All,

I'm looking for a quick methodology to estimate GHG emissions from refrigerants on a per SF basis. Are there any benchmark studies or quick calculators similar to the embodied carbon study? https://carbonleadershipforum.org/embodied-carbon-benchmark-study-1/

Thanks,

Josh

ASHRAE 228P has a default leakage table 9: Annual Leakage Rate of Refrigerant Mass Charge Per Year based on equipment type. But you’d need to know the refrigerant charge and equipment type. F

This report from PAE for City of Seattle has some guidance about Refrigerant Emissions based on system types, fittings, etc and includes a number of building type case studies. https://www.seattle.gov/Documents/Departments/OSE/Building%20Energy/SEA_Refrigerant_Analysis_May2020.pdf
