Hey everyone, 

With the coming In-Use Off-Road Diesel-Fueled Fleets Regulation | California Air Resources Board we have been doing some research on availability of R-99 fuel prior to the January 1 start date. One thing we aren't finding in the research is an estimate of cost impacts. Has anyone started rolling out R-99 on their sites yet... Read more

Hello Everyone,

I'm looking for projects in Chicago that are exemplary in at least one of the following topics: Biophilia, Sustainability, Resilience, or Well-being. I know there is overlap in these topics but we're doing an internal design exercise and are looking at how these different ideas relate and are articulated in buildings. We'... Read more

As part of the Philadelphia AIA COTE, we have been proposing implementing sustainability in some fashion into the design awards with our chapter's design committee.  I know that many of you have been down this road before, and wanted to get your feedback at a high level about what your local COTE is doing.  Anyone who's interested, can you...

Hi there colleagues!

Out of curiosity, do you plan on attending Greenbuild in person in San Diego in September? My staff asked me if we were going and my answer is partially contingent on the extent to which attending would mean getting to see some of our favorite people (read: all of you).
