Hi folks,

I hope you've seen the plug to sign onto the letter that's generated a flurry of messages on Green Gurus--I also emailed it out directly to everyone. We've got lots of architects on board, and a handful of engineers, but I think we just have one contractor so far (Thanks Theresa!)--it would be really awesome to have more.

We are embarking on our first CLT projects (our at least we hope that they go that way). Would anyone with experience be willing to share some thoughts from the architect's perspective on things to consider, lessons learned, etc?

I am excited to announce that BuildingTransparency.org just launched downloadable specs and associated guidance that a couple of us have been working on for a few months.  Here is the EC3 announement:

There is a ton of stuff being posted about this, so this is definitely an area where it's nice to have had someone going through it and selecting the best. Thanks for doing that, Jen!
