Hi all, 

Can we include the capacity of the cooling towers in the weighted average calculation? This will cover most of the cooling in our building. However we do need to include some smaller units in certain rooms. There is no availability of low gwp units such as smaller split-units with the trusted suppliers. 

If we only take the small units into account, we will not be able to meet the theshold of the calculation eventhough the mainsystem does meet the credit(intention). 

Does anyone have experience with this?

Best regards,
