The Werkraum Bregenzerwald association of crafts and trade has found a new home in the Werkraum House in Andelsbuch. The visionary building designed by renowned Swiss architect Peter Zumthor features a large wooden roof and a façade made of glass that makes the landscape seem to pass through. Hence, the Werkraum House serves as a kind of showcase for promoting the work of Bregenzerwald craftspeople. Eighty local master workshops joined forces to form the Werkraum association. The Werkraum House serves as a hub and meeting point for building developers and architects and also accommodates exhibitions, events, a shop and a café. The unique architecture of the multifunctional building placed special requirements on the lighting system.

During the design stage, highest priority was therefore given to a flexible lighting solution to enhance the building's architecture and ensure high lighting quality. In addition, the lighting scenario creates a pleasant atmosphere for visitors and staff. The Austrian lighting expert Zumtobel was called in because both the client and the architect needed a top-class partner with international experience and premium advisory skills. Zumtobel developed a custom-made lighting concept involving a number of special solutions for the various functional areas in the Werkraum House. For the part of the building that is open to the public, where various Werkraum members exhibit their work, Zumtobel used 100% cutting-edge LED technology.

The LED option cannot fail to impress thanks to its easy integrability into a lighting management system, so that the lighting can be flexibly controlled whenever events or exhibitions are held. “Lighting is especially important when it comes to presenting the achievements of our craftspeople in the right light in a targeted manner. On the other hand, it is precisely the light, in combination with acoustics, that sets the stage for a room's atmospheric qualities. Here at the Werkraum House you can see a sophisticated combination of artificial lighting and daylight,” says Managing Director Renate Breuss. In order to ensure perfect room acoustics, the open hall of the building where events are held was fitted with a thickly cushioned coffered ceiling made from timber. Zumtobel used a specially designed suspension system to install some 160 LED spotlights of the Panos Infinity range in this area. These downlights provide uniform ambient lighting as well as especially good lighting quality and are also highly efficient. Additional accent lighting and excellent colour rendering are ensured by nearly 90 swivelling Vivo LED spotlights, also fitted with a special pendant suspension system, which are used mainly for highlighting individual exhibits. Hence, Vivo provides accent lighting, creates contrasts and puts the focus on the exhibits, ensuring a fascinating art experience for the visitor.

In order to allow simple connection of the luminaires to the power supply and lighting control system as well as integration of an emergency lighting system, the Tecton continuous-row lighting system is used. This allows quick adjustment of the lighting solution to changing requirements thanks to no-tool installation. Moreover, Zumtobel has proved its flexibility in implementing individual requirements by providing a custom solution for the staircase and sanitary areas. Special downlights were flush-mounted in the concrete ceiling. They provide ideal lighting conditions to facilitate orientation and guidance and at the same time enhance the room's architecture. For emergencies, Zumtobel has installed Puresign and Resclite LED luminaires in the building. On the basement level, perfect orientation is ensured by suspended Tecton luminaires fitted with fluorescent lamps and rugged Scuba luminaires providing uniform lighting.

Zumtobel. The Light.

The film titled “Your light in a world of change” was created in collaboration with the Boros agency and the Zeitsprung Commercial film production company. The 1:30-minute film is an impressive and emotional story of how Zumtobel seeks to provide perfect lighting quality for people while protecting the environment. “Zumtobel stands for a new quality of light: the design-oriented lighting solutions we provide originate from our vision – to create the best possible light for people and the environment. We want to use light to make work easier, create worlds of experience and improve communications and safety. The film communicates this message very successfully,” says Stefan von Terzi, Director Marketing Zumtobel, who is very pleased about the award.

The plot revolves around the modern urban individual of the 21st century and the role light plays in people's everyday life. Live footage cleverly combined with 3D animations shows how lighting solutions adjust to the respective situation and people's needs in a world of change. The audience follows a man on his way through everyday life, witnessing how light makes living and working easier, enhancing his sense of well-being while increasing the energy efficiency of buildings.
“A good image film not only communicates the messages of a brand but addresses the target group and its needs in every detail. Our corporate production for Zumtobel is a perfect example of a film that credibly and emotionally communicates how a company uses innovative technology to improve the modern individual's quality of life,” says Christian Boros, CEO and Creative Director of the Boros agency, explaining the concept behind the film.
Zumtobel's image film also managed to win this year's “intermedia-globe Gold Award” and “German Design Award Special Mention” prizes.

Zumtobel. The Light.

No matter whether you work at a computer or tablet PC, use a smart phone, attend a meeting or hold a presentation: the LED luminaire range cannot fail to impress on account of its perfect lighting quality without producing any glare. This is made possible by the patented micro-pyramidal optic (MPO+). The diffuser layer of the optic resolves the LED points uniformly, ensuring perfectly glare-free light. Even at high luminous flux levels, luminance is consistently reduced, providing pleasantly distributed light even at steep radiation angles. Two colour temperatures are available for the luminaire range (3,000 K and 4,000 K). With a luminaire efficiency factor of up to 105 lm/W, the luminaires reduce the building's energy consumption, thus making a significant contribution towards sustainable added value.
All luminaires of the Light Fields evolution range boast excellent lighting quality and energy efficiency levels. Innovative technologies are used in various luminaire types with the aim of providing the best light for people in many different office situations.
For the recessed, surface-mounted and wall-mounted luminaires, Zumtobel has developed the 3Dprotect reflector. The reflector (patent pending) is both protection and optic at the same time. Its 3D structure protects the LED modules during installation, preventing damage from electrostatic discharge. At the same time, the structure's high reflection factor allows to increase the luminaire efficiency level.

The slimline design with a height of only 28 mm is made possible because the light emitting diodes have been integrated into the frame of the pendant luminaire. In order to obtain a well-balanced indirect/direct light ratio, LED light is emitted downwards thanks to litePrint light guide technology. The precisely calculated dot matrix of the litePrint light guide ensures uniform illumination of the complete light emitting panel. At the same time, an exactly defined light component is directed upwards, in specific regions, via openings in the luminaire housing, so that no extra LED modules are required for the indirect component.

Plenty of creative scope for modern office environments that are often modified is provided by the free-standing luminaire. Available with three different luminous flux levels (7,800, 11,000 und 14,800 lm) as well as warm and intermediate colour temperatures, the Light Fields evolution free-standing luminaire offers a variety of application options. The swarmControl technology used here is characterised by two functions that ensure a new dimension of individual lighting quality at workstations: the corridor function and the presence-based function. The fiormer primarily provides for safety and orientation, as the luminaires are dimmed up one by one by means of a built-in presence detector, thus indicating the way to the workstation. The presence-based function, on the other hand, ensures ideal lighting conditions with a mean illuminance level of up to 500 lx at the workstation, while users may adjust the quantity of light to their personal needs at any time using a control panel in the luminaire base. Neighbouring luminaires communicate via swarmControl, providing a cloud of light that creates a pleasant working atmosphere. The sensControl III function increases the free-standing luminaire's efficiency even more. The presence detector automatically switches the luminaire on and switches it off again when the workstation is left unattended. A brightness sensor monitors the illuminance level across the desktop and dims the luminaire depending on the quantity of daylight or artificial light available. Thus, up to 70 percent of energy can be saved, compared to conventional switchable free-standing luminaires.

This rounds out Zumtobel's LED spotlight range for retail lighting, which now includes suitable lighting solutions for small boutiques with low ceiling heights as well as for display windows and for shops with high ceilings, so that products can be set centre stage in a targeted manner.
The small size of the Vivo XS spotlight is made possible by a combination of compact LED mod-ules and innovative cooling. When looking for a suitable design language, the EOOS designers let themselves be inspired by the shape of a turbine. Thus, the Vivo spotlight makes use of the airflow that is essential for cooling.
Vivo M, one of the most successful products in the Vivo spotlight range, is now also available as an LED version. Thanks to its excellent colour rendering index of more than Ra 90, glare-free light and especially uniform light distribution, the compact and versatile spotlight cannot fail to impress when used for shops or display windows.
IR and UV-free technology makes it possible to illuminate sensitive products, such as groceries for example, very gently. Thus, fruit and vegetables remain luscious, meat stays fresh and textiles retain their colours.

Moisture-proof LED luminaires
Special conditions apply to car parks when it comes to lighting. In addition to the protection rating required (IP 65), the requirements in terms of material and quality are high as well. In addition to the existing portfolio of Chiaro II and Scuba LED moisture-proof luminaires, Zumtobel has now added models with higher luminous flux levels.
The Chiaro II 840 moisture-proof luminaire now optionally delivers 5,900 lm or 6,400 lm with a watt-age of 54 W and is available in either an intermediate or cool colour temperature.

The new headquarters of the Lauterach-based i+R Group (formerly i+R Schertler-Alge) with its long-standing tradition is considered a showcase project for sustainable building. On 9 October 2013, it obtained LEED Platinum and is now the first corporate building in Germany, Austria and Switzerland featuring this certification - and the only one so far. The highest level of LEED green building certification was awarded in the category “New Construction & Major Renovations”. Zumtobel made an essential contribution to implementing the clients' ambitious targets by providing an integrated lighting solution which scored not only in terms of efficiency, but also on account of its flexibility and user comfort.

Intelligent use of daylight in the entire building
The use of daylight plays a vital role in the entire building. Although one aim is to increase efficiency, the main goal is to create perfect working conditions for the staff, explains i+R Managing Director Reinhard Schertler: “For our new i+R headquarters, our top priority was to provide our staff with the best possible ambience. An innovative artificial lighting concept that maximises the use of daylight and thus has a positive impact on our employees' well-being was therefore of utmost importance to us.”

A daylight-based control system ensures a perfect combination of daylight and artificial lighting and creates optimum lighting conditions for the staff. Changes in lighting intensity are detected by sensors in the rooms and are automatically balanced. The resulting slow increase or decrease of the lighting level is hardly perceivable to the human eye. Despite the high degree of automation, the lighting solution leaves plenty of room for individual preferences, for all staff members can adjust lighting intensity levels, incident sunlight and temperature according to their personal needs.

Using this energy-saving lighting solution largely based on LED and further supported by presence detectors, the i+R Group was able to cut lighting-related energy consumption by up to 70 percent. In collaboration with the lighting designers of the Bartenbach Lighting Laboratory, Zumtobel managed to develop a lighting solution that provides a high degree of flexibility based on cutting-edge technology. Thus, it meets not only the specific needs of the i+R Group and complies with the high standards placed on LEED Platinum certified buildings, but is also sufficiently compatible and adjustable to fulfil the highest requirements in terms of sustainability and comfort in the long term.

Transparency thanks to environmental product declarations (EPD)
Zumtobel is the first company in the lighting industry to introduce environmental product declarations in compliance with the international ISO 14025 and EN 15804 standards. These so-called EPDs document the environmental impact of a product throughout its life cycle, for instance in terms of CO2 balance, recycling percentage, material composition or recyclability. In particular when it comes to building certification standards such as LEED, EPDs ensure the necessary transparency and are an essential component of the certification process.
In addition, Zumtobel supports its partners and customers during the building certification process by providing in-house experts for green building. Thanks to their comprehensive know-how, they are able to give valuable advice regarding the development of a sustainable lighting solution, in particular with respect to the different certification processes.

About LEED
LEED* (Leadership in Energy and Environmental Design) is an internationally recognised certification system for sustainable building. Besides environmental and economic aspects, it evaluates socio-cultural criteria such as room climate and workplace quality, but also attractiveness of location and technical innovations in design and implementation.

After nearly four years of construction work, the new campus of Vienna's University of Economics and Business (WU) will open its doors in October 2013. Some 23,000 students and 1,500 staff members will be researching, studying and teaching on the premises. In an area of about 90,000 square metres, six internationally renowned architects have created a unique ensemble of buildings. The heart of the campus is the “Library and Learning Center” designed by Zaha Hadid, which includes a large auditorium and the main library, among other things. Grouped around it are five other university buildings designed by Hitoshi Abe (Sendai/Japan), Carme Pinós (Barcelona), Eduardo Arroyo (Madrid), Peter Cook (London) and Laura Spinadel (Vienna). In addition to high design aspirations, the client attached high importance to environmental considerations during erection of the buildings. The whole campus was therefore built in line with a so-called “green building” concept, which also included installation of an efficient and sustainable lighting system. Austrian lighting expert Zumtobel, based in Vorarlberg, could not fail to impress the designers and architects involved by implementing a complete customised lighting concept based on energy efficiency and flexibility. Zumtobel also boasts many years of experience in the management and handling of large-scale projects as well as comprehensive advisory know-how. For the various university buildings, Zumtobel developed custom lighting solutions incorporating numerous pendant luminaires, continuous row lighting systems, light lines and moisture-proof luminaires, and in total provided some 12,000 luminaires, in addition to a continuous row system of seven kilometres length. Zumtobel also coordinated the installation and commissioning of the luminaires, in collaboration with four electrical contractors. The order volume for luminaires and installation amounts to more than EUR 7 million.

In the “Library and Learning Center” as well as in three department buildings accommodating various university faculties and administration units, Zumtobel has installed some 5000 LED luminaires from the Panos Infinity range. These downlights mainly illuminate the staircases, corridors and escape routes in the building as well as the sanitary areas. They provide guidance to students and university staff, help them find their way and ensure pleasantly bright ambient lighting. In doing so, Panos Infinity features particularly high lighting quality and excellent efficiency. During normal operation, the LED luminaires consume significantly less energy than any comparable conventional solution and boast a longer service life as well. Compared to conventional standards, the LED solution has a payback period of only five to six years. Over and above this, the LED downlights can easily be integrated into a lighting management systems, so that the lighting in the staircases and sanitary areas of the university buildings can be efficiently controlled using presence detectors. In department building D3, Zumtobel has also demonstrated its flexibility in meeting individual requirements by developing a special housing for the downlights, since they could not be installed in the concrete ceiling. In these areas, light is also provided by Slotlight II luminaires. The continuous light line without a luminaire unit looks light a narrow lighting channel and provides pleasantly uniform lighting. Slotlight II hase also been installed in the staircase of the “Library and Learning Center”. The offices in the three largest department buildings are illuminated by Claris II pendant luminaires. The minimalist luminaire blends harmoniously into the room, providing accurate light direction and perfect glare control – which is especially important at computer workstations. In the basements and technical services centres of the five building complexes, Zumtobel has also installed the rugged Scuba luminaire, which is particularly soil- and water-resistant. Its uniform illuminance also ensures perfect orientation.

More information on the “WU campus” project:

After six years of reconstruction, the Royal Cabinet of Mathematical and Physical Instruments at the Zwinger palace in Dresden has been open to the public since April 2013. Today, the experimental cabinet of the Saxon elector, established in 1728, is the oldest museum located in the Zwinger. The new exhibition design enhances the architectural structures of the palace and allocates more space to the fascinating collection. On a floor space that has almost doubled, 400 of the around 2,500 historic scientific instruments are still displayed. Terrestrial and celestial globes, burning mirrors, telescopes, clocks and watches provide visitors with an insight of how scientists used to explore the world in the past. The oldest exhibit is a Persian celestial globe from the twelfth century. Thanks to the materials used and their exquisite craftsmanship, many items are impressive works of art. Large exhibits are presented free-standing, while smaller and especially sensitive objects are protected by showcases. Visitors are invited to stroll around and make discoveries for themselves.

“The new exhibition layout of the Royal Cabinet of Mathematical and Physical Instruments sets the masterpieces of the collection centre stage. Thus, visitors can enjoy the beauty and technical brilliance of the devices made for the Saxon Court up close and down to the finest detail. Media stations and presentations of historic experiments using replicas illustrate the functions of the instruments that were used for active research on site, at the Dresden Zwinger” – this is how Hartwig Fischer, General Director of the Dresden State Art Collections, explains the new concept. The lighting solution plays an important role against this background: it accompanies visitors along the galleries and pavilions, facilitating orientation and ensuring that they can experience the instruments authentically, while at the same time allowing for targeted and gentle presentation.

LED opens up new opportunities
One of the most important decisions in the context of the new concept was the changeover to an LED-only lighting solution. The minimalist Supersystem LED spots blend unobtrusively into the interior, enhancing the Baroque architecture to optimum effect. It is, however, not only their reduced dimensions and low energy consumption, but above all the LED luminaires' excellent lighting quality that is so impressive: since the new generation of LED luminaires emits significantly less heat and the light they generate is nearly completely free from IR and UV radiation, potential damage is reduced to a minimum. Outstanding colour rendering of more than Ra 90 allows visitors to experience the exhibits in their natural appearance, which could not differ more in terms of materials and colours, for since silver is presented to optimum effect in cool white light colours, warm white is ideal for shades of gold and bronze.

Some 400 exhibits are set centre stage authentically yet gently by approximately 1100 LED spots. Thanks to their performance potential, accent lighting is possible even across longer distances. Here, the modular lighting system is able to proof its outstanding versatility. Depending on the lighting task, various Supersystem models have been installed in the entire exhibition area as well as in public spaces: recessed in the ceiling, surface-mounted or as pendant luminaires. Moreover, the individual spots can be swivelled in and out and rotated in all directions to provide selective accent lighting.

Another characteristic feature of the new lighting solution is the interplay of daylight and artificial lighting. In the bright galleries, which were originally not intended as museums and meet conservational requirements to a very limited extent only, a great deal of sensitivity was necessary to integrate air-conditioning and light-shielding devices in order to protect the precious and sensitive exhibits. Thanks to a built-in DALI unit, Supersystem is compatible to a variety of lighting management systems, and the spots can be subdivided into useful control groups, adjusted to the prevailing lighting situation and set to ideal luminous intensity levels to suit the respective exhibition situation. “The combination of artificial lighting and daylight has been especially adjusted to the requirements of the interior design. State-of-the-art LED technology allows even the presentation of sensitive exhibits in a contemporary fashion, while the original flair of the premises is preserved,” explain Raoul Hesse and Carla Wilkins, the design team of Lightvision, the lighting design studio in charge, who are very pleased with the results.

The newly opened “Museum Ton Schulten” in Ootmarsum is far more than an artistic biography of Ton Schulten, one of the most successful and renowned contemporary Dutch painters. In several rooms, he not only displays his own oeuvre, but also selected works of art by a number of international artists. He placed particular emphasis on an authentic, yet gentle lighting concept. In Zumtobel he found a partner who was able to perfectly implement his demands in terms of colour rendering quality, flexibility and conservational requirements.

Excellent colour rendering
Most of Ton Schulten's paintings show landscapes where nature shines in all her colourful splendour. Visitors are supposed to get the impression of standing right in the middle of such a landscape, experiencing it in natural sunlight. Against this background, the lighting solution faces particular challenges, for while bold blue or green shades are presented to optimum effect in cool white light, warm white is ideal for red and yellow. Hence, colour rendering and colour brilliance were very important aspects in Ton Schulten's decision for the right lighting solution. “I am highly satisfied with the result, because the paintings are presented in a very natural light so that they can unfold their full effect,” says a pleased Ton Schulten.
The solution was provided by a customised version of the Arcos LED spotlight system boasting a colour rendering index of up to Ra > 95 at 2700 K. In order to set the perfect lighting stage for presenting the artworks, a total of 230 spotlights were installed on Supersystem tracks. The dimming level can be adjusted directly on the spotlight, which allows individual adjustment to any exhibit. In addition, a variety of beam angles and an oval outline lens ensure sufficient flexibility to solve the most diverse lighting tasks.

Gentle and efficient illumination
However, the LED lighting solution was able to outcompete conventional halogen lighting not only due to excellent colour rendering, but also thanks to its compliance with conservational requirements. “As the new generation of LED luminaires emits significantly less heat towards the precious exhibits and the light they generate is nearly completely free from IR and UV radiation, we can ensure gentle illumination for sensitive objects as well,” says Barry Harmes from Zumtobel who was involved in the project from the beginning.
This was further corroborated by a study conducted by Zumtobel in collaboration with the Lighting Engineering Department of Darmstadt University of Technology. As part of this study, the quality of various light sources was tested on a real object of art, Picasso's “Harlequin” drawing, using predefined evaluation parameters. Basically, potential damage caused by the LED spotlight is significantly lower at comparable colour temperatures. At the same time, energy efficiency is increased by the LED spotlight, as the input of electrical energy is around 50 percent less than with a halogen spotlight. An additional benefit is the LED's long service life, combined with reduced maintenance effort.

The new hall complex of MCH Messe Basel opened its doors in April. Apart from the staggered hall structures arranged on top of each other, the new building designed by the renowned Basle architects' studio Herzog & de Meuron impresses on account of two other architectural features: on the one hand with a facade consisting of interweaving aluminium bands, on the other hand with the City Lounge - a covered square in the centre of the building with a spectacular opening allowing a view of the sky. A generously glazed ground floor provides for the transparency of the space, mitigating the bulky effect of the three-storey hall complex. The particular architectural virtues required a customised lighting concept that was developed by the renowned Bartenbach Lighting Laboratory. For the trade fair halls and the lobbies, the lighting designers have chosen a lighting solution by Zumtobel that scores high on account of its flexibility and energy efficiency. Thus, for the lighting of the lobbies, Zumtobel has developed a special-purpose luminaire that emphasises the architecture of the respective room to great effect. The LED light lines are installed in ceiling coves so that the indirect light follows the outlines of the room, creating a pleasant atmosphere. The light lines are fitted with warm or cool white LEDs. Moreover, RGB light lines are used for dynamic colour changes. In this way, a variety of lighting scenes can be created using a lighting management system.

Efficient lighting of the halls
The companies exhibiting their products in the complex of trade fair halls are provided with an area of approx. 38,000 square metres. Zumtobel has equipped this area, too, with a sustainable lighting solution. For perfect lighting of the retail and presentation halls, as well as in the warehouse, the flexible Tecton continuous-row lighting system is used with fluorescent lamps. Tecton is a continu-ous-row lighting system integrating a batten luminaire, lamps and a reflector within its trunking. This allows for easy mounting and reduces installation and maintenance costs. All functions such as power supply, lighting control and connection to the emergency lighting system can be inte-grated into the trunking thanks to a built-in current conducting section. In the area of the escalators, the hall lighting is complemented by the » Panos Infinity LED downlight range, which boasts excel-lent lighting quality and particularly high efficiency. Zumtobel has additionally fitted the trade fair halls with the Puresign and Resclite LED luminaires combined with compact fluorescent lamps for emergencies.

The new “vorarlberg museum” is an architectural and cultural gem situated on a prominent location right at the heart of the city of Bregenz. For as long as 150 years, it has been preserving cultural and artistic testimonials from the region of Vorarlberg. This time-honoured art collection has now been turned into a contemporary museum that arouses the visitor's interest already from the outside. The concept developed by Cukrowicz Nachbaur architects is based on the principle of continued building, combining tradition and progress in the region of Vorarlberg in a fascinating way. The heritage-protected three-storey administrative building was extended in height and supplemented with a new five-storey annex. The onlooker's gaze is immediately drawn to the facade's unusual relief that is characterised by 16,656 randomly arranged castings of PET bottle bottoms. They are intended to illustrate Vorarlberg's standing as a business location of international relevance, since the region accommodates the headquarters of Alpla, the world's market leader in packaging solutions. Inside the building, various exhibition areas form the heart of the museum; they posed the greatest challenge in terms of selecting the right lighting system. Therefore, the designers and architects relied on Zumtobel's expertise when it came to presenting some 150 years of history of Vorarlberg.

90 percent custom solutions to achieve perfect illumination
An important aspect in the building's redesign was to find a perfect lighting system for the various areas of the museum that can also be adjusted flexibly and quickly. In collaboration with lighting designer Manfred Draxl and with structural and technical requirements in mind, Zumtobel developed a customised lighting concept for the museum that combines efficient and gentle lighting with high lighting quality and perfect colour rendering. Moreover, all areas of the museum are uniformly lit with a warm white colour temperature of 3000 kelvin – this creates perfect lighting conditions for the exhibits as well as a pleasant atmosphere for both visitors and staff members.

About 90 percent of the lighting solution are custom solutions, including more than 1400 special luminaires. Furthermore, Zumtobel developed so-called multi-functional mono-points (MMP) for the exhibition areas and the foyer, which allowed unobtrusive homogeneous installation despite the building's slightly conical layout. MMPs are concrete casting boxes with a diameter of 90 millimetres. Recessed into the ceiling along a grid, they allow flexible integration of luminaires, loudspeakers or heavy-duty elements. The MMP automatically detects when a luminaire is installed and connects it to the central Luxmate Litenet lighting management system. Using Luxmate, the museum's entire lighting solution can easily be controlled with high precision. The system combines complex qualities to form a central unit that can be operated and configured thanks to especially developed graphic user interfaces via smartphones and tablets. In addition, Zumtobel has developed a special addressing concept for the illumination of exhibition spaces which allows for luminaires installed in retrospect to be integrated into the existing lighting solution immediately.

Innovative luminaires for demanding tasks
For uniform vertical illumination of walls, with the light centre at eye level, Zumtobel used wall-washers as suspended pendant luminaires with a length of 470 millimetres. Moreover, two pivoting LED luminaires – a simple recessed spotlight and a suspended version with five integrated spots – enable accent lighting of the exhibits. Above all, they boast very high colour rendering (Ra > 90) and excellent lighting quality. Their UV- and IR-free light is also particularly gentle on the exhibits. This combination is also used in the show depot where special objects are presented behind glass panels. Here, the luminaires are mounted on Tecton trunking. Tecton is a continuous-row lighting system which, thanks to its built-in 11-pole current conducting section, connects the luminaires with all functions such as power supply or lighting control. This allows absolutely flexible mounting positions and reduces costs for both installation and maintenance. Thus, additional luminaires can be added to the Tecton trunking for special exhibitions.

For perfect illumination of the foyer, Zumtobel relies on a combination of custom-made LED downlights, LED spotlights, HIT downlights and halogen spotlights. In the next room, the light-flooded atrium, daylight is enhanced by soft indirect lighting provided by minimalist Arcos spotlights.
In the museum café, Zumtobel added a decorative lighting installation consisting of some 30 halogen luminaires with fabric shades providing cosy light that entices guests to stay for a while.

In the administrative area, mainly luminaires with fluorescent lamps are used. Thus, the Freeline luminaire as pendant luminaire achieves perfect lighting conditions in the offices, thanks to its uniform light distribution. In the rooms where events are to be held, special lighting systems fitted with fluorescent lamps and halogen lamps provide both pinpoint and linear lighting. For the staircase of the new building, Zumtobel has developed another LED downlight, taking into account the sloped ceiling. In the staircase of the old building, the challenge was to follow the contours of the historic window arches and produce an appropriate light distribution.

With the opening of the new Light Center “La Lumière d’Uzès” in the heart of Paris, a new member is added to the family of around 20 Zumtobel Light Centers and three Light Forums all over the world. The Zumtobel Architecture Team applied a great deal of sensitivity to create a world of lighting experience in the historical building, built in 1867, on Rue d’Uzès. Unmistakable is the purist design by Zumtobel, which has skilfully enhanced the historical building's charisma. The team managed to create not only a space of approx. 250 m2 where light can show its versatility to full effect, but also an atmosphere that invites visitors to stay for a while. Situated right in the centre of Paris, Zumtobel is not just within easy reach, but also offers its partners and customers an inspiring meeting point and room for joint meetings, events and exhibitions.

The LifeCycle Tower One (LCT One) is the world's first eight-storey timber hybrid high-rise building.Based on the latest scientific findings in combination with innovative technologies and a resource-saving method of construction, LCT ONE indicates the way into the future of urban architecture.Inside the building, one can see the supporting structure made of timber; the external façade is clad in aluminium. The prototype was opened in 2012 and is mainly used for office purposes. For the LCT One, Zumtobel has developed an integral lighting concept including lighting management, emergency lighting and alternative lighting solutions for the offices. Apart from the modern and perfectly glare-free office luminaires as well as energy-saving LED corridor lighting, Zumtobel's Luxmate Litenet lighting management system is used in the LCT One. It controls the lighting, emergency lighting and blinds.

Intelligent lighting management
Luxmate combines complex system features such as use of daylight, presence detectors, integration of emergency lighting, and predefined room profiles in one central unit that can be easily operated. The daylight available is perfectly integrated into the lighting solution by the control system. The daylight sensor on the roof of the building continually monitors the incident light, ensuring that in each room only the quantity of artificial lighting is added that is required. Luxmate also controls the blinds, which in automatic mode can be adjusted to the prevailing lighting conditions and sunlight. This prevents glare and excessive build-up of heat in the rooms. Another feature of the lighting control system is the flexible change of colour temperatures and the quantity of light. Dynamic lighting demonstrably has a major impact on people's sense of well-being and productivity. Carefully thought-out lighting scenes are defined in advance, stored, recalled and modified as required. Moreover, Luxmate controls the entire LED emergency lighting system. This ensures low maintenance effort.

The latest in lighting technology: flexible and user-oriented
Panos Infinity high-performance LED spotlights, among others, have been installed in the ceiling. The general lighting system also includes Supersystem spots for accent lighting. The lighting concept is backed by presence detectors, which allow for intelligent control and lighting.This means that perfect lighting is available only when it is actually needed. The presence detectors used for the lighting solution also control the heating. In order to reduce energy consumption, presence detectors have been installed in the transit areas, corridors, toilets and in the staircase as well.

Exemplary energy efficiency
Using an intelligent lighting management system such as Luxmate, energy can be saved on a permanent basis: presence detectors or pre-defined switch-on times allow for potential savings of 20 to 40 percent. By making optimised use of daylight, up to 75 percent of lighting energy can be saved. Using dimmable luminaires, energy consumption can be reduced further by some 25 percent. Properly coordinated control of lighting and blinds reduces the cooling load of a building and improves lighting quality as well. The result is greater independence in the face of energy price increases and a sustainable drop in costs and CO₂ emissions.

After having been closed for more than 10 years, the Kunstkammer was presented to the public again on 1 March, with the explicit goal of making the history of the Habsburg collection and its most important figureheads known to an interested contemporary audience. The highest conservation requirements, content-related didactic criteria, but also emotional factors played an equally essential role for the new presentation of the Kunstkammer. Yet, the 2,200 exhibits included in the collection could not be more different in nature: among the highlights are outstanding works of the goldsmith’s art, such as the famous Saliera by Benvenuto Cellini, first-rate specimens of sculpture, such as the Krumau Madonna, masterly bronze statuettes, filigree ivory objects, but also precious clocks, games and scientific instruments.

Discus Evolution – LED spotlight system
The Discus Evolution LED spotlight system results from further development of an existing luminaire and cannot fail to impress on account of its perfectly matched light source and optic. The spotlight's flat design is now even more contemporary and minimalist. The delicate yet robust design of the spotlight created by the internationally renowned Vienna-based EOOS design studio was created for accent lighting and sales-boosting presentation of goods. The spotlight's innovative thermal management using a passive cooling system with radial fins is an integral part of the de-sign concept. Discus Evolution is available with an unobtrusive black or white housing and suitable both for installation on tracks and for recessed installation.

Elevo – LED spotlight
With just 3.5 cm, the flat Elevo LED spotlight is reduced to minimum height. It emphasises façade features, relief slabs and projecting features, backlights surfaces uniformly and sets tall columns and portals centre stage with equally striking effectiveness. The flat, compact design of the Elevo LED spotlight turns it into an inconspicuous integral part of the façade that is invisible to passers-by yet highly effective. Elevo's design was created by the internal product development team of Zumtobel Lighting GmbH.

Pan – recessed LED luminaire
Product development of the Pan recessed LED luminaire focused on accentuating windows, para-pets and alcoves. Thanks to its extremely compact design, the Pan recessed luminaire can be completely integrated into the façade structure. An anti-glare device especially developed for this luminaire eliminates any trace of undesired glare. Precise light distribution sets Pan clearly apart from bulky floodlights that illuminate large areas of façades and look out of place in the daytime. The Pan recessed LED luminaire was created by the internal product development team of Zumtobel Lighting GmbH.

Onlite Puresign 150 – emergency lighting
Zumtobel is also collaborating with the renowned EOOS design studio to develop escape sign lu-minaires boasting clear functionality and elegant shapes. At a width of just 20 mm, the Puresign 150 luminaire is strikingly slim, even in the duplex version. Thanks to cutting-edge LED and lighting technology, the pictograph is illuminated highly effectively and uniformly. Rotatable ERI spots on the underside ensure that the emergency luminaires can be specifically adjusted to the building's requirements. For the new generation of Puresign, four new installation options have been added to the existing product portfolio: recess into walls and ceilings, surface mounting using cords, and a remote box version.
