Hi Everyone, just as governors are regionally deciding how to reopen their economies, it's probably time we started thinking about what getting back to work looks like for us.  And, just as governors are leaning on each other for ideas and coordination, we can benefit from discussing strategies as a group.  To that end, I wanted to get your...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

Happy Friday, SDL!

We're running a Tally WBLCA for an environmental education center, which has a very small floor area but a fairly robust concrete/steel structure. Still, I was surprised to find an intensity of over 1,000 kgCO2/m2 for the building.

This is way higher than the general benchmarks I've found in the CLF's database,... Read more

Keith Hempel, Julie Hiromoto, and Billie Faircloth have been elevated to the AIA College of Fellows - I'm sure I'm missing others but congratulations! Can't wait to celebrate in person - I still rememer Lance Hosey in his tux and Beth Heider in a full ball gown at the AIA Fellows dinner in Chicago (the only one I ever attended. . .) 

I am looking for case studies/trying to identify buildings using concrete mixes with upwards of 30% replacement of cement by SCMs.  I've been in conversations with some structural engineers who are interested in lowering embodied carbon in upcoming projects, but would like to see examples of where this level of replacement has been successfully...

Phase one of the website will not include e-commerce (i.e. paid membership) but the BIT team wants to restrict access to some parts of the site, including the full Best Practices documents and the forum. This means we'll need a rudimentary paywall, directing users to register for full access.  Current registered users of BuildingGreen and... Read more

Following up something I mentioned at the summit - the EPA is hosting public comment webinars related to the IRA and construction. The first one seems particularly relevant, 3/2/23 from 2-3.30pm EST “Reducing Embodied GHG Emissions: Construction Materials Prioritization and Environmental Data Improvement”. Good opportunity to have our voices... Read more

Hi folks! Our AIA Seattle Committee on the Environment is hosting a series of decarbonization talks that might be of interest to this group. The next one is coming up next Thursday with the University of Washington.

Does anyone subscribe to Green Badger? Do you find it valuable?

Does anyone have experience pursing SITES certification on an essentially a zero-lot line project?

We are required to achieve silver certification, but the project scope/phasing recently changed and the entire site/parking area was eliminated and we no longer have a green roof. It still appears we can meet silver certification as so few... Read more

Hi all,

I'm sure many (most? all?) of us have heard the changes to LEEDv4's energy standard are coming. If this is news to you, info on the balloted measures that have passed is available online here: https://www.usgbc.org/articles/leed-v4-energy-update-approved-member-ballot.

For porcelain tile, BuildingGreen starts with the Green2 standard for sustainable tiling—ANSI A138.1 American National Standard Specifications for Sustainable Ceramic Tiles, Glass Tiles, and Tile Installation Materials. This is a multi-attribute... Read more
