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!

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

Hi all,

I've tried a couple of different search terms for the forum but haven't been able to find any past conversations on electrochromic glazing yet (which makes me suspect I might be missing something...).

Hello, All,

Does anyone have experience with cove.tool (https://covetool.com/)?  Perhaps for those projects that may not get fully modeled, or as a tool to help set baselines?  It came across our radar recently, and I'm wondering if the subscription might be worth a try.

Thanks!

SDLers – For one of our projects we are working with local tribes to procure timber.

There appear to be two certification entities in our area: Northwest Natural Resource Group and Trout Mountain Forestry.  I’m... Read more
