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

I have to admit that I wasn't particularly paying attention to LEED during Greenbuild, but anyone recall the "big announcement by USGBC" that LEED v4.1 is coming?

Article can be found @ Green Building Law Update by Stuart Kaplow and the title is "LEED v4.1 Announced by USGBC at Greenbuild."

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

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 know that there is a risk of starting a whole flurry of congrats through the forum, but this is a biggie, and deserves some recognition:

Congratulations Andrea and Melanie!! Huzzah!!

And a reminder--If you want to reach out to them privately, rather than through the forum, with your message, you can see anyone's email address by... 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...

Hi all,

We have a newly constructed, core/shell project having some hot water issues in the core restrooms.

There is a 0.35 Toto lav installed throughout. The hot water heaters are adjacent on each floor, located in the janitor closets. We did the math, and there could be a gallon of water standing and cooling in the pipe between... Read more

Hello - 

I am looking for the recording and the PDF/ slides that were shared 3/6 for the project process share-out/ 5 min presentations. It was super inspiring and I would like to refresh my memory of some of what was shared. Thank you!

There are a number of clear finish options available, from natural oils and low-toxicity products primarily used on residential woodwork through factory-applied finishes where specific aesthetics and/or added durability are required (such as those used on cabinetry or commercial architectural millwork). Many of these have very high VOC levels,... Read more

Hi all, has anyone come across a comprehensive (and recent) study looking at how long buildings actually last (beyond Stewart Brand)? I know of plenty that look at the benefits of reuse, but none that look at existing building stock and how much has been reused vs. demolished. 

As we start looking at embodied carbon metrics, I can't help... Read more

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

All Peer Networks were represented at this Boston Region Mini-Summit! With this first one in the books, BuildingGreen is hopeful for paving the way to future regional events across the... Read more

This article just came up in my news feed. I thought you’d all like to read it. I will point out that C&D-specific MRFs have told me that they are really good at single-stream C & D waste, as long as the drywall is pulled out.  Any drywall in a single-stream C & D dumpster ends up in the landfill. Drywall just breaks apart and gets... Read more

Seeking a dashboard system that will take energy use data from individual (college student) apartments to display in the lobby. Something where the display is both educational, easy to understand, and that could inspire a little friendly competition. Welcome any recommendations you have installed on projects or have seen that would be cool to... Read more
