I would be interested in knowing if any LEEDUser out there has had a project successfully earn the PBT avoidance credit. What were the challenges and barriers? How knowledgeable were the reviewers? Given the energy with which manufacturers have long impeded the progress of such a credit, I can't see this credit ever getting successfully balloted. Also, you may have heard about the recent study showing the hefty weighting imbalance of energy efficiency strategies over human health protection: http://www.ehhi.org/reports/leed/LEED_report_0510.pdf
