The project team for an elementary school did not perform a whole building simulation for Energy and Atmosphere Credit, Optimize Energy Performance. Instead the team is estimating 6.6 kWh/SF/year of energy use for the 98,750 SF building. The project team is expecting to pay $0.07/kWh for renewable energy. How much energy must be purchased to earn Energy and Atmosphere Credit, Green Power?
A: $15,967
B: 228,112 kWh
C: 456,225 kWh
D: $31,935

参考答案: C

本题解释:
Notes:
Reference: Energy and Atmosphere Credit, Green Power, Requirements
To earn this credit the team must purchase 35% energy from renewable energy sources.
The team must find the total annual energy use.
6.6 kWh/SF/yr X 98,750 = 651,750 kWh/yr
651,750 kWh/yr X 35% = 228,112 kWh/yr
The project must purchase this amount for two years.
228,112 kWh/yr X 2 = 456,225 kWh is the amount that must be purchased to earn the Green Power credit.
Green power purchases are based on the quantity of power purchased not on cost.
