Industrial charm with new appeal
In 2005, a new way of using the property from the seventies had to be found. It was generally agreed that not just another office complex would be built on this site, right in the heart of Zurich-West, a district that had meanwhile blossomed out into a cultural hotspot boasting the industrial charm of days gone by. Hence, based on a feasibility study, it was determined that the 24,435 m² Toni-Areal was to be transformed into the new central location of the Zurich University of the Arts (ZHdK) and the Zurich University of Applied Sciences (ZHAW). In the subsequently launched architectural competition, the project design submitted by the EM2N architects' studio came out first, and the building application filed in autumn 2007 laid the foundation for the ambitious renovation and new building project involving an investment volume of CHF 350 million.
Right on time for the start of the autumn term in September 2014, approx. 5000 students, lecturers and staff members could move to the new premises. In addition, not only 100 new flats including an accessible roof garden and a car park accommodating 240 cars, but also rooms for exhibitions, events and spaces for commercial use were created. A contemporary infrastructure was developed that not only allows interaction of various disciplines at one location, but also ensures the university's high educational and service quality as well as its international competitiveness.
The design of the campus building picks up the former industrial building's architecture, creating a heterogeneous space where different interests are reconciled, also in terms of lighting. The lighting concept toys with this heterogeneity. Its aim is not to produce uniform brightness, but to have the luminaires arranged so as to divide the space into zones and create a dialogue between light and dark. Also, the lighting solution is as capable of transformation as is the Toni-Areal site itself. On the one hand, ideal lighting conditions for learning and communication are produced; on the other hand, the creative ambience is enhanced and students are provided with the right light for their exhibition areas.
The key role in implementing this lighting solution is played by a modular luminaire system that meets the high demands in terms of flexibility and customisability: TECTON, which is able to fulfil complex functions and a variety of lighting tasks thanks to its versatility, compatibility and expandability within one system. The continuous-row lighting system is based on trunking incorporating an 11-pole current conducting section. All functions such as power supply, lighting control and connection to the emergency lighting system are integrated into this multi-functional trunking unit. In order to illuminate 1400 lecture rooms, seminar and training rooms, more than 33 kilometres of TECTON trunking were installed.
At peak times, more than 600 electricians were working on the construction site, installing more than 5500 TECTON continuous-row luminaires, among others. As required, a variety of optics and louvres were used, which can also easily be replaced or added if the requirements placed on the lighting solution should change.

Campus of Knowledge
The centre of the spacious nine hectare campus is the Library & Learning Centre (LLC) designed by Zaha Hadid. With its sharp corners and bold lines the expressive building, which leans forward far over the forecourt, evokes the image of a futuristic command centre. The interior is also dominated by spaceship aesthetics with dramatically slanted walls, rounded edges and long, narrow walkways extending from one end of the room to the other. The LLC is flanked mainly by black & white, plain office and institution buildings. In striking contrast: the Teaching Center (TC), clad in Corten steel, and the red-orange-yellow Institute Cluster designed by Peter Cook.
The heterogeneous styles of the six planning architects also presented a challenge for the light planners. On the one hand it was necessary to adapt the light concept to the particular architectural character, alternating between subdued and dynamic; on the other hand, the number of products had to be reduced to a minimum with a goal towards efficient facility management. The end result: a total of 12,000 luminaires – including pendant luminaires, hidden cove luminaires and numerous individual light solutions – as well as seven kilometres of continuous row lighting.
The entire campus, which currently accommodates about 23,000 students and 1,500 employees, was designed in accordance with the green building concept. Of course, that also means installing efficient and sustainable light products, such as the SLOTLIGHT II light line, the CLARIS II pendant luminaire and LED luminaires of the PANOS INFINITY series. All lighting systems in the buildings are controlled by a common KNX bus controller; motion detectors are used to control the lights in the stairways and sanitary facilities, while the offices are equipped with a special light control system to optimise the use of daylight. In comparison with conventional solutions this combination uses far less energy.
One special aspect of this project: In addition to Zumtobel’s role as a commercial enterprise, the company was also responsible for the entire installation, in the form of a joint venture with four electrical installation companies.

For these “bed rest studies” alone the “:envihab” has twelve rooms, in addition to the afore-mentioned shower rooms, special carts, a completely furnished kitchen and a common room. Although not necessary for lying in bed for extended periods, it is needed for isolation studies on a group scale, simulating long journeys through space.
The “:envihab” sleep and physio-lab also deals with terrestrial matters. It is used, for example, to examine the effects of shift work, lack of sleep or irregular working hours – and the effect of light. The circadian rhythm of daylight defines human waking and sleeping phases – receptors in the retina register the change of short-wave light and control sleepiness by means of melatonin production. In the sleep labs this rhythm can be systematically delayed or even interrupted – in order to observe the effects on well-being, health and performance. The diffuse and variable light needed for these tests is provided by the luminous ceilings equipped with LEDs in the rooms, and also where the test subjects are examined by means of PTE (positron emission tomography) scans.
In cooperation with the DLR Institute Zumtobel developed the modular luminous ceiling, whose CIELOS LED elements can generate precise and dynamic luminous colours and luminances by means of the LITENET control system. The brightness can be dimmed continuously down to a minimum level without flickering and the RGB spectrum can also be varied as needed. The low installation height, durability and user-friendly maintenance were further arguments for an LED luminous ceiling.
The purpose of these circadian studies is not only to examine the interaction of light and the condition or performance of the test subjects, but also to clearly define the qualities of light necessary to prevent fatigue at the workplace or to reduce the effects of jet lag.
Of course, the “:envihab” does not consist only of the sleep and physio-lab; the complex comprises a total of eight research modules under one roof. The architecture is literally based on the house-in-house principle. All of the modules and the large auditorium are designed as separate structures beneath the roof construction, which defines the outward effect of the building and is actually more than just a roof. The steel support structure contains the building’s entire technical infrastructure. This was somewhat of a trick, since the 3,500 square metre interior – rather uncharacteristic for a research facility – presents itself as orderly and clearly structured.
The “:envihab” is also a symbol for a new self-conception in research – in the past, such facilities tended to be purely functional in nature; today, the publicity effect is increasing in importance. In addition to the exterior, this paradigm shift is apparent especially in the interior. The entrance on the ground level is connected by a wide and pleasantly designed stairway to the spacious entry hall. The large auditorium with seating for 150 and the restaurant infrastructure are designed as a location for external events. Although situated below the ground level, the entire interior is surprisingly illuminated by daylight – this is achieved not only by the wraparound glass strip between the floor and ceiling, but especially by a total of six light wells that penetrate the building vertically at different locations, establishing a connection with the sky – in keeping with the central theme of the DRL, which the architects adroitly interpreted.
The incompatibility of public utilisation with sensitive fundamental research necessitated a separation of the two areas by means of a partition. But since they are made of glass, the room volume can be experienced in its entirety together with the individual modules. In the centre, for example, there is a cylindrical module with solid concrete walls, with a short-arm centrifuge inside. This apparatus is used to explore whether increased gravity can be used selectively to counter the health risks of weightlessness. Initially in relation to long-term stays in space, the results will also bring new insight into down-to-earth issues such as osteoporosis, muscle degeneration and circulatory disorders.

The curved administrative building with its Z-shaped ground plan offers maximum flexibility in the interior. Since it is already apparent today that the administrative and instructional requirements can change in the future, the widespanned supporting structure allows for different room layouts. The wraparound façade banners emphasise the horizontal structure and universal usability of the building.
The high windows allow ample daylight to enter from all sides to ensure even illumination of the office areas. For supplemental illumination of the workplaces with artificial light the architects sought a solution that supports the desired flexibility in the spatial layout while enhancing the formal, reductionist design of the building. Together with the agency a∙g Licht based in Bonn a product was found that optimally fulfils all of the required criteria: ECOOS. The building owner was convinced not only by the high-quality light, but especially also by the long-term lower operating costs.
By way of complete contrast, the motor test centre is an introverted, elongated hall structure. The façade of darkened fairfaced concrete with only narrow slit windows emphasises this character. Inside, the building is rigidly organised, structured and adapted to the spatial and technical conditions of the test equipment. Despite the narrow windows, which make it possible to see the interior from outside, rows of windows in the roof allow sufficient daylight to enter the two-storey hall. The TECTON continuous row lighting system provides for optimal workplace lighting and orientation. Time-tested in industrial use, TECTON combines all of the elements needed here: optimal lighting quality even from large heights, flexible utilisation of space, high efficiency and easy maintenance.
A special feature is the advanced energy concept: the enormous waste of heat generated by the motor test runs can be used to heat the building. A foresighted approach to efficient reuse of energy, which benefits man and the environment.

Situated halfway between Europe's and North America's established science centres, Reykjavik University is turning into a new research and technology top spot. Its architectural design, too, deserves special attention: the individual faculties are arranged radially around a circular hub. The campus opens up in a fan-shaped manner towards the beach and forest areas surrounding it, incorporating them into the premises. Apart from endowing all of the rooms with the unique quality of a natural environment, this layout also permits optimum illumination and heating with natural daylight - a crucial aspect of the sustainability of the building, in which trendsetting technologies are not only part of everyday life but are also part of the curriculum.
For the major part of the building, the engineers developed a ceiling system made of perforated sheet steel blades, which was also intended to accommodate the lighting system. In order to meet the vast range of requirements in the best possible manner, the client organised a competition. Zumtobel's most convincing point: despite its small dimensions and the fact that it fully met glare control requirements, the T5 luminaire's light output ratio could be improved by more than 1.5 percent compared with standard technologies. This has been made possible by translucent lateral reflectors, optimised miniature louvres and a perfect lamp operating temperature. From the design point of view, the luminaire could not fail to impress on account of its modular system that is able to adjust to a variety of visual tasks in lecture halls, seminar rooms, offices, libraries and circulation areas - mounted on a gear tray, installed as a wallwasher or as a model with open light distribution.
The LUXMATE LITENET lighting and blinds control system has been developed further to take account of the special local lighting conditions characterised by the Nordic sun's shallow-angle radiation over long periods of time. In this way, high efficiency and maximum comfort were combined with the option of responding flexibly to changing area-use plans, with minimum effort. Most of the luminaires were supplied with so-called Dimming On Demand (DOD) ballasts, allowing for major cost savings as a large number of luminaires were installed.

With its translucent skins and round patios, the pavilion designed by SANAA is the new heart of the École Polytechnique Féderále de Lausanne's campus. In an area of 17,000 m², it accommodates a library, conference rooms, students' workstations, offices for researchers, cafeterias, a top restaurant, a book store, a multifunctional auditorium and - very Swiss - a branch bank. However, the Pritzker Prize-winning architects had definitely more in mind than providing functional rooms. The new building is meant to foster interdisciplinary exchange among scientists, and above all seeks to establish an appropriate position for EPFL in the global research scene.
The building is made up of a single large-scale room with casually arranged functional areas, radiating impressive openness. The dynamic topography of the floor and ceiling creates a fascinating roomscape, divided into zones by a variety of lighting scenes. In the process, the ceiling is not only changed by daylight but also reflects the artificial lighting back into the room. The building is certified according to the Minergie standard, and luminaires with a very high output ratio had to be installed because of the building's size and in line with SANAA's request for indirect lighting.
The specially developed luminaires have been installed as individual luminaires or in twin or triplet configurations, allowing to create any lighting situation required by using a single creative design element. Thanks to the luminaires' flexible fixture, a variety of different angles can be set in relation to the diffusely reflecting ceiling. Many of the total of 282 custom luminaires have been fitted with an extra 100 W halogen lamp for emergency lighting purposes, in addition to a 35 W HIT metal halide lamp with a special IOS reflector system. In the lobby and reception area, LED downlights and elegant light lines additionally provide functional lighting while setting creative accents. In the offices, which have been designed as circular booths, minimalist free-standing luminaires create a pleasant working atmosphere.

The new university centre of the Tomá Bata University in Zlín is a symbol of the city's investment into its citizens and their future – and an appropriate tribute to the visionary ideals of the philantropist and industrialist after whom it was named.
The building's extraordinary structure is based on two crescent-shaped units accommodating the reading rooms, classrooms and book archives. Between the units there is a spacious atrium lit from the top where people find space to relax. The staircase towers located at both ends of the curved façade form the main vertical link between the galleries along both sides of the atrium, giving the building an uncluttered, practical look. This very clear design, which is typical of architect Eva Jiřičná, with maximum functionality is also reflected in the lighting system.
The clear lines of the building are emphasized by equally clear SLOTLINE light lines installed in the rooms. Thanks to its calm, geometrical stylistic idiom, CLARIS II, which is frequently used in school buildings, could not fail to impress either. In the centrally located atrium, it has been installed as a continuous row system with a total length of 54 m. Both direct and indirect light is provided throughout the room, providing a uniform, warm and diffuse lighting scene. In the other main areas, SLOTLIGHT and MIREL II lighting systems have been installed to supplement the light reflected by the atrium. MIREL II louvre luminaires assembled to form architecturally striking light lines provide uniform, glare-free lighting for the libraries and computer workstations.
For highlighting the edges and lines along the windows and peripheral areas, fluorescent lamps have been recessed into the ceilings and walls, underlining the sculptural interior design. The Tomá Bata University is a trendsetting example of how to perfectly integrate lighting into a design concept.

The striking new building of the Royal Northern College of Music in Manchester's city centre attracts attention. Cubes nested into each other demonstrate monumental geometry seemingly in contrast with the building's purpose - the lightness of music. The building's very small floor area has been used to optimum effect by adding an acoustic buffer against traffic noise doubling up as a shop window for the college. Additional appeal is achieved by lighting in variable colours, which turns the space into a glowing light box with spectacular colour changes, attracting the attention of passers-by. Inside, the lighting system is supplemented by the flush-mounted LIGHTTOOLS lighting channel system incorporating four different lighting modules: spotlights, downlights, linear luminaires and wallwashers.
In almost every area, large windows and skylights allow plenty of daylight to enter the room. Where this is not sufficient, artifical lighting is added via the lighting management system. In concert with pleasant colours and ergonomically compatible furniture, rooms of experience are created that make students want to learn - flexibly and conveniently, and with a focus on saving resources.
According to Craig Jackson from Gifford and Partners, who specified the lighting, the lighting design was strongly influenced by the acoustically sensitive environment. “The luminaires must be robust and without parts which could reverberate from the sound of the instruments,” says Jackson. This special challenge has been met by the LIGHTFIELDS recessed luminaire, which, due to its special micro-pyramidal optic, provides extremely uniform, glare-free light, helping to increase the brilliant young students' concentration.

The new building of the Catholic University College in Bruges is a landmark characterised by architectural contradictions. The façade towards the street is closed, featuring only a single window in the study department, while the façade towards the campus presents itself extremely open. Exciting contrasts are created by a combination of steel, glass, concrete and wood. At the same time, the modular approach allows for adjusting the building to new studying requirements in the future.
The atrium has been designed as a three-dimensional junction featuring wide stairs, open galleries as well as seating areas and islands for studying. According to the architects' preferences, the building was to be fitted mainly with indirect lighting. The MIROS projector-mirror system provides an architecturally sophisticated and technically perfect lighting solution, illuminating the up to 10 m high rooms with uniform, glare-free light. The system's warm light creates a fascinating contrast to the rather cool concrete/glass architecture. Concludes Koen De Klerck: "Using both functional and atmospheric lighting we have sought to enhance the architecture and the building's surroundings even further. In the process, both flexibility and maintenance aspects have been taken into account." The projector-mirror system appears to be part of the building design, and has also been installed in the two auditoriums and the cafeteria.
The lecture halls and seminar rooms, which are accommodated in the three striking blocks, can be reached via the auditorium. In the classrooms, MIREL recessed luminaires installed flush in the ceiling provide plenty of light. In the circulation areas, a special section with indirect distribution provides pleasant, glare-free light.

The clients opted for the TECTON continuous-row lighting system to be installed in large areas of the building complex. Fitted with high-quality matt reflector optics, the continuous-row lighting system provides pleasant lighting conditions in classrooms and auditoriums, as well as in the reception area and in the library. All these rooms are fitted with suspended acoustic ceiling panels. This is why it would have been very difficult to use conventional recessed luminaires, which would also have required considerable compromise in terms of design. The flexible TECTON continuous-row lighting system proved to be the ideal solution. Like the acoustic ceiling panels, the track system can be suspended as well, so that the luminaires now match the architecture perfectly.
The TECTON lighting system installed at Gent University creates optimum lighting conditions in classrooms, and is also highly efficient.
Another argument in favour of TECTON is its pre-wired eleven-pole track: using the integrated DALI bus line, the luminaires installed in the library and the cafeteria enable daylight-based lighting control. The result is a lighting solution controlled via LUXMATE PROFESSIONAL which provides a pleasant lighting atmosphere 24 hours a day and at the same time reduces energy consumption considerably. In order to keep maintenance costs as low as possible, projector/mirror systems were installed in the entrance area and the five-metre high corridor zones, which allowed to mount the spotlights used at an accessible height so that only a minimum of time is required for relamping.
Quite different, however, is the situation in the cafeteria. Thanks to modern furniture and green transparent chairs, a playful touch is added to these areas – also because of the COPA D high-bay reflector luminaire used. The large roof protecting the footpath between the two buildings of Schoonmersen Campus is illuminated by high-pressure halogen spotlights and RAIN moisture-proof luminaires.

The new university building of the Cooper Union located in New York's East Village presents itself as an angular metal structure. The spectacular architecture designed by Pritzker Prize winner Thom Mayne boasts a lighting system based on an equally fascinating lighting design. During the day, the structure shines in white to metal anthracite grey; at night, it softly glows from inside.
This work by the California-based architect creates controversy among New Yorkers, breaking established conventions and being ahead of the times. As a sign of provocation, for instance, Mayne has made the elevator stop only on three out of nine floors. This feature ultimately directs the students' and visitors' attention towards the staircase, unless they have not been attracted earlier by its breathtaking architecture. Like a huge vortex, it ascends upwards across all the floors, opening up towards the sky. Through a large skylight, daylight enters and floods down right to the ground floor.
The upper floors are therefore flooded with bluish daylight, which, as it travels downwards, gradually mixes with increasingly warm artificial lighting provided by VIVO spotlights.
In the other areas of the building, the lighting concept is based on specific functions. In the laboratories, for instance, twice as many light sources have been used as in the seminar rooms, in order to make subtle colours differences and details more easily perceptible. The seminar rooms and numerous laboratories presented a special technical lighting challenge: the luminous panels installed in the ceiling had to be integrated in the heating and cooling modules also installed in the ceiling. A tricky task, yet readily taken care of on account of the building's general environmental compatibility. With this design, Thom Mayne has set new standards, not only in terms of visual attraction. As the first university building in the USA, the new Cooper Union building is about to receive the LEED Platinum Award, the country's most important environmental compatibility prize.

There are not many venues dedicated so completely to architecture and showing this in such an impressive way like the modern neo-classical Palais Chaillot on the Seine. Following careful renovation, the world's largest Architecture Centre was opened in the building's magnificent east wing in 2007. Since then, the prestigious building has accommodated several institutions that bring historical and modern architecture and France's cultural heritage together under one roof.
The lighting design of the spacious entrance hall on the ground floor imparts this area with a clear structure, enhancing visitor orientation and centralising access to the various areas. The light lines set in the ceiling trace the main axes of the hall along the monumental columns.
The open-access library with its high-ceilinged, flowing rooms houses some 28,000 books. Jean Francois Bodin has managed, without major interference with the fabric of the building, to create a functional, contemporary library interior. The reconstructed fresco cycle from Saint Savin sur Gartempe Abbey has been set centre stage using a luminaire especially developed for this purpose. The barrel vault of the 40 m long room is flooded by warm light provided by reflectors based on the TECTON system, which have been installed above the shelves on the wall.
The impressive gallery of architecture expands across the curved room occupying the complete second floor of the wide building tract. The central exhibition area is illuminated uniformly by seven large, backlit ceiling rotundas; the lighting can be controlled to provide a variety of illuminance levels, if required.
