In the reference guide there are a few different ways to determine recycled content value. When we are purchasing different materials/parts ie aluminum extrusions, aluminum panels, fasteners, insulated glass, sealants, to build a final product (WIndow System, Curtainwall) should we be using equation 1 referenced on page 372 and add each material up or use equation 3 on page 373? If we have to use equation 3 could someone please help expound on this? Is assembly cost the cost of all the parts and labor? This last questions ties into my questions in theMRc5 forum yesterday.

If you're purchasing the components separately then simply use Equation 1, the basic equation that takes the full value of post-consumer content and half the value of pre-consumer.If you're purchasing an assembled product, then you have to isolate the different components by weight and determine the recycled content of each. We expand on how to do this and provide an example in the Checklists tab above.
