Light + Building is the world's leading trade fair for lighting and building services technology, organised by Messe Frankfurt and held biennially at their Frankfurt venue. The event attracts over 200,000 visitors from across the globe and features thousands of exhibitors showcasing innovations in intelligent building systems, smart home technology, lighting design, energy management, electrical engineering, and building automation.
The fair's smart building and connected building tracks are directly relevant to smart city development, demonstrating how individual buildings can serve as intelligent nodes within broader urban technology networks. Key themes include building-integrated photovoltaics, AI-driven energy management systems, IoT sensor platforms for building operations, smart lighting that adapts to occupancy and daylight conditions, cybersecurity for connected building systems, and interoperability standards that enable buildings to communicate with urban infrastructure.
Light + Building's conference programme features presentations from architects, engineers, urban planners, and technology leaders exploring how intelligent buildings contribute to smart district and smart city objectives. Sessions examine how building data can be integrated into city-wide energy management platforms, how smart lighting infrastructure can serve dual purposes as environmental sensor networks, and how building automation standards can support broader urban interoperability goals.
The fair also hosts the Smart Building Innovation Award, recognising outstanding achievements in building technology that contribute to sustainable and connected urban environments. For professionals working in smart city development, Light + Building provides a comprehensive overview of the building-level technologies that form the foundation of intelligent urban infrastructure.
Frankfurt's role as a global centre for trade fairs and its concentration of smart building expertise make it the natural home for this essential gathering of the international building technology community.
