Intent

To reduce indoor water consumption.

Requirements

Nonresidential buildings, mixed-use buildings, and multifamily residential buildings four stories or more
For new buildings and buildings undergoing major renovations as part of the project, reduce indoor water usage by an average of 20% from a baseline. All newly installed toilets, urinals, private lavatory faucets, and showerheads that are eligible for labeling must be WaterSense labeled (or a local equivalent for projects outside the U.S.). For the fixtures and fittings listed in Table 1, as applicable to the project scope, reduce water consumption by 20% from the baseline. Base calculations on the volumes and flow rates shown in Table 1. The design case is calculated as a weighted average of water usage for the buildings constructed as part of the project based on their floor area.

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.
