The Winter Summit participants have had this for a few weeks now, and no one has screamed about anything being inaccurate, misleading, or too revealing, so it's time to share the latest Summit report more widely. 

Per our long-standing policy, this report can be shared outside our "safe space"--it's a great way to share the wealth 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 folks,

Some of you have seen me do a 5-minute presentation on an initiative to divert urine from wastewater. That team is now developing a building-scale urine treatment technology with support from the National Science Foundation's Small Business Innovative Research (SBIR) award. 

In order to learn more about the sustainable... Read more

Hello Green Gurus!

ILFI’s annual Living Future Conference is coming up, so we thought we might host a (virtual) Show & Tell session of 5-minute versions of peer network members’ presentations like we often do in conjunction with Greenbuild. First we want to see if this is of interest to you all. Please take 30 seconds to let us know... Read more

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...

Concrete and other cementitious materials have both environmental advantages and disadvantages. As builders and designers, should we be looking for alternatives or embracing concrete over competing materials?

This special report takes a look at how these materials are made, presents the key environmental considerations relating to their... Read more

I'm teaching a LEED GA study group and was rambling on the differences between CIR and precident-setting LEED Interpretation (that gets posted in the addenda library and all). Then I went onto LEED Online and was showing how those are submitted... but can't actually figure out how a LEED Interpretation would be submitted. Has anyone done this... Read more

This question came to me via our mutual friend Josh Jacobs, but while interesting it's a bit out of my range of expertise... 

In short, a critical materials assessment specifically focused on airbourne byproducts from a manufacturing process that would be first-of-its-kind in the U.S. 

I'm in search of anyone who's done a LEED ACP Pilot Credit. It's unclear to me whether using one of these pathways replaces the way the base prereq or credit would function in the rating system being used by a project seeking certification or if it's a strategy to achieve Innovation in Design credits only. The documentation I've been able to... Read more

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 ...
