Can we model the thermal energy storage with electric chiller in OS. I have gone through the questions in unmet hours and couldn't get clear idea whether it can be done with OpenStudio alone or have to model in EP.

I want to model with 1 Chiller, 4 AHU, 2 Ciculation pump and 1 Thermal energy storage tank. The analysis shall be done for peak load demand offset. The sample diagram of OS model(screen shot) with set point manager details will be very helpful for me.

Thanks
