Figured I'd throw out this topic to the hive mind!

We are working on a project in the Midwest that involves taking down and replacing an 100-ish-year-old brick building. We are hoping to find a way to salvage and reuse some of this brick in new construction. I'd love to do an LCA comparison showing the benefits of salvaging the brick vs... Read more

Hi friends,

We recently tracked our water consumption on site during the structural demolition of some existing reinforced concrete buildings.  The new OSHA silica regulations required us to keep dust to virtually zero, so we had a bunch of mist cannons and water hoses pumping water around the clock.  We consumed ~855,000 gallons in a...

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all.

Hi folks,

Oregon’s ZERO Coalition is looking for responses to the question below on local policy for electrification, and I thought tapping this group would be helpful.

Are you aware of any local governments outside of Oregon that are promoting or enforcing electrification?

Returning to work: for many, it’s unthinkable without some kind of reassurance that leadership and the facilities team have taken all possible precautions. Lots of organizations are weighing in on what we should pay attention to, but how do we know if it’s working?

The free Re-entry program from Arc is a tracking and measurement... Read more

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:
