All,

I'm looking for a quick methodology to estimate GHG emissions from refrigerants on a per SF basis. Are there any benchmark studies or quick calculators similar to the embodied carbon study? https://carbonleadershipforum.org/embodied-carbon-benchmark-study-1/

We have a project that is looking for plaster/stucco/textured wall products that are sustainable, or “more sustainable.”

I know these products exist, but I haven’t had to spec or work with any, so I’m reaching out.

The project is in MA, so I'm also soliciting recommendations for products and/or companies who are experienced using... 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://...

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

Hi all,

HOK has ~75 WELL APs whose credentials will expire in 6-12 months, so we're starting to look into a more robust CMP program.  Do you have great sources of health + wellbeing education, particularly WELL-specific CEUs, that you would recommend (emphasis on free or very low cost)?  We are currently using GBES, BuildingGreen, and...

I've been seeing Armstrong's DC flexzone ceiling system at Greenbuild for many years. I'm working on a net zero project with LED lights and solar panels. In theory, the transmission losses in going from DC power from panels to AC for the building to DC for the lights would be eliminated. But does anyone actually have experience using this...
