Lighting refurbishment
#1: Save on electricity and electricity bills
Closing the energy-saving gap
Reducing electricity consumption saves money, cuts CO₂ emissions and helps bridge the energy gap in winter.
Options for lighting refurbishment:
Retrofit bulbs
Simply replacing fluorescent lamps with LED retrofit or conversion lamps results in a reduction in visual comfort, often fails to meet the requirements of health and safety legislation, and can also cause problems (limitations on dimming, safety risks associated with certification marks, inappropriate light distribution, etc.)
One-for-one exchange
The energy consumption of each individual light fitting is significantly reduced by replacing existing fittings with new LED ones or by retrofitting them with conversion kits in a resource-efficient manner.
Complete LED refurbishment
The switch from fluorescent lamps to LED solutions is often accompanied by changes in illuminance and light distribution. Professional lighting design and the resulting positioning of the luminaires make the most of additional opportunities for energy savings.
Complete LED refurbishment with lighting control
By incorporating motion and/or daylight sensors, the time the lights are switched on is reduced. A lighting control system allows the full potential for savings to be realised.
#2: Reduce investment
Attractive funding schemes make upgrading your lighting particularly appealing at the moment and help keep investment costs low. However, there are also financing models that allow you to upgrade your lighting without any upfront investment. To this end, Zumtobel offers the ‘Rent lighting instead of buying’ service.
Practical tips for your funding:
- As sensor technology and lighting management offer significant potential for savings, their use is often subject to additional incentives.
- For your refurbishment project, use only DALI-dimmable LED luminaires.
- In many cases, a simple 1-for-1 replacement does not meet current lighting standards. It is better to opt for a complete refurbishment with lighting design in accordance with EN 12464.
- To qualify for a grant, minimum energy performance indicators (calculated in accordance with SIA Standard 387/4) and maximum illuminance levels (max. 20% above the standard value) must be met.
- Apply for the grant as early as possible and, in any case, before the project is implemented. You can submit further details at a later date.
- Funding schemes cannot be combined.
- Funding grants are paid exclusively to the building owner.
- The schemes support a maximum investment of CHF 300,000 per building owner. If your investment costs are higher, you can submit a project application.
- The useful life of the lighting system is set at 15 years. The payback period must be more than 4 years.

#3: Harnessing lighting management to achieve savings
-50% on electricity costs: a one-to-one replacement with LED lights
LEDs are twice as efficient as fluorescent lamps and up to 10 times more efficient than halogen lamps. Given the wide range of options offered by LED technology and the globalised market, choosing the right product can seem somewhat more challenging. Zumtobel not only offers the latest technologies and energy-efficient luminaires for every application, but also expert advisors who provide lighting consultancy to customers throughout Switzerland.
-70% on electricity costs: LED lights with presence and daylight sensors
The Zumtobel portfolio includes a range of sensors that act as a link between artificial and natural light. Combined with an intelligent lighting control system, they ensure that the right amount of light is available at all times. Or that the lights are switched off when they are not needed. In particular, the combination of presence detection and daylight control can significantly reduce electricity costs. Furthermore, the right amount of light also plays a key role in people’s concentration and well-being.
-80% on electricity costs: LED lights with lighting control and professional lighting design
With professional planning and commissioning, a lighting system can realise its full potential. When positioned correctly, the number of luminaires can often be significantly reduced. Professional commissioning at the outset also ensures that all components of a lighting solution are optimally coordinated. Zumtobel’s lighting experts are on hand to provide expertise and tailored services at every stage.
Methods for refurbishment
Replace: Replace lights on a one-for-one basis
If you wish to retain the existing lighting design, we recommend a one-for-one replacement of the luminaires. Each luminaire in the system is replaced with a new LED luminaire – without any changes to the existing installation. Modern replacement luminaires improve light quality whilst reducing energy and maintenance costs.

Refurb: Retrofitting luminaires with LED conversion kits
If the existing luminaires are of high quality and in good condition, it makes sense to upgrade the technical components in a way that conserves resources. This can be achieved using standardised retrofit kits or bespoke solutions. This allows for a significant reduction in energy consumption and maintenance costs – whilst maintaining or even improving the quality of light.

Reuse: Refit the light strip rails
Where long-lasting continuous lighting systems such as TECTON are in use, the existing infrastructure can continue to be utilised. The existing busbars are simply fitted with new LED modules – a quick and resource-efficient process. On the flexible TECTON track, each luminaire can be freely positioned and precisely aligned to meet specific requirements. Sensors or emergency lighting modules can also be integrated.

Replan: Redesigning the lighting
If the way the space is used, its layout, or the requirements regarding light quality, efficiency and digitalisation have changed significantly, a complete redesign of the lighting is recommended. This involves developing a new lighting concept – including the layout, luminaires and control system. With professional planning, a lighting system can realise its full potential – through the effective use of every single luminaire.

Applications
Industry
Upgrading lighting in industrial settings is worthwhile for a number of reasons. We have summarised all the benefits for you – including practical tips and recommendations from our product range.
Office
A pleasant, motivating working environment, glare-free visibility of the screen and reduced energy costs are the benefits of modern office lighting. With Zumtobel products, you also gain a flexible lighting solution that can be easily adapted to human needs, architectural conditions and new ways of working.
School classes
Learning guides rather than teachers. Freedom rather than coercion. The new learning concepts no longer fit the standard mould of the past. Innovative teaching methods place greater demands – including on lighting. Many schools are recognising this need and carrying out refurbishments. Zumtobel’s lighting portfolio offers a wealth of options to meet diverse needs and accommodate architectural and budgetary constraints.
Shop
Modern, high-quality retail lighting does more than simply create shopping experiences and showcase products in the best possible light. By harnessing the emotional impact of light, lighting concepts can be developed that perfectly suit both the target audience and the brand, thereby encouraging customers to make a purchase.
Parking garage
Smart, sensor-based lighting solutions have long since found their way into purely functional areas such as parking garages. This is hardly surprising, given that, in addition to reducing energy costs, they offer two key benefits: optimal visibility and enhanced safety.
