What is a typical requirement for restroom fixtures under LEED?

Restroom fixtures in LEED projects are designed to promote water efficiency and conservation, which aligns with the overall sustainability goals of the certification. High-efficiency models significantly reduce water consumption compared to standard fixtures, making them a key requirement for achieving LEED credits in water efficiency.

By implementing high-efficiency fixtures, projects can greatly decrease the amount of water used in restrooms, which not only aids in resource conservation but also potentially lowers utility costs for building occupants. Moreover, this focus on efficiency supports the broader objectives of LEED, including minimizing the environmental impact of water usage and enhancing indoor environmental quality.

The other choices suggest minimum flow rates or flush rates that do not align with the intent of promoting high-efficiency models specifically. The emphasis is on selecting fixtures that optimize water use rather than just meeting a specified flow rate or flush volume.
