I am working on a hotel project that has multiple split system units. This means two part numbers, one for each unit, to account for all mechanical cooling equipment. In filling out the form for the EAc4 credit, there is no way of combining the two unit part numbers in a cooling system to account for the number of units, tons and refrigerant since they are broken apart in the form EAp3. Obviously, the two parts in a system share refrigerant so it does not make sense to enter the information twice as this would skew the impact per ton number.

Does anyone know how I document the split systems without double counting the refrigerants used? Should I combine the split system units on the EAp3 form? If so, will I use the outdoor condensing unit part number?
