Simulation and experiment study for optimizing the control of the heating/cooling source system of a green building

With the rapid development of green building, it is important to check the energy and environmental performance of the green building post occupation. This paper focuses on how to evaluate the energy performance of a green building's cooling/heating source of the air-conditioning system post occupation. The operation of the cooling/heating system is checked to find out the problems and optimal control strategy is proposed. The performance of proposed control strategy is verified by simulation and experiments. Simulation analysis confirms that the proposed control strategy can save 21.3% of the heating energy under the condition of satisfying the indoor temperature requirement. Experiments carried out in the building show that the experiment day's heating energy was saved by 19.5% compared to the comparison day, and the total electricity consumption of the cooling/heating source system was saved by 27.4%.
