Hi - We have some projects within reasonable reach of ILFI's Zero Carbon Certification, which will require purchasing some off-site renewable energy. As a State Building Code Council member, I'm also eyeing the Zero Code which we will seriously consider in the next 12 months; this also requires a purchase of off-site renewable energy.

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!

Were we given any warning that LEED Online and USGBC.org would be down for a week?  

Hello SMEPers,

I’m hoping to crowd source some anecdotes for a guest lecture I’ll be giving at Yale’s architecture school. The topic is integrated design (especially between architects and engineers) and how it enables better sustainability outcomes.

John Boecker has this great story about how choosing a paint color with higher... 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

Hi All,

As of February 1, I’ll no longer be on this Forum as I don’t fit into any of the roles of SDL (yet) and I respect this space as a haven for those who do.  Helping to form this network with Nellie, Jim and Nadav has been a highlight of my career. Its truly exciting to see SDL networks finally expand to other practice areas.  I am... Read more

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

Many thanks,
