Basics of Daylighting in a Green Environment
The use of natural sunlight, known as daylighting, to illuminate a building can save energy, reduce operating costs, create visual appeal, and enhance occupant health and productivity. The U.S. Green Building Council Leadership in Energy and Environmental Design (LEED™) rating system encourages the use of daylighting to achieve high performance buildings. This course provides an introduction to the use of daylighting in commercial spaces. The course objective is to show why daylighting should be considered, the basic guidelines of using daylighting and some words of caution when using certain daylighting techniques.

  1. Introducing daylighting into a space:
    1. Always reduces energy costs.
    2. Never reduces energy costs.
    3. Can reduce energy costs.
    4. Never increases energy costs.
  2. 'Efficacy' is a measure of:
    1. The amount of daylight available at a certain date and time.
    2. How many lumens a source contributes to a space compared to the watts it uses.
    3. The brightness of a light source.
    4. None of the above.
  3. A project location is most compatible with the use of daylight where the differential between interior and exterior temperatures is:
    1. Large
    2. 18 Degrees
    3. Small
    4. Doesn't matter
  4. Which of the following is typically NOT part of good daylighting:
    1. Control of the daylight with architectural features
    2. Maximizing the amount of direct sunlight into a space
    3. Minimizing the use of electric lights when daylight is available
    4. Using daylight as the primary source of illumination
  5. Direct sunlight might be best used to light a:
    1. Lobby
    2. Computer classroom
    3. Private office
    4. Machine shop
  6. Daylight can be best utilized when the building footprint:
    1. Is narrow and runs East-West
    2. Is narrow and runs North-South
    3. Is as close to square as possible
    4. Doesn't matter
  7. In general, when using daylighting, interior room surfaces should be:
    1. Shiny and light colored
    2. Diffuse (matte) and light colored
    3. Shiny and dark colored
    4. Diffuse (matte) and dark colored
  8. When using a computer monitor in a space with daylighting, it is best to:
    1. It doesn't matter.
    2. Sit facing the window.
    3. Sit facing away from the window.
    4. Sit facing parallel to the window.
  9. If there were windows on all four sides of a building, where would you put the service areas (e.g. copy room):
    1. Interior, away from the windows
    2. East side
    3. South side
    4. West side
  10. When daylighting, one must carefully control the:
    1. Direct sunlight
    2. Light from the sky
    3. Sunlight reflecting off of nearby rooftops
    4. All of the above
  11. Skylights operate best when the building footprint:
    1. Is narrow and runs East-West
    2. Is narrow and runs North-South
    3. Is as close to square as possible
    4. Doesn't matter
  12. Skylights provide more uniform lighting when the skylight well is:
    1. Deep
    2. Shallow
    3. Doesn't matter
    4. Uses dark surfaces
  13. Sizing the skylight properly depends on the:
    1. Electric lighting to be used
    2. Heating and cooling to be used
    3. Occupancy of the space
    4. All of the above
  14. Tubular skylights are most likely to be used in:
    1. A private office
    2. A Warehouse
    3. A cold climate
    4. The bottom floor of a multi-story building
  15. A single, tubular skylight will sufficiently cover an area of about:
    1. 10 sq.ft
    2. 100 sq.ft
    3. 1,000 sq.ft
    4. 10,000 sq.ft
  16. Light, in general, is most abundant from a window facing:
    1. East
    2. North
    3. South
    4. West
  17. Light, in general, is most uniform from a window facing:
    1. East
    2. North
    3. South
    4. West
  18. In determining about how far out from a window daylight will reach into a space, one should multiple the height of the window by:
    1. 1.5
    2. 2.5
    3. 3.5
    4. The width of the window
  19. In general, it is best to bring daylight in from a:
    1. Low angle
    2. 25 degree angle
    3. High angle
