EnergyPlus simulations are run at timesteps no shorter than an hour. HVAC equipment can have smaller timesteps, but generally, most of the components will use the timestep that you define in the SimulationControl object. The .eso and .sql file contain the output variables that you requested, and its size is a function of both the timestep and the number of variables requested.
If you first requested the variables to be yearly (RunPeriod), then changing them to hourly would give you an additional 8760 values. However, this should not be a problem if you are requestioning a single variable, such as the Facility Total Building Electric Demand Power. However, if you requested X variables, now you have X times 8760 results.
Check how many variables you are requesting, and delete any of them that you do not need for the time being. It will reduce your file size.

If you first requested the variables to be yearly (RunPeriod), then changing (RunPeriod) you would get a single reported value. Changing them to hourly would give you an additional instead 8760 values. However, this should not be a problem if you are requestioning requesting a single variable, such as the Facility Total Building Electric Demand Power.

HVAC equipment can have smaller timesteps, but generally, most of the components will use the timestep that you define in the SimulationControl object. The .eso and .sql file contain the output variables that you requested, and its size is a function of both the timestep frequency and the number of variables requested.
