I want to optimize the hourly temperature thermostat setpoints of an EnergyPlus idf model given a price of electricity at each hour. In other words, the goal is to minimize the cost of electricity by adjusting the setpoint temperatures at each hour.

Is this possible using GenOpt or something like that? I've been looking into GenOpt but can't seem to do optimization of hourly variables.

@cmm what are you trying to optimize? It sounds like minimum annual or peak energy cost. Also, are you looking to optimize the hourly temperature setpoints of thermostats in zones or supply air/water temperatures supplied by central systems?

Yes, minimum energy cost. The variables would be the hourly setpoint temperature of the thermostats in the zones. In my case, same temperature setpoint for all zones of a single story residential house but varies by hour.

If you set up the set point schedule in the EnergyPlus idf file as an EnergyPlus schedule, you can override each set point value from GenOpt.
