It’s hard to believe COP28 is upon us. Kicking off tomorrow (11.30) and concluding 12.12, it’s sure to be a full few weeks of sharing, live streams, and interesting takes.

We’ve been excited to see a few Peer Network members represented as attendees in Architecture 2030’s (in-person and virtual) delegation.

We continue to encounter pushback on water-saving fixtures for concerns of ongoing performance. I'd love to have a dialog in this group because I find it hard to believe these challenges can't be... Read more

Hey, all. Two questions:

-How do we communicate to you LEED User content that needs to be pulled through to BIT-user pages? Are you all going to assess each BP page for potential articles/topics that will be linked?
