One of my project includes an indoor swimming pool at a Rehabilition Center. I do not know of any way to apply the water savings gained by the use of a more water efficient filter in lieu of the traditional sand filter to any LEED v3 credits The more efficient filter uses much less chlorine and exponentially less water (200 gallons per every other month vs. 2000 gallons every week), BUT the tradtional sand filter is significantly less expensive and has simpler maintenance. The pool consultant had luck with receiving innovation and design credits in previous versions for the use of the "innovative" water efficient filter, but no longer in Version 3. So because it appears there is no LEED incentive to use the more environmentally senstive system - coupled with that it is more expensive - we are facing a difficult sell to the pool consultant and owner. Any suggestions? Am I missing something?
