In this study, occupant information, one of the information that can be found in the operation stage of the building, was collected using an actual survey. After converting occupancy data to HVAC system operation schedule, it was analyzed and compared the change of energy consumption applied with occupancy-based HVAC control. As a result, the actual number of occupants was smaller than the case where the occupancy density per area was set, so the energy consumption of the total building decreased by 15.16%, and the energy consumption of the HVAC system decreased by 34.32%. When the occupanct-based HVAC control was applied, the energy consumption of the entire building decreased by 9.71%, and the energy consumption of the HVAC system decreased by 28.42%. As a result of analyzing energy consumption by system, the control of occupancy-based HVAC control has a greater energy saving effect on heating than cooling. The occupancy-based HVAC control is simpler than other controls and has a significant energy saving effect. |
