The LEED Form states that the project has reduced potable water use by 23%. However, to demonstrate compliance, the following must be addressed.

TECHNICAL ADVICE

1. If the project team is attempting WEc3 for the Design Final review phase, provide revised calculations within WEp1: Water Use Reduction and resubmit this credit demonstrating that the project has reduced potable water use by at least 30%. Please provide documentation, such as copies of Change Orders, indicating the plumbing fixture revisions. Additionally, provide a revised plumbing fixture schedule from the project's construction documents, outlining detailed information for each flush and flow fixture specified (including fixture manufacturer, model number and flow rate) verifying that these revised fixtures are part of the construction contract.
