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

This may seem a bit in the weeds, but I have typically paid extra at Greenbuild for the access to the materials after the conference - we use that to develop presentations back to the teams who are not able to attend.

We're curious how others are defining "habitable" and what systems assumptions... Read more

However, back in 2018 Payette did this excellent study that showed that while room side low-e coatings improved window U-value and increased the interior radiant temperature, the... Read more
