Hypothetical situations:
LEED EBOM for a furniture manufacturer:
Paper towels for the bathrooms are "ongoing consumables".
Tack cloths (similar to paper towels) are for used for wiping down furniture pieces about to be coated with finish. They are part of the manufacturing process, not the building operation per se. Are they "ongoing consumables"? What about the wood purchased to make the furniture?
LEED EBOM for a cleaning chemical manufacturing company.
They have a lab where they prototype new products. Are the raw materials for the prototypes to be counted in calculating % of green materials? These materials are regularly used (to make products) and replaced and are not necessarily expensive, but they are not a part of the operation of the building itself.
