Sustainable Purchasing clarification

Good question, and the calculations get a little sticky when only components of a product comply. The LEED for Operations & Maintenance Reference Guide does not address this as directly as LEED for New Construction Reference Guide, which states that the recycled content (or rapidly renewable, regional, etc.) value of a material assembly is determined by weight. The recycled fraction of the assembly is then multiplied by the cost of the assembly to determine the recycled content value of the entire product. For example, if a $10 product weights 10 pounds, 5 pounds each of plastic and wood, and the plastic portion contains 50% post-consumer recycled content, the overall recycled content value is $2.50 (the recycled fraction is 50% of 50% = 25%, multiplied by $10 = $2.50).

Yes, but is this the case for EBOM? The credit does not seem to suggest this as it does in LEED NC.
