"Why do outcomes differ between EnergyPlus simulations and manual calculations, despite using identical inputs, including equipment wattage and fraction-based usage schedules?
Note: When the fraction is continuous (e.g., 1), manual and energyplus have the same outcome. I used the schedule: compact for the fractional usage of equipment per hour. I thoroughly checked the inputs for both approaches but there is still a slight difference in their outputs. I am still a student so I please help me. Thank you!

This question will require some more specification. What calculations are your referring to? heating and cooling design loads, or simply internal gains over the course of a day, month, or year? How different are the results? are you using power density or absolute power? If using power density, there may be differences in the area due to wall thicknesses.
