Glazing connects occupants to the outdoors, but with so many opportunities for air leakage, poor insulation, and thermal bridging, glazing is the primary weak link in building energy performance.

BuildingGreen approves glazing that offers strong energy performance properties for a variety of... Read more

I looked through the forums and was surprised to see that from what I can tell this 2018 article from Yale I'm going to share here has not been discussed previously.  It basically says that FSC is not trustworthy, ineffective, and greenwashed, as critiqued by the likes of Greenpeace and others.

I would like to hear from someone in the... Read more

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.

The documentation I've been able to... Read more

Hi - we're working with the University of California Office of the President to put together low-carbon case studies. The two types we are looking for now include 1) a low-carbon TI (not a full building gut/renovation), and 2) any that involve the circular economy (in this case not just building reuse but product reuse) which could include...

Hey Gurus. Might anyone have experience, or thoughts, with regard to establishing an energy use baseline for a new advanced manufacturing facility we are working on for a regional technical community college? This type of academic facility is so relatively new, the program doesn't fall into the typical "College/University" building type from ...

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...
