LEED Green Associate (LEED GA) — Question 71

A building owner has set a goal of reducing water use by 20% for the upcoming year. Which of the following strategies will aid in reducing indoor water demand to achieve the water reduction goal set by the owner?

Answer options

• A. Installing dual-flush toilets
• B. Collecting rainwater in cisterns
• C. Installing building-level water meters
• D. Using potable water for flush functions

Correct answer: A

Explanation

The correct option, A, involves installing dual-flush toilets, which are designed to use less water per flush and can significantly reduce indoor water demand. Options B and C, while beneficial for water management, do not directly reduce indoor water usage; option D contradicts the goal of reducing water use by suggesting the use of potable water for flushing.
