I am currently making use of the Non-Energy sector to keep careful track of F gas fugitive emissions associated with equipment that utilizes the refrigeration cycle, such as refrigerators, ACs, heat pumps, and more. The equation I used was offered to me by CARB and relates F gas emissions to the charge size and leak rate of the equipment type, the number of units, and the number of retirements. For the latter two, I link my nonenergy calculation to the stock of equipment in the Demand area.

My model's data set is admittedly large, however, LEAP calculates through the Demand area with quite a good pace, slowing to a crawl for the Non-Energy sector. Is there an inherent property of the Non-Energy sector's back-end code that might explain this? And is there anything I can do to alleviate the run time? I was thinking of perhaps running the calculation in the key assumptions area, and then just linking the Non-Energy sector to the key variables, however, I wasn't sure if this would be better? Please let me know any advice!

Thank you,

Josh
