How to Model a Cold Water Booster Pump for Service Hot Water Demand?

I am modeling a fairly tall building with a booster pump that supplies pressured cold water to the building and make-up water to the water heater. I realized that the booster pump in the design could be a pretty significant load on the building but I couldn't find a way to model the cold side of a domestic hot water loop.

Is there a component in OpenStudio or EnergyPlus that represent the supply of cold water to the building that would capture the energy consumption of the booster pump?

There's no object that does that in EnergyPlus (in any BEM tool that I know personally actually).

You'll have to model it as an ElectricEquipment and do a side calculation to set its design power consumption and schedule.
