A new school project is being modeled for energy use. The baseline building project has an energy
cost of $225,282 / year. The proposed building has an energy cost of $119,750 / year. How much
additional energy must be saved to earn a point in the Innovation in Design category for
optimizing energy performance?
A: $7,109
B: $2,395
C: $12,641
D: $19,750

参考答案: A

本题解释:
Notes:


Remember, exemplary performance credits are earned through the Innovation in Design category.

The following minimum energy cost savings will earn an additional point in the Innovation in
Design category:


New buildings: 50%

Existing building renovation: 46%


The percent improvement is a calculation of:


100 X (1 - (proposed building performance / baseline building performance) =


In this example the project was a new school. To earn an ID point the project must use 50% less


electricity from the baseline:


$225,282 X 0.50 = $112,641 / year


Currently the project uses $119,750 / year

The project must save an additional:
$119,750 - $112,641 = $7,109 / year


To prove the numbers we can plug in our results.


The proposed building performance that would earn an ID point is $119,750 - $7,109 = $112,641
100 X (1 - ($112,641 / $225,282) = 50%
