Indoor air quality monitoring in the office building

Abstract

The aspect of indoor air quality has found special recognition in the current EU Directive on the energy performance of buildings (EPBD (2024/1275/EU), Article 13). It identifies a system for monitoring and regulating the parameters that contribute to indoor air quality as a key technical solution necessary to achieve and maintain adequate indoor air quality. It specifies that building automation and control systems must enable the monitoring of indoor environmental quality by 29 May 2026 at the latest. Air quality analysers based on radio technology enabling Internet connectivity (IoT) are a minimally invasive alternative to classic cable systems in this respect. Thanks to this functionality, they enable a significant reduction in the costs associated with equipping buildings with air quality monitoring and control systems. For this reason, meters with smart sensors based on IoT technology were deliberately used to measure air quality in a sample non-residential office and service building. The devices were selected based on an analysis of technical data provided by the manufacturer. The aim of this article is to further the particularly topical discussion on the role of indoor air quality monitoring in promoting a healthy, energy-efficient and productive 
indoor environment by presenting an example of good practice in this area. It reviews scientific literature on the relationship between indoor air quality and ventilation, with an emphasis on the negative effects of poor air quality. The article presents sample results of indoor air quality measurements carried out in an office room, which are only a small part of the air quality analysis presented.
