Exterior lighting planned for a commercial building
Parking lot 20,000 sq. ft
8' wide walks 300 linear ft.
main entries 2 at 6' wide
atm 1 location
considering both nontradable and tradable services what is the total lighting power density for this building.
I can not for the life of me come up with the correct answer for this question.
P.S. the question is out of the 2009 study companion. They give you the answer nad the code ref. but do not explain how they got the answer.
If any one could help it would be appreciated.
