Greetings, I am a user of Trace 3D+ and they currently do not have central (or system level) heat pumps in the equipment library. I am finding that I often need to model a heat pump in a DOAS.

Does open studio or energy plus have central (or system level) water to water, water to air, and air to air heat pumps that can be selected from a library of equipment?

How about system level ERVs (energy recovery ventilators) with reheat capabilities? Best, Greg Estep
