You may use the LEED v4 version of this credit on v2009 projects. For more information check out this article.Frequently asked questions
If manufacturer documentation is unavailable and the flow/fixture rate is unknown, how would one go about confirming the flow/flush rates of those fixtures?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
We are not able to locate the flow/flush rates of the plumbing fixtures in the project building, so we have decided to test 20% of the fixtures of each fixture type. How do we go about doing that?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
If pre-1993 plumbing fixtures are still in place (i.e. the water closets), but their flush valves have been replaced post-1993, does that count as 'plumbing renovation' or fixture replacement for the purposes of the prerequisite/credit?The answer to this question is available to LEEDuser premium members.

What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
