Abstract: Provided is a building equipment energy control system, the system including: a library configured to receive information on an equipment unit from a DDC device controlling a plurality of equipment units installed in a building, and store the received information; a modeling module configured to retrieve information on the equipment unit from the library and perform simulation modeling for the equipment unit to calculate energy usage; a control module configured to generate a control command for the equipment unit based on the energy usage calculated by the modeling module and provide the control command to the DDC device; and a correction module configured to calculate an error rate between actual energy usage of the equipment unit and the calculated energy usage and correct information on the equipment unit. Therefore, it is possible to derive an optimized control set value for each equipment unit by performing simulation modeling for various equipment units, so that energy saving performance and operating efficiency of the equipment units can be increased. In addition, by providing equipment performance information and equipment operation information for each equipment unit to a library in a modeling process, it is possible to optimize a control according to product specifications and operating characteristics of each equipment unit.
