User role in IoT-based systems

Currently, in the paradigm of the Internet of Things (IoT) there is a novel strategy to experiment from the human centric perspective whereby the users are the owners of the rules operating smart things. As members of an IoT ecosystem, users inform about their needs and desires, and provide feedback within a networked intelligence to jointly improve their individual ability to rule the actuators of the system at their service. In this paper, we propose an example of a user-centric IoT system in the smart buildings field, in which energy saving is achieved because users behavior aspects are considered for the management of the buildings' infrastructures. An important aim of our user-centric building management system is to bring user role in the loop of the operation system. This platform has been deployed in an office which is a real case of smart building. Experimental tests have been carried out to assess the energy saving derived from considering a user-centric management. The first experimental stages of this system already reflect energy saving of about 23.12% respect with the energy consumption associated to previous periods with similar context conditions.
