A Core and Shell building is 480,500 gross sf. The usable area of the building is 418,035 sf. According to the Commercial Buildings Energy Consumption Survey (CBECS), the building is expected to consume 11.7 kWh/sf/yr. How much renewable energy must be purchased to qualify for Energy and Atmosphere credit, Green Power?
A: 295,147 kWh
B: 511 ,588 kWh
C: 590,295 kWh
D: 843,278 kWh

参考答案: C

本题解释:
Notes:
See the ‘Calculations’ section of EAc6, Green Power.

Determine the percentage of core and shell space:
((480,500 gross sf) - (418,035 usable sf)) / (480,500 gross sf) = 0.13 or 13%
If the result is less than 15%, use 15% for the calculations.
15% of 480,500 gross sf = 72,075 sf

72,075 sf x 11.7 kWh/sf/yr = 843,278 kWh/yr is the default annual electricity consumption

Required Green Power:
843,278 kWh/yr x 35% x 2 year contract = 590,295 kWh
