Split Site Recycling

I recently had a schools (v2007) project where the main school building was seeking LEED certification but the athletic facility was not. Due to site constraints and logistics, it was impossible to set multiple rolloffs for each project. Using the cost of each project, we came up with a percentage for each project and multiplied the weights of each of the recycled and landfilled materials by this percentage to determine the LEED Site vs. non-LEED Site construction waste amounts. In our case, the majority of the waste was from the LEED Site where it seems like your situation is the opposite. Note: On two co-located LEED-NC v2.0 projects, this strategy was successful as well. There is a LEED-NC v2.2 CIR (Ruling dated 8/25/2008 – now listed as ID # 2316 in the LEED Interpretations database) that we referenced as well. It states, “If the project team can devise and document a method that accurately assigns the waste from the two separate projects before combining, then this would be an acceptable compliance path.” According to the Applicable Rating Systems and Tools chart in the LEED Interpretation, this ruling was not yet considered for LEED-NC v2009 – although it has been used for v2009 for Schools, CS, and CI. It might be worth further investigation.
