The modernisation of existing non-residential buildings in Germany continues to be sluggish, as evidenced by the renovation rates of recent years. At 0.92 per cent in 2025 (compared to 0.95 per cent in 2024), the energy-related renovation rate remains well below the targeted goals. This shifts the focus to efficient and minimally invasive measures that can be implemented quickly and achieve significant improvements. Lighting systems represent an effective starting point here, as their modernisation can often be realised without extensive structural changes or prolonged operational interruptions.
Beyond measurable energy savings, contemporary lighting also unlocks potential for increasing light quality at the workplace. Daniel Ludwig, Head of Sales KAM EGH at LEDVANCE, notes that renovations in daily operations rarely fail due to a lack of willingness, but primarily due to complexity and insufficient time resources. Accordingly, solutions are needed that quickly take effect in existing buildings without requiring comprehensive interventions. Lighting, in this context, is a particularly relevant measure, as it can be modernised quickly, immediately improves efficiency and maintenance effort, and lays a reliable foundation for future, economical building operations through integrated sensor technology and control.
With technological solutions, existing installations can be converted to modern LED technology without significant additional effort. This leads to energy savings, simplifies maintenance, and contributes to increased planning certainty. An example is the "Panel Surface", which was designed for ceiling surface-mounted renovations. It is mounted directly, allowing ceilings to be renovated without interfering with the building structure. The system is suitable for offices, corridors, and various commercial properties. It replaces existing T5/T8 grid luminaires, conceals visual irregularities, and creates a homogeneous appearance. Available in three sizes (674 mm, 1274 mm, 1574 mm) and different versions, for instance with integrated sensor technology or DALI control, it offers flexible application possibilities.
- —No dismantling of the existing luminaire is required.
- —Quick one-person installation due to integrated connection box.
- —Flexibly selectable lumen packages and colour temperatures (3000 K / 4000 K).
- —High efficiency up to 130 lm/W with up to 6,240 lm.
Another option is the "Floor Standing Compact" floor lamp. This minimalist-designed luminaire features an integrated sensor and can be directly connected and used without fixed installation. Available in three housing colours (white, grey, black), it is particularly suitable for use in individual and open-plan offices. It enables lighting modernisation without reconstruction and offers integrated sensor technology for automatic energy saving as well as high light quality for screen workplaces with 4000 K. Powerful with up to 144 lm/W and 12,600 lm total luminous flux, it represents a flexible all-in-one solution.
For more demanding environments, such as warehouses, workshops, or car parks, the robust moisture-proof luminaire "Damp Proof Fit" is designed. This allows for uncomplicated renewal of existing lighting systems. Thanks to flexible multi-select functions for luminous flux and colour temperature, tool-free installation, and a high degree of protection, this solution is suitable for industrial applications. The high efficiency of up to 160 lm/W and the robust IP65 housing ensure operational reliability and longevity. The availability in three lengths (600 mm, 1200 mm, and 1500 mm) underlines the flexibility of its application in the respective context.
