I'm trying to control the charging of a thermal energy storage object in energyplus using EMS. I have it working pretty well based on the date, but I want the logic for whether or not to charge the tank to use the weather forecast for tomorrow, which in energyplus would mean consulting the weather file. However, EMS only seems to have access to weather data at the current time step and not at a future time.

Is there a way to access the outdoor air temperatures for tomorrow using EMS?

You could use a day ahead weather file schedule and access that schedule via EMS.

@rraustad I'm hoping for something more automatic. I have a measure that adds the ice storage tank, controlling objects, and EMS to the idf file. If the user needs to make a schedule of the hourly temperatures shifted by one day, that would severely reduce the advantage of automation.

I could write some code to parse the epw file and create the shifted weather schedule, but I'm really hoping there's an easier way.

I understand. That's the only suggestion I can think of at this time.
