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 100,000 kWh/year. Energy costs in the area are
$8.15/kWh. How much energy must the wind system produce to earn 4 points for Energy
and Atmosphere Credit, On-Site Renewable Energy?
A: $57,050
B: $8,150
C: 4,000 kWh
D: 1,000 kWh

参考答案: B

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 100,000 kWh from the CBECS database. This multiplied by
the cost per kilowatt hour gives an annual energy cost of $815,000.
$815,000 X 1% (0.01) = $8,150
