First, special shout out to Carolyn Day from Perkins Eastman for getting permission to use their Pro-zoom account for this Greenbuild wrap-up social session, because...frankly...Greenbuild just wasn't the same without all of you.

So, while we can't be together in person, that doesn't mean we are stuck by ourselves. Grab a refreshment and... Read more

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.

Everything I know is from this document. So as I understand it ... an individual building or retrofit is going to change the marginal... Read more

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 Green Commons,

It’s been eerily quiet here since Tuesday night. I’ve been quiet mostly because I just didn’t know what to say. The election results are certainly a blow to pretty much everything we’ve been working for. There is so much we don’t know about things might play out, but I’m feeling a range of emotions ranging from... Read more

Hi All,

Polling the group to see if anyone has experience with Simergy - an e+ based modeling tool?

The tool appears to have features and integration with a lot of e+ plugins that make it attractive - but i haven't heard of its widespread use.

Is anyone successfully using Simergy?

Is everyone else having trouble with a dysfunctionally slow LEED-Online today (i.e., worse than the usual incredibly slow performance)?
