Light + Building 2024 showcases naturally sustainable energy

Photovoltaic systems (PV systems) have a central role to play in providing sustainable energy for the future. From private balcony power plants to systems on the roofs of apartment buildings and commercial photovoltaic fields, subsidy programmes and legal simplifications are designed to accelerate the expansion of Europe’s energy systems. Thus, as aspects of building-services technology, PV systems, energy storage and control, as well as systems integration, are set to gain in significance at the coming Light + Building from 3 to 8 March 2024.

At Light + Building, the world’s leading trade fair for lighting and building-services technology, over 2,000 national and international manufacturers are getting ready to present both intelligent lighting systems and future-oriented home and building-services technology. The electrical infrastructure is a prerequisite for convenient home and building automation, efficient energy storage and management, the connection of PV systems and charging stations, as well as electrical heating systems.

“Trade fairs mirror markets. And Light + Building directly reflects the latest developments in the sector. In the field of building-services technology, the subjects of the source, independence and storage of energy have become increasingly important over recent years. Accordingly, these topics are also growing in significance at Light + Building with the number of exhibitors showing such products and services increasing and new companies discovering the world’s leading trade fair for themselves,” says Johannes Möller, Director Brand Management Light + Building.   

Solutions for increasingly important subjects, such as PV systems and energy storage, dominate Halls 11 and 12. 70 of the exhibitors there are experts for the subjects of e‑mobility and charging infrastructure while 45 companies present innovations and products for decentralised energy-supply systems and components. Ten of them are specialists for photovoltaic systems. The key players in Halls 11 and 12 include ABB, ABL, Amperfied, Bosch Thermotechnik, Compleo Charging Solutions, Fronius, Go-e, Hager, Hensel, Hepa Solar, Legrand, Mennekes, OBO Bettermann, Phoenix Contact, Schneider Electric, Siemens, SMA, Senec, Spelsberg, Walther-Werke, Weidmüller and Wieland.

With electrical engineering, home and building automation and connected safety and security technology (Intersec Building), the world of building-services technology is also to be found in Hall 9.

Knowledge transfer & networking: events spotlighting regenerative energies

The Building Plaza in Hall 9.0 is the meeting place for knowledge transfer, events and inspiration in the field of building-services technology. On Tuesday, 5 March 2024, the programme revolves around the subject of regenerative energies with numerous lectures and panel discussions being held under the motto ‘Storing and managing energy’. The programme continues on Wednesday and Thursday, 6 and 7 March 2024, with the first ‘Building in the Energy Transition’ congress. Under the heading ‘Light up the Future: Innovations for a sustainable energy supply in buildings and districts’, visitors can look forward to lectures, panel discussions and tours of the fair offering insights into the latest research from the field of sustainable energy supplies for buildings.

Light + Building – the world’s leading trade fair for lighting and building-services technology. The next Light + Building opens its doors from 3 to 8 March 2024.
