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...

We recently purchased two indoor air quality meters in the $200-$300 range and find that they never agree, not even close. I would like to find out what other people's experiences have been, and if they have tested affordable models that... Read more
