The LEED reference guide is quite misleading when it comes to commercial refrigeration systems. At first glance it appears that this only needs to be addressed if the project is registered as a BD+C: Retail project...and if the project is registered as a BD+C: New Construction project it does not apply.

However, the last paragraph on page #450 of the v4 BD+C reference guide states "Non-retail projects that have commercial refrigeration systems....both commercial refrigerataion and HVAC refrigeration system requirements must be met to achieve credit compliance".

Since this is true, I wonder why 'commercial refrigeration requirements' are specifically listed within a dedicated RETAIL section??

We met the requirement on my project, but this is an instance where I learned from a GBCI review report rather from the LEED reference guide. Dangerous time to be learning LEED, that's for sure!
