Heat Index vs. Heat Index OccupantHour vs. Heat Index OccupiedHour

Hi there,

For the parameters on Energyplus under the Annual Thermal Resilience Report. What is the difference between Heat Index, Heat Index OccupantHour, Heat Index OccupiedHour?

OccupantHour is the accumulated hours for the sum of all occupants in a space. But I'm slightly confused on the other two.

Thanks!

Does this help? It looks like it's hours, occupancy * hours, and occupancy when > 0 * hours. So total occupancy * hours and "occupied" occupancy * hours. But then why would that give a different answer for the last 2 reports?

ZoneHeatIndexHourBinsRepPeriod(ZoneNum, ReportPeriodIdx)[0] += state.dataGlobal->TimeStepZone;
ZoneHeatIndexOccuHourBinsRepPeriod(ZoneNum, ReportPeriodIdx)[0] +=
                                   NumOcc * state.dataGlobal->TimeStepZone;
ZoneHeatIndexOccupiedHourBinsRepPeriod(ZoneNum, ReportPeriodIdx)[0] +=
                                  (NumOcc > 0) * state.dataGlobal->TimeStepZone;
