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 alternate baseline energy cost budget is $34,000. What is the percent reduction of annual HVAC energy use for the project?
A: 12.5%
B: 15.8%
C: 20%
D: 17.6%

参考答案: D

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

The equation is:

(Alternative baseline energy cost budget - design case energy cost) / Alternative baseline energy cost budget

($34,000 - $28,000) / $34,000 = 17.6%
