We recently purchased two indoor air quality meters in the $200-$300 range and find that they never agree, not even close. I would like to find out what other people's experiences have been, and if they have tested affordable models that... Read more

I received this email from Cathy Higgins at NBI, and thought some of you may know the right folks who might be interested:

Hi colleagues,

You are exactly the folks that might know a high-caliber person to join NBI’s team. We are looking for someone ideally based in California but could be elsewhere with... Read more

Has anyone completed an LCA for an engineering structures lab, particularly one that has a strong wall and strong floor? 

This article just came up in my news feed. I thought you’d all like to read it. I will point out that C&D-specific MRFs have told me that they are really good at single-stream C & D waste, as long as the drywall is pulled out.  Any drywall in a single-stream C & D dumpster ends up in the landfill. Drywall just breaks apart and gets... Read more

Hi all, has anyone come across a comprehensive (and recent) study looking at how long buildings actually last (beyond Stewart Brand)? I know of plenty that look at the benefits of reuse, but none that look at existing building stock and how much has been reused vs. demolished. 

As we start looking at embodied carbon metrics, I can't help... Read more

As if you weren't worrying enough already, here's a little something that I ran across through monitoring activity on the American Society of Healthcare Engineers discussion boards:  https://www.id-hub.com/2018/10/17/hospital-plumbing-reservoir-resistance-interview-amy-mathers/, "Hospital Plumbing as a Reservoir for Resistance".  This is both a...

Dear All!

Crowdsourcing here to see if anyone has access to two LCA's that can be used to compare functionally equivalent consumer products: a fossil fuel powered to a battery one?  (A good product might be a car or stove, or a heating system with a boiler compared to a heat pump, perhaps?  Needs to include the B-use phase probably...)...

Hello everyone! 

A small subgroup SCL members have been working on writing a response the presentation Wes Sullens gave us at the Summit this past winter. It's been a long process but the letter and all it's reccomendations are drafted and ready to present. The group felt it prudent to post the response here first for a short public... Read more

I was shocked to see this new research. Bad news is that acrylic paints are causing 58% of the microplastics pollution in our ocean. Yes, they are plastic. A recent study by Environmental Action, a Swiss-based scientific research firm, shows us that acrylic paint's role in plastic pollution is much greater than most of us realize. The good news...

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

Pipe that delivers domestic water in North America is typically made from copper, chlorinated polyvinyl chloride (CPVC), cross-linked polyethylene (PEX), all of which present environmental challenges. Bimodal polyethylene  (PE-RT) and polypropylene (PP) are potential alternatives with lower climate and health impacts.
