The idea proposed in this paper is to control the HVAC equipment with predicting the heating/cooling loads and indoor conditions by computational simulation according to the target, such as energy consumption, energy cost, CO2 generation and indoor thermal comfort. The simulation inputs is given by the measurement results, e.g. weather conditions, indoor temperature and humidity on the spot. The developed system controls HVAC system by using the real-time simulation, and investigates the performance of this system. The link and the data flow of the control cycle of the measurement, simulation and HVAC control were examined and demonstrated in the experiment.The result of the experiment for the cycle of the measurement, simulation and HVAC control is described. The experiment and simulation based on the prototype installed at the research facilities and on the virtual system for NIES building are shown as some examples. The former is a climate chamber as a typical and real size office including the heat source of the building. Simulation is carried out by TRNSYS and GAMS using the measured data and it shows the modified control method of HVAC system considering the results of TRNSYS simulation.
