Validation model for negative start time

Buildings.ThermalZones.EnergyPlus_24_2_0.Validation.RunPeriod.NegativeStartTime

Information

Validation model for negative start time. This test validates that EnergyPlus correctly simulates if it is started at a negative start time. The model simulates the last two days of the year and the first day. For comparison with the Modelica weather data, the model reads the solar irradiation and the outdoor drybulb temperature from EnergyPlus.

Extends from Examples.SingleFamilyHouse.Unconditioned (Example model with one unconditoned zone simulated in Modelica, and the other two unconditioned zones simulated in EnergyPlus).

Validation model for the start day of the week

Buildings.ThermalZones.EnergyPlus_24_2_0.Validation.RunPeriod.StartDayOfYear

Information

This validation case simulates two instances of Buildings.ThermalZones.EnergyPlus_24_2_0.Validation.OutputVariable.OneZoneOneOutputVariable, a model that outputs the electricity consumption that is specified via an EnergyPlus schedule. This schedule set the electricity consumption to zero for the whole day on Saturday and Sunday, but not on other days. In the instance sun, the start day of the year is left as the default, which is Sunday, and in the instance mon, it is set to Monday. Plotting the electricity consumption verifies that the setting is properly applied in EnergyPlus.
