Hi all,

We are designing a mass timber building and are closing in on selecting our mass timber supplier.  One supplier is offering FSC wood and the other is offering PEFC.  I don't know enough about PEFC to make a clear recommendation to the client about how it compares to FSC.  I understand that PEFC endorsed SFI, so that concerns me...

Hello, All,

Does anyone have experience with cove.tool (https://covetool.com/)?  Perhaps for those projects that may not get fully modeled, or as a tool to help set baselines?  It came across our radar recently, and I'm wondering if the subscription might be worth a try.

Thanks!

Hi all,

Has anyone been able to find alternatives to vinyl window film products? I can find solutions for wall coverings, but am not having much luck when it comes to window films. Any leads or insight would be really helpful!

Thank you!

Greetings to all of the sustainability leaders in the Green Commons!

Note: This is a message about politics, which we generally try to avoid in our safe space--but in this case it’s directly tied to climate action so I feel good about sharing it. Feel free to let me know or check in with the BuildingGreen folks if you have concerns or... Read more
