SOLUTIONS THAT SCALE GLOBAL ASSOCIATES USES RENESAS SMARTSERVER™ IOT TO INTEGRATE LoRaWAN ® AND BMS FOR POWERFUL ON-PREMISES DATA ACCESS AND CONTROL LoRaWAN ® IS THE RIGHT LPWAN For retailer client DFS, global associates needed a solution that would monitor a wide array of conditions at each of DFS' 170 sites including environmental (CO2 , humidity, temperature), occupancy (motion detection), metering and load control (voltage, current, power, and energy), heat exchanger maintenance (vibration). LoRaWAN was the right LPWAN to deploy because of the diversity of LoRaWAN sensor types, its 10km line of sight signal, and 10-year battery life. LoRaWAN ® SCALES The LoRaWAN deployment collects and processes 700+ different datapoints at each DFS site, updating every minute. It can be further scaled for evolving requirements, such as additional sites or sensors for new applications. The Renesas SmartServer™ IoT solution is easily replicated and accelerates rollouts, saving precious engineering time and cost. SITUATION global associates, a master systems integrator, was engaged by DFS, a retailer, to help in its drive toward carbon neutrality. global's remit was to significantly reduce overall energy usage by implementing energy efficient controls across DFS' 170 sites including retail stores, offices, factories, and warehouses. The initial target was to reduce energy usage by 10% with fast ROI – demonstrating tangible results within one year. ISSUE global's approach was to feed LoRaWAN sensor data into the existing BMS to enable intelligent, on-premises control. However, LoRaWAN sensor outputs weren't directly compatible with DFS' BMS. global also had to integrate myriad other sensors and devices from the existing infrastructure including BACnet, Modbus, LON and various RS-485 connections plus LoRaWAN sensors and actuators for HVAC and lighting. global wasn't aware of a holistic solution that could provide this capability, so they began their own internal development. That effort became resource intensive; they needed a commercially supported solution that was ready to implement with no delay. Buildings Europe Device Maker Contact:
