Hi folks,

If you're registered for the Summit, you should have gotten this message from me separately, but I wanted to post it here too to be sure. It would be great if everyone coming from out of town could stay together! We've achieved critical mass in terms of Summit participants--this is going to be a great and impactful gathering!...

Hi,

Has anyone used a sustainable product that complies with the EQc Low-Emitting Materials requirement that is a general construction adhesive similar to Liquid Nails? I've checked the Mindful Materials website and can't find anything. I found Red Devil General Prupose Construction Adhesive on UL Spot, but have never used it before. Any... Read more

ICYMI, this washington post piece reminded me of our summit conversation last Friday about architecture's/SDL's role in reimagining the world post-covid through innovating our practice. 

The article contains some compelling quotes from several visionary architects (fascinated that it's mostly big-A architects, largely bypassing input... Read more

We have all these resources out here in the ether but it’s so hard to pull them into one spot! I was asked, last minute to join a client call today to help convince both the client (affordable housing developer) and the mechanical engineers to "stick with" a commitment to 100% electric design that was publicly stated when the competition was...

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

Acceptable regulations for... Read more

I really enjoyed last week's "Integrative Solutions Jam - Getting Better Materials Into Projects".  Thanks BuildingGreen for setting that up.  One of the great parts were the break out groups, where 4 of us could dig into various topics more deeply.

We got into a conversation about circularity and material re-use and Laura Soma with Gly... Read more

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.

Because board insulation is used on the building exterior, it is not always subject to the same material health and emissions requirements as batt insulation used inside the... Read more

We are pursuing sustainability goals (and documentation of those goals) outside of any certification/rating system for a current project.  However, we have set up a criteria list of goals by following strategies/credits from many of those systems (LEED v4 EPDs, SITES v2 threatened tree species, WELL v2 mindful eating, etc.).  This approach is...
