Hi there SD Leaders,

We're running an LCA on one of our projects that's about to start construction that has had serious embodied carbon goals and I got a result that really surprised me.

Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item? 

Hi, all. We missed you at the standing check in today. We have a couple of questions for the BG team:

Does anyone have a spreadsheet or chart that compares the new Fitwel v2.1 with Fitwel v2.0 ?

I can't seem to find such a thing on the Fitwel website.

I am trying to determine which version-route to take on our "Workplace" project.
