Links to some resources to address this issue are below. Feel free to ask me and/or Stefan Knust about it. We would be more than happy... Read more

What got me thinking was this article from Prof. Joe Allen at Harvard about... Read more

We have all these resources out here in the ether but it’s so hard to pull them into one spot! I was asked, last minute to join a client call today to help convince both the client (affordable housing developer) and the mechanical engineers to "stick with" a commitment to 100% electric design that was publicly stated when the competition was...

Hi all,

I'm curious how various firms are approaching their own office projects, re green building certifications. I'm especially interested in medium-large firms that have multiple offices, but policies and processes from small firms may still be instructive.

Do you have a firm-wide policy or is it a case-by-case thing? Has... Read more
