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

Does anyone have an opinion of Autocase?    https://autocase.com/

I had not heard of this platform before.  Their website says that some firms in the group are customers / users.   Website does not do a great job of describing exactly what they do.  Is there value?

Thanks,

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

We're wrapping up a multi year project that went through multiple design changes, leaving us with a ton of material samples.  Does anyone know of a good place we could donate these samples to, to keep them out of the landfill.  I'm in the greater Seattle area.  Thank you for any suggestions.

All, today is the day I had committed to sending out the DRAFT request to equipment manufacturers of what is needed for full electrification.  I apologize that I didn't have time or focus to get my thoughts together till now (I had intended to share this with Chris and others prior to sending to the full group, but just didn't get my thoughts...

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...

Does anyone have a recommendation for software that helps organize and track product and material selections for projects? 

Thanks!

I'm exploring the use of phase change material for a project. Specifically, looking at the BioPCM/ENRG Blanket product. I see on their website that ZGF used it at University of Washington. I'd love to hear any feedback from folks who have used it, and more specifically how your energy model and MEP engineer accounted for it. Thanks!! https://... Read more

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

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
