Extends from Buildings.DHC.Loads.BaseClasses.PartialBuilding (Partial class for building model).

Information

This is a simplified one-zone building model based on EnergyPlus building envelope model. The heating and cooling loads are computed with a four-pipe fan coil unit model derived from Buildings.DHC.Loads.BaseClasses.PartialTerminalUnit and connected to the room model by means of fluid ports.
