Uma estratégia de retrofit para monitoramento energético em sistemas prediais legados

Electric energy management enables the planning and efficient use of this input to improve competitiveness, sustainability and reduce costs for the final consumer. Along with this, the Internet of Things (IoT) paradigm promotes the emergence of solutions for remote energy monitoring, in order to enable strategies for this type of management. However, most of these solutions favor the disposal or replacement of outdated but still necessary elements. Thus, a strategy that allows the retrofit of legacy building systems to implement monitoring resources that help in energy management is necessary. In this sense, this work presents a strategy to enable energy monitoring in legacy building infrastructures using retrofit techniques. To validate the proposal, we developed embedded platforms for monitoring building electrical circuits in a power distribution board and developed a software application to integrate these devices and visualize the acquired data. The results present an alternative to improve energy management through remote monitoring and the maximum use of pre-existing resources.
