Abstract
Building Energy Management Systems(BEMS) are computer-based systems that help to manage, monitor, and control energy consuming facilities while providing comfort environment to occupants. To increase energy efficiency and maintain thermal comfort, simulation model based controls are developed and adopted rather than applying experiential know-how based controls. The simulation model consists of thermal load estimation and thermal dynamics calculation of Heating, Ventilation and Air Conditioning(HVAC) systems. The model is verified with measured data from BEMS installed in an existing office building. Error rates of simulation are 2.34% and 4.03% in terms of temperature and energy consumption of HVAC systems. This model was applied to finding optimal solution for energy saving control methods in the BEMS, and 14.4% of energy saving rate is measured in the existing building. This paper reports that the developed model represents thermal dynamics of building and is accurate enough to control HVAC systems of building.
