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.
