Extends from Buildings.Air.Systems.SingleZone.VAV.Examples.OptimalStart.ConventionalSpring (Example model using the block OptimalStart with a conventional controller for a single-zone VAV system in spring).

Information

This is an example model on how to use the block Buildings.Controls.OBC.Utilities.OptimalStart that integrates with a conventional controller, a single-zone VAV system and a single-zone floor building. The building, HVAC system and controller model can be found in the base class Buildings.Air.Systems.SingleZone.VAV.Examples.OptimalStart.BaseClasses.ZoneWithAHUConventional.

This example validates the optimal start results for the summer condition. Note that the optimal start block in this example computes for both heating and cooling conditions. The first few days are initialization period. The optimal start block calculates the optimal precooling time based on the moving average temperature slope of the zone computed from previous days.
