Intent

To increase water efficiency within the tenant space to reduce the burden on municipal water

Requirements

Employ strategies that in aggregate use 20% less water than the water use baseline calculated for the tenant space (not including irrigation). BUILDING WATER USE Calculate the baseline according to the commercial baselines outlined below. Calculations are based on estimated occupant usage. Include only the following fixtures and fixture fittings (as applicable): water closets, urinals, lavatory faucets, showers, kitchen sink faucets, and pre-rinse spray valves. [Europe ACP: Water Use Baseline] [view:embed_resource==2600975]

AND
COMMERCIAL PROCESS WATER USE Employ strategies that in aggregate use 20% less water than the water use baseline calculated for commercial equipment performance requirements as listed in the following table. Base the calculations on estimated occupant usage. Include only the following fixtures (as applicable): clothes washers, dishwashers, ice machines, food steamers, and combination ovens. Exemptions from calculations:
  • Appliances and equipment that use water for human consumption may be excluded. Examples: bread misters, produce misters, soda machines, coffee-making machines, and fixtures used to fill sinks for washing produce.
  • Equipment, appliances, fixtures, and fittings not covered by the Energy Policy Act of 1992 (EPAct 1992), do not contribute toward the retail process, and are not commercially rated may also be excluded. Example: a residential dishwasher in an employee break room.
  • Fixtures whose flow rates are regulated by health codes may be excluded. Example: fixtures used for filling dishwashing sinks in which water must be maintained at a certain temperature.
[view:embed_resource==2600977] For equipment not listed in the above tables, the project team may propose performance baseline requirements, with documentation supporting the proposed benchmark.

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.
