Requirements

OPTION 1: Reduce by 50% (2points)
Reduce potable water consumption for irrigation by 50% from a calculated midsummer baseline case or using the month with the highest irrigation demand. Reductions must be attributed to any combination of the following items:
  • Plant species, density and microclimate factor
  • Irrigation efficiency
  • Use of captured rainwater
  • Use of recycled wastewater
  • Use of water treated and conveyed by a public agency specifically for nonpotable uses
Groundwater seepage that is pumped away from the immediate vicinity of building slabs and foundations can be used for landscape irrigation to meet the intent of this credit. However, the developer or owner must demonstrate that doing so does not affect site stormwater management systems.

OR

Option 2: No potable water use or irrigation1 (4 points)
Meet the requirements for Option 1.

AND

PATH 1
Use only captured rainwater, recycled wastewater, recycled graywater or water treated and conveyed by a public agency specifically for nonpotable uses for irrigation.

OR

PATH 2
Install landscaping that does not require permanent irrigation systems. Temporary irrigation systems used for plant establishment are allowed only if removed within a period not to exceed 18 months of installation.

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.
