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!

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,...

First, there was Energy Use reductions

Then there was embodied carbon

Soon it will be refrigerant use/leakage calculations

As coordinators and leaders of project teams, what does this look like for the practicing architect and our collaborators?

I have no idea. BUT I’m guessing someone is... Read more

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

Thanks in advance.

We should probably agree on the correct spelling for what we at BuildingGreen are calling "BITuser." I noticed that on the Salesforce portfolio screenshot provided by Dennis, it's spelled "BIT User."

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... 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 all,

I'm curious if anyone has insight as to the "New Federal Building Performance Standards" that were announced in May of 2021 and then referenced again when E.O. 14057 came out. 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

I'm looking to compile an outdoor weather station for a local project, and we'd like to add local outdoor CO2 information to our data. I usually work with Onset HOBO products, but they don't offer an outdoor CO2 sensor. Their weather stations can take data from any CO2 sensor with an analog output - does anyone have any suggestions?

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. :(

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)

Acceptable regulations for... Read more

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Should housing be affordable? Or should it be sustainably designed, built, and operated?

When you put it like that, the question sounds absurd.

But the idea—usually unspoken—that sustainability wastes precious time and resources is painfully common in the... Read more

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...
