A small office building is determined to have 10 FTE female and 10 FTE male occupants. The existing water closets have a flowrate of 2.0 gallons per flush (GPF), and the urinals have a flowrate of 1 GPF. For LEED calculation purposes, what amount of water is used daily as a result of occupants using the restroom?
A: 80 gallons
B: 100 gallons
C: 120 gallons
D: 140 gallons
E: 160 gallons

参考答案: B

本题解释:
Notes:
See “Calculations” section of NC WEc3, Water Use Reduction
Men are assumed to use water closets once a day and urinals twice
Women are assumed to use water closets three times

10 women x 3 water closet uses x 2 gpf = 60 gallons
10 men x 1 water closet use x 2 gpf = 20 gallons
10 men x 2 urinal uses x 1 gpf = 20 gallons

60 gallons + 20 gallons + 20 gallons = 100 gallons
