After many successful years as the managingdirector of Siteco,Dr. Peter H. Emmert hasdeparted from the company. His successor isANDREAS SCHÜTTE (42),who in his lastfunction was globally responsible for the rollerplant activities of Hydro Aluminium ASA.Andreas Schütte has a wealth of internationalexperience within the manufacturing sector.We asked him about his future plans.

Herr Schütte,you worked previously with analuminium manufacturer. Now you havebecome involved with light.What do you findso appealing here?Light fascinates me in the first instance as amedium for designing. With its capability forhighlighting contours, emphasising surfacesand creating atmospheres it has thepossibility to bring architecture and interiordesign to its full worth. No less interesting forme are the psychological, biological andergonomic aspects of light. It is just simply a

very facetted sector with many possibilities,of course also of a technical nature. By theway, questions related to the lighting industrywere already familiar to me in my time asmanager within the aluminium sector. Afterall, many luminaire housings are made ofaluminium.After the first 100 days as managing director:What do you find good about Siteco and whatwould you like to improve:The Siteco brand has an excellent productportfolio, and in some application segmentswe are technology leaders, for example lightguidance with Eldacon, the fresnel reflector orother innovations in the area of secondaryreflector technology. And at the moment wehave some spectacular large-scale projectsthat are envied by the competion, such as theBarajas Airport in Madrid or the Allianz Arenain München. Above all I like the fact thatSiteco is not just a sober production plant butan extremely dynamic corporation that hasclever people within all areas ofresponsibility. We will certainly have tochange the cost structure somewhat, andinternal proceedures will need to be

optimised. Concerning the manufacturing, itwill be important to look beyond the end ofour nose and gather stimulae form othersectors. Which means that we don't need tohave invented everything that we produceourselves. We should be completelyunemotional and dogmatic in that respect.Which strategic targets will you be followingfor the company?Traditionally the company concentrates verymuch on distribution within the electricalwholesale sector. Siteco has only presenteditself as an independent brand in the marketsince 2001 and now increasingly addressesarchitects and lighting consulatants. Withinthis target group we gain a higher profile.Which means we shall be accentuating ourproduct portfolio. We do not want tomanufacture everything that the marketneeds, but merely be active in those areaswhere we can distinguish ourselves.

S U N R I S E I N T H E B U S I N E S S C L A S SUntil now, jetlag belonged to jetting as much as a hangover belongs tothe excessive consumption of alcohol. But now developers from theNuremberg company Diehl Luftfahrt Elektronik (DLE) have come up witha solution. 'Mood lighting' is the name of their recipe for acclimatisingproblems of the body when flying through the time zones.What's behindit is a computer-controlled lighting system in aeroplane cabins that withthe help of coloured light emitting diodes (LED's) can simulate naturaldaylight progressions. When the LED sun rises the passenger perks up,when it sets, he nods off - that's the idea at least.The lighting scenes alsowork with colour moods - orange and red tones activate the passengersto deboard, and the system can accentuate single cabin areas such asbars or emergency exits. Convince yourself about the effectiveness of'mood lighting' - for example as a passenger in the new Airbus A380. <--

A S A L I G H T W E N T O N I N S C I E N C EExactly 300 years ago, Isaac Newton's Opticks appeared, his epoch-making work about light and colours. Thebriton was the first to prove that white light is created from the spectral colours,and with his prism experimentshe established a new branch of research in physics - optics. The new theory found many enemies. One of themost prominent was Johann Wolfgang von Goethe, whose theory of colours appeared roughly 100 years afterthe Opticks. Goethe's insights, for example his colour circle, are valid even today. A paradox? Not at all. Goethewas interested in a 'sensual' effect of colours, i.e. their perception, whereas Newton was interested in purescience. <--

Its curved roof bears resemblance to a bedouin tent that raisesitself with a swing into the air. When one approaches the pavilion, heavymetal comes into play: steel columns, supports, grids, bridges - the wholearsenal of ambitious high-tech architecture. The synthesis of magic andtechnology that characterises the work of the architects Salem Al-Marzouk and Sabah abu Hama passes perfectly to the noble cars that arefor sale here. And the lighting too. In the presentation area, secondaryreflector systems cast glare-free light onto sleek coachwork, and in otherareas Lunis Downlights unfold their potential as magical starryfirmaments on high or as technoid dispensers of light.

Everyone knows reflective warning vests, but self-illuminating blouses,miniskirts, wedding dresses? Luminex, a cooperation between the swisstextile manufacturer Stabio Textile and the italian electronic specialistsCaen now turns fiction into fact. Their novel fabric contains lighttransmitting fibres - coloured light diodes controlled by integratedelecronics supply the light. The electricity comes from the socket or frombatteries. According to the manufacturer the textile can be handlednormally. But whether the fashion industry really needs glittering flaredtrousers or glowing red tops is an open question. The automotiveindustry though has already shown interest: Luminex is working onprototypes for car interiors.www.luminex.it

Odessa was always a prosperous city. It was established as a militaryharbour in 1794 by the russian tsarina Katharina II, and the first mayor,the frenchman Emmanuel de Richelieu, set himself an ambitious aim: thecity should be more beautiful than Paris.Within a short space of time thepearl of the Black Sea could compete with St. Petersburg, the grandmetropolis in the north of the empire.Royalty,aristocracy and artists spenttheir summer holidays there or stayed - like Puschkin - for years.Even todaythe charming, cosmopolitan harbour-city attracts tourists and investorsfrom all over the world. The 90's saw a construction boom that stillcontinues. A current example of this is the sports palace finished thissummer in Yuzhniy,an industrial suburb of Odessa.The complex,designed

by the architect Yuri Serjogin, consists not only of a sports hall but also ahotel, an open-air stage, a childrens' playing area and a park. In the centreof the sports palace is the multi-purpose hall that can be adapted forvarious sports disciplines and offers seating for 2000 spectators. Becausethe arena will be the location of international championships, the highestinternational standards were set for the lighting installations. Siteco notonly supplied floodlights and projectors for the playing areas but alsosecondary reflector systems for two atriums and solutions for buildingvicinity lighting. <--

Recently the swedish telecommunications company Teracom moved intotheir new headquarters in Stockholm, an office building from the 70'smodernised by Tema Arkitekter. The spaces have been layouted for 300people, carrying out their work primarily in open-plan and group offices.Additionally there are conference rooms, event rooms and cafeterias.Ejhed Light and Design from Stockholm were responsible for the lightingdesign. Apart from accent lighting in certain areas (shelves, fronts), theQuadrature plays the main role. The choice of this luminaire was basedmainly upon the high standards of the customer regarding flexibility ofworkspace lighting. The Quadrature's glare-free light allows for anypossibility of luminaire arrangement within the working area - theworkspaces can be rearranged without the need to change the lighting.Siteco distributors Annell Ljus+Form delivered luminaires for bothrecessed and suspended mounting. <--

The Taipei 101 Tower completed at the end of 2004 isa superlative construction: the highest skyscraper inthe world with 508 metres also has the highest usablestorey (438m), the fastest elevator (1010 metres perminute) and the heaviest pendulum to counter-balance oscillations from earthquakes or typhoons,with 660 tons. The name of the tower located in thenortheast of Taiwan's capital city Taipeh is taken fromthe number of its storeys.The building has been constructed on a site that isscarcely suitable for skyscrapers. While Manhattenstands upon a granite platform, Taipeh Tower sits on557 struts that sink into the soft ground up to 80mbelow the surface. For even more stability the buildingis constructed with so-called 'mega-struts' thatcombine all storeys via giant crossbars. In order toprotect the building against typhoons and similardangers the architects did not only depend upon steel,concrete and static calculations. Feng Shui andtalismans also play a role. For example they gave thesteel girders in the lower floors the form of luck-bringing dragon skeletons. Cylindrical elements onthe fenestration take their form from dragons' headsand the stone drums of chinese temples. The wholearchitectural construction resembles a giant bambooshoot, which in Taiwan is synonymous with luck andwealth. In order that the beauty of this organic towerof light can be seen during the night, the facade is ofcourse illuminated - with projectors from Siteco. <--

'IT HAS SOMETHING MAGICAL ABOUT IT,' said Christian Ude, mayorof Munich. And under-secretary Freller enthused: "It's an arena forthe 21st century and a new landmark with international status forthe city of Munich". Earlier on during the lighting tests, the stadiumwas only illuminated for the chosen few. But for the inaugurationon the 30th and 31st May 2005, the lights went on for hundreds ofthousands. The radiance and magic of the Allianz Arena hit theheadlines worldwide.A football stadium like a giant dinghy, illuminated in varyingcolours: this vision from the Basel architects Jacques Herzog andPierre de Meuron convinced first the competition jury in thebeginning of 2002, then the politicians and football functionaries,and finally the fans of the two Munich football clubs along with the

Munich residents. Before that, nobody knew for sure: Does Munichreally need a football arena, considering it already has the OlympiaStadium, an architectural masterpiece that is admired worldwide?Simply said it was the idea with the illuminated dinghy. Everyonewanted to see the project become reality - which is why itprogressed with enviable speed. The Allianz Arena is the onlygerman arena with three continuous stands? It can hold 66,000spectators and has 106 private boxes? It cost 280 million Euro? Therewas a bribe scandal that accompanied the project? The arena wascategorised as commendably barrier-free, and won the 'German FirePrevention Award 2003'? Interesting. But what really counted werethe bright eyes. With enthusiasm alone however the vision couldnot be made reality. And last but not least the know-how of two

of an extremely intelligent, innovative and maintenance-friendlylighting solution we have managed to prevail against a number ofeuropean competitors".At the time of writing of course, all 4,250 custom luminaires and thegiant balloon luminaires at the main entrance area of the stadiumhave been installed. The design of this totally unconventionalluminaire comes from Herzog and De Meuron. Its balloon housingis made of an inflammable webbed foil that with the help of aventilator within the mast is kept constantly under pressure. Fourlamps (HQI-E, 1000 Watt) sit on bracket arms within the balloon. Aspecial lighting technology confines the luminance upon themantle to less than 3000 cd/m2, whereby the use near to roads with

a high traffic level is possible.As with the Allianz Arena itself, technology and aesthetics cometogether perfectly. The results show: Munich gains - with radianceand magic. <--

companies from the Chiemgau area of Germany was required. Aswell as Siteco that was Covertex from Obing, who made thediamond-shaped air-cushions that form the casing of the stadium.2800 of these cover a facade and roof area of about 60,000 m2.Webbed into a filagrane steel structure, the cushions are made oftransparent ETFE membrane, that according to their position arecompletely white or printed with white dots. The airy quality of themembrane structure is required for the illumination with white(county matches), or with red and blue (FC Bayern München and TSV1860 München).In order to achieve the required light effects, each air-cushion hasfour luminaires. A 3.5m long housing contains six linear fluorescent

lamps (58W) as well as three control gear units. Red, blue andtransparent covers allow for colour control. Specially developedasymmetrical parabolic reflectors ensure a uniform illumination.This was not easy to realise as the lower areas of the cushions areonly partly printed in order to ensure that guests in the arena's innerrestaurants can look outwards.Of course everything was exaustively tried and tested beforeinstallation, but does that really count? At the main lighting testlast autumn it was sink or swim as the switch was activated. But thenext moment the eyes lit up.

T PRESENT, construction workers andtechnicians populate the building, but in afew months the first travellers will bepassing through the light-filled interior,gazing up at the rolling bamboo waves of theroof. One of the most ambitious and largestconstruction projects in Europe will then be

completed. Just to illustrate, here a few facts and figures: With the newterminal, Barajas Airport in Madrid will process 70 million passengersyearly and up to 10,500 passengers and 16,000 pieces of luggage perhour. Integrated into the 3Bn. Euro construction are a satellite building,rail and road connections as well as parking places for more than 9,000cars in addition to the main terminal.Aeroplanes have taken off and landed at Barajas since 1931, at that timean unassuming place a few kilometres away from the outskirts ofMadrid. In 1977 the international terminal opened its doors. Because ofrapidly increasing numbers of passengers, the decision was taken tocreate a new terminal on a free site to the north west.It seemed improbable that foreign architects could gain thecommission for such a prestigious project. But Carlos Lamela , ownerof the renowned Madrid architect's office Estudio Lamela placedutmost importance on a European partnership during the biddingphase, and gained with Richard Rogers one of the most prominentarchitectural practices of contemporary times. A good choice. In 1997the Spanish-British joint venture, (including at that time theengineering offices of Initec and Tarmac Professional Services) won thearchitectural competition. After a design phase in London lasting a fewyears, the architects team commissioned with the construction movedto Madrid in 2000 - and the building work started.In the ground plan, the main terminal appears as a sequence of parallelmodules, completed with a 1.2 kilometre long pier with bridges for upto 40 aircraft. Every module has its own clearly recognisable function.Connected to the check-in building is the customs control area, therethen follow shops and lounges, and finally the pier with gates.A single storey solution was deemed unsuitable with this size ofairport. The terminal is split into three floors, whereby the ground flooris reserved for arrivals and the second floor for departures whilst the

intermediate floor houses support functions. Spread over everythingand supported at every bay with central steel 'trees' is a huge roofconstruction whose rolling form conjures forth any number ofassociations. Lips for example, waves, sand dunes and time and again:wings. 'The roof is the architecture' enthuses Simon Smithson, projectarchitect from the Richard Rogers Partnership who manages, withJesús Hernández and Birgit Schlosser of Estudio Lamela, the projectand the team on site. 'Somehow,' he continues, 'the terminal is just ashed with a really grand roof.'Rooflights placed at the apex of the wings supply the departure areawith daylight. In order to supply the lower floors with natural light,the architects cut deep aisles between the individual modules. In thesethree storey high 'canyons' spanned with bridges, the passengersmingle, and here the traveller can fully appreciate the spacialdimensions and qualities of the terminal.A project such as the Barajas Terminal works as an idea catalyser onother involved construction disciplines, a fact that has resulted in thewhole complex being full of new impulses and technical innovations.One of the most advanced innovations comes from Siteco and can beseen on highly visible areas of the architecture. Secondary reflectorsystems have been ingeniously suspended underneath the rooflights.Two circular reflectors per rooflight reflect the focussed light fromthree 'R2 Maxi' projectors suspended on steel wires; a total of 1200reflectors and 1800 projectors (with 1000W HIT-DE lamps) wereinstalled.That this lighting solution in the departures area creates a meanilluminance of 300 Lux is in itself noteworthy, but in addition the

A Circular rooflights are seen in this early study of the terminal.


Richard Rogers Partnership and EstudioLamela have been working together on theBarajas project for the last eight years. Howdid you manage to build the almostcompleted terminal to look so similar to theoriginal drawings?

jesús hernández: From the outset wespecifically aimed to create one project teamrather than two teams from two officesworking in parallel on the same project. Inaddition we always had everyone working inone space, first in London and latterly inMadrid. We felt this was the best way ofgenerating a team spirit.

simon smithson: It helps tremendouslystarting with a very clear idea, in this case astrong diagram that arises from a notionabout how to organise the buildings' primaryfunctions. Also important is the continuity ofthe team. We have been very lucky in that theteam has been remarkably stable over the 8

21

years we have been working on the project.Finally a supportive client is critical. Manythings are required for a good building, that iswhat makes the process of architecture sofascinating.Once one of you said that Barajas Airport wasa “shed with a really grand roof“. How did youoriginally intend to illuminate the ‘shed’without distracting from the magnificentroof?

s: For me there is a fundamental question:how much ‘Architecture’ is appropriate for anairport? An airport is primarily a great bigmechanism for processing people and bags. Inview of this we chose to focus the Architectureon the roof, i.e. to put a great ‘lid’ on thecontent. The content will inevitably undergoalmost constant charge but the lid will remainconstant.How did you come up with the idea of usingsecondary systems ?

s: We had seen the system at Dresden andreally liked the quality of light there JoséAguilar, a member of the team who worked onthe detail design of the lighting, wasparticularly keen to adopt an indirect lightingsystem as a means of removing all the poststraditionally used for lighting, thereby helpingto keep the floor clear of clutter.

h: The scale of the building is outside allour experience and we have learnt a lot fromworking here on-site. We found very early on inthe construction process that in a building ofthis scale, simpler is better. The secondarylighting system is an excellent example of thesort of simplifications we have been able toachieve during the construction phase. Forexample the secondary system provides all thelight required in the piers (i.e. botharchitectural and functional lighting). Inaddition the light it produces has similardirectional characteristics to the daylight thatenters the building from the skylights.Barajas is the first project worldwide in whichFresnel reflectors were applied. What madeyou decide on this technology?

h: The two main lighting systems (thewoks and the secondary system, both bySiteco) are to a large degree custom-made forthe building, so we were very attracted tousing a new product for the reflectors. Also theFresnel reflectors being flat are much lessobtrusive than the conventional ’concave’reflectors.

s: When we saw the Fresnel prototypes inthe factory we really liked their simplicity. Inaddition I was very taken by the story (as toldby Siteco’s Design Director) as how Sitecocame to think of using this material for thelighting. It was a classic example of lateral

phenomenal aesthetic effect must be remarked upon. The HIT-DElamps emphasise and accentuate the honey gold shades of the bambooroof. Without the productive meetings between lighting advisers fromSiteco, Siemens Madrid and the architects in Madrid the buildingconstruction would look entirely different. Louis Kahn's phrase, ‘thereis no visible architecture without light‘ is confirmed by the Barajasproject in exemplary form.The ground breaking innovation can be found in the facetted reflector.For the first time worldwide, ultra flat Fresnel reflectors were appliedthat apart from their astounding Trompe l’œil design convince withunimagined optical possibilities.The passengers are also welcomed with friendly light in new formswithin the the arrivals floor areas. A total of 18000 illuminated wokseach with a diameter of 1.5 metres form a continuous roof of light. Thepleasant brightness is thanks to optimised lighting technology. A'Lunis_R' downlight (with T16 circular fluorescent lamps and highfrequency gear from Osram) installed in the centre of every 'H3' circularluminaire beams light downwards to be partially caught by asuspended reflector ring and reflected onto a large double parabolicsecondary reflector, flooding the space with warm, directed light. Thewok form was also optimised for acoustic requirements; it allows auniform irradiation of the space with loudspeakers that can beintegrated into the centres of the 'Lunis_R' downlights.Apart from these spectacular lighting solutions, the Barajas Terminalalso contains standard luminaires from Siteco: the 'A2 Maxi' floodlightfor airport apron lighting, the 'A1 Mini' floodlight for accenting thearchitectural columns as well as DUS trunking systems for the lightingof luggage zones, service areas and technical areas. A last fact serves toclarify the dimensions of the project: the trunking system totals 25kilometres. <--

h: No. In fact when the project went totender there were no services at all in the roof,but we absolutely felt the benefits of thesecondary system were overwhelming.Actually the electrical supply to the cradlesruns on top of the roof alongside themaintenance walkway rather then within theceiling void.

s: We completed the detail design of theproject in just 5 months (during the secondhalf of 1999). The final tender submissioncomprised some 4500 drawings. In such ashort period of time a number of design issueswere not really resolved to our satisfaction.Lighting was one such issue, so when westarted on-site we undertook a major reviewof the illumination throughout the building. Itwas then we made the change. Luckily theclient was very supportive and I think everyoneincluding the contractors realised howimportant the lighting was, so they were verypatient. I hope everyone is happy with theresults. We certainly are.How important was the effect of the light onthe bamboo roof in relation to the perceptionof the whole interior space?

s: The bamboo ceiling is obviously a keyaspect of the design. Originally we thought weshould wash the whole ceiling with a uniformlevel of light but as the design progressed werealised if we did this it would tend to flattenthe roof, and the roof would lose itsundulating form. Not only that, the lightingwould be a lot less efficient. The final designreally arises from the detail design of theprojectors and reflectors. There is minimal spillaround the reflectors and this falls at the highpoints of the ceiling, so helping to accentuatethe form of the roof. The rest of the light onthe bamboo is reflected back off the stonefloor which is very light in colour.

h: The bamboo ceiling is the mostimportant feature of the building. It is whateveryone notices when they enter. What ismagical is how it changes as one moves about.The lighting, not being even, really accentuatesthis sense of movement. The ceiling is like asea, forever changing.What role does daylight play in the building,especially in the canyons and on the facade?

s: Daylight is vital. For us NorthernEuropeans the quality of light in Madrid ismagical. The design aims to celebrate this,allowing plenty of daylight to enter but in avery controlled manner, always mindful of theshading requirements (the summers are veryhot) and the quite different attitude theSpanish have to sunlight. I hope the finaldesign is a successful blend of Northern andSouthern Europeans' attitudes to daylight.

h: The building is sliced into the four mainfunctional parts (forecourt, check-in,processing and pier) by ‘canyons’. These admitdaylight deep into the building, therebyreducing dependence upon artificial lighting.In the skylights above the canyons fabricdiffusers stop direct sunlight from enteringinto the building except for very smallamounts of direct sunlight that are permittedto reach the canyon floor at midday. Thediffusers also soften and spread the daylight.External louvres protect the façade from directsunlight (critical for the functioning of thedisplacement ventilation system) while at thesame time allowing views out to the platformand to the aeroplanes. Views are key-views outof the building and of the sky. In the arrivalslevel, the floor slab is hidden behind an array oflight, consisting of circular, custom luminairewoks from Siteco.How did you arrive at this solution?

h: The baggage hall is huge and we feltthere was a danger that if the floor and theceiling were continuous surfaces, the spacewould become a little oppressive and appearless high than it actually is (4.5 m). For this

reason we wanted the ceiling to be porous. Wethink the woks achieve a reasonable balancebetween creating the impression of acontinuous surface but also giving you thefeeling of the larger space.

s: Our office used a similar approach inLloyds Bank in the 80’s (also by Siteco) and theloose fit quality of the approach perfectlysuited our concept of the building as a veryflexible box.What will your next project be after theterminal opens?

s: In my opinion one cannot really makesplans in this profession. Who would havethought I would spent 4 years living in Spainworking on Europe's biggest airport?

h: It is really difficult to know how we canreadjust ours minds after such a long periodworking on Barajas airport. At present EstudioLamela is involved in the extension of WarsawInternational Airport and a New sportscomplex for Real Madrid Football Club. Maybe Iwill lend these teams a hand, who knows.

FLAT AS NEVER BEFORE.

Underneath a glass plate screen-printed onboth sides, above an anodised perforatedaluminium reflector, and inbetween nothingbut shine. The ultra-flat Lightpane pendantluminaire gives ambitious architecture a newfocus while perfectly illuminating VDU screenworkstations without glare. Which is why theluminaire designed by ON-Industriedesign andPeter Andres Lighting Consultants won theHamburg Design Prize in 2003.

LONG AND SEAMLESS. Advancedmanufacturing technology now allows Sitecoto produce large-dimension Eldaconmicroprismatic plates. That's the reason whythe Quadrature is now available with a

continuous, non-interrupted eldacon panel.The extremely low-profile luminaire becomesmore elegant and light control gains an evenhigher level of quality, and the customer nowhas a choice of two frame forms: angular orrounded.

ROUND AND REFINED. Transparencyand rigid materials join forces with the newDL800 outdoor luminaire. Hoods come in mattanodised aluminium, transparent PMMA glassor V4A stainless steel, and there are diverseoptical variations. Protection is IP66. As well asthe standard straight mast, Siteco offers theDL800 with a curved mast with either one ortwo arms. The luminaires are equipped witheconomic Siteco Savelight components.

REACH TO THE SKY. The SM300 mastluminaire with secondary reflector technologyis the new design highlight in Siteco's outdoorluminaire programme. The square orelliptically-formed secondary reflector canopyconsists of up to 408 specular facets with free-form geometry. The facets split the incominglight into brilliant points of light that aredistributed exactly and almost glare-free ontothe defined surface area. The luminaire issuitable for mounting heights of between fourand seven metres with a choice of symmetrical,asymmetrical and extremely asymmetricallight distribution. With the new Siteco LensLight System, a stray light emission of <3% hasbeen achieved.

Technology :: f u t u r e

Extremely slim and light: unlike standard reflectors, Fresnel reflectors with their convex facets are absolutely flat.

Perfect for uniform surface illumination: Siteco Mirrortec Reflector 100, designed by Ingenhoven Overdiek and Partners.

Fac e t t e d r e f l e c to r f r e s n e l r e f l e c to r

Light control with the use of microprismatic structures: that's the innovation with which Sitecorevolutionised secondary reflector technology. Fresnel technology allows the reduction of three-dimensional reflector facets to almost two-dimensional structures. Reflectors with 30 or 40mm-high facets are substituted with a 2mm-thin PMMA sheet. The exremely thin and lightweightFresnel relectors make installation work even easier and look absolutely stunning.Fresnel reflectors additionally allow a perfect light point resolution and an exactly defined lightemmission area. Completely new lighting techniques can be realised without having tocompromise the design of the lighting system. The tilting of the reflector canopy for example dueto optical reasons is not necessary anymore.The Fresnel reflector facets are attached to an aluminium honeycomb structure and enclosed inextruded sectional aluminium. The front piece is plane. The plastic surface is protected with alayer of anthracite and can be easily cleaned. This global innovation made its first appearance atthe Barajas Airport in Madrid.Please see the article on page 16.

Fresnel optics transform Mirrortec

An optical lens originally developed by thefrench physicist Augustin Jean Fresnel (1788-1827) for use in lighthouses. The constructionalmethod allows for the design of large lenseswith significantly less weight and volumecompared to conventional lenses. The volumeminimisation is achieved with a fragmentingof the lens hood in jagged annular rings(Fresnel zones). As light can only be broken onthe lens surface, the angle of refraction isdependant not upon the thickness but uponthe angle between the two surfaces of a lens,which is the reason why the lens is able toretain its optical properties.

p r oj e c t s :: Haus der Ärzteschaft

The decision for this project heralds back to the resolution of the northRheinland medical fraternity in the 1990's to unite their four corporatebodies at one site. The north Rheinland Medical Association, the MedicalProvision, the Panel Doctors' Union and the Academy for Medical FurtherEducation will in the future be residing under one roof - the Haus derÄrzteschaft.RKW Architects from Düsseldorf were assigned with the design and plan-ning. The briefing was for a building complex that could be incorporatedinto an exceedingly high-density area but that would have a distinct andstriking profile. The functional specifications for the four constructioncompanies dictated that all architectural accentuations were to be avoi-ded.This feat has been accomplished, as has been shown on the one hand bythe satifaction of the building's users and on the other hand by the impli-citness with which the Haus der Ärzteschaft blends itself into its urbansurroundings.

The ArchitectureThe structure of the architectural concept is complex and simple at thesame time:Four L-shaped construction blocks of varying heights are grou-ped together to form a system of inner courtyards. These transparent,canopied 'interior-exterior' areas consist of much more than the merefunction of opening up or accessing, they are in fact places for meeting,communication and representing. There is space enough here to breathe

deeply, there are pillars to touch and to feel, the architecture can be expe-rienced in terms of material, form and proportion.'Unity with variety', the guiding theme formulated by the architects, isapplied to the whole building complex and also to its individual parts.For example, it was important to satisfy the needs for variety with therooming as well as the needs for unity with regards to the completedesign. It is important to note that these architectural accomplishmentswere only made possible with the extensive support of the buildingauthority and his representatives.

The Lighting DesignThe early integration of lighting design in the planning process is unusu-al, even today. In this case it was different, as both the building authorityand the architect were of the opinion that this was necessary.For the ligh-ting consultant that meant optimal conditions. The lighting conceptdeveloped in the design and planning stages of the project was tende-red according to plan and realised with hardly any changes.The lighting solutions have been installed in all areas of the project, inclu-ding the park areas on the ground floors, the open areas, the meeting andoffice areas, training and conference rooms, cold and warm hall areas andthe outer areas of the building complex. The lighting installations func-tionally orient themselves according to the intentions of the architectand emphasise and accentuate these intentions. Luminaires used werepartly standard and partly custom luminaires. Siteco as overall supplierof lighting had the opportunity to prove its worth in respect to the pro-duct range, flexibility and efficiency of its luminaires.

The Office LightingIn the offices a solution consisting of two components was installed. Adaylight controlled, direct/indirect suspended luminaire supplies thebasic lighting for the cell-shaped offices. Additionally a second lightingsystem was custom-developed that apart from in the offices is put to usein the conference rooms, the casino, the reception area and the freeflowand open areas. According to the spacial function, the optics of the lumi-naires can be adapted almost at the press of a button. For some of thespaces mentioned above the system was extended to incorporate two

PAR 20 spots. Brilliant area and local lighting thus supplemented theinstallations.

Capitals of LightThe illumination of the halls was a particular challenge for the lightingdesign. Firstly, the large spacial area should have an energy-efficientgeneral lighting installation. Secondly, it was necessary for particularoccasions to be able to generate programmable lighting scenarios.The point of entry to the hall roofing construction of the multistoried,irregularly arranged concrete pillars became a capital supplementedwith lighting fixtures.The space about the columns is a rectangular areathat is closed off by the supporting structures and cut off below with alighting grid, accomodates varying sources of light. These consist of HCIpoint sources to accentuate the pillar shafts, asymmetrical floodlightsfor zonal illumination, linear luminaires for energy-efficient spacial ligh-ting and HCI directional luminaires for highlighting.With the aid of swit-ching variations these fixtures are able to create extremely differentia-ted lighting scenes.

"That good light can animate and improve work capacity is somethingthat goes without saying," says Volker von Kardorff. "Workplace qualitywas at the top of the list for the building authorities". The pure pleasureof the job can still be seen on the faces of the lighting designers fromKardorff Ingenieure.That's no surprise.To design a major 'lighting spec' isjust great fun.The platform for success is part of the BMW factory premises in Munich,called Projekthaus. Up to 2000 research engineers at the site plan BMWmodels for the future. "The building is visionary and trend-setting,"emphasises a company brochure. With this building, the seventh part of

the company-internal Researchand Innovation Centre has beencompleted. The Projekthaus is thevery centre of this complex. Fromthe outside it appears as anaustere, five-story cube. Inside ithas predominantly circularqualities. Four parts of thebuilding (quadrants) surround a

rounded atrium where in the middle the studio is situated, a cylindricalstructure that forms the central part of the Projekthaus. Automotivemodels in virtual or analogue form are created in the lower storeys, whichcan be viewed directly from the offices in the surrounding quadrants. Apresentational area crowns the cylinder.Each quadrant form is made up of an upper storey and two double storeysintersected by a gallery. The offices have a height of 3.25to 7.8 metres. Up to 300 employees can work on eachstorey.How are such giant offices illuminated? KardorffIngenieure designed a concept based on twocomponents: general spacial lighting and individual tasklighting are related to and complement each other.Extremely asymmetrical Siteco Louvre Luminaires havebeen fitted along the length of the glass facade. In thearea of the gallery balustrade, differing ceiling systemsform a three-part continuous row. Quadrature luminairesfor basic spacial lighting form a continuous line as part ofthe outer ring of direct/indirect distribution wedge-shaped custom luminaires. Light from these fittings isdistributed neutrally with the aid of prismatic enclosures.

Adjustable moptorcycle grip: the Circle tasklight from KardorffIngenieure offers functionality and symbolic added extras.

The large project areas can therefore be freely planned with regards toworkspaces. A series of suspended ceiling washers completes theprogramm. The function of the continuous row is really all aboutuniformly illuminating the large spacial area. Volker von Kardorff talks of'brackets of light'. Added to this is another effect: the lighting accents thespace in a way that avoids all thoughts of monotony.The counterpoint to the daylight-regulated spacial lighting is theindividual task lighting. Kardorff Ingenieure exclusively designed asuitable luminaire for BMW: the Circle desktop luminaire.With its leatherhandgrip and housing resembling cooling fins, the luminaire quotesspecific elements of motorycle design. "In regard to the motorcycle, avehicle that stands for the most individual form of personal transport,our luminaire represents a very individual form of light," explains vonKardorff.The metaphor makes perfect sense, and the luminaire functionsperfectly as well. Thanks to its intuitive components the Circle is veryeasily operated, and its asymmetrical light distribution illuminates theworking area from the periphary, taking up very little space.And if perchance all employees switch on their task luminaires at thesame time, that's not so much because of a herding instinct but becauseof lighting control. The keywords are 'artificial twilight'. Employees nearthe facade have no need for task lighting as they make use of the progressof daylight and react according to this. Their co-workers in the middlehowever hardly perceive the natural fluctuations of daylight. Here theceiling light is dimmed towards evening. Being able to sense the progressof time supports a feeling of health and well-being. As we said:Good light

animates!

At the same time as the Nordstern Collierystopped operations in 1993, planning for thetransformation of the giant Gelsenkirchen-Horst site was already underway. And whereonce coal dust blackened the earth, a sea offlowers blossomed four years later. TheBundesgartenschau (National Garden Show)attracted hundreds of thousands to the newlycreated Nordsternpark. At that time theadministrative board of the EssenWohnungsbaugesellschaft TreuHandStelle(THS) decided to transform the leftover collierybuildings into their new headquarters. Theproject lay in the hands of an experiencedconstruction and planning authority: the THS,established in 1920 along with its subsidiariesowns about 80,000 appartments.The construction activities apply to two shafts,the former trolley areas and coal sorting areasdesigned by the colliery constructors FritzSchupp (1896-1974) and Martin Kremmer (1895-1945). The uppermost dictum for the architectsand consultants was to preserve these

buildings as far as possible.Schupp and Kremmer had designed theirbuildings as temporary steel skeletons thatcould incorporate changes of use andenlargements.But even with this the rebuildingwas difficult, due mainly to today'sconstructional demands. Effort and care todetail however paid off. With its excellentadditions and enlargements the constructionhas been seen as an architectural jewel of urbandevelopment from 2003.The heart of the complex is the former conveyorbelt hall and coal-loading area that now formthe central entrance hall, a canteen and theadministrative areas. Single, combination andmultiple offices are in the first and secondstoreys, and the conference rooms andexecutive offices in the upper storey.A suitable lighting solution for the buildingturned out to be a difficult assignment. Thelighting technology had to be integrated intoan interior with various room heights, differentceiling structures, an intentionally visible

building technology and an omnipresent steelskeleton. A solution had to be found that couldsubordinate itself to the architecture but thatcould satisfy any aspect of lighting technology.Eventually a solution was developed by theWuppertal company Dinnebier-Licht incollaboration with Siteco. Whether restaurant,foyer or stairwell: the suspended, metal-greycorpus of the H-shaped profile fitsharmoniously into the ceiling appearance. Thehousing has completely different light sourcesaccording to the spacial situation and therequired lighting effects: CAT luminaires withspecular louvres, luminaires with glassenclosures, low voltage spots, CDMRdownlights and many others. On the undersidenext to the light fittings are light detectors,loudspeakers and low voltage supply tracks; onthe upper side are cables, transformers andignitors. The longest continuous H-profile is70m, and a total of 6000m has been installed.A special lighting solution was developed forthe meeting cubes with their glass skins

Professor Marg, you build more sports arenasthan your colleagues do semi-detachedhouses. What's your secret?It lies in the compliance between function,construction and expression. This complianceplays an important role particularly withstadiums, as it's all about the largest possiblecommunicative projects in which a society canexpress itself.As well as the recently completed arenas inBerlin and Cologne, the Wald Stadium inFrankfurt is your third project of this kind inGermany. What's so special about the roofconstruction of the Frankfurt Stadium?We plan every construction deductively fromthe circumstances that surround it. That's whyeach of the stadiums named by you has anindividual construction. In Frankfurt, theauthorities ordered a multifunctional arenawith a mobile roof above the playing field.Added to that there came a further aspect: incontrast to the omega of the Berlin OlympicStadium or the rectangle of the CologneStadium, the Wald Stadium has a rounded ovalin its ground plan. This form allows for a ringconstruction, as with a bicycle. It consists of apressure ring - the rim, a central ring - the hub,and load cables - the spokes in between.Cyclists don't understand that they actuallyride a spanned hung construction that doesnot just function vertically but horizontally aswell. We used this principle in Frankfurt - thecentral ring of the roof encloses the wholeplaying field, and constructed into its centreare the 'spokes' of the mobile roof.How have you illuminated the Wald Stadium?We lighted the playing field with a track liftedinto the central ring. The light is controllable

gmpThe Hamburg Architect Volkwin Marg About Lightfor effects, as with a theatre for example. Wealso use the reflective characteristics of thebright roof membrane in order to indirectlyilluminate the stadium.Albert Speer transformed the OlympiaStadium in 1936 with the help of hundreds ofprojectors into a lit dome. How have you usedthe light in the modernised Olympia Stadium?The stadium was abused, although its patheticcharacter is indeed suited to abuse. For us thatwas a heavy burden from which we weredetermined to distance ourselves. Especiallywith the roof we wanted to set a contrast tothe stone-like mass of the historical building.The roof appears from the outside like a giantfloating corona, and inside the lightingemphasises the filigree structure of theconstruction extremely well. So light herestands for lightness, weightlessness andornament.What meaning does light have for you as anarchitect?During the daytime, Le Corbusier's sayingabout the play of bodies within light still hassignificance. That means that all architecturelives from its plasticity in natural light, which iswhy our whole array of traditional architectureis very profiled and reliefed. Seen exactly, weknow about two variations of natural light:warm daylight and cool moonlight. And justwhich magical effects moonlight can createcan be seen in Venice. Sansovino's St Mark'sLibrary for example looks like an opera stage inmoonlight, because the moonlight shadowsand the areas of dirt upon the facade do notcoincide. That gives the impression that theshadows are on the wrong places, as with aroughly painted theatre backdrop.


39

And now there's artificial light as well.Architecture had to wait a long time for theuse of artificial light. In the theatre it wasdifferent. Think about stage directions forlighting. Candlelight was used for accentlighting. The adaption for architecture thoughtook a long time. Now of course we have thetotal paradigm shift because we illuminate,colour accent and project with atificial lightand so on. But of course light should alwaysserve a function and not be an end in itself.What do you think about urban lighting?The glut of technically produced light todayoften leads to a devaluing of light, to lightpollution. It's similar to eating. Too manyfoodstuffs cause illnesses and isn't exactly thebest thing for a qualitative cuisine. Good foodis a question of quality, nicht quantity. Thesame goes for light as well - moderation iswhat's needed.Is that the same for the Times Square,Piccadilly Circus or the Reeperbahn? Take Hamburg for example - there's theReeperbahn on the one side and the inner cityaround the inner and outer Alster. For thelatter there have been very stringentregulations as to aspects of town planning.These allow for the noblest shopping street inHamburg, the Jungfernstieg, to haveilluminated advertising on the ground flooronly, and just in white! And on theReeperbahn? You're allowed to really doanything here, the louder the better. So there'sthe cool noblesse of the inner city and thevulgar lighting effects of the Reeperbahn. Thatis exactly how it should be: cultivatedmoderation on the hand, and completefreedom for everybody on the other.What do you think of building vicinitylighting? Everything today is wrapped in gaudy sweetpaper colours. Basically speaking, thenighttime view of the Acropolis is ruined.That's the same for Carcassone. And inGermany it's the same story, all of the inner-city areas are now being subjected to the

same treatment. It is really perverse - as if Iwere to put custard on top of every meal.Although I do think that it should not only bebanks or amusement halls that are allowed tosignalise the nighttime profile of a town.History has to be seen in the correct light.Hamburg and München are exemplary in thatthey have been able to keep their wonderfulinner-city silhouettes, whereas other citieshave destroyed theirs. Hamburg and Munichserve to show that quality needs a completecreative staging.In China you are designing a complete town aswell as various large buildings. Are theredifferent requirements for light in China, oranother attitude to light? The benefits of technology are falling overchinese towns and cities like avalanches. Thatis the case with traffic, but also with lighting. Acultivating of light in respect to moderation iscompletely unknown there. Modern lightingtechnology with its dazzle of moving lightpoints is changing the centres into copies ofLas Vegas.How do you cope with that as an architect?In the next twenty years half a billion peoplewill move from rural areas to the city. Half abillion, that means that in China one hundredcities with five million habitants each willneed to be built.You’re building one at the moment: Luchao.What we are planning is more like asettlement - originally Luchao was acommuting unit of 300,000 people forShanghai, but in reality a million people livethere. Although compared to an exploding 15million metropolis that's really quite small. Butfascinating.Light and luminaires are elements ofarchitecture. How interesting do you find theproducts of the lighting industry? We have developed luminaires ourselves:office luminaires, decorative wall luminairesand architectural light. We do though moreoften work together with lighting designers.And sometimes we work with the lighting

industry in order to develop customluminaires. It is usually the best way to selectproducts though that are already on themarket.Recently your office won the first prize for thedesign of the Alexanderplatz in Berlin. For thesquare lighting you suggest very highluminaires, for example floodlightinstallations. Are you thinking aboutsecondary reflector systems? Yes, we are definately thinking about that.Although just at that point we find a dialoguewith the lighting designer or the lightingindustry very useful. Questions about theluminaire positioning or light quality wouldthen be resolved in the dialogue.Is there a lighting effect that you would like tosee somewhere, but where there is not yet atthe present time a luminaire to realise that?In Luchao for example, the commuting city inChina, there is an exactly circular lake with adiameter of three kilometres. We want toinstall a cloud tower in the middle - that's anavigable construction as high as the EiffelTower, that gives out water mist from the topthat should be illuminated during the evening.How can I do that? The illuminated cloud. Youcan't buy that in a catalogue, you have todevelop it. <--

If secondary mast luminaires such as the SM 500 (picture, left) adorncountless boulevards in Europe, it is not only due to their striking goodlooks. The amazing career of secondary reflector technology (known asMirrortec at Siteco) is primarily due to photometric advantages.Maximal glare limitation is the first thing to mention. This comes fromthe fact that the facetted reflector splits extremely narrow distributionprojector light into numerous brilliant light points. Mirrortec offersfurther advantages though. Pedestrians can enjoy an unobstructedview of shop windows and facades because the light source is notvisible. Due to the possibility of precisely aligning light, finely gradedlighting effects can be achieved. The high light output ratio of 52%proves that Mirrortec is an extremely economic method to place streetsand squares in the right light.And just how masterfully architects and lighting designers can workwith the technology can be seen with four recently completed projects.At Georges Quay in Dublin the specification was to create an urbanzone with excellent lighting qualities. The luminaires should adaptthemselves harmoniously to a surrounding of large commercialbuildings. A Mirrortec solution with highly efficient lightingtechnology was favoured, not leastly because of the accompanyingreduction in luminaire spacing. A custom solution was developed - theSistar reflectors, combined with R1 Mini projectors. The result waspleasing for architects, city officials and inhabitants alike.Quality of design and lighting were also required for the Herschelplatzin Mannheim. Town planner Edgar Vierneisel transformed anuninteresting inner-city area under difficult conditions into adistinctive urban landscape. In association with tree plantation andstreet furniture, 36 SW Disc luminaires on cylindrical stainless steelmasts form an urban 'light square'. Vierneisel tackled the specification

to integrate a bordered schoolyard well. The three-dimensional fencingof glass bead blasted stainless steel rods and the elegant SW Disc instainless steel design were harmoniously matched to each other.Passers-by experience the luminaire as a unifying design element. Atnighttime, various luminances and a planned play of light and shadowcreate an added interest.

In Sale in England, a secondary mast luminaire with classical designgraces the newly designed town hall square. The 'Galaxsie' ischaracterised by three metal rods that support the reflector disc - a formthat has a timeless appeal, as its design contains the essence oftraditional street lanterns.

And lastly the Sachsentor project from Ulrike Brandi, the lightingdesigner from Hamburg. The Sachsentor, lying in the heart ofHamburg's Bergedorf district, is both shopping area and old city centre.Historical buildings rub shoulder to shoulder with post-wararchitectural scars. "For years", explains Ulrike Brandl "the spacialquality was characterised by a confused clutter of buildings". Planningfor a redesign of the district began in may 2002. The architects Loosen,Rüschoff + Winkler from Hamburg aimed for simplicity and elegance:"Instead of brashness we wanted to create stimulating places where afeeling of comfort and peace could be gained". The architecture thatensued certainly satisfies these requirements. With an unpretentiousground design and unified street furniture, the architects helped thedistrict to gain a very acceptable appearance. The highlight of theSachsentor is the SM500 secondary luminaire, partly designed byUlrike Brandi. "The presence of the luminaire in this relatively tightarea", expains the lighting designer with theatrical understatement,"requires a new, banal form". <--

Theinstallation of modern lighting systemsformed the conclusion of the redevelopmentscheme. Luminaires with secondary lightingcontrol (Galaxsie) as well as various mastluminaires with radial facetted reflectorsystems (SQ 100/200 and DL 500 Midi/Maxi)were deployed.The Galaxsie has now almost become a trademark of the metropolis on the Bosphorus andilluminates pedestrian zones and parks bothin the recently modernised Besiktas area aswell as the Taksim part of the city.Promenades, piers and squares along theBosphorus as well as the Bagdad Boulevardwill be following shortly. A success for Siteco,a gain for Istanbul.

'Eminönü serves as the crossroads of Istanbul',states a much-referenced travel guide. Andindeed many bus, train, tram and ferry linescome together in the old town area that lies atthe southern end of the Galata bridgespanning the waters of the Golden Horn. Butit's not only public transport passengers thatpour daily to the hundreds of thousandsthrough Eminönü. Tourists also flock here,pilgrimaging to the new mosque, waiting fora ferry or browsing through the egyptian spicemarket. And the area swarms with merchants- since byzantium times. In view of such ahectic life style, it is not surprising to hearEminönü described by a person in the knowas 'the most important tourist destination inTurkey'.This immemorial, pulsating part of the citynow shows itself in a new light. As part of alarge-scale urban redevelopment scheme (see

From the Hagia Sophia to the Blue Mosque, fromthe Artemision to the Bosphorus Bridge:Miniaturk is made up of the most famous turkisharchitectural works ever. 105 models with a scaleof 1:25 can be viewed in the park that opened itsdoors to the public in April 2003. Centrallylocated on the banks of the Golden Horn,Miniaturk is already ranked as one of Turkey'smost popular tourist attractions. The lightingconcept was developed by the architect CengizOzdemir together with Siteco. 30 Galaxsieluminaires with secondary lighting controlilluminate the exhibition area with a pleasantand glare-free light, and show the exhibits inhours of darkness to their full advantage. Thecafé terrace and entrance area have speciallighting solutions. Sw-Disc secondary luminairesilluminate flags in the entrance, and in the bararea a secondary reflector system of SiStarreflectors and R2 Mini projectors was installed.

In conditions of flooding the continent is just switched off, when a storm blows it's tornapart. It breaks down into tiny pieces or tongues of light. But even inthe quietest of moonlit nights the contours still tremble; the continentnever completely comes to rest. How could it be otherwise! Europenever stops flowing - although in this case that's not justmetaphorically meant but also literally. Europe as a play of light ormirage in the Kupfergraben in Berlin: the projection with the title 'FataMorgana' has grabbed the attention of countless tourists and nativecity-dwellers since May 2004.The joint project of the artist Manu Kumar and the british architectTom Heneghan came about within the scope of the internationalcompetition 'Constructed Connections', promoted by theHauptstadtkulturfonds and the Kulturstiftung des Bundes. Kumarchose as a location the Iron Bridge built in 1797 that combines the areabehind the Zeughaus with the museum island. Hidden under thearches here are 160 printed acrylic segments and the appropriatelighting technology. 600 Siteco Monsun luminaires project theglittering image of Europe onto the water surface.The Old World, dancing on waves, permanently falling apart andcoming together: that alone would be a sight for the gods. But Kumarhasn't restricted himself to a european view of things. He presents thecontinent as a global village, an urban landscape that reaches fromLisbon to Kiev. To achieve this he's made use of satellite pictures fromLos Angeles and Peking that he's minutely processed and re-handled.Within the light of art is now mixed east with west, old with new andpoor with rich. All things considered, it's about the melting together ofspecial cultures towards a dreamed of, a presaged and halfimplemented global culture. In the words of the art historian TomFecht: ''the work shows me beyond my conscious awareness animpression, or better a psychic perception of the world as somethingnew, as something with a passionate intactness''.

are not to be envied. During the daythey sleep badly, during the night they fight against weariness. Arehigher lighting levels a help? Is light capable of influencing our innerclock? Questions like these were investigated in a field study overseveral weeks by Dr. Angelika Guth. 130 shift workers from theVolkswagen factory in Wolfsburg participated in the test organisedby her and biologists from the Ludwig Maximilian University inMünchen. One half of the experimentees worked in a normally litenvironment of 400 lux, the other half in much brighter light: specialSiteco luminaires created a glare-free lighting level of about 2000lux. The very first test results caused the ergonomists and doctorsto look more closely. Light influences! Clinical measurements andexperimentee surveys clearly proved this.Just why the inner clock reacts with light is explained by thechronobiologist Till Roenneberg: "Light falling onto the retina doesnot only start the viewing procedure within the brain", explains theexpert from Munich University. "It also inhibits for example the

distribution of Melatonin, the hormone responsible for tiredness".But in order for light to function as a regulator of time, a high levelof lighting is necessary: "The source size is natural sunlight", saysRoenneberg. Science, explains the Professor, has to busy itself withthe question as to whether the continual under-supply of light leadsto conditions such as sleeplessness, moodiness or depression.The chronobiologist's results are a challenge for lighting designers.Workspace lighting, especially within industry, will not only have toorient itself to viewing tasks but also to its biological influences.Vitality and productivity henceforth become major themes for thelighting industry. Siteco has accepted the challenge. The industryluminaire Light for Vitality, emitting 2000 lux with absolutely noglare, has been put to use for some time now. At Osram in Eichstätt- and at Volkswagen in Wolfsburg.

Since its publication, the 440-page Book of Light has found strong interestin the lighting industry. Whoever does not yet own the new - and novel -catalogue should reserve his copy as soon as possible.The Book of Light is aimed at architects and lighting designers, and shouldhelp them with the aid of a problem-based approach just how to betterdesign interior and exterior spaces with light. A problem-based approach:that means that not the most suitable luminaire is the starting point, butthe most suitable light.The conceptual chapters of the book are dedicated to lightingspecifications.With the help of examples from the areas of office, industry, traffic,shopping,public and sports,all relevant aspects are addressed and suitablesolutions suggested. In the pages following, product chapters showsuitable lighting instruments to implement lighting and spacial ideas.Thelayout takes special notice of formal aspects of the luminmaires. Requiredinformation for detailed lighting design are contained on the Planning CD,enclosed within the Book of Light.The publication is available in german, english, spanish, italian and french.Order your free copy now.

Despite glowing quasars, about 300 million years after the Big Bang it was the time of the 'Cosmic Dark Age', ascompact hydrogen atoms absorbed light.The universe first became penetrable for light with the shining of the firststars and the splitting of these atoms. Recently, astronomers discovered that the cosmic illumination had in themean time been extinguished. With the explosion of the first part of the star generation the hydrogen ionisationwas interrupted. The work was first completed with the next generation: about a billion years after the Big Bang,the ultimate light was switched on.

Let There Be Light! And the Darkness Came.
