There's a tool called the Building America Domestic Hot Water Event Schedule Generator (BA DHWESG) that can be used to generate a full year of discrete hot water events. You can set the interval you'd like your data at and each draw has an end use associated with it. You can find the DHWESG here: https://www.energy.gov/eere/buildings/building-america-analysis-spreadsheets, and if you're interested in the background on how the tool works there's a paper on it here: https://www.nrel.gov/docs/fy10osti/47685.pdf.To use the results from the DHWESG in EnergyPlus you can add Schedule:File and WaterUse:Equipment objects to set the hot water draw.
