A Core and Shell project in Nevada has a wind energy system added to the roof.
According to the US DOE’s Commercial Buildings Energy Consumption Survey the
estimated electricity the project will use will be 1,000,000 kWh/year. Energy costs in the
area are $0.08/kWh. What must the wind system produce to earn 4 points for Energy and
Atmosphere Credit, On-Site Renewable Energy?
A: $8,000 of energy
B: 10,000 kWh of energy
C: 20,000 kWh of energy
D: $800 of energy

参考答案: D

本题解释:
Notes:
To earn four points, a Core and Shell project must get 1% of the buildings annual energy cost
from on-site renewable energy.
On-site renewable energy is calculated as a percent of the building\'s annual energy cost. The
correct answer is 1% of the cost, not 1% of the total energy.
The estimated energy use is 1,000,000 kWh from the CBECS database. This multiplied by the
cost per kilowatt hour gives an annual energy cost of $80,000.
$80,000 X 1% (0.01) = $800.00
