Hi All,

I have a client interested in exploring the development of their own custom framework to address environmental, health/wellness, and data security, among other parameters, but would also like to have it audited by a 3rd party.

Leveraging ISO 14001 could be one option. I also understand that GreenCirle certifies a few... Read more

Has anyone found any options to recycle safety vests, or discovered an upcycling option for them?  We are about to replace all of our vests company-wide and will have thousands that we don't want in the waste stream and we don't want to be reused as safety vests.  Any thoughts or ideas would be great!

Thanks and I hope everyone is... Read more

Does anyone have language from an RFP that had specific performance criteria included that they could share? Such as a specific EUI target, detailed language about net zero, passive house, etc.

In a recent e-mail to BuildingGreen subscribers, Paula Melton pointed out that USGBC has opened the call for suggestions for LEED v5.

Every day, I encounter dripping skepticism from building owners about LEED for New Construction, because of the many many times that the fanciful outcomes of energy, water, and daylight models bear little ... Read more

Hi all!

I've heard several people talk about developing tools for assessing/codifying a client's values for a project as part of an integrated design process (ie. a set of questions, survey, etc.). Would anyone be willing to share?

This just in from Berkeley Earth. The definitive report on 2023 global temperatures. Lots of incredible graphs to peruse but the news is pretty incredible. Actual temperatures far surpassed predictions. "At the start of 2023, we foresaw only a 14% chance that 2023 would become a record warm year, and only a ~1% chance that 2023 would reach 1.5...

As we begin to look into Scope 3 emissions reduction strategies, it's important to understand ways to reduce tranportation emissions to project sites.

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
