The need for a more energy efficient future is now more evident than ever and has led to the continuous growth of sectors with greater potential for energy savings, such as smart buildings, energy consumption meters, etc. The large volume of energy related data produced is a huge advantage but, at the same time, it creates a new problem; The need to structure, organize and efficiently present this meaningful information. In this context, we present the ENCOVIZ platform, a multi-role, extensible, secure, energy consumption visualization platform with built-in analytics. ENCOVIZ has been built in accordance with the best visualisation practices, on top of open source technologies and includes (i) multi-role functionalities, (ii) the automated ingestion of energy consumption data and (iii) proper visualisations and information to support effective decision making both for energy providers and consumers.
