BTC City Ljubljana is the largest business, shopping, entertainment, recreation and cultural centers in Slovenia. In a bid to reduce energy consumption and costs, BTC sought to implement an energy management (EM) system in line with the ISO 50001 standard. BTC turned to Solvera Lynx, the region’s leading provider of comprehensive energy management solutions, to monitor and reduce energy consumption.
To accomplish primary EM goals Solvera Lynx had wireless, long-range sensors utilizing LoRaWAN technology in mind. The idea was to connect and deploy this network of sensors and communication equipment throughout the entire BTC City, digitizing utility meters that could then send consumption data from all facilities to the GemaLogic software, where the data are gathered, processed and analyzed.
Deploying a network of indoor/outdoor sensors requires a special communication technology to overcome a variety of obstacles. LoRaWAN was a natural choice. To easily understand the benefits of LoRaWAN-enabled sensors, it is useful to compare it to WiFi, the commonly known indoor, wireless networking technology. Covering the wide area of BTC City would require dozens of WiFi access points, whereas only two LoRaWAN gateways were needed. With LoRaWAN, BTC City was able to set up its own private network within a week. Also, the battery life of LoRaWAN-powered sensors is much higher—5 to 8 years on average.
But the most exciting aspect was observing the small time intervals of sending data from normally inaccessible places. Once we connected the meters in the water shafts to the ComBox.L devices, we could receive data on water consumption every 15 minutes. Before, that was not possible, and water leakages were not detected.
