Dear all,

On a major renovation where the wall R-value/U-value needs to be brought up to energy code, specifically a mass wall situation, does anyone have insights on how the situation is best dealt with? On the project in question for me, the continuous insulation might have to be added to the inside surface of the mass wall and there... Read more

Hi SDLers! I hope early fall is finding you well.

There is a current opportunity to make a difference in the campaign to reduce use of toxic flame retardants.

Arlene Blum and the Green Science Policy Institute, whom many of you know, are currently organizing a campaign of support for the CA State Fire Marshal's proposal to allow... Read more

Hi SD Leaders: I'm writing to get your help identifying any experts or projects where all-electric HVAC solutions are being implemented in a large new build healthcare/patient care setting. The client has raised concerns about the reliability of an electric re-heat system and its ability to promptly respond to temperature controls. They also... Read more

Hi - some of you may have received an invite to the White House for a 3-hr session to continue the discussion on the Net Zero Emissions building that they released earlier this year. This discussion will be on embodied carbon. I have no idea who the invite went to. If I beg I may be able to go, but if there are plenty of other Architects that... Read more

Dear SD Leaders: The comment period closes January 31st on  NCA Volume II Climate Change Impacts, Risks, and Adaptation in the United States.

It's important to have the design communities perspective on these critical issues. I hope you can take a look and submit your comments before the deadline.

Details here: https://www.... Read more

Dear SDL: Thanks to all who have already given their support to the AIA Resolution on Urgent and Sustained Climate Action. We're into the final push of getting out the vote to pass the resolution next Wednesday, June 5th afternoon in Las Vegas. This requires 2/3s of the voting delegates to pass. So we're asking anyone who 1) is attending as a... Read more

Sharing the below message from Mike McMeekin, who some of you know, regarding his current initiative, the Engineering Change Lab USA Climate Change Noble Purpose Statement. (Also, here is a Link to today's LinkedIn Updates on this topic.)

Greetings, I am re-sending my email from last week primarily as a reminder regarding the sign-up... Read more

Hi All: I'm writing to see if I can get some recommendations/links to some great, free web tours of sustainable projects for use in an intro to sustainability class I'm teaching online this fall. Typically we tour some local buildings but that isn't an option this year. I'm hoping to find a few different ones for students to choose from. They... 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 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

Welcome to the quiz portion of What Makes a Product Green?.

Learning Objectives
Upon completing this course, participants will be able to:


1. List and describe at least three attributes that address each of the following categories: "efficient use of materials"; "responsible sourcing"; "energy and water... 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

Is anyone planning on attending the WELL Conference in Scottsdale in March?  I'm trying to figure out if it's worth attending or not?
