2. Submit the feedback survey using the link on the USGBC.org credit page; supply PDF of your survey/confirmation of completion with credit documentation

Credit Specific

New Construction, Retail – NC, Schools, Core & Shell and Healthcare Projects:

Provide the following:

1. A water analysis measuring as a minimum the five control parameters measured in ppm or mg/l.
2. Verification that sidestream filtration will be provided
3. Proof of a meter on both the make-up and discharge from the tower.
4. Location of conductivity meter.
5. Diagram showing meter locations, sand filter.
6. Drift eliminators specified on the tower achieving efficiencies of 0.2% or greater for counter flow or 0.5% or greater for cross flow systems.
7. Narrative describing the water treatment system and the number of cycles which the cooling tower can achieve without exceeding the control parameters.  The narrative should also include the predicted acceptable corrosion rates for each pipe material within the condenser water system.
