alt. process water treatment (similar to dolphin system)

Lisa, what are your thoughts on the reviewer's comments? While I think your proposal for the ID credit has potential, it looks like their requests for clarification, particularly item #2, are fairly reasonable.

Lisa, I would also suggest taking a look at LEED-EBOM WEc4: Cooling Tower Water Management and see if you can design the ID credit around that credit language. Incorporating a training program for the facility staff is one way to address the "comprehensive strategy" issue.

Lisa - I came across your post because we would like to also pursue an ID point for using chemical -free water treatment for our cooling tower. We've been told by the manufacturer that project teams have achieved on other projects that used their product. Have you looked at the ID/CIR catalog published in 2008? You can view/download here: http://www.usgbc.org/ShowFile.aspx?DocumentID=3569 It has some guidance. I had been told to provide plenty of calculations showing water use reduction (due to reducing blowdown), and a narrative explaining advantages of not having the chemicals onsite.
