NLB Bank, through the acquisition of Komercijalna Banka, has become one of the leading banks in the region with a large network of branches. ION Solutions automated the central building of NLB Komercijalna Banka in New Belgrade, over 140 branches across Serbia, and the bank's central building in Podgorica, Montenegro.

In the central building in New Belgrade, integrated systems include fan coil units, window open detection, DALI controllers for lighting, motion sensors for lighting and HVAC control, as well as motorized curtain control through HDL multifunctional panels. If a window in any zone is opened, the system automatically shuts off the HVAC for that zone. After working hours, the system activates all blinds (lowering them in summer and raising them in winter) to reduce air conditioning costs, turns off all lighting, switches the HVAC system to standby mode, and signals the positions of open windows on the central software. Before working hours, the system prepares the workspace by regulating temperature through fan coils and blinds. All system elements can be controlled via computer and mobile application, with user administration featuring different access rights.

Additionally, the building integrates a Schneider Electric BMS system that integrates mechanical and electrical systems. The system monitors and controls 4 air handling units, ventilation, heating substations, fire dampers, electrical distribution, and consumption, as well as the fire protection system.

In 140 branches of NLB Komercijalna Banka, a BMS system has also been implemented that monitors electricity consumption and manages boilers, heating systems, and illuminated signs.
