A client had a waste audit done for MRc6 in weight (36% landfill diversion) and we analyzed MRc7 in volume (55% landfill diversion). The volume analysis included private tenant paper shredding, which gave the project an advantage. Now our LEED reviewer is questioning how the audit was so much lower. In addition to explaining the paper shredding inclusion in our response, we are clarifying that they used different units of measurement, so they can't be compared fairly. But now we're questioning if there is a requirement that both credits use the same units of measurement? We're not finding clarification anywhere. Advice?
