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?

Fellow SCLers,

This is a small ball item, but I recently had a conversation with a safety glove manufacturer called Traffi. They make PPE, but in particular they have a line of gloves that they promote as carbon neutral. Their organization's operations are offset with retired RECs, but one line of their gloves, LXT, is offset by a... Read more

Hi - We have some projects within reasonable reach of ILFI's Zero Carbon Certification, which will require purchasing some off-site renewable energy. As a State Building Code Council member, I'm also eyeing the Zero Code which we will seriously consider in the next 12 months; this also requires a purchase of off-site renewable energy.

In trying to help a client write a case study on avoided carbon by using slag and flyash, I am having trouble finding a one for one equivalency that can be verified.

I have found for one pound of flyash, one pound of carbon is saved - but I can't verify that.

Appreciate the feedback!

Were we given any warning that LEED Online and USGBC.org would be down for a week?  

Fellow Sages,

Phil has a very interesting posture about AI... Read more
