A project area is 20,000 sf. The total segment area for the project is 100,000 sf. The design energy cost of the HVAC system is $28,000. The baseline energy cost budget is $30,000. What is the percent reduction of annual HVAC energy use for the project?
A: 18%
B: 14%
C: 33%
D: 7%

参考答案: C

本题解释:
Reference: Energy and Atmosphere Credit, Optimize Energy Performance-HVAC, Calculations, Option 2, S

The formula is:

Reduction =
Baseline Energy Cost Budget - Design Case Energy Cost
Baseline Energy Cost Budget X (Project Area / Total Segment Area)

$30,000 - $28,000 = $2,000

Divide that by:
$30,000 X (20,000 sf / 100,000 sf) = $6,000

$2,000 / $6,000 = 33%
