Information

This example validates Buildings.DHC.Loads.BaseClasses.SimpleRoomODE by comparison with Buildings.ThermalZones.ReducedOrder.RC.TwoElements.

A first instance of the reduced order model is used to assess the heating and cooling loads. A second instance is used to assess the indoor air temperature variation when the rate at which heating or cooling is provided is lower than the load. That second instance is used as a reference for the validation.

Eventually the validation is performed with two sets of ambient conditions, one requiring heating, and the second requiring cooling.
