EPDs covering several product series

Jean, if they are truly three different products by the definition in the ref guide, I believe they would still count as three products from one manufacturer. The EPD should have different sections detailing how the impacts change from product to product. But check against that definition of a "product" in the ref guide before submitting.

Jean, thank you for posting this question! We have a very similar question and looking for some guidance on assemblies and/or products that are made up of multiple materials. Additional examples: Curtain wall systems, windows, skylights, etc. Hypothetically, if there was an industry-wide EPD for Aluminum and Glass, would we be able to claim 2 Industry-Wide EPDs for a window? Or does the Window Industry need to have their own Industry-wide EPD? Or do windows only qualify for Product-specific EPDs? Thank you!

Another scenario I am looking at is for concrete. While each mix design is intended for a specific purpose (walls, footings, grade beam, slab, etc) the overall purpose could be defined as the same - building construction/support/strength material. May we use the industry level EPD which was produced by NRMCA and have it count for each separate mix? My initial thought is yes, but I would like to hear your ideas as well.

Given the liberal intent of the credit language here, I think you could count each mix, and similarly each aluminum product.This should be tested with real projects and contacting GBCI to confirm, and please report back here as you go!

Thanks Tristan. We will add to our inquiry list on a specific project for December. Will report back next month!

Hello Megan have you received a response for this question? Also a related question for everyone, is there a minimum required amount (volume/area/cost) of product that must be used to contribute as one product for option 1? What is stopping someone form swatching 20 different paint products onto a wall inside of a closet to achieve the credit?
