Our fledgling group had an organizing call last Tuesday, March 17th. Of course, it was a great conversation - the group is full of amazing people! The focus of our conversation was the goals and actions that should drive this group forward. I have a few ideas. Please share your own in this thread!

I start from the belief that we see our... Read more

Hi folks,

There was a lot of interest on the call yesterday in the article that Kim showed from a host of leading IAQ experts. I was not able to find a legal way to get a copy that we can share, so if you want it I think it would be appropriate to either pay the $30 for the article (one-day access ??) or $79 for a one-year AAAS...

I'm teaching a LEED GA study group and was rambling on the differences between CIR and precident-setting LEED Interpretation (that gets posted in the addenda library and all). Then I went onto LEED Online and was showing how those are submitted... but can't actually figure out how a LEED Interpretation would be submitted. Has anyone done this... Read more

Which sections will be freely visible, and which will be visible only to registered users? Here's what I recall from our earlier... Read more

I looked through the forums and was surprised to see that from what I can tell this 2018 article from Yale I'm going to share here has not been discussed previously.  It basically says that FSC is not trustworthy, ineffective, and greenwashed, as critiqued by the likes of Greenpeace and others.

I would like to hear from someone in the... Read more

Hello, folks! We recently had contact with Northeastern University about sand. I know it sounds ... dry. But sand shortages are a serious issue globally and are leading to criminal activity everywhere and even "sand mafias" in poorer nations without resources to enforce mining laws.

The ask from Northeastern is that BuildingGreen amplify... Read more

Buildings aren’t garbage. But you wouldn’t know it by examining the way the AEC industry works. 

We typically design buildings for a single, limited purpose. We build them partly out of plastics that can’t be readily recycled. We choose diverse materials... Read more
