I can see from the threads that there are at least a few Passive House advocates in this group - I'm wondering about the PHIUS training and certification. Can any who have done it offer an opinion? Is it valuable? Residentially focused? Would it apply to someone in a larger commercial practice? It's an investment of time and $, so I really want... Read more

Greetings to all of the sustainability leaders in the Green Commons!

Note: This is a message about politics, which we generally try to avoid in our safe space--but in this case it’s directly tied to climate action so I feel good about sharing it. Feel free to let me know or check in with the BuildingGreen folks if you have concerns or... Read more

Hi All, this is primarily directed at our Sustainable MEP folks, but please anyone with insight feel free to weigh in.

I am increasingly seeing designs and specifications asking for Passive House levels of airtightness as verified by blower door testing, but with traditional ventilation system designs. 

To me, Passive House US has... Read more

Dear SD Leaders: I'm writing to let you know about a great opportunity in campus-wide sustainability and design leadership. Washington University in St. Louis (my alma mater) is seeking a new University Architect and Assistant Vice Chancellor. WashU has a very strong legacy of sustainability leadership which has recently been reinforced with... Read more

Team,

See link above, a group of UK building services (MEP) engineers (like us) signed on above, committed to do life cycle carbon (including embodied MEP) in their work.

Are we behind?  Should we match them?  leap frog ahead of them?

Best,

Luke Leung

Though BuildingGreen has long supported the use of electric hand dryers as a more environmentally friendly hand drying option, the majority of evidence appears to support paper towels as a preferred method of controlling the spread of potential pathogens. 

And even the most efficient hand dryers contribute significant CO2 to the... Read more

I am diving back into Sefaira for the first time in a while, and the program still seems to be missing the ability to account for automatic daylight dimming in energy savings. Previously I had used an LPD reduction equivalent to emulate the savings automatic dimming would provide. Has anyone done a similar work-around? 

Hello SDLs,

I'm fairly new to the group, joined in November and I must confess to being a total wallflower here, having gone almost 6 months now without introducing myself. I am an Architect with Dyer Brown Associates in Boston, MA where I head up our firm's sustainability efforts, as well as devote a fair amount of time to '...

Does anyone know of studies that measure for any correlation between the prevalence of collaborative people in leadership positions with financial (or other) success for firms/organizations?

There have been well-publicized studies on how companies with women in leadership positions, and companies with more diversity, do better. (... Read more

What is the status of the roof insulation market regarding non-halogen containing polyiso boards? I know GAF and Atlas still have them. I thought JM had them as well, but seems to have taken them off the menu. Are there performance issues?

Hello SCL, 

I have a slightly different ask than my usual Contractor's Commitment announcements.

Our newest writer, Elizabeth Waters, and I are researching for a BG article about construction emissions and jobsite carbon for BuildingGreen.com

In particular, we are trying to research how much of a building’s lifetime carbon... Read more

I'm working with the AIA Minneapolis chapter on guidance for small firms related to how and when to energy model. A lot of small firms would like to sign the AIA 2030 Commitment (we had 100 in a room in 2022 in a session led by Nadav and Gwen Fuertes). But we have learned that a) they don't have a good way to energy model small commercial to... Read more

To piggyback off Nathan's introduction where he mentions construction waste management, who is doing anything innovative or different in managing construction waste?  Construction waste has not historically been a passion of mine, but now working in sustainability and construction, I feel like it has to be by default.  

We have a... Read more
