What are the major changes in the water credit category from LEED 2009 to LEED v4?
LEED v4 includes:

  • A shift to more performance-based requirements and category as a whole
  • New prerequisites: building-level water metering (BD+C, O+M, Homes/Midrise), outdoor water use reduction (BD+C)
  • Watersense labeling
  • Further addresses appliance and process water
  • Updated baselines and thresholds

Can savings in process water qualify for credits?
Yes. This is a major addition to v4. Process water is required to be included in the Indoor prerequisite and credit, in particular. See “Appliance and process water use” requirements in the prerequisite. By saving process water, you will achieve the prerequisite and can achieve more points in the credit.

Regarding process water and non-process water, is there a kind of water that is not included into water reduction?
Water uses: anything not listed in the Indoor prerequisite (excluded: appliances and equipment that use water on materials intended for human consumption; fixtures whose flow rates are regulated by health codes, like regulated medical equipment)
Types of water: not really. All types (graywater, blackwater, potable, etc) are addressed in some way, either directly or indirectly. Wastewater is addressed in a pilot credit (BD+C and ID+C).

Are there regional or geographic considerations?
A lot LEED v4 was written as a global rating system. There are many ACPs specific to different regions, and guidance within each credit that covers any other regional/geographic issues. Also are Regional Priority Credits for countries that emphasize important credits/issues in that country. We work with the International Roundtable on anything with geographic significance or unique regional circumstances.
