Hello,

As you know, the LEED online Letter template requires us to input the Manufacturer Name and Model Number of the refrigeration systems being used on the project

The issue we're facing is that the exact models have not been chosen yet. They will be selected and purchased by the contractor based on the performance specifications. The M&E have already specified the max Refrigerant Charges allowed and the fact that CFCs are prohibited.

Knowing that this is a design credit, can I upload the excerpt of specs showing the max Refrigerant Charges and the non-CFC requirement ? Or should I wait till the contractor chooses the models (which is at construction phase)

Thanks for help,
