Sažetak
The improvement of life quality and the work environment arise the need for innovations in predicting real-time thermal comfort that consequently benefits to occupants’ well-being and productivity along with the more rational use of energy in the building. The discrepancy between energy usage and office thermal comfort highlights the call for reliable control mechanisms. One way to mitigate excessively dissipation of energy is to re-evaluate what actually makes occupants comfortable focusing on their individualism. Human parameters such as the metabolic equivalent of task (MET) and occupant’s activity level are unfairly and improperly reduced on simple activity diary method in BS EN ISO and ANSI/ASHRAE Standards. In this paper, the occupants’ role is recognized as double, a sensor and an indicator of preferences. Therefore, the biosensors are deployed to provide real-time MET information during the heating season, together with the sensors for collecting the environmental conditions such as air temperature, relative humidity and a level of carbon dioxide (CO2). Moreover, a survey questionnaire is used to evaluate occupants’ thermal comfort. All measurements were conducted in-situ. In total, eight subjects participated in the investigation. The conclusions of this study can be useful to set possible standards for regulation of the air- conditioning systems in office buildings as well as operating parameters for achieving an indoor environment that is most preferred.
