This USGBC administrative action serves to rescind the WEc2 ruling dated 6/28/02 and to clarify the casual mention of cooling towers and appliances on page 102 of the LEED-NC v2.1 Reference Guide. Only those fixtures regulated by the Energy Policy Act of 1992, the reference standard for WEc3, are to be included in WEc2 and WEc3. In accordance with precedent set by previous LEED-NC v2 certifications and in order to maintain consistency in the application of LEED-NC v2 across an increasingly broad range of building types, optimization of process water use is not eligible to receive credit under WEc2 and WEc3. Process water includes, but is not limited to, water use from cooling towers, dishwashers and clothes washers. Optimization of process water use is eligible for LEED credit under the Innovation in Design category. To date, no project has received credit towards LEED certification under WEc2 or WEc3 for optimization of process loads. Applicable Internationally.
