I've been asked to author an article on urban heat mitigation, and I wanted to include a plug for the above pilot credit, which I think is a really powerful new addition to LEED. Beyond introducing the "intent" and "credit requirements", I was also hoping to do (2) things within the article:

This article just came up in my news feed. I thought you’d all like to read it. I will point out that C&D-specific MRFs have told me that they are really good at single-stream C & D waste, as long as the drywall is pulled out.  Any drywall in a single-stream C & D dumpster ends up in the landfill.

Thanks and I hope everyone is... Read more
