Hi All,

I want to share this report, released today, that I and some other folks on Green Gurus have been working on.  The report dispels the myth that Zero Energy Buildings cost more (specifically in Massachusetts) and it goes further, making the case that Zero Energy Buildings are actually great investments.  Take a look, tell us what...

Hi Green Commons,

It’s been eerily quiet here since Tuesday night. I’ve been quiet mostly because I just didn’t know what to say. The election results are certainly a blow to pretty much everything we’ve been working for. There is so much we don’t know about things might play out, but I’m feeling a range of emotions ranging from... Read more

Fellow Sages,

I was at an interesting lecture last night. Phil Bernstein (formerly of Autodesk, now at Yale) was speaking (in Lawrence, Kansas, at the U of Kansas) about AI and design/AEC ... you may know that he authored the 2022 book, Machine Learning, about AI and the AEC field. 

Phil has a very interesting posture about AI... Read more

How much does every designer need to know? How to support that basic literacy?

Guiding Questions:

In trying to help a client write a case study on avoided carbon by using slag and flyash, I am having trouble finding a one for one equivalency that can be verified.

I have found for one pound of flyash, one pound of carbon is saved - but I can't verify that.

Appreciate the feedback!
