Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

This month on our Sustainable MEP Leaders call we were asked what resources would be suggested for advancing integrative design.

Two books immediately came to mind for me:

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Hello all,

We are having a mini office debate on fiberglass vs aluminum windows for use in schools (k-12) in Massachusetts. In the past we have always used aluminum windows on our schools, for durability. However, their performance is not as great as other products that are up and coming on the market. There is some hesitation to switch... Read more

We haven't... Read more
