What is the status of the roof insulation market regarding non-halogen containing polyiso boards? I know GAF and Atlas still have them. I thought JM had them as well, but seems to have taken them off the menu. Are there performance issues?

Hello SCL, 

I have a slightly different ask than my usual Contractor's Commitment announcements.

Our newest writer, Elizabeth Waters, and I are researching for a BG article about construction emissions and jobsite carbon for BuildingGreen.com

In particular, we are trying to research how much of a building’s lifetime carbon... Read more

As part of my goal to increase staff education frequency, I'd like to introduce some training and certificate programs into the mix. I wonder what programs others have recommended to staff? Not just attending conferences (low accountability) or CEUs, but things like the Parsons Healthy Materials Certificate, or Phius/PHN passive house... Read more

Hi folks,

As you've no doubt heard from us by now (several times), in lieu of Summer Summits this year we're offering a combination of events this fall. Our series kicked off last week with a great Regional Mini-Summit in Boston. Regional events like this were in our plans before COVID blew everything up, so this one was a long-time... Read more

Hi - some of you may have received an invite to the White House for a 3-hr session to continue the discussion on the Net Zero Emissions building that they released earlier this year. This discussion will be on embodied carbon. I have no idea who the invite went to. If I beg I may be able to go, but if there are plenty of other Architects that... Read more

Can anyone point me to a (dream?) resource listing effective R-values of various wall assemblies?  We are trying to find a cost-effective R-40 wall assembly for a one and two story public middle school targeting net zero energy in Oregon.  Referencing Seonhee's "thermal bridging" thread in late April, I used Therm's native drawing feature, but...

Hello all, excuse the blast and the short timeline -- while not explicity sustainability-related, this is a great way to connect with the future of the profession, and can be a great opportunity for SDL firms on the west coast (a number of SDL firms already participate), specifically in Tacoma, Olympia, San Francisco, Sacramento, or San Diego....

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.
