Can I gather EPDs for MEP equipment, and NOT be required to include the cost of those products in the calculations for Sourcing of Raw Materials?  The Reference Book is clear that "the denominator for cost-based credits (all Building Product Disclosure and Optimization credits) calculations must be the same".  The hangup for me was the use of "all" in that last sentence.  But if the strategy I am using for achieving BPDO EPDs and BPDO Material Ingredients are the options where cost is NOT required, then I should be able to achieve those credits without requiring me to also add the cost of them for BPDO Sourcing of Raw Material, right?
