How can east/west glass doors and windows be effectively shaded to reduce solar gain?
Fully shaded top-to-bottom
What is the main benefit of using Translucent Insulation Aerogel in a room?
Excellent insulating properties with limited light transmission
Why might a designer choose to use an R-13 foam-filled solid exterior door instead of a west-facing window?
Better summer thermal performance
Which material has the lowest density of any solid material mentioned in the text?
Translucent Insulation Aerogel
What feature of a translucent wall made with Aerogel and fiber-reinforced plastic allows light to pass through?
Translucent nature
How is transparent insulation used effectively to provide natural daylight?
With minimal heat transfer through vertical walls or sawtooth roofs
What can be useful additions to a building to reduce heat transfer and improve daylighting, as suggested in the text?
Adding interior shading or external shutters
What is the purpose of glare control for equator-facing glass in rooms with a low winter sun?
To reduce the heat gain from the sun
What material is described as a 'Lambertian Diffuser' in daylighting?
Clear glass windows
Why are skylights considered a better choice than windows for daylighting?
Skylights are more cost-effective
What factor affects the thermal performance of skylights, particularly in cool climates?
The color of the skylight
What percentage of floor area is usually recommended as the optimum number of skylights for daylighting?
2-4%
Why is white acrylic considered advantageous for skylights?
It absorbs most of the transmitted light
How does stratification impact the thermal performance of skylights?
It reduces heat loss in cool climates
What effect can changes made to the building envelope to deliver daylight to interior spaces have on a building's heating and cooling loads?
Minimize both winter heat loss and summer heat gain
What should be avoided in daylighting to prevent excessive heat gain?
Overlighting
Why must daylight be efficiently distributed within a building?
To provide illuminance at desired levels

Minimizes both winter heat loss and summer heat gain
How can direct solar gain during cooling months be minimized?
Using overhangs and exterior devices
Which factor makes daylight generally preferred over electric light sources?
Excellent color rendering due to spectral composition
What is a potential consequence of overlighting in a building?
Excessive heat gain
