Electrochromic glazing holds the promise of less glare and better energy efficiency with fewer moving parts. The reality is much more complicated and includes information you won’t... Read more

I'm putting together information on natural gas bans (or put another way, all electric buildings) for an advocacy effort and looking for some experts. Anyone have thoughts on banning natural gas and other fossil fuels on residential projects? Specifically what are the considerations/challenges/opportunities at each scale (single family, low...

Greetings to the Green Commons!

Those of you who attended Greenbuild may remember that during one of the keynotes, Ali Zaidi - White House National Climate Advisor, announced that the White House was developing a definition for "Zero Emissions Buildings" (here’s a [LINK] to a related Washington Post article). The draft language for the... Read more

Hi all! I'm very excited to report that we have interest from a developer client in tracking embodied carbon through construction. We have issued construction documents and the construction managment team is begining the process to establish the GMP.

We're looking to use EC3, and/ or ZGF's LCA analysis tool for concrete to look at how we... Read more

Hi all,

I am working on a Div 01 sustainability spec section for our firm to include by default on all projects. I've been finding a lot of great sample language out there for embodied carbon measures and material transparency (huge thanks to anyone here who had a part in developing those resources). 

One thing I'd like to include... Read more

Anyone using the USG EcoSmart drywall? I'm writing a short product review and am looking for some quick feedback. I'm particularly curious about reduced greenhouse gas emissions and overall cost. Thanks! Brent

Hi GGs,

We are looking to do a renovation of a very leaky old office space, and we want to get a good snapshot of air quality and effective envelope R values both before and after.

Does anyone have experience with:

1. installing heat flux sensors on windows and walls

2. deploying IAQ measurement devices that can log... Read more

Thought I'd share this interesting research about something I hadn't considered as another pandemic impact - the use of video in Zoom etc calls vs. audio only. Maybe an excuse to keep your camera off some of the time?

I’m curious what people think.

Building Green is the longest continuous running green building publication in the world. Its originator, West River Communications, was founded in 1985 as “a company that would translate technical information on energy efficiency and other environmental topics for the public and building...

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...

Show & Tell Breakout. Presentations:

Has anyone been involved with GBC Italia's Historic Building protocol? They are requesting pilot projects and I'm wondering if anyone has experience using or developing this framework. 

See attached checklist and form. Their website is pretty challenging to use. But so is USGBC...

Thanks!

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

Hey all,

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

We use ClimateStudio for our modeling. It has plenty of material options for clear glazing but nothing for translucent glazing, and we are trying to understand the impacts of a translucent interlayer at some skylights. We can... Read more
