Championing the
Changemakers

Hi All,

I'm teaching a class this semester at CU Boulder on Zero Carbon Buildings and Cities (a new class that I'm making up as I go). The hardest part, I'm finding, is locating some good materials that cover the basics of energy efficiency for non-building engineers or designers (we are energy and sustainability generalists in this...

I was recently asked if there is a way to quantify financially what one MT eCO2 might be worth in the context of a building owner reducing their own carbon emissions.  How do you put a dollar value on those reductions?  Does anyone have experience with that or can you point me to the correct resource to answer this question?

Remember 2013? LEED version 4 had just been released to the public. Hardly anyone was using it, though—not only because they didn’t have to, but also because there just wasn’t a pathway to achieve many of the new credits in the rating systems. Especially the product-related credits in the Materials & Resources category, along with the Low-... Read more

Hi all,

We have an institutional client who has tired of LEED and is instead putting forth EarthCraft Light Commerical as a replacement certification (they like the performance verification & lower cost that ECLC provides).  Has anyone used ECLC? It seemed an odd choice but wanted to hear from others on their experiences. The... Read more
