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 these 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;
