No Water Used for Heat Rejection<br />
� Confirmation that no water is used for heat rejection.<br />
Water-Based Heat Rejection<br />
� Updated <strong>Building</strong> Water Calculator confirming the percentage of the projects<br />
cooling tower/district cooling water make-up requirements that can be served<br />
using the Exterior Water Allowance;<br />
� As-built composite utility schematic illustrating routing of recycled water mainline<br />
and laterals; and<br />
� Photographs of the installed cooling towers/district cooling plant, water recycling<br />
systems (where installed) and routing of recycled water mainline and laterals<br />
indicating their color code.<br />
No Water Used for Heat Rejection<br />
� Confirmation that no water is used for heat rejection.<br />
The projects cooling tower/district cooling water make-up requirements must be based<br />
on the proposed buildings cooling demand determined within RE-R1 Minimum Energy<br />
Performance / RE-1 Improved Energy Performance.<br />
The Exterior Water Allowance, EWA, that is available to serve the projects exterior<br />
water demand is determined as per the Calculations and Methodology section of PW-<br />
2.1: Exterior Water Use Reduction: Landscaping<br />
EWA must not be ‘double counted’ towards other uses such as irrigation and/or water<br />
features. The design team must decide upon the most appropriate use of the Exterior<br />
Water Allowance in order to balance their building wastewater volume with their<br />
exterior water demand. The overall water balance must be documented in the <strong>Building</strong><br />
Water Calculator.<br />
