Hi, all. We missed you at the standing check in today. We have a couple of questions for the BG team:

1. What is the timing criteria you need for Best Practice content? We need to back into a deadline on submissions and believe your critical path timing will help define ours.

2. Can you elaborate on what LEED User/BG content may... Read more

As part of my goal to increase staff education frequency, I'd like to introduce some training and certificate programs into the mix. I wonder what programs others have recommended to staff? Not just attending conferences (low accountability) or CEUs, but things like the Parsons Healthy Materials Certificate, or Phius/PHN passive house... Read more

Hi SDLers! I hope early fall is finding you well.

There is a current opportunity to make a difference in the campaign to reduce use of toxic flame retardants.

Arlene Blum and the Green Science Policy Institute, whom many of you know, are currently organizing a campaign of support for the CA State Fire Marshal's proposal to allow... Read more

Hi - some of you may have received an invite to the White House for a 3-hr session to continue the discussion on the Net Zero Emissions building that they released earlier this year. This discussion will be on embodied carbon. I have no idea who the invite went to. If I beg I may be able to go, but if there are plenty of other Architects that... Read more

Hello everyone! I’m happy to be re-joining the group after a two year hiatus.

Pre-pandemic I got to participate in a few winter summits when I was Sustainability Director at Overland Partners in San Antonio. I’ve recently joined Mahlum Architects in Portland and I’m excited to re-engage in the conversation, this time from the West Coast... Read more

Can anyone recommend waste haulers and processing facilities that are LEED compliant for processing commingled waste in the DC / MD area?

I know this is the Sustainable Construction Leaders and not the LEED Construction Leaders, but with waste management being such a big part of what we do, I wanted to crowd source a request for help.... Read more

I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

Has anyone done any museums in which they hired an independent QA/QC specialist? Or perhaps, your firm offers QA/QC services and experise in this area? If so, could you please reach out to me? I'm wondering what firm you used and what your experience was. Was it worth the fee?

Colleagues, 

Have any of you had the opportunity to implement the Tesla solar product? We're in learning more about the product, its track record, any concerns we might need to know about. Would love to hear! Thanks. 

We all know the climates are shifting, and the ASHRAE standard that gets invoked for energy codes is shifting along with them--though not in perfect sync.  Louisiana is leaping from ASHRAE 90.1-2007 energy code to 2021 IECC (boom!).  The 2021 IECC as published uses relatively old climate maps; for Louisiana, at least, the same as the 90.1-2007...
