NC-v4 EAc6: Enhanced refrigerant management
Hi
In Denmark our chillers are located at the roof, where there in the winter is a risk of freezing. The refrigerant in the cooling units are ammonia.
I have not been able to find any answers in LEED v4 manual, but should the liquid used for anti-freezing the pipes (30% glycol solution) be included in the calculation?
BR, Lise

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 Lise, in my experience it is not required to include glycol solution in the credit calculations, as it is considered an "antifreezer".
