hi @jacobracusin great you’re looking into this. We relied heavily on the PEP database for some research in Rwanda. Results varied significantly from TM65 estimate x10 higher in some cases and 1/2 as much in other cases. There is still a significant lack of data in some areas too and identifying Functionally Equivalent systems was difficult. Happy to share any more information.
TM65.2 is coming out at some point, being led by Elementa, and has some great graphs showing the huge variation in manufacturer data.
At that time, for my work, refrigerant leakage dominated all the results due to the lack of availability of low GWP options so we were less concerned about getting the equipment spot on
