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