FAQs about EAc6 :

Are HCFC or HFC refrigerants considered CFC-based refrigerants?

The refrigerant type I need to enter is missing from the credit form. What should I do?

How can I determine the leakage rate of my equipment?

Should all commercial refrigerant equipment be accounted for, including both upright and under-counter? What about walk-in refrigerators? Ice makers?

I'm working on a renovation project and we'll be keeping some of the existing equipment. Should we include these systems in our calculations?

What is the required timeline for completing a CFC phase-out for this credit?

Are refrigerant GWPr and equipment life (years) typically shown on cutsheets, or are default values sufficient for this credit?

The closest I've seen is a calculator from Trane: https://www.trane.com/content/dam/Trane/Commercial/global/products-systems/design-analysis-tools/calculators-and-charts/LEED-v4-enhanced-refrigerant-management-calculator/EAc4Calculator_LEED-V4_PROTECTED_IPCCv4_GWPs.xls

Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are inherent properties of the refrigerant that is selected. These values are listed within the LEED reference guide. If the refrigerant is not listed within the reference guide you can perform a google search to find this information. ODP and GWP are not typically included within the cutsheets.  Equipment life is taken from the table in the reference guide, or 10 years if not listed. I would not expect this info to be included within the products cutsheets.  Good Luck!
