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

Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

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

The memorandum for heads of agencies that was sent out with E.O. 14057 said that the CEQ would issue these standards, but I can't find a commitment to when... 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...

Is LEED Online mind-numbingly slow today for anyone else? Or is it just me? I may give up and try again tomorrow. Frustrating as I was hoping to submit a final review today. :(

Folks, it is with a heavy heart that I write this: Lance Hosey passed away unexpectedly on Friday. 

Many of you know him from the early days of the SDL group, or as an outsized presence at any of the many conferences where we overlap. He's been a list-maker, poll-taker and all around troublemaker in my life for over 20 years; I know I am... Read more
