Exam Questions and CORRECT Answers
The higher the light-to-solar gain ratio, the _______ the room is without adding excessive
amounts of heat
A ) brighter
B ) darker - CORRECT ANSWER - A ) brighter
Light-to-Solar Gain = Visual Transmittance / Solar Heat Gain Coefficient
The higher the light-to-solar gain ratio, the brighter the room is without adding excessive
amounts of heat

block out the hot sun.
A ) TRUE
B ) FALSE - CORRECT ANSWER - A ) TRUE
On a summer afternoon you should keep the draperies closed on all west-facing windows to
block out the hot sun
______________ measures how well a window blocks heat from the sunlight
A ) Solar Heat Gain Coefficient (SHGC)
B ) Visual Transmittance (VT)
C ) Light-to-Solar Gain ratio (LSG)
,D ) Air Leakage (AL) - CORRECT ANSWER - A ) Solar Heat Gain Coefficient (SHGC)
SHGC measures how well a window blocks heat from the sunlight
We have a window with SHGC=0.33 and VT=0.52. What is the LSG?
A ) 0.63
B ) 0.17
C ) 0.85
D ) 1.58 - CORRECT ANSWER - D ) 1.58
LSG = VT / SHGC
LSG = 0.52/0.33 = 1.58
Typically, windows have an R-value ________ the wall.
A ) Lower than
B ) Higher than
C ) Equal to that of - CORRECT ANSWER - A ) Lower than
Typically, windows have an R-value lower than the wall
Condensation Resistance (CR) is expressed as number between 0 and __________
A ) 100
, B)1
C ) 10
D ) 1.2 - CORRECT ANSWER - A ) 100
Condensation Resistance is expressed as a number between 0 and 100
Insolation is a combination of the following words _____.
A ) Instrumental solar insulation
B ) Incident solar radiation
C ) Intricate solar variation
D ) Involved solar saturation - CORRECT ANSWER - B ) Incident solar radiation
The amount of solar radiation reaching the earth is called the insolation. This is a short form for
INcident SOLar radiATION
Which of the following is not a consideration when picking a window?
A ) SHGC
B ) VT
C ) AL
D ) Cp - CORRECT ANSWER - D ) Cp
Solar Heat Gain Coefficient (SHGC), Visual Transmittance (VT), Air Leakage (AL) are
parameters to be considered when picking a window
