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!

At Greenbuild this year I'll be discussing how statistics can lie (in the context of green building claims).  I'm collecting examples of this to prepare.  If any of you know of examples, please send them to me!

Has anyone seen a comparison between IECC 2021 and previous versions of the energy code, including ASHRAE 2010? I'm curious how far ahead code buildings are relative to LEED v4.0, and how much the latest IECC raises the bar relative to the previous. I did a quick search for the LBNL and other studies that look at this, but didn't see anything... Read more

Hi all,

We're doing some tool-related soul searching at WRNS and some folks here have raised Cove.Tool as a potentially interesting addition to our library. I'm looking for any insight you all can provide. Cove has come up various times, but curious if there's been any change for the better/worse in the past few years.

Do you use... Read more
