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

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

Dear all,

A mechanical engineer on a healthcare project we are working on has asked for help in dividing the ventilation calculations between ASHRAE Standards 170 and 62.1; can anyone here help shed some light on it?

"This is the first time I am working on LEED for a hospital and I am not sure how the template wants me to show... Read more

I’m a volunteer member of the ASHRAE 209 ("Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings”) Committee.  Are you familiar with ASHRAE 209? It was first published in 2018, and it outlines a process for incorporating energy modeling into the design process. 

From the forward: 

 ASHRAE Standard 209... Read more

Furnaces heat air that is then distributed through ducting and warm-air registers.

Approved by BuildingGreen

Products approved by BuildingGreen include the highest-efficiency, sealed-combustion furnaces and high-efficiency wood or multi-fuel furnaces. A multi-fuel furnace uses several sources of energy such as wood, wood-pellets,... Read more

Greetings to all of the sustainability leaders in the Green Commons!

Note: This is a message about politics, which we generally try to avoid in our safe space--but in this case it’s directly tied to climate action so I feel good about sharing it. Feel free to let me know or check in with the BuildingGreen folks if you have concerns or... Read more

So every year about this time I get to spend many lovely moments with our AIA 2030 Reporting data. In order to make the data useful the CBECS baselines/National baselines aren't great in telling us how we did.

For about half our 15 projects that we report in the average year - performing arts, convention, data science schools, etc - a... Read more

HI All,

I have been tasked with putting together a cost comparison of doing a LEED v4 Gold building vs. making that same building Passive House. Obviously they are two different systems, with two different outcomes, and it's not really intended as a total apples to apples cost comparison, but more a value comparison for a developer....

For those folks who are on our retrofit electrfication roadmap post-palooza-sub-sub-working group ;-) , I thought you might be interested in these three guides just released from BEI in collaboration with S. Winter Associates.

Here are the three Playbooks:

Hi SDL: Check out this great interview with Paul Hawken and  COTE members Gunnar Hubbard and Kira Gould. Lots of inspirational ideas about the importance of the built environment in carbon drawdown:
