A new school is planning to install a geothermal electric system. This system will produce 15,000 kWh of electricity per month. A whole building simulation has determined the building’s annual energy cost to be $310,000. The local cost for electricity is $0.07/kWh. How many points will this project be eligible for under Energy and Atmosphere credit, On-Site Renewable Energy?
B: 1
C: 2
D: 3
E: 5

参考答案: C

本题解释:
Notes：
See the ‘Requirements’ section of EAc2, On-Site Renewable Energy.

The geothermal electric system produces (15,000 kWh/month) x (12 months/year) = 180,000 kWh/year

(180,000 kWh/year) x ($0.07/kWh) = $12,600/year (this is the value of the energy produced by the system)

$12,600/$310,000 = .04 or 4% of the total building energy cost is produced by the geothermal electric system

Producing 4% of the building’s total energy (by cost) will earn the project 2 points for this credit.
