The total area for a dentist’s office is 18,522 SF. The gross lighting floor area for a dentist’s office is 18,340 sf. The lighting power density for the space is 1.1 watts/sf. What is the installed interior lighting power allowance using the building area method?
A: 20,374 watts
B: 18,522 watts
C: 18,340 watts
D: 20,174 watts

参考答案: D

本题解释:
Reference: Energy and Atmosphere Credit, Optimize Energy Performance-Lighting Power, Calculations

For the building area method use this equation:

Installed interior lighting power allowances (watts) = gross lighting floor area (sf) X building area type lighting power density (watts/sf)

18,340 sf X 1.1 watts/sf = 20,174 watts
