Abstract Detailed occupancy information in buildings is useful to improve the performance of energy management systems in order to enable energy consumption savings and maintain occupants' comfort. Different technologies employed to provide occupancy information account for high-precision devices such as optical and thermal cameras, and environmental or specialized sensors like carbon dioxide (CO2) and passive infrared (PIR). Although the latter systems have lower accuracy, they have received significant interest due to their affordable and less-intrusive nature. Accordingly, various studies have been conducted to explore the various elements of these technologies. Nevertheless, the algorithmic aspect of the occupancy detection process has not been adequately taken into consideration. This paper presents an extensive review of the techniques that have been exploited to process the information provided by the sensors and carry out occupancy information detection. In this study, a complete set of comparison criteria, comprising the performance, the occupancy resolution, the type of sensors used, the type of buildings, and the energy saving potentials has been considered in order to perform an in-depth analysis of the occupancy detection systems. Through its examination, this paper elaborates significant remarks on occupancy detection algorithms in order to realize a method that is not only efficient in processing sensors’ data but also effective in providing accurate occupancy information.

对建筑物占用检测方法的全面审查

摘要 建筑物中详细的占用信息有助于提高能源管理系统的性能，以实现节能和保持居住者的舒适度。用于提供占用信息的不同技术适用于高精度设备，例如光学和热像仪，以及环境或专用传感器，例如二氧化碳 (CO2) 和被动红外 (PIR)。尽管后一种系统的准确性较低，但由于其价格合理且侵入性较小，因此引起了人们极大的兴趣。因此，已经进行了各种研究以探索这些技术的各种要素。然而，占用检测过程的算法方面还没有得到充分考虑。本文对用于处理传感器提供的信息并进行占用信息检测的技术进行了广泛的回顾。在本研究中，考虑了一套完整的比较标准，包括性能、占用分辨率、使用的传感器类型、建筑物类型和节能潜力，以便对占用进行深入分析。检测系统。通过检查，本文详细阐述了占用检测算法的重要意义，以实现一种不仅有效处理传感器数据而且有效提供准确占用信息的方法。考虑了一套完整的比较标准，包括性能、占用分辨率、使用的传感器类型、建筑物类型和节能潜力，以便对占用检测系统进行深入分析。通过检查，本文详细阐述了占用检测算法的重要意义，以实现一种不仅有效处理传感器数据而且有效提供准确占用信息的方法。考虑了一套完整的比较标准，包括性能、占用分辨率、使用的传感器类型、建筑物类型和节能潜力，以便对占用检测系统进行深入分析。通过检查，本文详细阐述了占用检测算法的重要意义，以实现一种不仅有效处理传感器数据而且有效提供准确占用信息的方法。
