NC-v4 EAc6: Enhanced refrigerant management
For NC major renovation, when building is served by a campus central chilled water plant, does the central plant's refrigerant characteristics count towards the calculations required for this credit?

How can I determine the leakage rate of my equipment?
What is the required timeline for completing a CFC phase-out for this credit?
The refrigerant type I need to enter is missing from the credit form. What should I do?
Are HCFC or HFC refrigerants considered CFC-based refrigerants?

Hi Wes,
Yes, if you have a central plant, you will need to follow the guidance for upstream equipment. See the "Weighted Average Refrigerant Impact" example and "Project Type Variations" in this section of the Reference Guide. There are two options for demonstrating compliance:
- Show that both the upstream (central plant) and downstream (project building) equipment meets the requirements separately
- If that isn't the case, show that the requirements are met on a weighted average level, using only the portion of the central plant capacity serving the project building
Hope this helps!
