it? Draw a quick sketch of the site. (Use your imagination.)
14. You want to analyze what must be done to obtain LEED 2009 SS Credit 5.2 with the lot in
Exercise 8. The local code requires a minimum of 40 percent open space. Do you meet the LEED
open-space requirement with the existing layout? If not, how much additional area would need to
be dedicated to open space to obtain this credit, and what areas would you suggest that you use
for it? Draw a quick sketch of the site. (Use your imagination.)
15. You wish to get credit for the heat island effect by using a light concrete paving material for part

of the paved surfaces on a lot. If the parking areas cover 20,000 ft and there is an additional 4000 ft of
walks and drives, what minimum area of these paved surfaces must be the lighter paving material?

16. If you instead provide tree shading for 2000 ft of the parking area in Exercise 15, what area in square
feet, other than the shaded areas, must have the higher albedo surface to still be eligible for this credit?

17. A site has 20,000 ft of land covered by buildings and hardscape. It also has 21,000 ft of land
covered by landscaping. Assume that the average rational runoff coefficients for the development
footprint and the landscaped areas are 0.95 and 0.30, respectively. What is the percent imperviousness?
What is the percent impervious? Which option is the appropriate one in SSc6.1? Why?

18. Two buildings are being built on a lot. One is a 2000 ft tarred flat roof storage building. The other
is an office building complex with a 4:12 pitch (33 percent slope) with a white coating on a metal roof.

The actual sloped area of the roof on the office complex is 6400 ft . Will you be eligible for SSc7.2?
19. Go outside your classroom building and itemize all the light fixtures that you see. Incorporate
these into the categories in Table 2.8.1. Sum the wattages for each category in Table 2.8.1. If wattages
are unknown, then use estimated wattages or those suggested by your instructor.

20. Go to your favorite fast food restaurant. Itemize all the exterior light fixtures that you see.
Incorporate these into the categories in Table 2.8.1. Sum the wattages for each category in Table 2.8.1.
If wattages are unknown, then use estimated wattages or those suggested by your instructor.
21. Go to your bank. Itemize all the exterior light fixtures that you see. Incorporate these into
the categories in Table 2.8.1. Sum the wattages for each category in Table 2.8.1. If wattages are
unknown, then use estimated wattages or those suggested by your instructor.
