PATH 1. REUSE-READY SYSTEM

Path 1 rewards a project for preparing for a future transition to water reuse systems. Planning for water reuse systems early in design allows project teams to optimize solutions for the greatest impact. Through this process, teams determine strategies that reduce the demand and consumption of potable water use in the building and on the project site. The use of reclaimed or alternative water sources allows projects to reduce potable water for end uses not intended for human consumption, such as water closet flushing and make-up water for process systems.

Designing for future infrastructure Including reclaimed or alternative water supply infrastructure allows for an easier transition when sources become available for public use. The inclusion of these systems in new construction projects also results in economic benefits. Planning for future water treatment equipment enables projects to efficiently design the equipment room to allow for future equipment, which reduces long-term costs to integrate alternative water supply infrastructure. Operational savings result from lower utility costs since alternative water sources are often a lower-cost option.

The credit does not require that projects install physical connections to each flush fixture or make-up line. However, creating a plug-and-play system is highly recommended to limit future major renovations.

PATH 2. ALTERNATIVE WATER SOURCES

Option 2 rewards teams for implementing solutions to reduce reliance on potable water by using alternative water for indoor, outdoor, and/or process water systems.

The project must also meet all metering and commissioning requirements as outlined in WEp1: Water Metering and Reporting, EAp3: Fundamental Commissioning, and EAc5: Enhanced Commissioning (if pursued).
