Abstract: The authors developed a model that simulates task/ambient lighting and air-conditioning systems for office building. In the model, first, the stochastic mobility of office workers is simulated as the Markov Chain process. Then, the movement of the sensors used in the task/ambient systems to detect the location/movement of office workers is simulated. Then, the sensors’ information is converted to the operation of office equipment, lighting devices, air-conditioning and ventilation systems, and finally energy consumption is quantified. Thus, the whole model is capable of simulating heat and electricity demand of office buildings while taking into account the human mobility and the configuration and the operation strategy of sensor systems in addition to elements usually considered in the building performance simulation, such as geometry and insulation performance of the building. By using this model, the authors evaluated two types of sensor systems “infrared sensors” and “camera sensors” with different capability while assuming an office floor equipping task/ambient lighting and air-conditioning systems.
