ENHANCED WATER EFFICIENCY

WEc2

1–8 points

INTENT

To reduce potable water consumption and the associated energy consumption and carbon emissions required to treat and distribute water and to reward the use of alternative water sources that preserve potable water resources.

REQUIREMENTS

Achievement pathways	Points
Commercial Interiors	1–8
Option 1. Whole-Project Water Use	1–8
OR
Option 2. Fixture and Fittings — Calculated Reduction	1–6
AND/OR
Option 3. Appliance and Process Water	1–2

Implement a combination of the strategies below for a maximum of 8 points. Projects may either attempt Option 1 or any combination of Options 2 or 3 below.

Option 1. Whole-Project Water Use (1–8 points)

To pursue this pathway, project teams must develop a water use baseline and create a proposed use model. Points are achieved based on reductions from the baseline in Table 1.
