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:

I am wondering how architectural firms plan to close the gap to zero in the next few years. 

Owner's dictate outcomes and the typical owner is not committed to zero - even when sustainability is a focus of the project. 

We can present solar-ready designs, all electric buildings, geothermal, etc. but there is still quite a gap to... Read more
