EnergyPlus schedules and daylight savings time
EnergyPlus automatically interprets schedules as being in local time, and therefore shifting with daylight savings time. This is usually the correct occupant-driven behavior. However, there are situations when it would be more natural to input a schedule in standard time. For example, the California TDV (or any other time series schedule derived from grid interactions) is more naturally expressed as a basic standard-time time series. Might EnergyPlus add a new flag or Schedule object to allow for this kind of input? Alternatively, OpenStudio could (or maybe already does?) support this modeler-friendly feature.

My understanding is that E+ applies daylight saving time when either of these conditions are met a) if epw file has
Daylight Saving Start DateandDaylight Saving End Datein the lineHOLIDAYS/DAYLIGHT SAVINGSand input fieldUse Weather File Daylight Saving PeriodinRunPeriodobject in idf is set toYesb) Or epw may not have daylight saving period but idf hasRunPeriodControl:DaylightSavingTimeobject.
