They say that Louisianans are often late to the party but enjoy catching up.  The state, which had been stuck on ASHRAE 90.1-2007 (commercial) and IECC 2009 (residential) and has just adopted legislation jumping to IECC 2021 / IRC 2021, and commits to automatic upgrades with each 3-year code cycle.  This means we join CA, OR, WA, MA, and VT--...

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Hot spots: they might sound like fun places to hang out and have a drink—but in green building, they’re actually a bad thing. Something you track down so you can get rid of it. Kind of like being an environmentalist bounty hunter.

Life-cycle assessment (LCA) is... Read more

"The man with one watch knows what time it is; the man with two is never sure."   --Segal's Law

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

Dear SLD-ers,

We have a project team considering the use of copper cladding for a high profile project in Vancouver. The preference is to use pure copper that is pre-patinated and does not have additional coatings.

We are attending a CEU from the Copper Development Association to understand options and environmental impact, but we... Read more

Hi everyone!
I've seen a lot of claims over the years of living walls or planted buffers that can mitigate *outdoor* air pollution and have always assumed there's no real scientific basis for that idea, unless we're talking an actual forest that's 10s of feet thick. Am I wrong? Are there examples of living walls that actually have been... Read more

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

ENERGY STAR is a voluntary program for high performance appliances and this is a huge opportunity to begin the decarb transition... 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...

Hello SCL,

Quick reminder to sign up for our SCL Summit in May! True to usual form, we ask what’s important to YOU before we finalize an agenda. In the next couple of weeks, we will be sending out a draft agenda and asking for your feedback. Sign up now so your voice will be heard. Initial ideas so far have included:

We are coordinating an effort to produce a "Building Reuse Practice Guide for Climate Action" for the AIA.  This is intended as a resource for architects working on major renovations and adaptive reuse, with a focus on reducing energy use, lower embodied carbon, electrification, and adapting to a changing climate. We are looking for around 5... Read more

Hi all,

We are looking to study Passive House on a couple small multifamily projects. Our understanding is that WUFI Passive only integrates with SketchUp at this time. Our BIM manager has been trying to find an example of a firm that works in Revit and uses WUFI Passive, to point him in the right direction on workflow. I offered to ask... Read more
