LEED Interpretation ID# 2535 ruled that, under LEED 2009, FSC-certified bamboo could be counted under both MRc6 (Rapidly Renewable Materials) and MRc7 (FSC Certified Wood). Does this recognition extend to the recognition for FSC-certified wood under Option 2 of this LEEDv4 credit? Or is it the case that, for bamboo to qualify, it needs to meet the requirements for Bio-based materials?
