We have a really great webinar set up for Thursday, Oct 25 at 2pm eastern. This one is based on the 5-minute presentation from Heather DeGrella at the Summer Summit--our jaws were on the floor when she presented it there, and we were hungry for more.

This question of what equity looks like in project design is one I have been musing on for a while now, and I was excited that several of us were able to talk about it at the SDL Summer Summit earlier this month.  That conversation has prompted me to post here, asking what all of you think equity looks like in project design... with a few...

Hi All - I wanted to share out the All For Reuse initiative below by two peers in the sustainable materials management network. I know some SDL have already done much research on this from quite a few angles, and those with LBC experience probably even moreso in practice. 

Frances Yang (Arup) and Andrew Ellsworth (Doors Unhinged) have... Read more

I believe that Lindsay is in common cause with all of us here on this forum, and will provide meaningful built-environment contributions to COP.

Andrea first became familiar with BuildingGreen in 2010 when she and her husband moved to Vermont and built their own passive house from the ground up. BuildingGreen’s president Nadav Malin heard about the project and asked if the staff could take a tour, and the rest is history. She joined the BuildingGreen team part-time in 2011 to work on...

Hi All,

I want to share this report, released today, that I and some other folks on Green Gurus have been working on.  The report dispels the myth that Zero Energy Buildings cost more (specifically in Massachusetts) and it goes further, making the case that Zero Energy Buildings are actually great investments.  Take a look, tell us what...

Discarded tires are an environmental disaster, and finding a beneficial use for them is a high priority.

BuildingGreen does not approve any flooring product that is made with tire-derived rubber, though some products may be appropriate for exterior use.

Hi All,

We are trying to make a case for hiring a full time sustainability specialist in our firm, and one of the arguments we want to use is that the ratio of sustainability specialists vs the ratio of full time employees in our company is quite low. That being said, I want to have an understanding of where other firms stand with this... Read more

Pint-flush and non-water urinals can save tens of thousands of gallons of potable water per year. A single non-water-using urinal can save more than 10,000 gallons of water per year compared with the U.S. EPA standard of 1.0 gallon per flush (gpf).

When older 3.0 gpf urinals are replaced, the savings can be as great as 50,000 gallons... Read more

Hi all,

I've tried a couple of different search terms for the forum but haven't been able to find any past conversations on electrochromic glazing yet (which makes me suspect I might be missing something...).
