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. For many years it was helpful - getting some materials to help folks see what they missed.  Last year they went to a new service... Read more

With the current push for improved window performance to meet energy codes and Passive House, room side low-e coatings can significantly improve window U-values. 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

Hello,

We are having a discussion / a bit of a debate in our office about the merits and sustainability of different roofing materials. Our current standard is to use a PVC membrane, which we all know is highly toxic. TPO is an obvious alternative that is less toxic, but it has some performance concerns and can often lead to leaking (not... Read more

Hello SCL, 

For those who missed our last call, I am posting the results from the 2023 Contractor's Commitment reporting cycle. Reporting at some of the higher tiers requires sharing case studies or information with SCL or the public. All the information that can be shared publicly (or that I received express permission to share) is now... Read more

Hi Everyone,

Who has worked on a SITES certification and can share the approximate hours involved for administering and completing documentation? A relative sense of the effort compared to LEED would also be helpful, similar to the thread about WELL on this same subject. 

Appreciate any insight. Thanks! -Hilary
