Hi! Please see this query from our Products Editor, Brent Ehrlich. Feel free to reply here on the forum with any leads or insights. AND, if you will to go "on the record" for this article, please contact Brent directly to set up a phone or email interview. (He's on a tight deadline with this.) Thank you!

I am looking for some feedback on... Read more

I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

Building materials emit massive amounts of carbon long before the lights go on.

In this course, BuildingGreen takes an analytical look at the greenhouse gases that are emitted in the process of constructing our buildings in the first place—the embodied carbon. The report focuses on how architects and designers, working with other key... Read more

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.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

I understand the AIA 2030 team is hoping for as many firms (and projects) to submit some form of LCA data in the new DDx website this week, in order to learn how the industry is tracking embodied carbon.  We have four projects that dabbled with Tally last year, which we'd like to report this week.

Has anyone run into a hurdle where you... Read more

Dear Green Gurus: I'm so sorry to have missed seeing many of you at AIA last week. I heard the BG and COTE events were the highlights of the week! Congrats.

I'm sure by now you've heard of the dreadful Supreme Court decision about the EPA. I thought I'd share a helpful, if not sobering, perspective in an Op-Ed today in the Washington... Read more

I really appreciated our day on Tuesday--seems that we had a great inaugural Summit, and covered a lot of important ground. 

Here are the raw notes (flip-chart pages) from the day. Some of us came away with Action Items--see the list on the last page. 

Five-minute presentation decks and a more polished report to follow shortly. We... Read more

Great meeting everyone and very excited to work with you all.  Reminder about Tuesday night's homework assignment to support Sachin's efforts to upgrade the quality of our AE pipeline:  tell us why you got into this business.

While I was an undergraduate engineering physics major*, I had a partime job at a farm implement manufacturing... Read more

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

A brief non-technical rant about OneClick LCA - from someone who is not actually USING the tool, but lobbying for its access.  Wondering if you all have better intel, or if it is just me.

We are working on a number of projects for which te teams are using OneClick LCA - for some cases it has a better international data set than others. ... Read more

Hello, All!  We haven't run WBLCA on a project that may include electrochromic glazing before, and it's embodied carbon footprint is really high in comparison to a more traditional double or triple pane IGU (we thought it would be higher, but this is 3-4x higher).  The EPD we have from Sage Glass for their triple pane electrochromic lists a GWP...
