FAQs about EAc8 :

We don’t control tenant supplied supplemental cooling equipment for uses like server closets, data centers, etc. Are we required to address the tenant equipment for the credit?

Are HCFC or HFC refrigerants considered CFC-based refrigerants?

The refrigerant type I need to enter is missing from the credit form. What should I do?

My building uses a variable refrigerant flow system. Do I have to account for refrigerant in the piping runs in the credit calculations?

We haven’t experienced any refrigerant leakage in our systems for the past 5 years. Can we use a refrigerant leakage rate of 0% in the calculations?

EBOM-v4 EAc8:Enhanced refrigerant management

Commercial Refrigeration Systems

I would like some clarification on what LEED considers a commercial refrigeration system in regards to leak check reports. I have 2 different systems in my plant... an ammonia refrigeration system used for production and several self contained Mitsubishi units used for office cooling. Is the documentation requirement looking for the ammonia plant or the self contained Mitsubishi units?

The documentation should include all equipment that have more than 0.5 lbs of refrigerant and so I'm guessing it would include both the ammonia plan and the Mitsubishi units. In the case of ammonia, since its a natural refrigerant with an ODP and GWP of zero, it doesn't seem like leakage for that system will impact the credit calculation.
