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...

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

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

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Thanks to SERA especially David, Kira and Clark for an inspirational conversation with Paul Hawken about his latest book. I know I needed a positive perspective! Then I found this great "Regeneration Anthem" song and had to share.

Happy Fall to all.

Hi folks,

No details have been sorted out yet, but I wanted everyone to have a heads-up that the SCL Steering Group is proposing that we graduate to a full, stand-alone SCL Summit in 2020. (Until now we’ve been squeezing our Summit into the day before Greenbuild, which is good in some ways, but problematic in others—and limits our time... Read more

Have any of you relied on Green Badger for LEED documentation on projects?

I am familiar with the tool and know Tommy from my time in Atlanta, but have not used it on a construction project.

Have you found value? Thoughts?

Either way, they publish a pretty nifty "LEED v4 Construction Tool Kit" that may be useful for your... Read more

Following up on one of our conversations on the vision vacuum and sustainability beyond certifications, I would like to help facilitate an offline conversation with anyone working within their firm to use the AIA COTE measures as a guiding framework in their firms/projects. Attached are my slides on my first pass at thinking about this at Page... Read more

Hi SD Leaders,

As you may be aware, this past April a group of manufacturers calling themselves the Living Product 50 responded to the letters that many of us sent about five years ago advocating for transparency in their product ingredients.  A copy of that letter can be reviewed about midway through the page at this link:  https://...

Hey all - sorry I won't be able to join our call today. I had a client request an emergency meeting today (boo) because corporate mandated that they eliminate fossil fuel use from all their buildings (yay!) by 2025 and they've got a project underway that needs to pivot quickly. 

Had I been able to join, I wanted to share this in case... Read more

hi all! I'm almost at the finish line with this year's 2030 reporting...whew. I'm running into an issue that I wanted to throw out to this group, regarding the zero tool and national average baselines. Hoping some of y'all who manage your firm's 2030 data, or are just more familiar with CBECS and related data, have some insight / experience to... Read more

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more

Hello,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

Hello SDL!

Has anyone set "Ecosystem Benefits/Service" targets for an individual project or for all their projects? I was previously against the idea of even measuring ecosystem benefits but I've had my mind changed in recent months!

Currently we want to set a target for every project to: "Improve ecosystem benefits on every site... Read more
