Hello,

We are currently working on a project pursuing certification under LEED V4. Our construction period is expected to be complete in 2023 which is when we plan to submit our final construction phase LEED submittal for review. If we have an EPD that expires/is no longer valid before we submit for final review is that acceptable?

How does the USGBC evaluate compliance with the period of validity, is it based on when the design team reviews and approves the submittal or when the product is installed on site, or other?

Thanks, for any help you can offer.

James
