An IoT-based integrated tool for testing energy consumption user awareness

An unaware behaviour of occupants can affect energy consumptions even more than installations and building envelope inefficiencies, with significant overconsump-tions widely documented. To reach an adequate awareness of energy consumptions, real time data and an effective and frequent billing of actual consumptions are required. From this point of view, the European Directive 2012/27/EU already imposed the use of me-tering and submetering systems, setting the minimum criteria for billing and related in-formation based on the real energy consumptions. To assess the ability of buildings to exploit new ICT technologies and sensitise both owners and occupants to related sav-ings, the new European Directive 2018/844/EU introduces a smart readiness indicator. In this paper the authors address the problem of gathering, processing and transmitting en-ergy consumption data in the framework of an IoT-based integrated tool aimed at in-creasing residential user awareness through the use of consumption and benchmark in-dexes. Two case-studies in which thermal and electrical energy monitoring systems have been tested are presented and discussed. Finally, the suitability of the communication of energy consumption in terms of temporal, spatial and typological aggregation has been evaluated.
