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...

Hello Green Gurus,

Now is a pivotal moment. Net Zero Stretch Code legislation has been proposed in the Massachusetts House and Senate, and draft code language is currently being developed by the Board of Building Regulations and Standards (BBRS). The Net Zero Stretch Code is currently the greatest single opportunity to support reduced...

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

I am at a smallish firm (20 people) in Boston helping to reform our processes to enable even those that are not steeped in sustainability at a daily level to be comfortable looking for opporutunities... 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.

Hi Carbon Working Group,

It’s been a while since our last online meeting on 3/31 –- admittedly, a bit too long -- so I wanted to share some updates.  You might have seen Candice Pearson’s 5/13 post about the structure of the Contractor’s Commitment and how it’s evolving into a set of guidelines available not only to our SCL Group but to...

Hello Gurus,

I have a client (bldg owner) who has asked me to recommend a list of firms who have the internalized resilient design in their practice.

They are *not* asking for resiliency consultants right now, but for firms that they might hire for "regular" capital projects, but since resiliency is high on their priorities, they... 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
