modelBuildingTimeSeriesWithETS
Model of a building with loads provided as time series, connected to an ETS for heating
Extends from BaseClasses.PartialBuildingWithETS (Partial model with ETS model for heating and partial building model).
Information
This model is composed of a direct controlled energy transfer station model for heating Buildings.DHC.ETS.Heating.Direct connected to a simplified building model Buildings.DHC.Loads.BaseClasses.BuildingTimeSeries where the space heating loads are provided as time series.
