Hi, this is a somewhat niche/specific question - we are working on an all-electric school (middle and high school) that includes a chemistry lab. The lab was going to have portable sources for flame experiments, but there is concern that the portable sources would be unsafe for middle school students, so they are asking for a hard-pipe natural...

There are so many great contractor-related sessions at Greenbuild this year! I doubt I'm alone in trying to choose between sessions.  

Is there interest in debriefing with SCLers the week after (say Novemeber 9th at 2pm ET?). We could share the golden nuggets from the sessions we attended, saving everyone from wading through the session... Read more

Good morning SALs! Nicole's survey on restrooms inspired me to post a survey of my own.

I’ve been trying to stay useful lately. I've been posting new writing on the industry, much of it complimentary, over on Roberts’ Green Letter. (Yesterday I posted the mission statement, explained via brand-new-puppy pics.)

I have a 1-minute... Read more

Hi everyone,

As you may know the ICC has changed the way the IECC will be written in the future and most of us think that will reduce the stringency of the future energy codes that are the biggest lever in the fight against climate change within the buildings sector.

So one of the best pathways forward is via ASHRAE, which has a... Read more

Hello all,

Could any of you point me out to recent studies showing the health impacts of plastic piping vs. copper piping? 

We have a project where NIRON or Aquatherm are proposed as a VE item in lieu of copper.  I know there is some studies showing PEX and PVC piping health impacts, but I can't seem to find anything on these 2... Read more

Hi friends,

As you might have seen from my op ed last week on BuildingGreen.com, I’m convinced that just voting is not enough; we all need to do all we can to improve our chances of success in this election.

Hi Brilliant People: 

I'm hoping you can help me with a quick research question. A local colleague is trying to make the case to replace an existing old slate roof with slate vs. "slate look" asphalt shingles on a local public historic building. The bids are 6X higher for slate over the alternative 25-30 year solutions. They understand... Read more

I believe that Lindsay is in common cause with all of us here on this forum, and will provide meaningful built-environment contributions to COP.
Thanks for... Read more
