Hello, All!  We haven't run WBLCA on a project that may include electrochromic glazing before, and it's embodied carbon footprint is really high in comparison to a more traditional double or triple pane IGU (we thought it would be higher, but this is 3-4x higher).  The EPD we have from Sage Glass for their triple pane electrochromic lists a GWP...

Friends of EPIC –

Hey, everyone. As some of you might have heard, we’ve been working for a while with Autodesk to get c.scale (the data model behind EPIC) built into Forma – Autodesk’s AI-powered planning tool.

Has anyone found any options to recycle safety vests, or discovered an upcycling option for them?  We are about to replace all of our vests company-wide and will have thousands that we don't want in the waste stream and we don't want to be reused as safety vests.  Any thoughts or ideas would be great!

Thanks and I hope everyone is... Read more
