A Core and Shell project is 213,000 gross SF of which 183,180 SF is considered usable. The building is expected to consume 11.7 kWh/SF/yr. How much energy must be from renewable sources to earn points for Energy and Atmosphere Credit, Green Power?
A: 122,113 kWh
B: 244,225 kWh
C: 261,671 kWh
D: 130,835 kWh

参考答案: C

本题解释:
Notes:
To earn two points for EA Credit 6, the core and shell project must purchase 35% of the building electricity from renewable sources for two
years.
Additionally, Core and Shell projects only account for energy used for the Core and Shell square footage, but it must be a minimum of 15%
of the building total gross square footage. Calculate Core and Shell square footage, (GSF-USF) / (GSF) x 100.
213,000 SF - 183,180 SF = 29,820 SF / 213,000 SF = 14%, but the credit requires we use 15%.
The Core and Shell square footage is less than the minimum, so use the 15% minimum number in the calculation.
213,000SF X 0.15 = 31,950 SF
31,950 SF X 11.7 kWh/SF = 373,815 kWh/yr is the default annual electricity consumption
The project must buy 35% of this amount for two years.
373,815 X 0.35 X 2 = 261,671 kWh
