Hi folks,

I hope you've seen the plug to sign onto the letter that's generated a flurry of messages on Green Gurus--I also emailed it out directly to everyone.

My firm recieved an invitation to this event in March. Wondering if anyone has any insight on Metropolis Mag events or if anyone here plans to attend. Looking forward to connecting! 

Hi All, this is primarily directed at our Sustainable MEP folks, but please anyone with insight feel free to weigh in.

Hello, All!  We haven't run WBLCA on a project that may include electrochromic glazing before, and it's embodied carbon footprint is really high in comparison to a more traditional double or triple pane IGU (we thought it would be higher, but this is 3-4x higher).  The EPD we have from Sage Glass for their triple pane electrochromic lists a GWP...
