Hi all, has anyone come across a comprehensive (and recent) study looking at how long buildings actually last (beyond Stewart Brand)? I know of plenty that look at the benefits of reuse, but none that look at existing building stock and how much has been reused vs. demolished. 

As we start looking at embodied carbon metrics, I can't help... Read more

The question is: What are the arguments/ scenarios about the importance for homeowners to contract... Read more

Following up on one of our conversations on the vision vacuum and sustainability beyond certifications, I would like to help facilitate an offline conversation with anyone working within their firm to use the AIA COTE measures as a guiding framework in their firms/projects. Attached are my slides on my first pass at thinking about this at Page... Read more

Hey All,

I just received this from AIA MA. How fantastic would it to have a bunch of Green Gurus on the ICC Development Team! Is anyone on here already on it?

Auto-quiz used for CEUs for attendees of the 2023 SCL Fall Summit.

I have a client that is very interested in automated shades for a mid-rise multi-family housing project. Do you have any examples of projects that have attempted this? I assume it would involve occupancy sensors and/or an over-rideable default setting dependant on sun position and temperature. I also have an MEP Engineer team that is having a... Read more
