Which sections will be freely visible, and which will be visible only to registered users? Here's what I recall from our earlier... Read more

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:

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

Hi Gurus,

LMN is embarking on a 17-part series to explore a more comprehensive carbon metric via summaries of various topics with lots of link.

Though BuildingGreen has long supported the use of electric hand dryers as a more environmentally friendly hand drying option, the majority of evidence appears to support paper towels as a preferred method of controlling the spread of potential pathogens. 

And even the most efficient hand dryers contribute significant CO2 to the... Read more

Hi all,

We are trying to encourage participation in take-back programs and using recyclable packaging with our vendors and I was wondering how we can add it to specifications.

I did a quick search for the LBNL and other studies that look at this, but didn't see anything... Read more
