Projects in a campus environment For campus environments or projects that receive cooling from a district cooling system, projects meet the requirements of Path 2 if the district system meets the reduction thresholds. Projects should consider working with their utility provider to determine compliance at the district system level.

PATH 3. PROCESS WATER USE

Projects pursuing this path must demonstrate that process water use exceeds 10% of the total building-regulated water use, excluding cooling water.

Using alternative water sources, such as captured condensate from air handling units, reduces reliance on fresh water for process systems. Diversifying the water sources on a project site builds resilience in buildings. This allows projects to divert freshwater for human consumption instead of processes during a water crisis.

When selecting the alternative water source, ensure that the quality of the water is sufficient for its intended use and that the local AHJ allows that alternative water source, per local codes and standards.

Option 6. Water Reuse

Option 6 provides two paths to achieve points for water reuse strategies. Projects must choose a single path and cannot combine these paths for more points.

Path 1 rewards projects that install systems allowing the future supply of reclaimed or alternative water sources to at least one specific end use. Path 2 rewards projects that implement water reuse strategies on-site and/or use reclaimed or alternative water supplied by municipalities.

The project must include water reuse for at least one end use listed below. Implementing alternative or reclaimed water sources for as many systems as possible significantly contributes to potable water conservation efforts.

• Irrigation

• Flush fixtures (urinals, water closets)

• Make-up water systems (including cooling towers and boilers)

• Other process water systems
