Which of the following is the primary purpose of the LEED Water Metering credit?
Answer: To support water management and identify opportunities for additional savings
The Water Metering credit supports ongoing water management by tracking consumption data, enabling building operators to identify leaks and savings opportunities.
A LEED project uses harvested rainwater for toilet flushing and irrigation. Which term best describes this water source?
Answer: Non-potable water

Under LEED, which fixture type has a baseline flow rate of 2.2 gpm for private applications?
Answer: Showerheads
LEED v4 sets the showerhead baseline at 2.2 gpm for residential/private applications when calculating water use reduction.
What percentage of landscape area must consist of no-irrigation-required or temporarily-irrigated plants to fully comply with LEED's no-irrigation option?
Answer: 100%
To claim the no-irrigation pathway in LEED's Outdoor Water Use Reduction, 100% of the landscape must require no permanent irrigation after an establishment period.
Which LEED Water Efficiency credit addresses water used in food service equipment such as commercial dishwashers?
Answer: Indoor Water Use Reduction – Process Water
Process water used in food service equipment falls under the Indoor Water Use Reduction credit's process water component in applicable LEED rating systems.
A building's cooling tower uses municipal potable water as makeup water. Which strategy would MOST directly earn the Cooling Tower Water Management credit?
Answer: Using recycled non-potable water as makeup water
Substituting non-potable recycled water for potable municipal water as cooling tower makeup directly addresses the credit's intent to reduce potable water consumption.
In LEED BD+C, what is the baseline annual full-time equivalent (FTE) occupancy assumption used when no actual occupancy data is available for water calculations?
Answer: 8 hours/day, 250 days/year
LEED uses a default of 8 hours per day and 250 working days per year to calculate annual FTE occupancy for water use calculations when actual data is unavailable.
