Read the first 7 (Leadership in Energy and Environmental Design Certification) Water Efficiency flashcards as text

  1. A landscaping design uses only native and adaptive plants with no permanent irrigation system. Which LEED pathway does this approach satisfy?

    Answer: Option 2: No irrigation required

    LEED's Outdoor Water Use Reduction credit includes an option for projects that require no permanent irrigation after an establishment period, using native or adaptive plants.

  2. Which LEED rating system does NOT include a standalone Outdoor Water Use Reduction credit because outdoor water use is not applicable?

    Answer: ID+C: Commercial Interiors

    LEED ID+C: Commercial Interiors does not include an Outdoor Water Use Reduction credit because tenant fit-out projects typically have no control over exterior landscaping.

  3. What does 'makeup water' refer to in the context of cooling tower operations under LEED?

    Answer: Water added to replace losses from evaporation, drift, and blowdown

    Makeup water replenishes the water lost from a cooling tower through evaporation, drift (misting), and intentional blowdown to control mineral concentration.

  4. A LEED project team wants to reduce water use in their medical sterilization equipment. Under which credit category should they document this reduction?

    Answer: Indoor Water Use Reduction – Process Water

    Water used in medical sterilization equipment is classified as process water, and its reduction is documented under the process water component of the Indoor Water Use Reduction credit.

  5. What is the primary reason LEED requires 'cycles of concentration' management in cooling towers?

    Answer: To reduce the frequency of blowdown and conserve water

    Managing cycles of concentration (the ratio of dissolved solids in blowdown vs. makeup water) reduces the frequency of blowdown, directly conserving water in cooling tower operations.

  6. Under LEED v4 BD+C, which of the following best describes a 'transient occupant' for the purpose of water use calculations?

    Answer: A visitor or customer who spends less than a full workday in the building

    Transient occupants are visitors or customers who spend less than a full working day in the building and are assigned a lower water use factor than full-time equivalent (FTE) occupants.

  7. Which US EPA program's WaterSense label is referenced by LEED as a benchmark for high-efficiency plumbing fixtures?

    Answer: WaterSense

    EPA WaterSense is the federal labeling program that certifies high-efficiency water fixtures, and LEED references WaterSense specifications as a benchmark for fixture performance.
