Relating to water efficiency in LEED.

Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to “use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Water Efficiency | U.S. Department of Energy]
