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: 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

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

We just wrapped up an awesome Winter Summit at Gulf State Park in Alabama. I'll be posting flip chart pages and notes here--we can use this forum to continue the conversations. 

Apologies for the flurry of emails, but it seems best to start separate threads for each topic. If you'd rather limit the flow, you can switch to daily digest... 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

Faucets with high flow rates waste water—not to mention the energy used to treat and deliver it to our buildings—and the additional water stresses our wastewater treatment systems.

Welcome to the quiz portion of Know Thy Client: 9 Un-Green Strategies for Delivering Better Buildings

Hello Sustainable Construction Leaders,

It's come to our attention that although we shared the slides from last fall's all-network Show & Tell in Atlanta, we neglected to include the presentations from the SCL Summit itself. Since we believe in "better late than never," here they are!

As a reminder: we have permission from... Read more

Hello Everyone,

Here is the information and invitation to complete the SCL Demographics Survey! If you have multiple company colleagues on this forum (you can check in the group list here click "Group members" tab), please coordinate to have only one of you submit survey responses.

If you would you like to gather your answers... Read more

Hello! 

We have several projects that are either pending ILFI Zero Carbon certification or the owner is planning to purchase offsets to cover construction emissions. Thus far, I have not considered this in our corporate footprint reporting. However, we are including A5 emissions whenever feasible and multiplying that performance over the... Read more

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

Thanks in advance.

We have a client who is asking us to design a roughly 10 ksf Wellness Center for PHIUS 2021 certification.  The program includes several high density assembly type spaces - roughly 300 person peak occupant load for the building.  The Criteria Calculator that the architect showed us puts the building peak cooling load at 4 BTUH/sf (3000 sf/ton...

Hi all,

We have a project in New Orleans that needs to meet the GSA Inflation Reduction Act (IRA) requirements and submit EPDs. For our concrete, there is only one manufacturer that meets the requirements and is more than 50 miles away (according to EC3). Does anyone have tips on attempting to talk to local concrete manufacturers about... Read more

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more
