Background
85% of EU buildings were constructed before 2000, with 75% classified as energy-inefficient. The building sector accounts for 40% of Europe’s total energy consumption and 36% of greenhouse gas emissions (source: Energy Performance of Buildings Directive, EPBD).
These aging properties face three compounding challenges: they lack the real-time monitoring infrastructure needed to quantify thermal insulation performance or evaluate HVAC efficiency; HVAC and lighting systems run continuously in unoccupied rooms, causing significant energy leakage; and traditional automation retrofits require dedicated controllers for every room, making large-scale deployment financially unviable.
Solution
The team deployed the reComputer R1000 as the central intelligence of the system, building a closed-loop energy management architecture across four layers.
The R1000 serves a dual role: as a protocol converter, it unifies heterogeneous inputs from LoRaWAN, Modbus, BACnet, Wi-Fi, and 4G into a single data pipeline; as an edge logic engine, it processes data locally before forwarding lightweight MQTT/HTTP streams to the client’s Grafana-based dashboard.
The system operates across four layers:
- Sensing layer: LoRaWAN sensors monitor temperature, humidity, light intensity, CO₂, and smoke; smart meters track water, electricity, and gas consumption in real time; occupancy sensors detect room utilization and automatically trigger climate adjustments
- Connectivity layer: LoRaWAN reaches deep-indoor sensors, Modbus-RTU aggregates HVAC operational data, Wi-Fi integrates with lighting control systems, and 4G handles high-bandwidth backhaul to the cloud
- Processing layer: The R1000 performs data aggregation and control logic at the edge, eliminating dependency on cloud round-trips for real-time response
- Visualization layer: Edge-processed insights feed directly into a Grafana dashboard, delivering unified real-time energy monitoring across the entire building
Result
The R1000-based centralized edge computing architecture enables existing commercial buildings to achieve full energy data visibility and intelligent control — without overhauling their legacy infrastructure. The result is a meaningful reduction in carbon footprint and day-to-day operational costs, while maintaining peak building performance.
