Tech Toolbox
Sustainable urban development today depends not only on the quantity of a city's "hard infrastructure"—such as roads, parks, landmarks, and transportation ("physical capital")—but increasingly on the availability and quality of communication, knowledge, and social infrastructure ("intellectual and social capital"). In this context, the implementation of digital solutions supported by locally generated data aims to deliver more efficient, innovative, and high-quality services and processes, for the benefit of all.
Specifically in the energy sector, increasing energy use represents a significant portion of a building’s operational costs and plays a key role in reducing these expenses, as well as in promoting a sustainable environment. For this reason, the EnerWise Tech-Toolbox incorporates a holistic approach to the management, processing, and analysis of energy data and additional information collected locally from each municipal or school building, by utilizing existing equipment and integrating new infrastructure where needed.
- Smart Energy Meters and Environmental Sensors
- They are installed at points of high consumption.
- They measure data such as energy consumption, voltage, current, power, frequency, etc.
- They measure ambient temperature and humidity data.
- They communicate using various protocols and transmit data to the cloud.
- Communication Gateway (ΙοΤ Middleware)
- Secure connection of all devices at a single point.
- Receiving data in real time
- Temporary data (buffering) and protocol conversion
- Data routing to databases, applications, and services.
- Central Data Storage and Processing Platform
- Storage of measurements with time stamps.
- Long-term storage of large volumes of data.
- Information about devices and their management.
- Consumption analysis, anomaly detection, energy optimization.
- Real-time charts and graphs.
- Notifications (alerts) and recommendations (guidelines) to support proactive measures.
- Reports on consumption and costing.
- Integration with third-party systems.
- Encryption (TLS/mTLS), device and user authentication.
- Access policies (RBAC), event logging, and monitoring.
In summary, the EnerWise Tech-Toolbox offers significant advantages that improve efficiency, reduce costs, and strengthen the energy strategy of the Municipality of Athens. Initially, it enables accurate and continuous real-time monitoring of energy consumption, providing a comprehensive view of the energy behavior of each device, installation, or department. Detailed data recording helps identify waste and supports the implementation of optimization measures, leading to substantial cost savings. Furthermore, through continuous data analysis, anomalies and overloads that could cause malfunctions are detected, allowing timely preventive maintenance and enhancing the safety of the respective systems.
