Intent
To reduce potable water consumption and the associated energy consumption and carbon emissions required to treat and distribute water, and to preserve potable water resources through an efficiency-first approach.
Requirements
Points are awarded based on total potable water consumption during a 12-month reporting period using the metric of gallons per square foot per year (or liters per meter per year). To earn 1 point, meet the baseline water use intensity threshold for the applicable space type as shown in Table 1. To earn additional points, demonstrate a percent reduction from the baseline water use intensity threshold as shown in Table 2.

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.
