Hi all,

Looking from insights from anyone who's been through WELL certification before - we've got a lab/office project pursing WELL down in Florida that is struggling to meet the turbidity level requirements of the WELL W01 prerequisite, specifically with the hot water supply, and we're not sure how to best remediate the issue.  Should...

Hello fellow SD leaders,

This is a quick note to re-introduce myself to this group. I am a lapsed member from the original tribe of 2008 who has found my way back on a trail of bread crumbs left by Nadav (thanks Nadav!). I'm just glad to be back amongst my people, sharing and learning from you all, as we help each other to get where we... Read more

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!...

Figured I'd throw out this topic to the hive mind!

We are working on a project in the Midwest that involves taking down and replacing an 100-ish-year-old brick building. We are hoping to find a way to salvage and reuse some of this brick in new construction. I'd love to do an LCA comparison showing the benefits of salvaging the brick vs... Read more

We're consolidating our office and I find I have back issues of EBN going back to 1999 on the bookshelf. Any use for these other than compost?

Section 901.5.1.3 of the 2018 IgCC includes a requirement that "A critical review shall be performed by an external expert independent of those performing the LCA."  I'm curious as to what other's experiences are with having an external expert review an LCA - how does one find such an expert?  Do you have any favorites that you'd recommend? ...

The Sustainable Design Leaders network and Summit events started over 10 years ago, when a group of sustainable designers realized that the struggles they faced and the goals they strove toward were shared by many... Read more

The overwhelming majority of wallcoverings are flexible vinyl, laden with all the life-cycle concerns that come with PVC. Products used to contain orthophthalate plasticizers—which make up a large percentage of these products. Phthalates are not bound in the material and can slough off in dust, exposing occupants during everyday work or play.... 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...

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all. There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... Read more

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:

Even though freight transport is something like 7% of... Read more

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
