Development of a Multi-Point, Multi-Layered Observation System for Indoor Thermal Environment Using IoT Devices

Abstract

With the introduction of air conditioning systems in schools, interest in indoor thermal environment has increased. The Academic Standard for Measurement Methods of Indoor Thermal Environment established by the Environmental Engineering Committee and the Thermal Environment Subcommittee of the Architectural Institute of Japan ‹AIJ › defines the target range of indoor thermal environment for occupants as the living area, and the measurement position is basically at the center of the space. However, in the case of a classroom, a single central observation point is considered insufficient because many students are present in the entire classroom. Therefore, in this study, we developed and tested a prototype system that uses IoT devices to observe the temperature and humidity in a classroom at multiple points and in multiple layers, in order to understand the thermal environment in detail. As a result, it was found that the system can be used as an alternative to conventional observation methods.
