can someone explain how/why a credit is achieved under the LEEDv4 , enhanced refrigerant management. my understanding is that the intent is to
"To reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct contributions to climate change" . but option 2 allow for the credit to be achieved simply calculating the effect instead of minimizing it by leak detection and automatic recovery as is done by the GBCA here in Aus.
Is this correct?

Hi David,
Option 2 supports the credit intent by setting a maximum threshold for refrigerant impact, defined as a combination of ozone depletion potential and global warming potential over the equipment's likely life. This allows for some flexibility for projects to find a refrigerant minimization strategy that meets their project's needs.
However, on the NC rating systems, the v4 Reference Guide is clear that the calculations must be completed using default values for the ongoing leakage rate and end-of-life leakage rate. This limits the scope of the refrigerant impact minimization that falls under the LEED credit and seems more geared towards rewarding system efficiency than the GBCA equivalent.
