Has anyone done a LEED Homes and a NGBS certification and have insight into the differences, challenges, etc between the two?

Hi all,

We're doing some tool-related soul searching at WRNS and some folks here have raised Cove.Tool as a potentially interesting addition to our library. I'm looking for any insight you all can provide. Cove has come up various times, but curious if there's been any change for the better/worse in the past few years.

We had so much fun at our Contractor coffee talk that I reached out to our MEP friends to see if they would set up something similar.  And they have agreed to host a talk on Thursday December 2, at 1-2pm EST.  They will talk about decarbonizing buildings, on a schedule that keeps us under the 1.5° C limit and will also address strategies for...

Hi folks,

It came up on the Regional Leaders call this week that many people aren't aware that we added a link to the BuildingGreen Communities in footer of BuildingGreen.com. So if you want an easy way to get to the forum page, other than clicking on a link in an email, there it is! (Thank you, Stephen Endy!)

Hello, 

I am struggling with understanding if I should be using Annual Marginal Emission Factors (MEF) or Annual Average Emission Factors (AEF) for evaluating different building design decisions.

Does anyone know about temporary flushout equipment that could be used to augment a building's systems to get additional CFM of OA during construction?  For our non-laboratory type projects the flushout period ends up being too long, especially in either humid summers or frigid winters (Pennsylvania).

Hoping that some of you on either... Read more

Has anyone worked with Vidaris for LEED certification and have a contact there? If you want to direct email me with feedback on the experience that would be helpful as well.

Hi All,

Attached are the meeting notes from the Carbon Group's 2/26/20 -- also in the PDF are the slides presented in the 2/26 meeting.

Before our next meeting in late March/early April, we are looking for input on the following topic related to tracking and reporting carbon:

Hi all,

The Sustainable MEP Leaders are assembling an industry push to expand the availability of embodied carbon data for MEP equipment. Our first steps are to send a letter to industry announcing a call to action and future educational webinars on the topic, the current draft letter is attached. In a similar manner as the...

The overwhelming majority of wallcoverings are flexible vinyl, laden with all the life-cycle concerns that come with PVC. Products used to contain orthophthalate plasticizers—which make up a large percentage of these products.
