Hi all,

After almost eleven years in this group, today is my last day at Perkins Eastman as I move on to a new step in my career at JLL (wish me luck!). This group has been invaluable to me both professionally and personally, and I have loved connecting with so many of you over the years, over the course of so many events! I hope to make...

The construction sector’s take-make-waste approach to materials needs an overhaul. Materials and construction account for an estimated 11% of global greenhouse gas emissions annually. At the other end of the life cycle, demolition in the United States annually generates 90% of some 600 million tons of construction-sector debris. Getting trashed... Read more

Green gurus!

We're getting some interest from clients abroad on two specific materials which we don't have experience with here in the U.S.:

1) Cross Laminated Timber (CLT)

and/or 

2) CarbonCure concrete

Anyone willing to share lessons learned on these material either here in the forum or offline? Or point me... Read more

All,

I'm looking for a quick methodology to estimate GHG emissions from refrigerants on a per SF basis. Are there any benchmark studies or quick calculators similar to the embodied carbon study? https://carbonleadershipforum.org/embodied-carbon-benchmark-study-1/

Thanks,

Good morning all,

I'm new to the forum and I am really happy to be here. For the last year or so, I have been working to advance high performance design at Flad, grappling with so many of the issues discussed in this forum. Especially in the context of recent times, it feels really wonderful to join a group of people dedicated to helping... Read more

If you have not already received an invitation, and you play a sustainability leader role - either formal or informal - in a mid-sized (>40... Read more

On our Contractor Coffee talk a few weeks ago, Emi LaFountain (Turner Construction) brought up the idea that there was a lot of blue stain wood that are being landfilled instead of used, and suggested that maybe the designers among us could find a way to turn ugly into beautiful.

I had never heard of this issue, but I was on a call the... Read more

Hi all! During our Contractor’s Commitment call last week Amanda made a great point about sharing of waste data to gain some realistic, current metrics. Just like I assume many of you, we have both seen a decline in successful diversion these last few years and our companies’ overall percentages have taken a hit. In an effort to gain a full...

I am diving back into Sefaira for the first time in a while, and the program still seems to be missing the ability to account for automatic daylight dimming in energy savings. Previously I had used an LPD reduction equivalent to emulate the savings automatic dimming would provide. Has anyone done a similar work-around? 

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!

I've been seeing Armstrong's DC flexzone ceiling system at Greenbuild for many years. I'm working on a net zero project with LED lights and solar panels. In theory, the transmission losses in going from DC power from panels to AC for the building to DC for the lights would be eliminated. But does anyone actually have experience using this...
