NCIDQ IDPX & PRAC EXAM
QUESTIONS AND ANSWERS
life cycle cost analysis -
correct answer ✅determines cost of a building component;
accounts for initial cost, financing, operation, maintenance,
disposal, & residual value.
HID and fluorescent -
correct answer ✅two light sources that require the use of a ballast
low voltage lamps -
correct answer ✅can include incandescent, halogen, and LED
lamps that are designed to operate at a reduced voltage; provide
better beam control than a standard incandescent lamp; not
specifically solid-state lighting (LEDs); CAN BE SWITCHED TOGETHER
Illuminance -
correct answer ✅The rate at which light strikes a surface, or falls
on a unit area; is measured in footcandles or in metric - lumens per
square meter or lux, lx.
Luminance -
correct answer ✅Luminous flux per unit of projected area and unit
solid angle leaving a surface, either reflected or transmitted.
,NCIDQ IDPX & PRAC EXAM
QUESTIONS AND ANSWERS
Measured by candela per square meter. Sometimes referred to as
brightness
candela per square meter -
correct answer ✅units used for the measurement and description
of the brightness (foot lamberts) of a direct glare source are
Lumen -
correct answer ✅the amount of light output produced by a lamp
or light source; lamp manufacturers rate their lamps in this unit and
publish catalogs with this information
Candlepower -
correct answer ✅The luminous intensity of a light source,
expressed in candelas.
Footcandle -
correct answer ✅A unit of illumination equal to 1 lumen per
square foot.
,NCIDQ IDPX & PRAC EXAM
QUESTIONS AND ANSWERS
Incandescent, fluorescent, high-intensity discharge, and light-
emitting diodes -
correct answer ✅Four types of light sources
Efficacy -
correct answer ✅Ratio of luminous flux emitted to the total power
input of the source and is measured in lumens per watt;
incandescent is low in this
Incandescent -
correct answer ✅Lamp that consists of a tungsten filament placed
within a sealed bulb containing an inert gas; inexpensive, compact,
easy to dim, and can be repeatedly started without a decrease in
lamp life, and have a warm color rendition; LOW EFFICACY, short
lamp life, and high heat output; can include halogen/MR16 lamps
44in -
correct answer ✅Minimum exit corridor width in commercial
construction
application for and certificate for payment -
correct answer ✅What document(s) are used to approve the
release of funds for furnishing a project?

shipping.
sales agreement/contract proposal, purchase order, certificate of
payment (from client), acknowledgement, bill of lading, packing list
-
correct answer ✅Order of the paperwork necessary during the
procurement process for furniture
after the designer has completed research and narrowed the search
for furniture to a few specific types; helps the designer and client
make a final decision -
