Hi there SCLers,

Hope everyone is safe and healthy. I am posting on behalf of the Steeering Committee to let you know that the Committee has now adopted a Core Purpose Statement for the SCL Group. Please give it a quick read; we will likely sit with this and spend some time internalizing what it means at the upcoming Summit.

Greetings, Green Gurus:

As unbelievable as it sounds, the Environmental PROTECTION Agency has launched a PR blitz in support of their "new use rule" on asbestos. So the BuildingGreen community needs to push back harder. I'm reposting the links to the letter of opposition that Mary Ann Lazarus put up last week. We definitely need more... Read more

Posting at the request of Sara Bayer of Magnusson Architecture and Planning, who will soon join this group:

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? ...

Good morning SDL,

I have a request for all of the supply chain labor folks out there… I would welcome hearing about your experience/stories/pointers you have based on your project work applying the DfF toolkit or other comparable supply chain labor efforts.

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

Hi everyone - in doing a carbon footprint for our firm, does anyone know if buildings that we design as Architects considered scope 3 emissions, or are they beyond the boundary of emissions? LMN's buildings, despite best efforts, are cumulatively multiple orders of magnitude above our scope 1 and 2 emissions. We have never included these... Read more

Here is a fundamental question regarding measuring operational carbon emissions that I'm sure many of you can clarify for me:  Let's say you are considering design options and you want to know the relative contribution of GWP of adding an additional inch of continuous insulation to the building envelope.  The GWP from embodied carbon will...

I'm writing an article surveying and comparing various embodied carbon tools, including whole-building LCA tools. I'm looking for interviewees who have used at least TWO of the three major LCA tools currently in use in North America (Tally, Athena IE, and One Click LCA). If you've tried all three, all the better! If you or someone in your firm... Read more

Hello all,

I need future weather files for a project. We are looking at three years, 2050, 2075, and 2095 using two climate change scenarios, low emissions, and high emissions. I have seen ARUP's Weathershift site that uses RCP 8.5 and RCP 4.5. Are we assuming that 2.6 is not achievable? I would have used this as a low emissions scenario... Read more
