Under LEED BD+C, which of the following is an example of an 'alternative water source' that can reduce potable water demand?
Answer: Municipally supplied reclaimed water used for toilet flushing
Municipally supplied reclaimed (recycled) water is a recognized non-potable alternative water source for flushing fixtures.
What does a 'water budget' approach in LEED landscape design involve?
Answer: Calculating the maximum allowable irrigation volume based on plant species, climate, and area, then designing to stay within that limit
A water budget sets an evapotranspiration-based limit on irrigation volume, guiding plant selection and system design to reduce outdoor water use.
Which LEED credit rewards projects that achieve zero potable water use for irrigation?
Answer: Outdoor Water Use Reduction at the maximum credit threshold
Achieving zero potable water for irrigation earns the maximum points available under the Outdoor Water Use Reduction credit.
A hospital project team notes that sterilization equipment uses significant amounts of water. Under LEED, this is classified as what type of water use?
Answer: Process water (non-regulated)
Sterilization equipment is a process water use, classified as non-regulated because it is not governed by standard plumbing fixture codes.
What role does the 'Evapotranspiration Rate' (ETo) play in LEED outdoor water calculations?
Answer: It represents the reference water loss from soil and plants, used to calculate baseline irrigation demand
ETo is the reference evapotranspiration rate for a region, forming the basis of the irrigation water budget calculation in LEED.
In a LEED project, condensate recovered from air handling units is best categorized as which type of water?
Answer: On-site alternative water source suitable for non-potable uses
HVAC condensate is a clean on-site alternative water source that can be collected and reused for toilet flushing, irrigation, or cooling tower makeup.
Which LEED Water Efficiency strategy also benefits the Energy & Atmosphere category by reducing energy consumed for water heating?
Answer: Reducing hot water fixture flow rates to lower domestic hot water demand
Lower-flow hot water fixtures reduce the volume of water that must be heated, directly cutting domestic hot water energy consumption.
