when the rooms share the same plenum space.
NRC
measures the ability of a wall or ceiling to absorb airborne sound, not about the transfer through the assembly. It rates the noise level of the interior space, not the sound transfer.
SAC (CA)
coefficient of absorption is used to evaluate the sound absorption efficiency of materials.
