Gypsum is calcium sulfate dehydrate, which is mined or produced as a byproduct of flue gas desulphurization (FGD) from coal-fired power plants. FGD gypsum may contain trace contaminants from coal processing, but not enough to represent a hazard to users. Years ago, some imported products created indoor air quality problems that required...

Hi All, this is primarily directed at our Sustainable MEP folks, but please anyone with insight feel free to weigh in.

I am increasingly seeing designs and specifications asking for Passive House levels of airtightness as verified by blower door testing, but with traditional ventilation system designs.

Hey y'all,

Since it's now past September 8 when reporting was due, I'm thinking all those that were going to report as part of this round have now done so. I know AIA will assemble an industry-wide report, but I'm also very interested in the less polished conversation that allows all of us to trade experiences and just see how this went... Read more

Hello SCL! We are excitedly planning for a return to in-person SCL Summits. In the past we've scheduled our Summit for the day before Greenbuild, but that day is Halloween and we understand the importance of spending that time with family. We are exploring a January 2023 option for this Summit instead, and are hoping to return to our usual... Read more

All,

I think there may be more than a few people interested in an article I co-authored titled Comparative whole building life cycle assessment of renovation and new construction. It is now available in the journal Building and Environment. Fortunately we have a link that gets you past the paywall that is good for 50 days. If you have... Read more

I'm looking for successful examples of net-zero, Living Building, or similar office buildings that are NOT owned by highly-motivated organizations like RMI or the Bullitt Foundation (or one of your firms).

We are looking to team with a developer on a small-mid-size office building that will house our new office with us as a tenant (no... Read more

I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

Can anyone point me to a (dream?) resource listing effective R-values of various wall assemblies?  We are trying to find a cost-effective R-40 wall assembly for a one and two story public middle school targeting net zero energy in Oregon.  Referencing Seonhee's "thermal bridging" thread in late April, I used Therm's native drawing feature, but...
