Eleven years in the planning, five years in the making – a combination of brand new construction and renovation of the existing building dating from 1908 has transformed the » LWL-Museum of Art and Culture in Muenster into one of the biggest art museums in Germany. In many ways, the architecture can be seen to reflect the 1,000 years of art on display. Old and new are merged into a single architectural unit to showcase works from the Middle Ages to modern times, ensuring a unique visitor experience. "Art needs daylight," explains Museum Director Hermann Arnhold. This principle applies not only to the new construction, but also to the historic parts of the building, where a spacious atrium is surrounded on two levels by an arcade. It was therefore necessary to design a new lighting solution for these officially protected arcades as part of the refurbishment.
Looking at how the arcades are currently used helped identify the key requirements. Flexibility and adaptability are extremely important factors for both temporary exhibitions and the correct presentation of a wide range of sculptures and objects. The integration of the lighting solution into the existing structures also played a major role, with visual disturbance caused by additional elements to be kept to an absolute minimum in the historical rooms. In addition, as the architecture offers visitors fine views across the central courtyard, it was necessary to find a suitable holistic lighting solution for both levels of the arcade.
After several test installations and close cooperation with the local listed buildings authority, lighting designer » Licht Kunst Licht AG from Bonn opted for » SUPERSYSTEM from Zumtobel. Given the combination of minimalist form, versatility and excellent lighting quality for sensitive artworks, this understated lighting system offered the perfect solution. When suspended centrally in line with the top of the columns, SUPERSYSTEM is the unifying light element that runs through the historic arcades.
SUPERSYSTEM performs several functions. It provides uniform indirect illumination of the vaulted areas for diffuse general lighting, carefully avoiding the transverse arches and only highlighting the vaults. In addition, fixed LED mini-spots enable direct lighting when required. The beam angle can be adapted for specific exhibitions by changing the lenses in the adjustable SUPERSYSTEM heads. Thanks to the flexibility of the light system, spotlights used elsewhere in the museum can also be mounted on the track to accentuate particular exhibits. The DALI lighting controls system works in combination with a portable control panel, making it easy for staff to independently regulate the direct and indirect lighting and individually adjust every group of LED mini-spots.

Fitted with a lens optic and opal cover, MIREL evolution is the perfect tool for refurbishing projects in office environments.
The stylistic idiom of MIREL evolution featuring an opal optic has been reduced even further, so that the luminaire now appears as a flat, level luminous panel. For the version fitted with an opal cover, a 3Dprotect® reflector is used, which not only ensures perfect direction of light but also protects the sensitive LED modules during installation. Due to the interplay of innovative LED technology and direction of light in MIREL evolution fitted with an opal cover, a luminaire efficiency factor of up to 123 lm/W is possible.
With its clear, unobtrusive and universally applicable design, the luminaire developed by STUDIO AMBROZUS is able to exploit its full potential in terms of lighting quality and energy efficiency. With a colour rendering index of Ra > 80, the louvre luminaire is particularly suitable for the various visual tasks to be performed in offices. MIREL evolution is available as a recessed, lay-in and surface-mounted luminaire in a square or linear version.

ONLITE RESCLITE HC is available in two models in compliance with EN 1838: as RESCLITE escape, for illuminating escape routes, and as RESCLITE antipanic, for room orientation in emergencies. The newly developed special lens of RESCLITE escape focusses the light along a lengthy, narrow strip. Thanks to high-performance LED modules and optimised optics, luminaire spacings of up to 22 metres can be achieved and the required minimum illuminance of one lux is ensured without any problems. Thus, energy-efficient illumination of escape routes in conformity with relevant standards is ensured.
On the other hand, antipanic lighting must achieve an illuminance level of at least 0.5 lux in order to provide orientation and allow people to safely find their way out of the building. Thanks to wide-angle and rotationally symmetrical light distribution, already one RESCLITE antipanic high ceiling luminaire is sufficient to uniformly illuminate an area of up to 290 square metres (at a mounting height of 16 m). With a high protection rating of IP65, the luminaires are protected against dust and water jets from any angle and hence also perfectly suited for use in harsh industrial environments. The luminaire can be installed directly on the ceiling or integrated into the TECTON continuous-row lighting system. It can be combined with the central CPS and eBox emergency lighting systems, which are available with DALI (NDA), Powerline (NSI) and circuit monitoring (NPS).
Additional support for emergency lighting designers
Zumtobel is also extending the services offered to emergency lighting designers. Not only is it possible to download the popular Zumtobel ONLITE RESCLITE app from the iTunes store, it is now also available on the Zumtobel website. Thus, access to the design tool is now possible from every PC, laptop, tablet or smartphone using any browser, independent of the device's operating system. On iPads and iPhones, the app can even be used offline and has become a valuable tool for emergency lighting designers. In just a few steps, the RESCLITE app is able to calculate the maximum spacing between emergency luminaires, depending on the mounting height.
Those who use mobile devices featuring different operating systems or laptops may download the tool from the Zumtobel homepage on the data sheet of every RESCLITE luminaire under the “Spacing” tab. There the mounting height of the luminaire can be adjusted by means of a slider. Subsequently, the maximum spacing between two luminaires is displayed.

Innovative special lighting solutions for two major contributions
The Biennale Architettura 2014 in Venice, curated by Rem Koolhaas, will open its doors on 07 June 2014. Until 23 November 2014, pioneering architectural ideas and concepts will be presented in the city with its lagoons and islands under the title of “fundamentals”. This year again, Zumtobel is involved as a sponsor, supporting two art projects by providing advice and lighting solutions developed specifically for this purpose. The Austrian lighting solutions provider has been a partner for central projects in the context of the most important exhibition of contemporary architecture since 2002.
“By supporting the Biennale di Venezia, Zumtobel makes a valuable and creative contribution to the discourse of light, architecture and art,” says Stefan von Terzi, Director Marketing at Zumtobel. “Our lighting solutions in the German Pavilion and the Central Pavilion also show how important it is to provide the right light for the installations and the architecture to present them to optimum effect.”
Fast motion presentation using LED
Koolhaas' motto of the exhibition in the Central Pavilion is “Elements of Architecture”, putting the focus on the fundamental components of a building such as the ceiling and the stairs. In order to enhance the experience and encourage discussion, Zumtobel has developed and implemented an integral lighting concept for the impressive domed area located at the centre of the pavilion. The main feature is a special LED solution that sets the ceiling fresco by the Italian painter Galileo Chini in the dome centre stage using various colour temperatures (TunableWhite technology). The installation, which is concealed behind a sill and integrated in a suspended ceiling at the same time, simulates the natural course of daylight. By means of various colour temperatures ranging from warm (3000K) to cool (7000K), the ceiling fresco is provided with fascinating aesthetic qualities, highlighting the polarity between nature and built-up space .
Zumtobel sets the stage for architecture installation in German Pavilion
For the exhibitions of the 29 National Pavilions at the Biennale, Koolhaas has made “Absorbing Modernity: 1914-2014” the overriding theme and has requested the countries to revert to their national architecture of the past 100 years. This year's curators of the German Pavilion, the Swiss-based German architects Alex Lehnerer and Savvas Ciriacidis, have responded to this request through an accessible room-to-room installation called “BUNGALOW GERMANIA”. This is an architectural assembly of two buildings historically significant to Germans: the first is the German Pavilion in Venice itself, built in 1912, converted in 1938 and 1964. The second building is the Chancellor's Bungalow in Bonn by Sep Ruf, built in 1964. These two buildings represent two eras in German history, two political systems and two architectural idioms.
The installation by architects Lehnerer and Ciriacidis is a 1:1 replica of parts of the Bungalow integrating the architecture of the Pavilion. A “third room” is eventually created that links the histories, moments, eras and locations of the two buildings, allowing for new associations in terms of form and use of architecture and the related German history. The unique architecture of this project is enhanced by a special lighting solution provided by Zumtobel, strongly emphasising the concept of the two artists.

Visual highlighting of individual product groups ensures attractive product presentation and makes it easier for shoppers to find their way within the store. Moreover, the freshness of the food displayed is emphasised by targeted use of specific colour spectrums. For illuminating the fresh food department and the wine racks, Zumtobel has opted for efficient high-performance LED spotlights: swivelling VIVO LED “Tunable Food” spotlights and CARDAN “Tunable Food” recessed luminaires provide high-precision accent lighting in order to present sensitive foodstuffs such as meat and fish to optimum effect. Zumtobel's “Tunable Food” LED concept allows product-specific illumination and effective presentation of goods. Thanks to innovative technology, the perfect colour temperature can be adjusted directly at the spotlight, with ten colour settings already pre-programmed. This ensures an authentic look of the products with perfectly uniform light distribution. Furthermore, IR- and UV-free lighting provided by LED luminaires is gentle on fresh food and reduces harmful thermal output, ensuing that fruit and vegetables remain luscious and meats stay fresh longer.
Baked goods, the wines on offer and the cheese counter are presented to optimum effect by the VIVO LED and CARDAN LED spotlights featuring built-in “Stable White” technology in a colour temperature of 3000 K. The market hall's uniform ambient lighting is provided by TECTON, a flexible continuous-row LED system integrating batten luminaires, light sources and reflectors within its trunking. This allows for easy installation and reduces maintenance costs. TECTON has been mainly installed as individual light ribbons in the wooden ceiling and between the shelves, which allows the luminaires to blend decoratively into the interior, underlining the character of the room.
Another benefit of the LED lighting solution fitted at the Spar market in Budapest is its high energy-saving potential. By using LED luminaires, at least 40 percent of energy can be saved, as compared to a conventional luminaire system. In addition, LED luminaires by Zumtobel boast a service life of at least 50,000 hours – the LED lighting solution therefore requires virtually no maintenance.

A second installation sponsored by Zumtobel can be found on the square in front of the Deutsche Bank Towers. Consisting of 576 prism poles made of glass, the Twinkle Twinkle installation is a transparent and dynamic structure that reflects daylight and its surroundings, creating an enthralling experience for visitors. Daylight is refracted by the prism poles, which produce lighting-like reflections fanning out into a fascinating colour spectrum.
In daylight, the sculpture appears scarcely palpable; at night, 18 Elevo RGB DMX façade luminaires set the four-metre concentric structure aglow. The special lighting presentation creates a dramatic effect, which is enhanced by background music. Twinkle Twinkle is a project by Glasbau-Hahn GmbH, NE-AR Nixdorff Etchegorry – Architecture Research, lichtundsoehne – lighting & visual design, O-S-D – office for structural design and studioheyhey – visual communication.
At this year's light+building, Zumtobel – as an expert in the field of interior lighting for commercial purposes – will also present an extensive product range for façade & architecture applications. Providing smart, resource-conserving illumination for façades based on cutting-edge LED technology, Zumtobel meets both functional and aesthetic requirements.

Individual and adaptable lighting solutions in times of change
Through perfect interaction of all components, from the design via all electronic elements through to controls, the new luminaires exploit the possibilities offered by today's LED technology to the full. In this context, the claim to offer lighting quality for people in harmony with the environment acquires a new meaning: Zumtobel presents intelligent lighting solutions that have reached an even higher and more individual degree of personalisation. In the process, the Austrian luminaire manufacturer focuses on the requirements of customers and the needs of users within the scope of various applications. Zumtobel sees itself as a partner supporting companies in working the switches for the future. Light is turned into a success factor whenever the point is to improve energy efficiency, to reduce CO2 emissions and operating costs, to set the stage for brand universes and art collections, or to create working and living environments that have a positive impact on people's well-being. The knowledge about light and its effect on people has always been the foundation of the Zumtobel brand and of its lighting solutions.
Among other things, two new studies designed for the Retail and Office applications are going to represent points of focus at this year's light+building. The results of both studies constitute an important basis for the development of new innovative lighting solutions.
Zumtobel Limbic® Lighting: target group-adequate lighting concepts for Shop & Retail applications
Research in the field of neuroscience has shown that 90% of purchasing decisions made at the POS take place in our unconscious mind. In a laboratory study, Zumtobel, together with Gruppe Nymphenburg, managed to empirically capture the subconscious reactions to a variety of lighting scenarios. The lighting preferences of seven different groups of customers were analysed using a neuropsychological target group model. For the first time ever, the results put brands in a position to use optimised lighting concepts for their respective target groups. Accordingly, »Zumtobel Limbic® Lighting not only presents goods to optimal effect, but the light is also adjusted to match the customers' preferences. In this way, their sense of well-being is enhanced and will consequently also increase the time they spend in a shop.
With the aim to allow for even more differentiated lighting at the POS, Zumtobel has extended its product range in the Retail sphere, based on these research findings. Modular spotlight systems such as INTRO, including innovative liteCarve® reflector technology, reduce complexity, at the same time offering an optimally customisable lighting solution for the different areas, from shop windows via shelves and recesses through to special displays. By means of innovative TrueGamutRendering fashion (TGRfashion) LED technology, white but also deep shades of colour are given entirely new brilliance and quality, offering customers unprecedented authenticity of product presentation.
User study on lighting quality in offices
By conducting the largest user study in the company's history, Zumtobel, in collaboration with Fraunhofer IAO, has obtained valuable insights into the lighting quality perceived in offices. The interim analysis of the long-term study »http://www.zumtobel.web-erhebung.de/english/ already shows that focusing on the user affords new findings that will necessarily lead to a rethinking of lighting design and lighting management in office environments. The need for solutions based on the individual needs of the users is only insufficiently satisfied today.
• Almost 82 per cent of survey participants prefer a combined lighting solution including direct and indirect components. In fact, however, only 38 per cent have such a lighting solution at their workplace.
• The study provides similarly significant results in terms of the assessment of the lighting quality of different light sources: LEDs are most favourably rated by a majority of survey participants. Actually, however, only 10 per cent of study participants state that LED luminaires are in place in their offices.
• As regards the preferences for colour temperatures in the office, these are distributed heterogeneously between 3000 K and 7000 K. However, the users' preference for the range between 4000 K an 5000 K is by far the most marked.
• Close on 57 per cent of all employees are not able to adjust their office lighting to their individual needs or variable work settings, or only to a limited extent.
• Overall, more than 60 per cent of survey participants prefer illuminance levels of 800 lux or higher. Based on this finding, illuminance levels should be designed to exceed the standard of 500 lux in future.
Restricted user access and a lack of options for the adjustment of colour temperature and illuminance cause significantly poorer assessments of lighting quality and well-being by the users. On the basis of these research findings, Zumtobel has adjusted and extended its product range for office applications.
Today already, the SEQUENCE LED luminaire featuring advancedOptics technology and the LIGHT FIELDS luminaire range featuring Tunable White technology are demonstrating how the manifold requirements of employees can be met by adaptable, pinpoint task area lighting.
Within the scope of such customisable lighting, lighting control plays a key role. In order to break new ground in this respect, Zumtobel has cooperated with partners like IBM and interface experts. The result is the innovative LITECOM lighting management system that represents a milestone in the future of building management. LITECOM not only features easy installation and intuitive handling via apps; it also is an open system, additionally creating a high degree of customisability and flexibility.
Zumtobel. The light.
A global user study investigating lighting quality in offices launched by Zumtobel Research and the Fraunhofer IAO is producing important findings: even just a few months after this long-term study began, it is becoming apparent that most of the office employees who have been surveyed so far prefer individually controllable, variable-colour temperature LED lighting with a direct/indirect component and illuminance in excess of 800 lx. It is also clear, however, that solutions that cater for these preferences are extremely rare. This underscores the huge need for individually controllable LED lighting solutions in the workplace, solutions that provide appropriate lighting to meet any requirement while delivering optimum lighting quality and energy efficiency.
• 82.5% of those surveyed prefer direct/indirect lighting
• 60% of office employees prefer illuminance in excess of 800 lx, this preference becoming less marked with increasing age
• Even in summer months, the need for artificial lighting is high
• 57.4% of those surveyed have no or only limited ability to influence their lighting situation in order to adjust it to their needs
• Colour temperature preferences differ widely, ranging from 3000 to 6000 K, with a significant cluster around 4000 and 5000 K
• 2,643 participants from Europe, Asia, Australia and the USA have been participating in the study since November
Numerous directives, standards and assessment criteria have to be taken into account when designing lighting solutions for office workstations. Other important factors include individual user preferences, task-related requirements and employees' emotional well-being. In order to throw light on all these aspects, Zumtobel, together with the Fraunhofer Institute for Industrial Engineering (IAO), has developed and conducted a long-term study on a global scale: under the title "The Light. Global User Study on Lighting Quality Perceived in Offices"* , 2,643** office employees from Europe have already assessed the lighting situation in their personal work environment with the aid of a multilingual online survey form since November 2013. The aim of this long-term study, which will run until the end of 2014, is to allow as many different users as possible to assess perceived and expected lighting quality in a variety of office situations.
This is creating a highly informative, global map of light that will provide information indicating which settings are best suited to particular individuals in specific situations. Zumtobel will use the study findings to build this knowledge of user preferences and behaviour into its product development work. LIGHT FIELDS evolution tunableWhite and SEQUENCE are direct fruits of this user-focused process. It is making it possible to anticipate what innovative lighting solutions will have to be able to do for employees in offices in the future. According to Fraunhofer IAO data, this Zumtobel study is already one of the most successful ever investigations of this topic in terms of the numbers of users who have participated in it. The fact that over 60% of those surveyed state that they want to be informed of the research findings shows how interested users are in this subject.
Office employees prefer direct/indirect light and high illuminance
One of the most important interim results is the clear preference expressed by study participants for direct/indirect lighting and illuminance higher than that specified in the relevant standard. 61.6% of those surveyed only have direct or indirect lighting in their office, a situation that is preferred by only 17.5% of them. In contrast, 82.5% of those surveyed prefer direct/indirect lighting. Most users also prefer lighting can be flexibly adjusted to suit various tasks.
The study is also yielding the first noteworthy findings indicating clear preferences when it comes to illuminance: 500 and 800 lx in the task area are perceived as being the most pleasant illuminance levels. About 60% of those surveyed nevertheless expressly want illuminance levels higher than 800 lx – a level significantly higher than the mandatory 500 lx stipulated in the relevant legal standard.
Strong demand for individually adjustable artificial lighting
Participants' preferences regarding colour temperature have provided an interesting interim result: across all age groups, genders and nationalities, it was established that user preferences when it comes to colour temperature range from 3000 K to 6000 K, with a clearly marked majority preference for 4000 K and 5000 K scenarios. Continuously colour-temperature adjustable LED luminaires cater for these individual needs the most effectively. After more in-depth analysis it is also striking that there is also relatively high demand for artificial lighting in summer, not just in dark winter months. 60% of those surveyed use more than seven hours of artificial lighting in winter, and 33% still use this much artificial lighting even in summer. One reason for this might be the fact that 61.2% of those surveyed do not sit in the vicinity of a window and therefore enjoy relatively little natural light. This makes it clear how great the need for artificial lighting is, and emphasises how important it is to coordinate daylight and artificial lighting. It also makes the size of the comparative potential energy savings that can be achieved by using an intelligent, daylight-based LED lighting solution quite clear. The study has also shown that 57.4% of those surveyed, i.e. more than half, have no or only limited ability to influence their lighting situation in order to adjust it to their needs.
Analysis of these interim results makes it obvious that innovative lighting solutions for office environments must be controllable in a differentiated, intelligent and individual manner. This way, lighting can be adjusted straightforwardly to meet requirements in any task area in order to deliver the right light for each visual task and every situation. Combined with daylight, an intelligent lighting solution therefore promotes both employees' well-being and health. And it also makes a considerable contribution to energy efficiency. "This study is giving us a differentiated picture of modern office architecture and the needs of employees in businesses all over the world" says Christoph Mathis, Director of Global Application and Product Management. "The results will be fed into our product development work worldwide and really help us achieve our goal, the best light for people and the environment."

Interface designers and application experts have been involved in this development work from the beginning. For users, LITECOM delivers simple configuring, intuitive user prompting and high lev-els of flexibility. All of this is made possible thanks to the synthesis of controller, touch panel and software within one system: LITECOM is an open lighting management platform that is not tied to specific systems. Instead, the solution offers a modular, interactive automation model that supports the integration of an extremely wide range of field bus architectures. This openness is not just con-fined to bus systems, it also extends to other control infrastructures and future automation scenar-ios. HTML5 is used exclusively as the interface language for the graphical user interface. This means that the user interface can be accessed via any laptop, tablet or suitable smartphone. The system's modular software is entirely written in Java and can therefore run under Windows as well as Linux operating systems, for instance.
LITECOM operation via a plug-inThe lighting management system's variably configured plug-ins, which are built as apps, mean that now there are hardly any limits when it comes to individual pref-erences. From making simple colour changes to the user interface, daylight-based control and dynamic lighting control through to complex emergency lighting control programs, LITECOM is able to meet any individual requirements users may have: every customer can compile an individual app package, depending on room functions and user demands. Based on the predefined initial settings, all functions can be controlled and adjusted as required.
It is also possible to customise individual apps especially to the functions of a particular luminaire. For instance, the SEQUENCE office luminaire can be controlled and adjusted using an app spe-cially developed for this purpose, in order to implement a perfect lighting solution tailor-made to the user's requirements.
With a suitable app, LITECOM can also be used as a central monitoring unit for emergency lighting systems with separate battery supply. This way, one system is sufficient to control and monitor both the ambient lighting and the emergency lighting system without any extra effort.
Thanks to its dynamic design, this lighting management system is equipped to cope with future requirements. Additional automation services can be added simply as plug-ins thanks to three spe-cial Application Programming Interfaces (API). This means that the functionality of the system can be enhanced at any time beyond the scope of the Zumtobel services that are initially supplied with it. It isn't just Zumtobel that can constantly expand the system's functional repertoire; thanks to open interfaces, users can program their own apps and use them in the system. Hence, customer-specific demands can be met with little effort, either directly by the users themselves or as a ser-vice for the customer.
Intelligent control for extra flexibility
LITECOM is built to cope with both current and future building management system technologies. The solution encompasses the entire physical structure of the building and maps all the relevant technical facilities appropriately. Rooms or parts of rooms can be combined to form floor levels or other subdivisions of a building in order to structure all the luminaires, sensors and controls of a building, including their mutual interactions, in a flexible manner. Another sophisticated LITECOM feature: lighting management data can be integrated freely and consistently into other building au-tomation systems, something that, until now, has always been very time consuming. This lighting management is therefore suitable for relatively small solutions in SMEs as well as for complex light-ing scenarios in large companies.
Optimising energy consumption
Zumtobel's new Lighting Performance Platform also offers cus-tomers another benefit: this online platform enables customers to compare the consumption data of buildings and rooms at a glance, thus tapping into potential energy savings. This monitoring tool is perfectly matched to lighting management systems such as LITECOM; it monitors energy con-sumption within a company and shows how to achieve optimum energy efficiency using lighting management. Buildings, floor levels, rooms or even individual workstations can be addressed and conveniently presented in sunburst diagrams, so that their energy consumption can be optimised.

Sequence has been designed as a pendant or surface-mounted luminaire and consists of 8 or, optionally, 14 side-by-side module units of identical design, each with 6 x 3 centrally located LED lighting points. Special lens technology with symmetrical or asymmetrical distribution characteris-tics in front of each of the 18 central LEDs ensures perfectly directed task lighting with good glare control. This prevents annoying reflections on screens, tablets or smartphones. At the same time, thanks to an opal cover frame, the 24 outer LEDs provide diffuse ambient light and altogether softer light distribution.
Individually controllable modules
Grouped together in three logical sets (each consisting of 4 outer modules and 6 inner modules), the individual modules, as well as the indirect light component, are individually controllable. Each set has a DALI address. The electronic control system, specially developed for Sequence, ensures gentle transitions between modules, despite the fact that there are only four addresses for 14 mod-ules. This makes adaptive lighting possible.
Besides this exceptional performance feature, Sequence, thanks to its flat aluminium housing, boasts an especially slim shape that blends perfectly into any interior design. The luminaire's so-phisticated design – all its electronic components are almost invisibly enclosed in a slightly raised area on the top of the luminaire unit – ensures a delicate appearance.
Sequence is available with a colour temperature of 3000 K (warm) and 4000 K (intermediate). Zumtobel supplies this luminaire in lengths of 1200 mm (6 LED modules) or 2100 mm (14 LED modules).

The Bristol-based “Lighting Services” worked closely with the client to deliver a lighting solution which has received acclaim "English Heritage is delighted with the scholarly programme of restoration and conservation work at the Reform and considers that its outstanding interiors are greatly enhanced by the lighting scheme adopted". Zumtobel was chosen as the appropriate partner to provide the concept led technologically advanced lighting and control systems. Product design fulfilled the requirements in terms of efficiency, sustainability and flexibility which played a role in delivering the final outcome.
Based on Zumtobel`s intelligent Luxmate Litenet lighting management system, ‘Lighting Services’ were able to develop an innovative lighting concept that provided adaptable multiple DALI LED spotlights which cross washed 18 listed portraits and once dark and out of sight, the splendid coffered ceilings, swags and pilaster capitals are now vibrant and alive. The columns are set in relief providing a wonderful overall balanced visual effect to what is in essence a fabulous stage set. Thanks to the system's compatibility, the lighting solution can be adjusted as required and can also be extended to incorporate other areas and fittings.
Daylight-based control increases comfort and efficiency
Since the building is used 24/7, potential energy savings had to be identified and realised to optimum extent. This sustainable lighting solution is based on the perfect interplay of state-of-the-art LED technology and innovative luminaires with intelligent lighting management as its centrepiece: the Luxmate Litenet lighting management system combines complex system features such as use of daylight, presence detection, integration of emergency lighting, and predefined room profiles in one central unit that is easy to operate. The external daylight sensor installed on the roof continuously monitors incoming daylight, thus optimising the use of daylight. In every room, just the quantity of artificial light is added that is required to achieve optimum lighting conditions.
In addition, Luxmate Litenet provides a high degree of flexibility, which was the decisive factor for its use at the Reform Club. As the lighting system will be refurbished step by step in other areas and rooms as well, the client requires the system to be easily extendable in the future. Using pre-programmed scenarios, Luxmate Litenet also provides the opportunity to easily and conveniently create appropriate atmospheres for a variety of social gatherings and other events in the areas designated for this purpose.
As the heritage requirements dictated that the light source should not be visible for the most part, the minimalist Supersystem LED lighting system was used in all areas, both on the ground floor and the first floor. Thanks to its pared-down design, Supersystem blends unobtrusively into the architecture, enhancing it to optimum effect. The high-power LED spots cannot fail to impress on account of their modularity, since lighting inserts for direct and indirect lighting can be flexibly placed next to each other within one module, which allows them to tackle a variety of different lighting tasks easily. In the atrium, the lighting solution is complemented by DALI LED Decoline and Discus LED spotlights. They set the lighting stage for the impressive “sun-burner”, an oversized historic gas lantern formerly used for illumination and heating.
With the lighting required – both by the Client’s concept and heritage constraints – to be in relatively inaccessible locations the life and location of components and the cost of their maintenance and component replacement was a key factor. The traditional lighting had required a visual manual check on failed bulbs and their regular and frequent replacement.
About the Reform Club
The impetus for the establishment of the Reform Club was the Great Reform Act of 1932. The Club is in the heart of London’s Clubland. Established in 1836 by the Whigs and the Radicals the club later became the home of the Liberal party. It is now without any affiliations to any political party. The Club is well respected worldwide and is at the hub of an international membership and provides a significant and varied intellectually challenging programme. The link with the past enhanced by the magnificent architecture of Sir Charles Barry provides a brilliant and inspiring stage set in which to host the intellectual and social life of the Club.

Zumtobel. The Light.
In a laboratory study conducted by Zumtobel and Gruppe Nymphenburg it has been possible for the first time to measure people's affective responses to various lighting scenarios in shops on an empirical basis. In the process, the lighting preferences of seven different groups of customers were analysed using a neuropsychological target group model. The findings of this study will help to develop lighting concepts for retail, to present goods perfectly and to increase the customers' sense of well-being, thus making them stay in the shop longer.
The most recent research in the area of neurosciences has shown that more than 80 % of buying decisions at the point of sale (POS) are made unconsciously, mainly depending on influences addressing people's emotions. Perfect lighting plays a major role in this context: customers do not only perceive the goods visually, but will be touched by an attractive lighting scenario at the emotional level. However, the effects of light have so far been evaluated only by means of various questioning techniques, without taking the decisive aspect of the unconscious into account. For that reason, Zumtobel Research jointly with Gruppe Nymphenburg, a Munich-based consultancy and market research institute, initiated a laboratory study in order make the emotional effects of light on customers measurable empirically, recording their physiological responses. “Light has a major unconscious impact on people”, explains Dr. Hans-Georg Häusel of Gruppe Nymphenburg. “Therefore, those who wish to collect data that can be empirically measured and also challenged have to deal with the unconscious, carrying out measurements at the place where people's emotional responses originate.”
The “Limbic Model”: characterisation by personalities
For the laboratory study, the researchers used the “Limbic Model” developed by Gruppe Nympenburg, which focuses on the complex emotional personality structures of consumers. The sociodemographic data of the 48 subjects involved where therefore negligible for the purpose of the study. Instead, the subjects were assigned to seven different personality types, the “Limbic Types”, using a questionnaire. These included the “Bon vivants”, the “Hedonists”, the “Adventurers”, the “Performers”, the “Disciplinarians”, the “Traditionalists”, and the “Harmonisers”. The objective of the research project was to find out how these seven groups respond to various lighting scenarios at the POS. For this purpose, a new method developed by Gruppe Nymphenburg was used, the “Limbic Emotional Assessment” (LEA). Using this method, even the most minor physical responses can be measured.
In the laboratory experiment, the researchers placed the male and female subjects between 19 and 62 years of age in front of a 3D shop simulation installed in a research lab, which displayed fashion items illuminated in various different ways. The subjects successively looked at 20 different lighting scenarios with various ambient and accent lighting features, colour temperatures, contrasts and light quantities. While doing so, their unconscious physical reactions, including brain waves and cardiac activity, were empirically measured. Based on the psychophysiological data collected, it was possible to clearly establish which of the lighting scenarios' parameters triggered positive or negative emotions, stimulation or relaxation in specific target groups. In the process, it was found that even minor changes between the individual lighting scenarios triggered different responses in the subjects.
On the results
The findings obtained clearly show that there is an optimal way to address each individual target group. It has also turned out that there is no single lighting scenario which has the same markedly positive impact on all “Limbic Types”. There are, however, individual lighting profiles which several types respond positively to. Three main groups were identified, each with similar requirements as to lighting solutions: the first group, BALANCE (Harmonisers, Traditionalists and Bon vivants), responded particularly positively to moderate accent lighting. The second group, STIMULANCE (Hedonists, Adventurers), responded most positively to lighting scenes with relatively strong contrasts, created by accent lighting and a variety of different spots. Group three, DOMINANCE (Performers, Disciplinarians), responded sensitively to unbalanced lighting concepts and can best be loaded with positive emotions through balanced, moderate effects. However, narrow-beam lighting with extreme contrasts triggered negative emotions in this group.
Dr. Hans-Georg Häusel summarises: “Again and again we find that the importance of lighting at the POS is dramatically underestimated. Instead, the focus is on fancy packaging and shop design. But actually, the goods on display will only touch people's emotions if they are set centre-stage through light. Even the affective signals emanated by the shop itself are strongly influenced by light.”
For only if customers feel at ease inside a shop and perceive the lighting scene as attractive will they be motivated to stay for a while. Ultimately, this means that customers will have more time to notice the products and brands in a shop and to buy them. “By combining neuromarketing with our lighting expertise, we can effectively implement a new way of addressing our target groups already at the stage of lighting design, for the benefit of our customers”, says Peter Kovacs of Zumtobel. “This helps us create lighting scenarios for specific brands and target groups that accurately meet the needs of customers in shops and retail areas.”
On the research method:
The Limbic Emotional Assessment (LEA) research method, which has been developed by Gruppe Nymphenburg, is based on methods used in neurosciences as well as psychophysiology. The latter discipline is concerned with the relationship between brain activity and the related physical responses. In combination with Limbic, a brand and target group navigation model tried and tested in practical applications, LEA allows for a distinction according to specific target groups. In doing so, the scientifically tested LEA method combines five different parameters that capture even the tiniest of physical reactions. From brain waves and skin conductance through to cardiac activity, numerous physical reactions of customers are measured to draw conclusions on their emotional state.

In a laboratory study conducted by Zumtobel and Gruppe Nymphenburg it has been possible to measure people's affective responses to various lighting scenarios in shops on an empirical basis. The findings of this study will help to develop lighting concepts for retail, to present goods perfectly and to increase the customers' sense of well-being, thus making them stay in the shop longer. Building on these research findings, Zumtobel is extending its product portfolio with LED lighting solutions suitable for various shop scenarios.
Light is an indispensable tool for presenting brands and products effectively in retail settings. In addition to brand-appropriate, authentic presentation, energy efficiency also plays a crucial role when it comes to implementing shop and retail lighting concepts. The Intro modular lighting system incorporates different types of luminaires that use the very latest LED technology, and offers retailers an efficient lighting solution that can be fully customised to cater for various areas of a store: from shop windows, shelves and recesses through to activity spaces – Intro can be used in any area.
liteCarve® - first vertical flood-spot made possible by new reflector technology
liteCarve ® reflector technology developed by Zumtobel offers extreme design precision. This freeform reflector (patent pending) allows extremely precise, well-balanced rectangular light distribution, right up to the outermost peripheries. Mounted in front of a single LED (CoB) point light source, the reflector directs 100% of the light indirectly in a targeted manner and makes it possible to bring vertical surfaces alive: this allows uniform, efficient illumination, not only of displays, but also shelves, large posters, recesses and specific wall areas. This system spotlight has established a completely new product category – the vertical flood-spot or vertical wallwasher. The system can also be fitted with other gimbal-mounted spotlights, depending on the particular lighting task in hand. This means that merchandise in shops is superbly presented to customers – attention is focused on the areas that are to be highlighted
Separate lighting modules and installation frames allow designers and architects plenty of creative scope: a large number of possible combinations on the ceiling underscore Intro's great flexibility. Zumtobel offers the system in single, double and triple units, as well as in lighting channel form. All the spotlight modules can be fitted with different front ring versions that are available in white, black, matt silver, chrome and copper as required. There are virtually infinite customisation options. All RAL colour hues are possible as special versions. Intro's modular design and the possibility of integrating various different spotlights provide a lighting solution that is tailor-made for efficient LED technology, offers plenty of customisation options, and specifically caters for setting the perfect stage for brands. This enables retailers to implement brand scenarios that are consistently configured to address a particular target group.
TrueGamutRendering (TGR) technology – A new level of quality for fashion lighting
White light plays a really significant role in achieving authentic retail presentation because light is the most important component when it comes to perceiving and evaluating goods. TGRfashion technology has enabled Zumtobel to achieve new levels of shop lighting quality. It lends a fresh quality to white, light but also to a brilliant appearance of bright colours. TGRfashion displays white colours with particular purity, and the LED spotlight emphasises and differentiates the various properties of different materials. At the same time, this technology makes it possible to present colours really vividly. This technology is initially available in the size M IYON LED spotlight, which provides a luminous flux of more than 2000 lm.
FACTOR: reduced complexity and high lighting quality
Zumtobel has added Factor, a modular LED spotlight, to its product range for shops and retail areas. Factor combines reduced complexity with great lighting quality and is available in two design versions: its conical or cylindrical housing provides plenty of creative scope for implementing retail lighting solutions. To ensure flexibility, it is installed on a 3-phase track or on Metrum, Zumtobel's simple continuous-row system: Factor spotlights can be repositioned without fuss if a shop needs to be redesigned. Factor is optionally available in a warm (3000K) or intermediate white (4000K) colour temperature to ensure presentation that matches specific merchandise.
The well-devised lighting concept is based above all on highly efficient Arcos Xpert LED spotlights. As the colour temperature can be selected directly on the spotlight and replaceable optics can be individually adjusted, they provide the versatility and flexibility required by the exhibits' different materials. In order to enhance the sculptures' three-dimensionality and avoid hard shadows, soft outline lenses and accent lighting directed from various positions were used, accompanied by an excellent colour rendering index of Ra 94 as well as UV-free and IR-free LED light that is gentle on the exhibits. Moreover, the luminaires recede into the background thanks to their purist design, yielding the stage to the exhibits.
While the exhibits in the exhibition rooms are mainly illuminated by Arcos Xpert spotlights, highly efficient Panos Infinity LED downlights as well as the Tecton continuous-row lighting system and Linaria light lines are used in the side rooms. The Veneranda Fabbrica (Venerable Factory) was established more than 600 years ago to supervise the construction of Milan Cathedral. Today, the organisation deals mainly with maintenance, preservation and restoration of the church. One of its well-kept treasures is the Archive situated in the building opposite the cathedral, in Piazza Duomo 20, displaying more than 500,000 historical testimonies and documents dating back as far as to the year 1145. Perluce recessed luminaires ensure gentle illumination of photosensitive documents while at the same time providing ideal lighting conditions for the staff's work.
Thanks to this interplay of flexibility and lighting quality, taking conservational aspects into account as well as ensuring high energy efficiency, the lighting solution could not fail to impress both clients and architects. In the course of intensive design work and based on several models, they managed to jointly develop an individual lighting concept resulting in fascinating brilliance.
