Hello SCL peeps, 

Thank you to all the people who filled out our 2021 event survey. Your feedback did help us narrow down the options, but it was still inconclusive about whether there’s enough interest in doing an SCL-only Summit. 

To stay on schedule with our planning (and to make sure the event will pencil out financially), we... 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

Hi: SD Leaders.  It was so nice to see so many of you at Greenbuild in Chicago. By now I'm sure all have seen the announcement of the release of the Fourth National Climate Assessment Report vol 2.

I think they look great - thanks to BuildingGreen for setting this up!  A few comments/questions:

Hi! Over the last 10 years, the firm where I work in Boston has predominately designed housing & senior living projects in the the Boston Metro region, with the occassional project in NH, CT, RI, and NY. We have built projects as far south at DC, but never designed anything to my knowledge in California in our 55 years of operation. A... Read more

Conveniently, we have also just launched the new Peer Networks Hub on BuildingGreen.com, with a Calendar page where you can see all upcoming events (and a link to recordings of past events). You... Read more

Was anyone else surprised to see ASHRAE 228-2023 using eGRID Subregions for both the Regional Electricity Source Energy Conversion Factor and Regional Electricity Greenhouse Gas Emission Factors? In the past I have used eGRID sub-regions but also State and local utility conversion factors depending on what energy or operational carbon story I... 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,

USGBC MA is doing a study on the cost of net zero energy buildings in MA.  I’m wondering if you all have any data to share on plug loads in ZNE projects. I’m looking for single family res, 2-4 unit residential, +/- 60 unit residential, 10-12 story office, and k-12.  The engineers have presented initial results and their... Read more

Untreated rainwater leaving a developed site is effectively a chemical spill, laden with pollutants that include oil, sediment, heavy metals, nitrogen, and phosphorous. The heat carried by stormwater is also harmful to fish and other aquatic organisms.

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