What type of label must indoor plumbing fixtures have to meet LEED standards?

To meet LEED standards for water efficiency, indoor plumbing fixtures must carry the WaterSense label. The WaterSense program, managed by the U.S. Environmental Protection Agency (EPA), identifies products that are water-efficient and perform well. Fixtures that bear this label are certified to use at least 20% less water than conventional models without sacrificing performance, which aligns with LEED's goal of reducing water use in buildings and promoting sustainable practices.

The WaterSense label is particularly significant as it not only indicates efficiency but also allows for consistency and reliability in performance, making it easier for builders and consumers to choose products that contribute to water savings. This helps buildings achieve higher ratings under LEED, especially in the Water Efficiency category, where optimizing water usage is a critical component of sustainable design.
