We're thrilled to announce that, for the first time, the 2025 Summits for each Peer Network will be hosted within one week and in a single location. You’ll get the deep peer-to-peer time you love from a Summit AND some glorious cross-disciplinary time to experience the power of the Green Commons. It’s all happening at the Kimpton Cottonwood, a...

We have a client for whom we are designing a very high performance manufacturing facility, and they want to communicate their building's performance both dynamically and in real-time within their lobby for guests and staff.

We would like to mine the wisdom of this group to see what recommendations we can muster regarding high quality... Read more

Hi folks,

You may have seen this posted to the Green Gurus forum. Paula got some good responses from architects and engineers, but not so much from GCs so she asked me to follow up and post it here. Please reach out to her if you're willing to be included in these articles/reports. Thanks!

Hi! I’m working on two reports about... Read more

As we begin to look into Scope 3 emissions reduction strategies, it's important to understand ways to reduce tranportation emissions to project sites. Is anyone aware of best practices or programs for contractor carpooling to jobsites? I know many of my colleagues travel to work together in one vehicle because of parking limitations, however,...

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.

Hi! I hope that others who were at Islandwood found it as fulfilling as I did. (Janice and I spent the weekend exploring the island on bicycles--we're just getting on the ferry to Seattle now. It was a great little vacation!)

Let's use this thread to share notes and documents from the Summit. Please post your highlights here, or send... Read more

Does anyone know where one can locate weather files (EPW) that has predicted future data for climate change?

Thanks in advance.

Hi: Great to see so many of you at AIA COTE Top Ten last week.  I'm forwarding the message below for those of you who know Marsha Maytum and can contribute to this important effort. Deadline is next Friday June 23rd!Thanks.

Hello, friends,

During A'23, Je’Nen and I discussed our desire to send Marsha photos we have... Read more

We have all these resources out here in the ether but it’s so hard to pull them into one spot! I was asked, last minute to join a client call today to help convince both the client (affordable housing developer) and the mechanical engineers to "stick with" a commitment to 100% electric design that was publicly stated when the competition was...

Looking for an example or case study for a building utilizing a radiant heating/cooling in climate zone 4a. General use type is office with some public assembly spaces, total of 85,000 sf.

As usual, everyone, especially mechanical engineer, is terrified by the thought of "condensation." So far, I read a DGWW case study, "Energy... Read more

Hi Gurus,

It seems odd to think about leases now, during a time when most business are giving up leases or reducing their footprints, but there are still leases going on! Please share this link to any clients of yours who might be interested and sign up yourself if you want to advocate to your clients to consider these leases!

Hi everyone,

Thanks so much to those of you who presented at this years AIA Show & Tell, and thanks again to ZGF for hosting! Here are the slides for some of the presentations. Please do not share the slides outside of the networks unless they are marked "PUBLIC." Hope you enjoy!

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

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

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
