The construction sector’s take-make-waste approach to materials needs an overhaul. Materials and construction account for an estimated 11% of global greenhouse gas emissions annually.

We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Hello all!

I'm new to the group, and so excited to be here. Two part question here (as we think about processes and new year goals).

I am at a smallish firm (20 people) in Boston helping to reform our processes to enable even those that are not steeped in sustainability at a daily level to be comfortable looking for opporutunities... Read more

I'm sure if I hop in the way back machine I could look in the forums and find old threads on LEED GA and LEED AP study resources, but I also know that material comes in and out of date. Has anyone found a good, current solution for firmwide LEED study materials?

We're off and running!

Hi Carbon Working Group,

It’s been a while since our last online meeting on 3/31 –- admittedly, a bit too long -- so I wanted to share some updates.  You might have seen Candice Pearson’s 5/13 post about the structure of the Contractor’s Commitment and how it’s evolving into a set of guidelines available not only to our SCL Group but to...
