The EPW file is hourly data. Is there a way to use 1-minuge interval weather data in EnergyPlus?

Yes. Most epw files are hourly, but the format can be used with shorter intervals. If you have a one-minute epw file EneryPlus can use it. You need to use the same interval for the simulation timesteps.

I have one month 1-minute interval weather data. I tried to insert those data into the existing EPW file. And the simulation failed.

I checked the EPW format documentation. To do the 1-minute interval weather data, we need to change the row 8 (DATA PERIODS, N2 to 60.)

That means we need to have the same interval across the EPW file.

And it also required the weather data interval to be the same as the time step.

        if ( NumIntervalsPerHour != 1 ) {
            if ( NumIntervalsPerHour != NumOfTimeStepInHour ) {
                ShowSevereError( RoutineName + "Number of intervals per hour on Weather file does not match specified number of Time Steps Per Hour" );
                ErrorsFound = true;
