However, to get a deeper insight into the company’s energy consumption, a new approach was needed. This involved detailed monitoring and data-driven analysis to identify the biggest energy consumers in day-to-day operations. What would it take? Reliable data, which the previous system could only provide at a macro level. So VistaMed’s team developed its own system for measuring power consumption, which could monitor not just a single machine, but the entire 42 – simultaneously and in real time. The cost of one monitoring unit was just 24.20 euros. Using these measuring devices, which can be bought off the shelf, the team developed a system that calculated and transmitted the power consumption of each connected machine every 15 minutes at the micro level: four measurements per hour, 96 per day, 672 per week. All measurement results were visualized in a dashboard that made it possible to perform a detailed analysis of energy consumption during peak and off-peak hours, and for each individual unit.
