daylighting design can save a typical school how much per year in
energy savings:
a. $40,000 (54 cents per sq ft)
b. $16,000 (32 cents per sq ft)
c. $7,500 (23 cents per sq ft)
d. $1,750 (8 cents per sq ft)

2. Daylighting can significantly reduce the costs of energy consumption of artificial lighting which, according to the U.S. Department of Energy, accounts for as much as how much in most commercial and institutional buildings:
a. 10% to 20%
b. 25% to 35%
c. 40% to 50%
d. 50% to 75%

3. Daylight produces less heat per unit of illumination than many
artificial lights.
a. true
b. false

4. Match the term with the definition.
a. Visual transmittance (TV)
b. Light-to-solar gain ratio (TV divided by SHGC)
c. U-value
d. R-value

1. Insulating value of a material .
2. Index of how much light a system provides in proportion to the solar gain produced.
3. Measure of the portion of visible light that passes through a window.
4. Expresses how much energy a glazing system transfers by conduction and convection.

5. Glazing systems with high visual transmittance (TV) values (0.7 to 0.9) provide good natural light.
a. true
b. false

6. Which systems provide more significant solar gains? Those with high
(0.7 to 0.9) solar heat gain coefficient (SHGCs) or those with low values (0.2 to 0.4 range)?
a: high
b. low

7. A system with a light-to-solar gain ratio (visual transmittance value divided by the solar heat gain coefficient) greater than 1 is providing which:
a. more heat than light
b. more light than heat
c. equal amounts of heat and light

8. Designers can consider vision glazings and daylight glazings comparably because they perform similar functions.
a. true
b. false

9. Fill in the blanks: As a general rule, select a vision glass with a visible transmittance value between ________ percent and a daylighting glass with a visible transmittance value of __________ percent.
a. 10-20 (vision) and 60-70 (daylighting)
b. 20-30 (vision) and 50-60 (daylighting)
c. 50-60 (vision) and 20-30 (daylighting)
