LEED Green Associate (LEED GA) — Question 26

Which is an example of a low-cost Water Efficiency strategy?

Answer options

• A. Install new flush valves or flow restrictors
• B. Install subsurface cisterns to collect stormwater
• C. Use only compostable toilets throughout the facility
• D. Incorporate an on-site blackwater treatment system

Correct answer: A

Explanation

Installing new flush valves or flow restrictors is a cost-effective way to improve water efficiency by reducing the amount of water used per flush. The other options, such as subsurface cisterns, compostable toilets, and on-site blackwater treatment systems, typically involve higher initial investments and are not classified as low-cost strategies.
