Intelligent lighting control
with LOYTEC solutions
HQ Regione Emilia Romagna.
Designed by Kenzo Tange in the 1970s, the iconic Fiera District Towers were conceived as part of a visionary plan to modernize and expand Bologna. Inspired by the city’s medieval towers, the complex has become a landmark of contemporary architecture and a key business and exhibition hub for the Emilia-Romagna region in Italy.
As part of the retrofit project at the Emilia-Romagna Regional Headquarters, our Competence Partner, Casadei & Pellizzaro, delivered an advanced Building Management System (BMS) designed to enable intelligent control of the building’s entire lighting infrastructure. The existing system was based on the LonMark protocol and supported by a robust IP network. However, in light of the gradual decline in LonWorks technology adoption, a modernization was required.
The system was therefore upgraded to the BACnet protocol, now widely recognized as the industry standard for integrating BMS solutions over IP networks. The building extends across 11 floors and includes 2,500 lighting fixtures. The project introduced innovative automation strategies capable of dynamically adjusting lighting conditions based on space usage, occupant presence, and the availability of natural daylight.
THE CHALLENGES
Upgrade an outdated system by transitioning from LonWorks to a more modern and widely adopted protocol such as BACnet/IP.
Enable intelligent management of a large-scale lighting system, automatically adapting it to occupancy levels and natural dayligt
Deliver a flexible lighting system with DALI-2, improving efficiency, comfort, and maintenance.

The Solution.
LOYTEC delivered a comprehensive lighting control solution based on DALI-2 and BACnet/IP, ensuring long-term scalability, flexibility, and sustainability. Each floor of the building, with the exception of certain special floors such as the ground floor with the reception area, consists of 28 offices: 14 on the East wing and 14 on the West wing, in addition to the corridors and the areas adjacent to the elevators.
The customer requested the possibility of using a dedicated controller for the two wings, EAST and WEST, to provide greater flexibility during maintenance operations.
Lighting Controllers:
Two LDALI-ME202-U DALI controllers with integrated power supply were installed on each floor, one serving the east wing and one the west wing. In total, 22 DALI-2 controllers were deployed across the entire building, enabling independent management of the different zones.
Sensors and Local Control:
To support advanced automation strategies, 254 multisensors (LDALI-MS4-BT) were installed for occupancy detection and light level measurement, enabling constant light control.
Additionally, 254 push-button interfaces (LDALI-BM2) were integrated to allow users to locally control the lighting.
Centralized BMS Platform:
To provide a unified management interface and streamline operations, the LOYTEC LWEB-900 software platform was implemented.
This enables monitoring and control of all floors and their respective lighting areas.
Benefits.
The implemented solution delivers a wide range of benefits in terms of energy efficiency, occupant comfort, operational flexibility, and overall system management.
The modernization not only reduces energy consumption and operating costs, but also enhances the user experience through adaptive lighting strategies while providing a scalable foundation for future upgrades and integrations. In addition, the new architecture simplifies maintenance activities and improves long-term reliability, ensuring the building remains efficient, sustainable, and ready for evolving operational requirements.
Energy Efficiency
Control strategies based on actual occupancy status and the use of natural light significantly reduce the energy consumption of the 2,500 lighting fixtures.
Occupant Comfort
Adaptive lighting based on occupancy, daylight availability, and environmental conditions can improve visual comfort, support well-being, and contribute to a more productive indoor environment.
Flexibility and Future Integration
The use of BACnet/IP and DALI-2 standards ensures compatibility with future systems and simplifies integration with other building technologies.
Optimized Maintenance
The architecture, featuring dedicated controllers for each wing, allows localized interventions and minimizes operational impact during maintenance activities.
Ease of Use
The LOYTEC LWEB-900 platform provides an intuitive interface for facility managers and maintenance staff, enabling real-time monitoring, alarm management, and centralized operational control.
Transparency and Scalability
The system ensures full visibility of all installations and can be easily expanded or adapted to meet evolving requirements.
Conclusion.
The lighting refurbishment project at the Emilia-Romagna Regional Headquarters stands as a concrete example of how modern BMS technologies can significantly enhance building performance. By leveraging LOYTEC solutions based on DALI-2 and BACnet/IP, it was possible to replace an outdated infrastructure with an intelligent, open, and future-ready system.
The result is a highly efficient and flexible environment designed around occupant comfort, capable of optimizing energy consumption while simplifying operational management. This project sets a strong example for large public-sector modernization programs, demonstrating how open standards and integrated solutions can support the development of smarter buildings.
