User Assistance System for Smart Commercial Buildings – Use Cases and Proof of Concept

Abstract: Transferring existing buildings with their isolated and heterogeneous systems into the digital world is challenging. Consequently, this paper presents a novel User Assistant System for Smart Commercial Buildings. The demonstrated proof-of-concept on an existing building seamlessly integrates data from various building technologies and validates selected use cases. A wireless IoT sensor network enables the system’s services by collecting indoor climate data and tracking assets. Integrated Digital Twins for thermal predictions and modelling of photovoltaic systems (PVS) facilitate dynamic energy optimisation. The results show how to reduce subsystems’ operation hours and PVS payback time by providing intelligent, adaptable services.
