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...

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

Hi all,

I'm curious how various firms are approaching their own office projects, re green building certifications. I'm especially interested in medium-large firms that have multiple offices, but policies and processes from small firms may still be instructive.

Do you have a firm-wide policy or is it a case-by-case thing? Has... Read more

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

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

Hi everyone,

We're pitching a green wall to a client for a project in NYC and are looking for recommendations on systems/companies.  We've done them locally, but the company we've worked with only services the Boston area.  There are so many companies out there now that we'd rather go with one that's recommended.  Thanks in advance for...

Hello! Does anyone know of any general contractors who produce a CSR? Is anyone aware of any general contractors who have an ESG rating? If so, what company is being utilized (i.e. EcoVadis) to get the ESG rating?  

My name is Douglas Flandro. I am the sustainable design leader at CambridgeSeven in Cambridge, MA. I started my career in film and theater design. I moved into museum exhibit design with a graduate degree in interior architecture at the Rhode Island School of Design in 2003. I still design museum exhibits for science museums, nature visitor...

Ventilation fans, kitchen range hoods, and laboratory fume hoods can use significant amounts of energy from both the fan motor and from venting heated/cooled air out of the building—air that then has to be replaced and conditioned by energy-intensive HVAC systems.

My dear collegues,

As I'm sure is true for many of us, the events of the past weeks (months/years/decades...) have emphatically reinforced to me the need for a radical shift in how we meaningfully address JEDI in what we do. One (admittedly small) step I've been thinking about are the statements of reconciliation that have become more... Read more
