This credit rewards projects that exceed the requirements specified in the indoor water use reduction prerequisite. Additional points are earned for every 5% of additional savings over the prerequisite requirement of 20%, up to 50% savings. An additional Innovation point can be earned for exemplary performance for projects that achieve savings of 55% or greater. Core & Shell projects follow the same point structure; however, achievement is capped at 40% savings.

What’s New in LEED v4.1

• Points for Core & Shell projects are now broken out separately. Up to four points can be earned by CS projects, reduced from the six points available under v4.

Should I upgrade?

Core and Shell projects that can reach savings beyond 40% will earn more points under v4. There’s no reason for other project types to do a one-off credit upgrade.
