NGBS Green +ZERO WATER
LEARN HOW TO earn the +ZERO WATER certification
NGBS Green+ certification provides a streamlined, supplementary, third-party recognition for NGBS Green Certified homes based on their exceptional performance in one (or more) of six categories of green practices, including ZERO WATER. A zero water home/building is designed to offer reduced environmental impact and greater independence to residents. With a zero water design, water use is minimized; water utility bills are eliminated. Designing and constructing for a zero water home involves careful design with efficient structural plumbing design, efficient fixtures, and landscape and other outdoor features that require limited water. In addition, storage tanks and treatment devices are installed to facilitate the capture and use of rainwater, greywater, and blackwater. Homes that demonstrate that they were constructed to be zero water can earn the NGBS +ZERO WATER certification.
Compliance Criteria
Required to earn the +ZERO WATER certification:
- Projects must comply with the Water Efficiency chapter via the Performance Path (Water Rating Index).
- A home or building must achieve a Water Rating Index (WRI) score of “0.” This is evaluated by a specially-trained NGBS Green Verifier using the Water Rating Index (WRI) Calculator.
Only New Construction projects are eligible to earn the NGBS Green+ ZERO WATER badge.
