Hi all! I'm very excited to report that we have interest from a developer client in tracking embodied carbon through construction. We have issued construction documents and the construction managment team is begining the process to establish the GMP.

We're looking to use EC3, and/ or ZGF's LCA analysis tool for concrete to look at how we... Read more

Greetings to the Green Commons!

Those of you who attended Greenbuild may remember that during one of the keynotes, Ali Zaidi - White House National Climate Advisor, announced that the White House was developing a definition for "Zero Emissions Buildings" (here’s a [LINK] to a related Washington Post article). The draft language for the... Read more

Hi all,

I am working on a Div 01 sustainability spec section for our firm to include by default on all projects. I've been finding a lot of great sample language out there for embodied carbon measures and material transparency (huge thanks to anyone here who had a part in developing those resources). 

One thing I'd like to include... Read more

We think fresh water supplies are endless, but this idealistic vision is clouded by the smoke of countless forest fires in the U.S. West and elsewhere. Instead of endless bounty, climate change is bringing us catastrophic droughts and flooding that now dominate the headlines and threaten entire regions.

This report covers innovative... Read more

I'm passing on an alarming (and truly Orwellian!) message from the AIA that some may have received:

The AIA is aware (and has been actively addressing) that there is a draft executive order circulating for consideration by White House officials that would officially designate “classical” architecture as the preferred style for the... Read more

Hi all,

We have an institutional client who has tired of LEED and is instead putting forth EarthCraft Light Commerical as a replacement certification (they like the performance verification & lower cost that ECLC provides).  Has anyone used ECLC? It seemed an odd choice but wanted to hear from others on their experiences. The... Read more

I'm pleased to announce that the AIA Board of Directors has unanimously adopted the A&D Materials Pledge as the AIA Materials Pledge!!!!! The support of so many of you was a key factor in making it so easy for the AIA Board to adopt The Pledge. The Materials Pledge now has 90 signatory firms, including many of yours. Thank you all.  Now,... Read more

Hi all - at the suggestion of Nadav and some of the Sustainable MEP Leaders, I'm reposting a thread I started a couple days ago in the SMEP forum.

In response to increasingly aggressive (and effective) targeting of building owners (particularly schools), a group of researchers have put their support behind a letter warning against the... Read more

Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...

Durability is the first priority for roofing membranes since interior repairs and replacement waste material, time, and money.

The Getting to Zero Forum is happening next week in Minneapolis, Minnesota (my home state!). Anyone else from this group planning to attend in person? I'm especially curious as the Forum comes so quickly on the heals of the Living Future Conference.

As a proud Minnesotan, I have a hard time imagining how anyone could ignore an... Read more

Hi SD Leaders, my firm wants to make a case for conducting LCAs on all major projects. I'm curious what your experience is - how long does it take to conduct an LCA (for the analyst's effort and other project team members who attend meetings about the LCA and use its results), and the type of LCA software you're using. 

I feel sure you'... Read more

Building Green is the longest continuous running green building publication in the world. Its originator, West River Communications, was founded in 1985 as “a company that would translate technical information on energy efficiency and other environmental topics for the public and building...
