What does it cost?
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.

Can automated-maintenance urinals be considered "waterless" for the purposes of WE prerequisite and credit Indoor Water Use Reduction?
Yes, automated maintenance urinals with water use not to exceed 150 gallons (568 liters) annually can be considered as waterless urinals for the purposes of credit achievement calculations in LEED v4 WE prerequisite and credit Indoor Water Use Reduction. Do not include the volume of water used by these urinals in the LEED v4 Indoor Water Use Calculator (they can be excluded, or considered to have a water use of 0 gallons/liters). Projects must also submit manufacturer documentation showing the annual volume of water used by the urinals.
