The concept submitted by Zumtobel managed to win a public invitation to tender. The experience and know-how about the effects of light on sensitive artworks were decisive for the operators of the National Museum.
The LED spotlight is perfectly suited for accent lighting. Instead of 1100 halogen spotlights with an installed load of 100 W each, today 970 ARCOS spotlights featuring an installed load of 20 W each and 120 spotlights with 25 W each set the lighting stage for the large number of paintings and sculptures. One of the most decisive criteria concerned colour rendering, which was supposed to exceed RA 90. ARCOS mastered this requirement with a colour rendering index of RA 94 at a constant luminous flux, independent of the colour temperature, and considerably lower energy consumption than conventional solutions. Moreover, the nearly UV- and IR-free light emitted by LEDs is gentle on the exhibits.
The right light for any exhibit, thanks to tunableWhite
With artworks from ancient to modern times on display, the demands in terms of lighting could not be more varied at the National Museum. Thanks to built-in tunableWhite technology, the light colour can be adjusted to the material, colour and character of each individual artwork. Colour temperature adjustments can be made either manually at the luminaire unit or via the lighting management system. The lighting solution for the entire building is based on LEDs in combination with the BUTLER XT lighting management system including presence detectors – ensuring considerable energy savings.

Thanks to transparent façades and a glass dome in the foyer, daylight can enter the building's large hall. The lighting design, too, which was created by the design studio of BELZNER HOLMES / LIGHT DESIGN ENGINEERING (LDE) specialising in architectural and stage lighting and technically implemented in collaboration with Zumtobel, follows the basic architectural idea of translucence. In order to meet the high demands of the multi-purpose building, LDE developed a lighting solution that can be adjusted to various application options. Thus, lighting scenes required for specific occasions can be created – from symposiums to concerts, from a focussed working atmosphere to stylish receptions.
After a long trial and testing phase, the client opted for a customised lighting solution by Zumtobel. The basic idea behind it is to be able to dim the LED luminaires down to 0 percent without flickering to ensure HD quality for TV broadcasts from the Montforthaus. In collaboration with its offices in Stuttgart and Liechtenstein as well as Zumtobel, LDE designed a custom solution for the various requirements of this project. The new design was based on the modular PANOS infinity LED downlight range.
The MFH-PANOS custom solution is a unique innovation in the sphere of architectural luminaires worldwide, featuring continuous dimming from 100 to 0 per cent. Compared to previous standard products, MFH-PANOS is able to clear the last hurdle of 10 to 0 per cent with a soft transition and thus without flickering. In order to be able to select the perfect lighting scene for every occasion, MFH-PANOS allows to adjust the colour temperature variably from warm to cool white. The ratio of cool and warm white light can be controlled individually, depending on the requirements, via separate DMX or DALI channels. According to the required reaction rate, the installed downlights of 28, 30 or 40 W are equipped with DALI or DMX control, making it possible to address every luminaire individually.
In total, more than 2500 Zumtobel luminaires were installed in the Montforthaus, including some 750 MFH-PANOS custom luminaires in various versions. However, Zumtobel was not only commissioned to develop a custom solution: the intensive collaboration of all those involved was also characterised by continuous project support and individual adaptation to the required scope. In total, 18 luminaire types by Zumtobel were installed in the entire Montforthaus, including LIGHT FIELDS evolution in the stairwell, ONDARIA at the coffee shop and CRAFT providing task light for stage lighting.

Filigree versatile lighting systemSUPERSYSTEM – a convincing product
Flexibility and adaptability are fundamentally important for temporary exhibitions and for the arrangement of sculptures and objects in exhibition rooms. Additionally, the ability to integrate the lighting solution into the existing structures plays a major role, for the historical space was meant to be interfered with to the least possible degree by another architectural element.
After several sample presentations and in close collaboration with the authority for the protection of monuments, the lighting designers of Bonn-based Licht Kunst Licht AG opted for the SUPERSYSTEM lighting system by Zumtobel. It has not only convinced them through its minimalist design language, but also on account of its versatile applications: on the one hand, it provides for uniform indirect illumination of the vaults. On the other hand, it creates diffuse ambient lighting in the room, with only the vaults, but not the transverse arches, being bathed in light.
Direct lighting can also be added via fixed miniature LED lighting heads. The flexible lighting heads allow for adjustment of beam angles to the current exhibition by simply changing the optics. Thanks to SUPERSYSTEM's maximum compatibility, spotlights that had been used by the museum already before may also be integrated in the track segments installed at the bottom, if required to provide additional accents for art objects presented at the walls or in the room. Thanks to DALI lighting control, the staff of the museum is not only able to easily control both the indirect and the direct light components separately, but also to individually adjust each group of mini-LED heads.

|Lighting design:||Plan Ing, Ralf Wolters, Aachen (DE)|
|Electrical installations:||Elektro Mücher, Alsdorf (DE)|
Under the aegis of Ralf Wolters, the Plan Ing Aachen engineers' studio, a Zumtobel Partner within the Lighting Competence Program, was commissioned with adapting the lighting concept. The requirements were complex: first of all, the lighting concept was expected to substantially reduce operating costs. Then, special requirements as to cost effectiveness and observance of certain payback periods were associated with a funding commitment by the federal government. At the same time, the concept was supposed to take account of the latest findings in terms of conservation, which meant that daylight was to be excluded from the Cathedral Treasury completely, with ambient lighting being reduced to a minimum. The client also wanted the renovation to be carried out within two months, with the Treasury remaining open to visitors, which required a high degree of flexibility to keep inconveniences for visitors to a minimum.
Extremely demanding requirements in terms of conservational lighting
In order to protect the highly sensitive exhibits, master builder Helmut Maintz had the Zumtobel luminaires that were eligible for the illumination of the exhibits tested extensively by experts of Photometrik GmbH, Darmstadt, in order to assess the effects of exposure to light for each exhibit. The focus was on an LED lighting solution that provides for effective and at the same time gentle accent lighting with minimum UV/IR radiation.
The fibre network that had illuminated the historical objects already before adaptation of the lighting concept was maintained and used to illuminate the exhibits. However, the LV generators previously used were replaced by dimmable LED light engines. The new LED engines, specially developed for museums, exhibitions and art galleries, are about twice as bright as the former halogen solution.
In order to provide gentle accents for the precious exhibits, Zumtobel used ARCOS LED framing spotlights and ARCOS LED xpert as well as 200 compact miniature spots from the SUPERSYSTEM range. For ambient and room lighting, which was meant to be reduced to a minimum, 50 LED downlights of the PANOS infinity range were installed. Moreover, the entire Cathedral Treasury was equipped with presence detectors, in order to expose the art objects to artificial lighting during brief periods only; the light is turned off automatically in empty rooms.
Each luminaire can be addressed and dimmed as required via a tablet PC. The savings realised by the Cathedral Treasury thanks to the LED lighting solution installed by Zumtobel are formidable. Innovative LED technology provides for a reduction of energy consumption of some 70,000 kWh per year. As the new LED lighting releases considerably less heat into the room, energy savings will also be realised for the air conditioning system that constantly keeps the temperature at the Treasury at 18°C and relative humidity at 55%. Overall, savings of at least EUR 22,000 per year may be expected.
"We highly appreciate the excellent collaboration among all the contractors involved. By observing conservational and energy efficiency aspects, we manage to combine the past and the future at their most beautiful here at Aachen Cathedral Treasury and to preserve the Cathedral's treasures for posterity," master builder Maintz comments on the result.

Large exhibit pieces are presented free-standing, while small and especially sensitive objects are protected in glass showcases. In view of this, the lighting solution plays an important role: it accompanies the visitor through the galleries and pavilions, facilitates orientation and also highlights the objects in a targeted and gentle manner, allowing them to be experienced authentically.
A significant change within the scope of the renovation was the decision to use a 100-percent LED lighting solution. The minimalistic LED SUPERSYSTEM spots are integrated discreetly and feature low power consumption and outstanding light quality. The fact that the new generation of LED luminaires emits less heat and their light is virtually free of IR and UV radiation fulfils the stringent conservational requirements of the museum. Excellent colour rendering of more than Ra 90 allows visitors to experience the natural materials and colours of the exhibit pieces. Based on specific lighting requirements SUPERSYSTEM was installed in all of the exhibit rooms and in the public areas as flushmounted or surface-mounted ceiling luminaires or as pendant luminaires.
A further characteristic element of the new lighting solution is the interplay of daylight and artificial light. Thanks to the integrated DALI unit, SUPERSYSTEM is compatible with diverse lighting management systems. The spotlights can therefore be controlled in groups for adjustment to the prevailing light situation and to the ideal luminous intensity for the particular exhibit constellations.

ARCOS boasts technical features developed especially for this application: David Chipperfield designed the extremely compact spotlight for Zumtobel in 2008 and revised it in 2013. The architect contributed his extensive experience in building museums to the development of a technologically innovative design luminaire for the most stringent conservational requirements. Testing of the luminaires in the room was especially important to him. Also at the focus: the perspective of the user, which Chipperfield also included.
Cooperative design process
With the Jumex project, Zumtobel and David Chipperfield resumed the cooperative design process for several individual solutions: For the two exhibition levels the luminaire development team designed special features for ARCOS, including an extended arm, single sockets and LED versions with excellent colour rendering (Ra90) and a colour temperature of 4,000 K. They are also used in the 3rd upper floor for accent lighting. A continuous row lighting system provides for even illumination of the floor – because the complex roof geometry requires a detailed scenario for the interplay of natural and artificial light. Daylight enters this level through skylights in the sawtooth-like jags. The light is scattered by means of a multi-layer system of matte glass and semitransparent acrylic and is admitted into the room through matte white blinds.
At night and in the case of reduced light intensity, the ZX2 continuous row lighting system installed in the skylights and the configured ARCOS spotlights, with special lenses and filters, ensure optimal light quality for homogeneous illumination of the exhibits. The flexibility of the configuration here also allows alteration and division of the spatial dramaturgy of the total of 860 square metres, with no loss of the sense of spaciousness. Additional continuous row luminaires are installed for added, accented illumination of single objects in the room. Control of the respective luminaires in the gallery and office rooms is achieved by means of the lighting management system LUXMATE BASIC.

|“We wanted to show this unique collection in the right light, literally.”
Dr. Sabine Haag, director of the Vienna Museum of Art History
The Museum is a walk-in synthesis of the arts in itself, enhanced by a unique and multifaceted art collection that adds to the success and fascination of the Kunstkammer Wien. With respect to the new presentation, the main challenge was to create a contemporary lighting design that remains in the background and lets the exhibits take centre stage.
Hence, a collection that had not been open to the public for eleven years can now be experienced in all its modernness, multifacetedness and absolute quality. The intelligent integration of daylight results in softly modulated light, so that the collection is presented in a different lighting scene in summer than in winter, and visitors will perceive it differently in the morning light than in the evening.
“The atmosphere conveyed by the 16th century exhibits finds its continuation in the Starbrick chandeliers.”
As functionality was a prerequisite for installation of the chandeliers, the Starbrick had to be modified for the actual room situation, in collaboration with Olafur Eliasson. Of course, Ms Haag and her team were fully aware of the risk to polarise when integrating a contemporary element into a historical artwork complex. But after all, the Starbrick reflects many developments that the exhibits have already gone through. Like the 16th century exhibits, it represents a combination of cutting-edge technology, art, absolute perfection and an attractive appearance, not least because its crystalline shape is also found in many exhibits. Therefore, at a room height of six metres, a second level of artworks was created, but in contrast to the exhibits, these artworks do fulfil a function, too.
“It was clear to us that in order to present the best collection, we wanted to collaborate only with the best partners as well.”
Obviously, sustainable preservation of the exhibits had been given top priority. Against this background, the decision in favour of gentle and authentic LED lighting was a matter of course. Beside the ambition of creating an innovative and future-oriented solution able to llast for decades, in contrast to a temporary exhibition, collaboration in this project was above all characterised by unwavering trust in the partners' skills and their commitment to quality without any compromises.
|“This collection is one of the most important things I will exhibit in the course of my career.”
HG Merz, architect and museum designer
|“The success of this project results from the high willingness displayed by all those involved to approach one another and make compromises in order to bring out the best as a team.”
Dr. Franz Kirchweger, curator of the Vienna Museum of Art History
|“Throughout the history of art, existing laws and the creation of reality have been questioned many a time – this is why the Starbrick fits perfectly into the Kunstkammer.”

Another special feature of the building is the arena covering 1,200 square metres that welcomes visitors who enter the futuristic building. Predominantly lined with wooden panelling and fitted with high-quality oak parquet flooring, the arena boasts an open, warm and pleasant atmosphere as well as a direct view across the river and the city. Visitors are welcomed by a pleasant ambience inviting them to stay for a while in the coffee bar, restaurant or bar to get in the mood for the show. Usually, it doesn't take long before the many seat cushions placed on the terraced stairs are occupied, where guests can enjoy a wonderful view of Amsterdam. “The spatial centerpiece of the building, the “arena”, invites visitors of the museum to stay for a while. The room's unique geometry promotes social interaction to a great extent”, Roman Delugan points out. The STARBRICK installation contributes significantly to this effect. STARBRICK is a Zumtobel Masterpiece, a collection of exclusive works of lighting art which the luminaire manufacturer has developed together with renowned partners. The highly versatile lighting module was made by artist Olafur Eliasson in collaboration with Zumtobel. “The STARBRICK is a space-generating lighting module. Developing it together with Zumtobel we were able to create it for everyday use and living. I’m very excited to see it integrated into a public institution. The expandable system behind the geometric design enables the STARBRICKs to grow in all directions. For the new EYE museum foyer, the bricks form luminous cloud-like structures that conjure up the atmosphere of a cinema – stars for the stars”, explains artist Olafur Eliasson.

Emergency lighting remains invisible during the day-to-day operation of the museum because the ultra-modern RESCLITE LED luminaires are seamlessly integrated with the TECTON trunking system. These efficient LED luminaires have a recognition range of 16 m and ensure safe guidance in the event of an emergency.
Special optical fibre lighting outlets with different beam patterns and UV/IR blocking filters were used to illuminate the display cabinets. A STARFLEX light engine with a 100 W QR-CB halogen lamp with a dichroic glass reflector for optimum injection of light was fitted in line with the customer's requirements. Zumtobel's LINARIA batten luminaire is used to light the special table showcases. Installed flush with the top on the rear wall, this narrow light line does not interfere with the showcase's visual look and illuminates its interior uniformly and pleasantly.

The new extension of the Städel Museum provides approximately 3,000 m2 of exhibition space underneath the garden of the existing building. The hall is up to 8.20 m high and is spanned by an elegantly curved, seemingly weightless ceiling. Although it is an underground structure, the new extension is apparent on the surface, too. Visitors can walk around in the museum's slightly domed garden, which is now covered by a remarkable pattern of circular skylights illu-minating the new museum space.
These 195 skylights with diameters of 1.5 to 2.5 m form openings in the self-supporting, slightly domed ceiling of the subterranean hall. They allow daylight to enter the exhibition space below and are also used as a source of artificial lighting with a ring of LED elements that is fitted with warm (2700 K) and cool white (5000 K) LEDs– a custom solution developed by Zumtobel in collaboration with LichtKunstLicht lighting designers and schnei-der+schumacher architects. When it is cloudy, and in the evening and at night, these LEDs ensure that paintings and exhibits are uniformly illuminated.
Thanks to Zumtobel's tailor-made lighting solution, highly sensitive exhibits such as works on paper, for instance, can be displayed directly alongside room partitions where sculptures are illuminated. Illuminance levels can be individually adapted for each skylight as needed. Cus-tom-built Arcos LED projection spotlights with various optics can be plugged into sockets in the skylights in order to emphasise individual objects or pick out wall surfaces as required.
The client opted to use Zumtobel'sLuxmate Professional lighting control range to ensure ra-tional use of daylight: the lighting management system controls the use of artificial lighting from the skylights depending on the amount of available daylight and the required or maximum lighting levels, according to specifications, for the exhibits that are on display.

“What is required for a project to succeed is undisturbed and challenging communication be-tween manufacturer and designer that can sometimes even become passionate on a matter. The outstanding result shows how good this has worked for us."
Andreas Schulz, Managing Director, Licht Kunst Licht
“The way we designed the building, we made sure that all benefits the Städel ensemble had before would be maintained. In addition, the new rooms are spectacularly visible from the street thanks to the domed lawn and the skylights. From a technical point of view, sustainabil-ity is ensured by modern air-conditioning technology and above all the lighting system based on LED technology and a large daylight component.”
Michael Schumacher, Architect, schneider+schumacher
“Our task was to find an integral lighting solution for the complex requirements, among others, to lighting quality, colour rendering and lighting based on conservational aspects. Our ability to develop custom solutions and the co-operative partnership with lighting designers and archi-tects enabled us to create this special LED lighting solution. By combining intelligent control with state-of-the-art LED technology we were able to develop an absolutely unique and flexible lighting concept that allows to provide the best light at any time for unlimited enjoyment of art.”

For a long time, the Palazzo dell’Arengario near Milan Cathedral lead a miserable existence. After being converted into the museum of 20th century Italian art, it now shines in new splendour. The austere building from the 1930s was turned into a multi-faceted art museum. A tour of the collection, which comprises 400 works - from futurism up to Arte Povera -, is also a walk through the city's history: city views that are deliberately positioned like paintings resemble still lifes.
Although the facade has hardly been changed (only the bricked up round arched windows on the middle floor were glazed), the tower-like building seems like a transparent shell, as if backlit, allowing glimpses into its new interior. Behind the large glazed surfaces, Lucio Fontana's "Struttura al neon" lighting installation sends out rays of light onto the cathedral square.
To achieve this new openness, the building was mostly gutted. Now, a ramp spirals upwards leading visitors to the exhibition rooms. The glass facade surrounding the ramp offers insights and views that change with every step you take, like in a film sequence. Point-shaped luminaires track the curved surfaces on two levels: downlights recessed into the ceiling mark the way, illuminating the ramp's surface, while small LED spots on the balustrade irradiate blue/green light into the interior.
Light as a creative design tool also plays an important role at the interfaces of the various divisions of the museum. "Portals of light" mark the entrances to the exhibition rooms. In this context, wide-area lighting modules act as door frames emphasising the transitions to the more quiet gallery rooms. Here, the modular CIELOS luminous ceiling provides uniform, diffuse ambient lighting, leaving the leading part to the art objects. The CIELOS modules are arranged depending on the respective floor plans either as linear continuous rows or in a square; they are controlled via the central LUXMATE lighting management system. As opposed to the wide-area lighting of the ceilings in the galleries, the access areas are illuminated by vertical light lines installed flush in the walls.

The exposed concrete building of the Museo nazionale delle arti del XXI secolo - MAXXI - is like a sculpture featuring a multi-faceted interplay of light and shadow. The sunlight falling through incisions and apertures draws bright patterns, shadows travel over the wide forecourt, the inside and outside being interwoven in subtle ways. In the form of canopy roofs, the projecting building units guide the visitor into the lobby that extends over the entire height of the building. Intersecting stairways and bridges connect the five exhibition levels, a "vertical piazza" directs the flow of movements. Natural light floods into the building from the glazed roof to the floor, finely tuned by a specially developed luminous ceiling that incorporates indirect lighting from fluorescent lamps that can be switched on additionally as needed. This combined system provides for uniform ambient lighting. In addition to that, artificial lighting is used as a deliberate creative tool to dynamically highlight the routing system. Stairways and bridges are turned into "bearers of light". Their translucent, glittering undersides equipped with fluorescent lamps behind light-scattering film and acrylic glass seem like luminous display cases.
The spaciousness of the entrance hall is continued into the exhibition rooms. With straight, curved, tilted walls, with corridors, ramps and terraces, the sequence of rooms unfolds in a surprising and at the same time complex manner. The rooms run parallel with each other, they intersect, interlock, form cascade-like levels, meandering in various directions, just to meet again somewhere else. The lead in the lighting concept is played by natural light. In addition to that, complex luminous ceilings provide for natural rendering of colours and surfaces. All the technical components are integrated in the narrow roof girders (steel trusses clad with concrete elements): they carry the exterior grids serving for solar protection and the diffusion of light, as well as the two glass levels and the blinds. Uniform ambient lighting is ensured by the dimmable fluorescent lamps installed on both sides of the ribbed girders over their entire length, behind translucent acrylic glass scattering the light. The blinds and light output are controlled by the Luxmate Litenet lighting management system according to the position of the sun and depending on the lighting situation required. Additional spotlights for accent lighting, but also video projectors and light partitions can be installed on the trunking system integrated at the bottom of the girders.

Featuring a collection of 46,000 objects of medieval or contemporary art, the Museum M acts as a bridge between history and the present. "Centuries old and vitally alive" - the tenet of the city of Leuven also holds true for the new museum: the spacious complex has several entrances opening it towards the historical city centre; it combines different architectural styles and eras, presenting itself as lively, multi-faceted art district.
The former academy building and the Vander Kelen-Mertens Palais - both buildings were integrated into the Museum M - have been renovated carefully according to the rules of the preservation of monuments, and they were linked with the modern building via a bridge. A total of 6,500 square metres of exhibition area are spread over this labyrinth-like museum complex. While the colourful splendour of ages long past is perceptible in the ancient building, in relatively small rooms with wooden ceilings and wall panelling, the new building is all sober minimalism.
Instead of monotonous, isolated rooms, the architect has designed an extremely varied museum tour that may be used flexibly, with spacious, high rooms, and then again smaller, lower ones. The lighting concept pays tribute to the character of the individual rooms, responding with great sensitivity to their specific spatial characteristics. Thus, the officially protected art rooms of the existing buildings are illuminated by delicate SUPERSYSTEM tracks floating below the ancient wooden ceiling, suspended on almost invisible cords. Vertical wallwashers provide for flexible, expressive accent lighting of the objects on display, as required. For the general, compact and flexible lighting, 3-phase tracks with spotlights are used. In the clearly more spacious White-Cube rooms of the new building, TEMPURA spotlights incorporating LED technology have been installed on TECTON trunking. The spotlights’ colour temperature can be adjusted in the range of 2700 to 6500 Kelvin according to requirements. Moreover, by using LED light, any impairment of the art objects through IR or UV radiation can be avoided.

King Louis II would have been delighted. The sovereign, who had always been very open-minded about innovative technologies, had a number of sensational technological advancements implemented during the construction of Schloss Neuschwanstein. With its new LED lighting system, Schloss Neuschwanstein has ventured a step into the twenty-first century. In this way the State Apartments are illuminated efficiently and, above all, gently. All areas open to the public are gradually going to be fitted with individual LED lighting solutions.
The greatest concern of those in charge is the heavy burden on historical furniture, textiles and paintings caused by UV and IR radiation. In order to not interfere with the historical room impression, visible light sources should be avoided to the greatest possible extent. Another requirement is that existing points of installation or clamping devices must be used in order to avoid any impairment of the historical structure.
The clients were particularly impressed by the compact dimensions and UV-free light of SUPERSYSTEM. Architecturally speaking, the LED lighting system is very discreet, while setting highly attractive accents - even from a greater distance. Owing to different optical attachments, the LED spotlights generate varying beam patterns with only 2.5 W. The magnificent colours in the cupola of the Throne Room are illuminated impressively by TEMPURA LED spotlights. By choosing colour temperatures between warm (3000 K) and cool light (6500 K), details can be emphasised to optimum effect, and those in charge at the museum can always modify the lighting according to requirements.

The new Harpa Concert Hall rises up like a giant cut crystal in front of the jagged coast of Reykjavik harbour. The honeycomb elements of the façade make up a dazzling sea of multicoloured highlights. Refl ections on the water surface reinforce the association with a natural phenomenon, calling to mind mysterious northern lights. The sparkling Concert Hall and Conference Centre that now adorns the cosmopolitan capital of Iceland was designed by Henning Larsen Architects in cooperation with the Danish-Icelandic artist Olafur Eliasson, who was responsible for the characteristic appearance of the outer envelope. The area in front of the building is bathed in mystical blue light emanating from hidden sources of light, transmitted inside the building through glass fi elds. Olafur Eliasson and Zumtobel developed a special new type of luminaire, the shape and colour of which permits almost invisible integration in the prism structure of the façade, lighting it up with LEDs. Inside the crystalline outer envelope, visitors can expect to experience music in a new dimension. The large three-tiered concert hall with a blazing red interior is named after one of Iceland’s most beautiful volcanoes “Eldborg”, meaning “Fire Castle”.
