暖通空调（HVAC）是建筑能源管理系统（BEMS）的重要因素。为了保持能源效率和人体舒适度，需要对空调（AC）进行有效控制。然而，AC控制系统安装在建筑物中是昂贵的。在这项研究中，一个具有成本效益的空调控制系统，旨在为图书馆，它也适用于其他设施，如办公室和会议空间。该系统使用座椅传感器来保持能源效率和人体舒适度。传统的AC控制系统通常使用昂贵的运动传感器或视觉传感器以及温度和湿度传感器来获取关于用户的位置和舒适度的信息，并向用户提供基于位置的控制。为了降低基于传感器的成本，所提出的系统使用低成本的压力传感器，并保持能源效率和舒适度。为了检测座位占用率和位置，低成本的压力传感器和低功耗的通信节点连接到椅子上，它们将座位数据传输到服务器的数据库。一个可编程逻辑控制器是用来控制拟议的交流系统根据存储在数据库中的信息。在日本宫城县栗原市的一个图书馆进行了为期10天的实验，对该系统进行了评估。实验中的能源效率评估结果表明，该系统可以减少18.3%的电力消耗。通过测量预测的平均投票值的用户的图书馆，该系统被发现是能够保持用户的舒适度。
Heating, ventilation, and air conditioning (HVAC) are important factors for a building energy management system (BEMS). Efficient control of the air conditioning (AC) is required to maintain both energy efficiency and human comfort. However, AC control systems are expensive to install in buildings. In this study, a cost-effective AC control system intended for a library is proposed; it is also applicable to other facilities such as offices and meeting spaces. This system uses seating sensors for maintaining both energy efficiency and human comfort. Conventional AC control systems generally use expensive motion sensors or vision sensors as well as temperature and humidity sensors to acquire information on both the location and the comfort of users and to provide location-based control to users. In order to reduce sensor-based cost, the proposed system uses low-cost pressure sensors and maintains both energy efficiency and the comfort level. For detecting seat occupancy and locations, low-cost pressure sensors and low-power communication nodes are attached to chairs and they transmit seating data to the database of a server. A programmable logic controller is used to control the proposed AC system according to the information stored in the database. The system is evaluated using a 10-day experiment conducted at a library in Kurihara City in Miyagi prefecture of Japan. The results of energy efficiency evaluation in this experiment show that the proposed system can reduce electricity consumption by 18.3%. Through measurement of the predicted mean vote values of users of the library, the proposed system is found to be capable of maintaining user comfort.
