To minimize potable water use inside buildings, the installation of which fixtures is recommended?

The recommendation to install high-efficiency fixtures is rooted in their ability to significantly reduce water consumption while maintaining the performance standards required for effective use. High-efficiency fixtures, such as low-flow toilets, faucets, and showerheads, are specifically designed to minimize potable water use without compromising user experience. This aligns with LEED's goals for sustainable building practices and water conservation initiatives.

For instance, high-efficiency toilets typically use 1.28 gallons per flush or less compared to conventional models that use up to 3.5 gallons. Similarly, high-efficiency showerheads and faucet aerators are designed to deliver a powerful flow while using less water, which contributes to overall water savings throughout the building.

In contrast, standard faucet aerators, conventional toilets, and traditional showerheads may not offer significant water savings and could lead to higher potable water consumption. The emphasis on high-efficiency fixtures supports broader efforts to decrease demand for freshwater resources, reduce utility costs, and promote environmentally responsible building practices.
