Hello, 

We are becoming involved with the design/construction of a new k-12 school that is intersted in entertaining geothermal. Does anyone have payback studies on geothermal?

Thanks!

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!

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

Now that Ben has set up access restrictions, we have to decide what message to put on "paywall" screens. For example, on the Best Practices pages, the "Official language" tab is fully accessible, but if an anonymous user clicks on any of the other tabs they'll hit a login wall:

Hello SD Leaders!

I recently joined and looking forward to all the amazing dialog. I was told that for membership to be official, I must reveal my unsustainable secret.
