Has anyone here had success in comparing life cycle impacts for different window system options? We have been trying to compare different options but have only been able to source one expired EPD for an actual window (frame + glazing). Is the typical approach to separately compare glass and framing options? Are we missing something or is there... Read more

I was recently asked about potentially specifying concrete with wood nanoparticles and concrete with biochar as a way to further lower the embodied carbon and to increase concrete strength.  These approaches are something I know nothing about, and wondering if anyone in this group has any experience and/or observations that might be relevant to...

Hey all,

Question for those of you who do in-house daylight analysis about modeling translucent glazing.
