Let’s SLIDE No, English is not our mother tongue. Nonetheless, the French and German editions of our new Hawa magazine are also called SLIDE. After all, our hardware systems slide all over the world. But in particular because SLIDE sounds so dynamic, short and sharp and glides over the tongue like a HAWA-Junior over its tracks. To slide means to glide or to push. It suits us. Life is movement. Movement needs space. Open space. People need to be able to open up their living space with effortless movements. And we contribute towards this invigorating, refreshing, enlightening openness between people and rooms, towards dissolving the categories of «indoors» and «outdoors» with our systems. We want you as our customer to find our chosen subject of light entertaining and informative and to share our enthusiasm for our philosophy. We know that the best products and developments are always produced by people with a philosophy, with enthusiasm and vision. That is what we want. And you? Let’s slide!

Light
Light gives us space The restaurant is called «Blinde Kuh» (Blind Man’s Bluff) and guests find the way in much easier than the way out: everything is pitch black inside. Even lunch is a midnight feast in this restaurant. The darkness does not bother the waiters and waitresses. They are blind. And when guests leave the restaurant and discover a red wine stain on a shirt they feel relieved to be able to see it.
Light is life Light sets the cycle of day and night, light lets feelings ripen in spring and peaches in the autumn. Light enables us to see and be seen, to find and observe, light enables eye contact and thus forms human relationships, light lets plants and reproduction blossom by means of photosynthesis, candlelight or bioluminescence, the trick glowworms use to flirt, all depending on the species. Humans have researched light. They have understood that anything visible also transmits light, whether as a light source, such as the sun or a fire, or as a reflection, such as the moon or snow. They saw light mirrored on lakes. They looked through a water glass and saw light refract. They passed light through a prism and saw spectral colours emerge.
Light is play Many people got to know about the power of bundled light as children by burning a hole in the neighbour’s fence with a magnifying glass. Inventors developed lenses for microscopes and telescopes, learned how to capture light on light-sensitive media, learned how to make it visible in the darkroom, to project it and make it move again using a «cinematograph» in the «cinema», where we can now watch real life at work.
Light and space Isaac Newton described interference so we now know why a CD that is actually silver shines in every possible colour. We humans found out that light is one of the many electromagnetic wavelengths which we went on to discover one by one. Since then we have listened to radio with long waves, watched television with short waves, caught echoes with very short radar waves, heated up leftovers with microwaves, measured heat with infrared, looked inside closed luggage with x-rays and made targeted use of laser beams in many areas of industry. And we protect ourselves with suncream against ultraviolet waves. The shortest and thus most energetic wave is
osmic radiation, used by astronomers as an c instrument to measure time and space. We have measured the behaviour, distribution and speed of every wave type, we have built devices and sent them into space where they discover new galaxies in space and time and expansion and trace the development of the universe back to its origins. We have travelled from the light of the world to the light of outer space. Light and space belong together. Because – and that is what is so special about this one particular wave somewhere between infrared and ultraviolet: it is visible and makes things visible; world and space.
Light creates atmosphere We have long since discovered enough about the nature of waves and energies to make light ourselves, for the bedside table and other beautiful or useful purposes. Light designers and interior designers are grateful to researchers. And we are grateful to light artists and interior designers. They make it clear to us that light is more than just a means of ousting darkness from our world. It is light that makes contours, colours and structures something we can experience. And the things
Polar lights

The heavenly display of colours one can see in the high north and deep south are caused by high-energy solar particles that illuminate the oxygen in the earth’s atmosphere through a light-producing chemical reaction.
The ghost lights also known as «willo’-the-wisp», really do exist. They can be seen over marshes and swamps. Decomposing plants release methane, decaying animal cadavers release phosphine. Both gases rise to the surface of the swamp. Phosphine self-ignites on contact with oxygen and then ignites the methane gas. The flames only flicker very briefly, «hopping» over the marsh wherever gas is rising to the surface.

we experience have different impacts on our mood. Light makes us feel buoyant. We use the word «light» to describe what we see and how we feel; it is the opposite of both dark and heavy, words used to describe moods of a less pleasant nature.
Light ideas Artificial light can supplement sunlight but it cannot replace it. Cleverly directing sunlight into buildings has always been considered an art. Not only centuries-old synagogues, chur ches, temples, shrines and mosques bear witness to this art, but also modern constructions of a sacral character such as banks and museums.
As opposed to large buildings, skylights were of practically no importance at all for ordinary houses. Only light coming in through side windows brightened the rooms, and the windows were often closed with shutters to keep the heat inside or outside the house. Indoors and outdoors were like night and day. New materials have brought indoor and outdoor areas closer together, in some cases creating a virtually seamless transition. «Light-flooded» is the term used in real estate advertisements with reference to skylights, spire lights, floor-to-ceiling windows, conservatories and generous panorama fronts made of glass. The office blocks and other large
buildings of today are often clad completely in energy-efficient high-tech glass. Today we can slide façade elements and entire fronts. It is only when a house is in line with the different light and heat conditions during the day and during the different seasons that room and light can play together in harmony. The first thing a human sees is the light of the world. Preferably every morning. It accompanies him all his life. And increasingly inside his house. There, it lifts his spirit and he sees everything with a little more clarity. Even the red wine stains.
The solar candle The bright column sometimes seen above the setting sun and reminiscent of a candle is nothing more than the reflection of sunlight on ice crystals in the Earth’s upper atmosphere.

The life of our Sun A gentle ray of morning Sun falls through the bedroom window at 300,000 kilometres per hour.

They make us happy, these rays of sunlight consisting of infrared, ltraviolet, x-rays, gamma rays, radio waves and microwaves. A ray of Sun travels for eight minutes to reach the Earth. The day begins – Life on Earth. What humans call the Sun is, in the opinion of scientists, a kind of hydrogen-based nuclear power plant with a core temperature of 16 million degrees centigrade, a type of plasma light bulb that destroys 5 tons of material per second and therewith releases a billion megawatts of energy 384 billion times around the clock. It is the Sun that makes life on Earth possible. The Earth spins on its axis and the Sun turns that movement into night and day; the Earth revolves around the Sun and the movement gives us the seasons. It shines on the poles from a flat angle and lets the water turn to ice; it shines frontally on the equator and heats the deserts. Astronomers reckon the Sun will turn into a so-called «red giant» in around two billion years, raising the average temperature here on Earth to approximately 100 degrees centigrade. In around eight billion years
the Earth’s crust will melt to lava. One day the Sun will burn out as a «white dwarf», and one night, as a «black dwarf», it will cool out and simply go out, unspectacularly, as just another of the 200 billion stars in the Milky Way, which itself is just one unspectacular galaxy among an estimated 50 billion galaxies we can observe from the Earth with today’s modern technology. But for the time being our Sun will continue to shine. Until the day draws to a close and we go to bed. But it will not get dark: we make light.
Let there be light. The illustration shows a coloured total view of the sky, combined from measurements taken by the satellites «Iras» (infrared radiation) and «Cobe» (cosmic background radiation). There are no stars to be seen – they are imperceptible to infrared measurements. The glowing belt at the centre is the heat radiation emitting from interstellar dust in the Milky Way. Astronomers have detected a number of regions in the belt where stars are born.

Light artist
Gerry Hofstetter has illuminated Egypt’s pyramids, icebergs in the Antarctic and the Arctic, the castle in Transylvania, governmental buildings, landscapes, nuclear power plants and even the Matterhorn; and Swiss newspaper Neue Zürcher Zeitung once named him an «architect of castles in the air made of light».
Gerry Hofstetter Hofstetter (47) is married and father of two children. He lives and works in Zumikon near Zurich. The ex-investment banker has managed his own agency for marketing, events and design for fourteen years, and has transformed monuments into light-art objects for the last eight. The idea came to him as he stood in a barrage of light on a discotheque dance-floor. Hofstetter projects photographs or self-painted or self-designed images onto glass plates – painting has always been his passion since childhood days. Motive and projection surface must be a perfect match; contours, angles, dimensions and ambient light need to be just right, as does the location for the pro8 slide No. 1
jector. The penultimate task is to get all manner of possible and impossible approvals and make sometimes extensive travel arrangements, with the final implementation depending on the weather, a functioning infrastructure and the non-occurrence of the unexpected. Hofstetter flies helicopter himself, but he also projects his art from ships or off-road vehicles and even from trains. These performances are expensive and are supported by sponsors, patrons and partners. The light artist receives orders to produce artwork from governmental and non-governmental organisations, authorities, foundations, museums and corporations. www.hofstetter-marketing.com
What is light?
What was the problem?
What’s next?
Gerry Hofstetter: Light is hope. Without light there would be no life on our planet.
The complexity of the performance and the weather. The illumination had to cover a height of 1,000 metres and a width of 400 metres. The helicopters were heavily laden with projectors and the entire infrastructure, including energy sources. There were no experience values to fall back on, and we had to be very «inventive». The first attempt in December was battered by winds of over 100 km/h. The second attempt in March took place in warmer air.
Illuminating the glacier on Mount Kilimanjaro at nearly 6,000 metres above sea level in Africa is an important project taking place in January 2009.
How do you use shadow? I can use shadow to create tension, for instance when organising an event. Of course, it has to be dark for projections, as too much residual light would disturb the lighting.
What was your most difficult project? Illuminating the Matterhorn from three heavyduty helicopters. The first attempt in December 2005 and the second at the beginning of March 2006 failed due to bad weather; the third attempt at the end of March was finally successful.
What effect did that have? It had a detrimental effect on the helicopter’s performance and forced us to rethink our calculations. We also had a lot of filming problems, and it was very difficult to photographically document the entire projection from the air.
What is the subject? Refugees. It is a project for the UNO refugee commission. The glacier on Mount Kilimanjaro is melting very quickly due to global warming, and the UNO wants to draw attention to the fact that climate change causes more refugees than war. We want viewers to take a good, hard look at the monument and think about the sustainable development of our planet. The same applies to my other Light Art Expeditions.

Fire and Neon I am a poly-mechanic in my second apprenticeship year at Hawa. A poly-mechanic makes components, often single components consisting of various materials. Small repairs, for instance to machines, are also part of the job. I have a number of favourite lights. I like neon. I also like luminescent colours. Mind you, the light in my bedroom is from normal lightbulbs. My other favourite light is fire, for instance when having a barbecue with friends. My hobby also has a lot to do with fire or firing: I am a competitive marksman – I came to it through my father, who is president of the Affoltern shooting club. Shooting is a tradition in our family.

Sliding day, light and night One hundred years ago people spent ninety per cent of their time outside. Today, they spend ninety per cent of their time indoors.
This is because light lowers the production of melatonin, the hormone responsible for tiredness and bad moods. The season of shorter days therefore brings with it greater tiredness and lack-lustre moods – all the more so if melatonin levels are not balanced out by frequent exposure to the light out of doors like in the old days.
However, not everyone who feels tired and droopy during the winter season is necessarily a «patient» in need of a doctor, a diagnosis, therapy and medical insurance. A certain «renaturalisation» of the rhythm of life will brighten the spirit in the true sense of the word. The «indoor-outdoor aspect» is again of central importance, i.e.: the walls and their alignment towards natural light. But there is more to it than simply creating as much translucency as possible – i.e.: creating more and larger openings – we are looking at possibilities of adapting this translucency to nature outside and our mood inside.
However, it is not only the lifestyle but also the season that is responsible for the lack of light. «Seasonal Affective Disorder» SAD, or «winter depression» in the vernacular, has become the established diagnosis. Studies show that
Chronobiologist Anna Wirz-Justice from Basel has thoroughly researched the relationship between light, sleeping rhythms and depression. She postulates a relatively simple form of «light therapy»: people diagnosed with season-dependent depression should sit in front of a therapy lamp with an output between 2,500 and 10,000 lux for 30 to 60 minutes each day. According to Anna Wirz-Justice, four out of five patients will start to feel significantly more buoyant after just three to four days.
The field of international architecture has come to realise that window shutters are not just decorative ornaments but a decisive factor for a better quality of life. Even smaller projects can give back the importance bestowed upon light by Le Corbusier, who once said of himself that he composed with light. The components are available on the market: light regulating systems in many forms of sliding window shutters and façade elements that, thanks to their flexibility, enable a stylish and healthy interaction with light.
Owls and larks
Summertime and winter time
Healthy light balance
Chronobiology differentiates between two chrono-types: the «larks» as early risers who are productive during the morning hours, and the «owls» who are grumpy in the morning but come alive at night. Developments are possible: teenagers and adolescents are usually nocturnal «owls». The proportion of «owls» is larger among city dwellers, too – their lives are less influenced by the rhythm of the sun and nature than the lives of people who live in the country. The lives of city people are more oriented towards the «social rhythm of life» in the city.
Till Roenneberg of the Centre for Chronobiology at Ludwig Maximilian University in Munich evaluated 55,000 chronotype questionnaires completed online and supplemented the results with his own research. His conclusion: the «inner clock» doesn’t care about the time on the wristwatch, the body ticks along to the rhythm of sunlight. The putting the clock back one hour in the summer therefore has no influence on the body’s sleeping-waking requirements – it will at best affect the sleepingwaking behaviour of its «owner».
Anyone enjoying more light during the morning and less towards the evening will fall asleep faster. Softer light is more recommendable during evening hours. Long, light summer evenings make it difficult for many people to fall asleep. Going out into daylight for at least one hour a day will help achieve a deeper sleep. This also applies in cloudy weather: the light outside will still have a strength of 1,000 to 5,000 lux, whilst office light only reaches between 300 to 500 lux.
Our sleeping-waking rhythm is also becoming increasingly detached from daylight. Chronobiology says reverting back to how it should be is both possible and healthy. And architects and craftsmen can be of help. The time of day and the rhythm of life have amicably gone their separate ways. Before Edison invented the light-bulb, people went to bed at ten o’clock in the evening because they were tired and because it was nighttime. Today they book online holidays at midnight, zap through television programs or play online games with Canadian contemporaries. In artificial light. They also spend most of their time during the day under artificial light. However, sunlight is still the impulse generator for the body’s internal clock, and the body can get out of sync if it is missing. Many people react to a lack of sunlight with performance and mood swings, quite a few even with depression.
10 out of every one hundred people feel more tired, less able to concentrate, less enthusiastic and sadder between autumn and spring than they do in summer with its long, light days. The main reason lies in the lack of light.

Light is breakthrough Anyone who has gazed in the eye of darkness sees light in a different light, says former Swiss radio presenter and present day crisis coach and author Ruedi Josuran.
The Gotthard road tunnel. 17 kilometres. Twoway traffic, jostling trucks, the light is diffuse, all in all a trip through hell for claustrophobia sufferers. I am on the way to Ascona to visit a retired lawyer from Düsseldorf. He has suffered from winter depression for a considerable length of time. He uses a phrase I often encounter: «I cannot yet see light at the end of the tunnel». If light is lacking then so are warmth and energy. This is the main cause of winter depression and one of many causes for exhaustion depression, known not purely by chance as «burnout»: anything that burns out goes out. It gets dark. I know from experience that a strongly cemented construction, not unlike a tunnel, full of defence mechanisms, accusations and explanations exists to justify all sorts of situations in life, including and perhaps especially for burnout. One goes out of one’s way to avoid tunnel experiences and dark areas. And anyone who dares enter the tunnel is soon gripped with fear and wants to go back out again to the way things were «before». But the breakthrough always lies ahead.
Anyone who dares enter the tunnel and embrace the darkness will slowly understand its meaning and will see the end of the tunnel. Things brighten up and life appears in a new light.
Ruedi Josuran works as a self-employed crisis coach. His latest book, «Seele am Ab grund», was published in April 2008 by Verlag Textwerkstatt in Olten.
The south exit from the Gotthard tunnel is a little deliverance every time. As a person from Switzerland’s south I hunger for sun, warmth and light. It is only in contrast to darkness that light becomes a treasured source. By the way, a medical specialist and I recommended light therapy to my friend in Ascona.
One goes out of one’s way to avoid tunnel experiences and dark areas but it is only in contrast to darkness that light becomes a treasured source.
Light therapy – home-made Even the design of the home can be a form of light therapy: an intelligent floor plan oriented to the times of day, a sunny exposition, living rooms facing the sun, bedrooms facing to the east, large windows, conservatories, no deep balconies that absorb light. Let in the warm sunlight, cool daylight or diffuse zenith light from above. But there is more to it than just letting in light: the idea is also to accentuate sources of light and use them to create atmospheres. Those whose living environment 12 slide No. 1
is not so privileged should choose a bright interior and avoid blocking out the light with big plants in front of the window, high trees and bushes in the garden, not to speak of dense curtains or blinds. The construction or fitting of windows, conservatories, skylights and spire windows has become popular. But these elements should not only look good but also be fit for everyday use: window shutters one cannot close without practically falling out of the
window will not see much everyday use. Modern, highly robust and in particular practical sliding systems for façade elements and window shutters are excellent for flexibly flooding a room with light – or blocking it out. With a few simple hand movements and very little force. Even exposed fronts can achieve a flexible balance of light and warmth in this manner.
Disco light I have been with Hawa since 1994. At first I worked full-time, but now work 80%. I package parts and assemble small component groups, either by hand or with a machine. I like working at Hawa. We are a fantastic team. Sometimes I sing and whistle. My favourite light is a clavilux. I play keyboard, pop music and hits. Sometimes I like to give playback performances. I connect my clavilux to my keyboard and the light flashes in time to the music, sometimes fast, sometimes slow. If i need to learn, or freshen up, the words of songs for one of my shows I’ll buy a CD and listen to it while I work. Afterwards I’ll go to a second-hand shop, buy some fitting clothes and I’m ready for the show.

The candle I work in quality inspection at Hawa. For instance, I take random samples during the incoming goods inspection, or follow up error reports. First sample inspection reports are also part of my job. My first profession was as a plastics technician, or fitter as it was called then. But then my career developed more towards quality assurance. My favourite light is candlelight. I love candles at any time of day or night. Candlelight is warm. It is much more than a light that simply brightens a space; it is living light. I have a large garden and I light candles there, too. It takes around a quarter of an hour to light every candle in and around the house. My deceased wife was also very fond of candles. And that is another reason why candles mean so much to me: my thoughts are with her every time I see the glow of a candle.

Wood lives forever But a damning light is cast on unprotected wood.
Nature lives. Nature dies. It’s a natural cycle. Wood is a natural product which nature builds up and breaks down again. It swells up when wet and shrinks again when it dries out. It provides nutrients for mould and algae. It changes colour and becomes rotten with age, losing its strength. Wooden houses have nonetheless lasted for many centuries. We have learned to protect ourselves against the elements by building houses. And we have learned how to protect our houses, and are still learning today.
The protection needed is determined by the impact of the elements and the necessity for dimensional accuracy.
Sun-screen for skin and wood
suncream as protection against UV rays. A colourless and pigment-free varnish will let radiation through, a glaze will block around fifty per cent, and an opaque coat will reflect nearly all of the sun’s rays. Nearly – it absorbs some of the rays itself and cannot protect the wood forever. However, the process takes much longer and starts all over again with every new coat.
Light has a heavy impact on wood. The sun’s UV rays are especially intensive at high altitudes and cause the wood to age rapidly. First it turns grey, then dark brown and much later almost black. The natural development of colour underlines the character of real wood. Dark types of wood can become lighter, and colour changes in exotic wood can be striking and quick. The natural process must be stopped wherever these developments are undesirable. Wood needs a protective coating with sufficient pigments to prevent sunlight penetrating too deep, just as humans need
«There is no limit to the durability of wood», says Prof. Dr. Ing. Peter Niemz of the Institute for Building Materials at Zurich’s Federal Institute of Technology. Condition: no moisture, no infestation and a constant climate with no UV radiation. Wood absorbs light easily, especially lignin – a macro-molecule that causes the lignification of plant cells. Short-wave UV radiation starts to decompose the lignin on the surface of the wood and causes it to turn grey. The wood becomes cracked and rough when water washes out the decomposed particles.
Leave façades to nature? Even natural wood façades will remain stable for decades if properly designed and implemented. That is the opinion of Dr. Klaus Richter, Head of the Wood Department at Empa, Switzerland’s test and research institute for materials. However, suitable coatings are necessary to maintain the appearance and colour of wooden components. Weather, climate, orientation and roofing all influence the strain on wood and call for various treatments. Windows, shutters and external doors need strong protection against warping. However, nature can be left to take its course with slim façade cladding, which is allowed to expand slightly and undergo significant changes in colour. The level of protection needed in each case is determined by the impact of the elements and the necessity for dimensional accuracy.
Grey instead of old
Wood with a future
Anyone wanting a wood façade with a natural silver-grey patina will have to be patient for around eight years and accept a mix of grey and brown tones in the meantime. Unless they use wood pre-greyed through artificial UV radiation. Another option is to apply a silver-grey pigmented paint that degrades over time to reveal the wood surface which has meanwhile turned grey. Artificially radiated façades still need a protective coat to protect them against moisture.
Researchers are working hard to make wood even more attractive as a building material. The cruxes are knot zones, pitch pockets and the depth profile. Chemical engineers are developing new primers and topcoats to prevent lignin from degrading, and nano-technologists are working on new processes. It seems that in the future we will use ultra-fine iron oxide or titanium dioxide particles measuring less than 20 nanometres (billionth of a metre) to turn wood coatings into durable protective agents. The learning process continues.

Light sells I: Urech Optik Aarau By Thomas Schoch, light designer and interior designer at lichtblick
A well-established Swiss eyewear boutique was to receive a new look after ten years. The structure of the existing room, which measures 20 metres in length and only four metres in width, was intentionally left unchanged. Designing the lighting was a real challenge. The length of the room is underscored by an end-to-end furniture piece at the centre. The exhibition units are movable and can be pushed to one side to make room for events. Sunglasses are presented in illuminated recesses, whilst glasses and lens accessories are stored in the cabinet below. The surfaces of the longitudinal walls reflect the subject of the boutique: the walk-through 16 slide No. 1
side has an egg-shell paint finish, whilst the consultation side is covered with material. Strong colours, low-hanging lamps and chairs from the sixties create a cosy and inviting atmosphere to linger. Three light strips where corrective lenses are on show have been set into the display wall. The light puts them at the centre of focus and lends the room a feeling of depth and vitality. The glasses in the shop windows are on display inside glass boxes that continue the language of shape from the light strips. The illuminated coloured glass floor sets the scene for the models on the miniature catwalk.
Light to us is architecture, communication and design. Light design is oriented towards perception and must therefore serve the aesthetic design of the architecture. Light design visualises or communicates how architecture wants to be seen. Directed lighting is able to take social requirements into account by informing and orienting the viewer. Its implementation requires a certain proficiency in design. The interplay between an understanding of perception psychology, technical feasibility and economic efficiency is an exciting challenge.
Door manufacturers Doors & Doors in Mumbai, India, constructed a new building of 600 m2 for offices, warehouse and showroom. Urech Optik presents the latest eyewear fashion and organises events on a space measuring 20 x 4 metres. The two areas are intended to contrast and complement one another.
Light sells II: Doors & Doors Mumbai By Thomas Leroux, light designer at Regent Lighting Edwin Saldanha, director of Doors & Doors, came to see us at a trade exhibition. We recommended futuristic, high-quality solutions that impressed him so much he came all the way to Basel. His main objective was to adapt the lighting to the innovative and technological character of his enterprise. The light design process took place in Basel and produced a highly interesting solution: the design is the first to use Hello system lamps in the form of nested squares and fitted with fluorescent tubes and spot elements. Various level lighting elements (system, single and pendulum lamps) and foglia lamps were also used. The result is a perfect upvaluation of the room and a modern stage setting for doors by Doors & Doors.
«Swiss companies suit us best» By Edwin Saldanha, Director of Doors & Doors
As an Indian company we chose a Swiss lighting specialist to illuminate our showroom because the people at Regent Lighting do a very professional job. I am glad we did not decide to choose a cheap alternative. Light design must be unmistakable and suit the product. Regent has achieved that well. As door manufacturers we also work together with Hawa and have done so now for nine years. I got to know Hawa at a trade show in Dubai. Hawa is also an outstanding company. In my opinion, Swiss companies develop excellent technology. They suit us well. And the people are very friendly.

House L, Augsburg
Playing with light
An ever lighter, more transparent skin Architecture should be objective and purposeful, obey the laws of beauty by applying the rules of proportion, remain in touch with tradition without obstructing progress, said Swabian architect and master church builder Thomas Wechs (1893–1970). House L was awarded the Thomas Wechs Award in 2008. Small plot, close neighbours: House L in Doktorgässchen left no room for broad ideas, which is why Regina Schineis turned to lofty designs. Schineis worked with folding sliding shutters to let as much light as possible into the house despite the close proximity to neighbouring houses. «Folding shutters open up the entire west façade easily and as far as possible». Living space virtually extends outwards into public space when they are open.

House L Augsburg, Germany Architektenbüro Regina Schineis, Augsburg, Germany Sedlmeyr GmbH & Co. KG, Derching, Germany Gabriele Lindermayr, Augsburg, Germany November 2007 HAWA-Frontfold 20 Folding sliding shutters 10 systems with 32 elements Fibre cement panels
Schineis used three folding sliding elements facing south and also used folding sliding shutters for the French doors to the terrace which were only finished this summer. The Sedlmeyr company of Derching, responsible for façades and windows, installed HAWA-Frontfold 20 hardware. This hardware lets the folding sliding shutters slide gently and quietly up against the window front at an angle of 90 degrees; they take up hardly any space when folded and do not get in each other’s way, which is what makes so many windows possible in the first place. The shutters have a heavy influence on the appearance of House L. The Thomas Wechs Award 2008 is therefore going to a team of architects that not only knows about design options incorporating sliding systems but also how to skilfully implement them.
Open, slide, fold. A new house in the same location. A house that practices restraint and maintains a respectful distance to the neighbours. The heights and depths of the floors staggered from bottom to top. The entire house sustainable, in wood, breathing and natural.
Protected by a skin of fibre cement, coordinated shades of brown. An ever lighter, more transparent skin. Animation to open, slide, fold. As animating as life itself – an effigy. That life stands for today. Project description by architect Regina Schineis

Sliding and lighting Eating at the exhibition centre in Stockholm The exhibition centre in Stockholm is en route to success and has adapted its culinary offering to suit the change in requirements. The restaurant named The Parkside offers room for 850 guests. The giant hall has been redesigned and modernised to cater for varying requirements. Thousands of guests come to eat within a short period during exhibitions and conferences, but tables for two are also in demand for business meals.
Flexibility creates atmosphere The greatest challenge faced by architect Ivan Akabaliev lay in making the huge expanse flexible in use and the room itself light and airy. The solution consists of a mobile partition wall used to flexibly partition the large area into small zones. The Parkside could rename itself «Parkslide»; it is, after all, a prime example of the many other uses of sliding hardware systems: a sliding swinging door separates the room from the lounge, and a flexible wall separates the veranda area, where the restaurant opens up to the park through sliding doors.
«Freedom behind bars» Architects Office Rosenbergs opted for transparency and therefore selected glass as the dominating design element. Sliding glass walls create an aesthetic quality and enable the greatest possible flexibility. They can open partially or fully or remain closed, just as the situation requires. Room size, atmosphere and climate are all purposefully adjustable. Fasadglas, one of Sweden’s leading special-

Glass as a projection surface Switching on the light in The Parkside is much more than just pushing a button. The illumination concept complements the flexible room partitioning system and puts the people in the room in the best possible light. Coloursplashed walls define boundaries between rooms, milky frosted glass lets the light through but not the glances from outside. Light is staged throughout the restaurant to create atmosphere. Large chandeliers and spot lamps set into the ceiling illuminate the room. A chameleon-like «wallwasher» is available for creating special effects. The machine is able to generate millions of different shades of colour or white light through fluorescent tubes to immerse walls and furnishings in the desired colour tone. An asymmetric reflector projects a regular light image on the wall with no stripes whatsoever, creating a bright and friendly atmosphere. The glass walls can be used as projection surfaces for all kinds of images, and back-illumination also offers interesting variations. Staff control the light via touch-screens – even more convenient than pushing a button. 22 slide No. 1
Interior designer Ivan Akabaliev arranged the large area into various combinable zones. The restaurant is divisible into separate areas by means of a mobile partition wall with 53 glass panels. The lighting system is adaptable to suit the occasion and creates a light and airy atmosphere in the room.
GrugaCarree, Essen The assignment was crystal-clear: around 100 comfortable apartments on 6600 m2 and «unagitated yet unmistakable architecture» that encourages neighbourly interaction.
Insights and outlooks The result is just as crystal-clear: two L-shaped buildings that slide over and under each other in a shared corner and encase a large and bright inner park area. The park is designed with a circular pathway lined with pruned trees and French plant themes and offering furnished meeting points, green areas and a sandpit for playing – in brief: a place to linger. The face of the complex is defined by the loggias on the outside, which themselves are characterised by 170 sliding elements made of wood slats. They form a movable translucent filter in front of the loggias, define ever new outlooks and provide shade as well as screen against prying eyes. They lend a playful airiness to the otherwise relatively strict outer shell. It is not by chance these sliding elements glide on HAWA-Frontslide 60 hardware; it was specifically designed for outdoor installations, provides the greatest wind resistance (Class 6) and is highly resistant to corrosion. It not only makes the exposed outer fronts of the GrugaCarree airy and playful but also offers them protection.

Know-how
At some stage during this year, a specialist somewhere in the world ordered and installed a HAWA-Junior 80 hardware system. Perhaps in a sliding door, or for a room divider made of wood, glass or metal. He didn’t know that it was the three-millionth unit. He only knew it was a HAWA-Junior. He knew it would glide and glide and glide and glide. Quietly, softly and reliably.

HAWA-Junior 40
Plays two roles It is the lightest of the strong. It is of no relevance to a HAWA-Junior 40 whether the 40 kilograms it will spend its life moving quietly and reliably are made of wood or glass. The main thing is that it runs and runs, moving the door to and fro on two quiet plastic wheels with maintenance-free sliding bearings.
HAWA-Junior 80
Sliding is everything It has been the reference object since 1983. Continuously developed and with complementing variants and expanding weight categories. HAWA-Junior 80 runs quietly, softly and reliably. Stylish variants for glass doors with continuous profiles or patch suspension are all the fashion in the weight category up to 80 kilograms.
HAWA-Junior 120
Let it glide Let glass, wood and metal glide as if on tracks: HAWAJunior 120 makes it possible. This sliding hardware is also available with various suspension methods, accessories and designs. Take, for instance, HAWA-Adapto 80–120 as an example from the accessory range: the concrete casting profile lets the top track disappear into the ceiling.
HAWA-Junior 160
Only floating is lighter 160 kg of smoothness moved with ease: the high-quality plastic wheels in the trolleys of every HAWA-Junior 160 are equipped with tried and tested sliding bearing technology. The floor guides on every type of HAWA-Junior sliding hardware are rattle-proof, and the track stops keep their promise every time.
HAWA-Junior 250
Moving heavyweights lightly Whether in restaurants, hotels, banks or shopping malls: HAWA-Junior 250 is capable of sliding even large-surface glass fronts with soft smoothness. The same applies to classic partition walls made of wood, for instance in office complexes, multi-purpose rooms or clubs. A lot of style moved with little effort: HAWA-Junior 250 is just like its little sisters. But much, much stronger.

Of course, sliding hardware is also subjected to a number of tough internal endurance tests.

The exhibition glasstec will take place in Düsseldorf in October 2008. Hawa AG will be presenting its new glass hardware system HAWA-Telescopic 80/G. The clou: the glass sliding door is twice as wide as the recess in which it is hidden.

be twice as wide as the recess thanks to the space saved through the parking solution. HAWA-Telescopic 80/G will thus also feel at home in tight environments, i.e. precisely in those locations where transparency makes rooms seem bigger: in kitchens, bathrooms and offices. The new hardware is based on the smooth-running HAWA-Junior 80 system, which is why both doors move effortlessly, softly and quietly despite weighing 80 kilograms each.
What is running so smoothly? Everything. The fibreglass-reinforced toothed belt is not subject to troublesome extension and is form-fitting in transmission – no slack or slippage. Last but not least: the retention spring of the track stop is steplessly adjustable to any door weight so that the door always stands still whether open or closed. After all, the system should be as safe when immobile as it is agile when moving.

Dubai – Orient in the fast track
«I found it somewhat pompous at first», said tennis champion Roger Federer of the seven star hotel Burj al Arab in Dubai. But he came back time and again. Dubai attracts people from Switzerland. Dubai is building, and the Swiss are building with them.
Standing at 818 metres the Burj Dubai (Tower of Dubai) will be the tallest building in the world.
Record-breakers Master builders in Dubai are collecting world records like pearl collectors once gathered oysters: soon to be opened are the 6,500 rooms of the «Asia Asia», the world’s largest hotel and, together with 50 other luxury hotels, part of the new Bawadi district in the retort city Dubailand. Dubailand is being built on 140 km² of desert which is destined to become the world’s largest Urban Entertainment Center with the world’s largest amusement park, largest roller coasters, largest shopping mall and...

Tourists instead of oil The natural oil reserves that have made the former colony of pearl-divers and fishermen grow rich since 1966 will presumably dry up around the year 2020. Dubai is even smaller than Rhode Island, the smallest state of the USA. The Emirate is banking on trade, finance and tourism with growing success: oil’s contribution to the gross national product has sunk to below 10%. Palm Jumeirah: 2,500 apartments and 1,400 villas were sold within 72 hours. In purple on the right: Burj al Arab, the landmark of Dubai.
«Burj al Arab», opened in 1999, is considered as the city’s landmark due to its sail-like sha pe. At a height of 321 metres it is as high as the Eiffel Tower. However, the Swiss tennis star no longer stays at the «seven-star hotel». He bought himself an apartment on Jumeirah Beach in 2005. Around 1,300 Swiss nationals live in Dubai. They are much appreciated by the Emirati, who consider Switzerland as an ideal country with a stable form of government. Switzerland exports products worth just under 2 billion Swiss Francs to Dubai every year, but only imports products to a value of around 340,000 Swiss Francs, mainly products relating to natural gas and oil.
Sliding hardware for the Burj Dubai are packaged at Hawa and transported by ship.
The people Ten years ago Dubai counted less than 200,000 citizens; today, more than 1.4 million people live in the emirate, with 85% of them living in the country’s capital, Dubai City. 85% are foreign nationals, many of whom are Asian labour immigrants. 75% are male, again due mainly to labour immigrants. 4.6% are dollar millionaires.
Well-established relationships Swiss companies based in Dubai usually work very successfully, says Swiss consul general Gerhard Brügger to Swiss newspaper «Schweizer Arbeitgeber»: «Relationships with the Emirati are often of long standing, and this is reflected in the business results.» Hawa Middle East FZE, founded in 2005, is enjoying an annual growth rate of 40%. In the meantime regional sales manager Adeeb Ghazal has added two new members to his team. Customer satisfaction has become a byword since the first Hawa hardware systems were taken into service. Product quality and relationships are decisive factors in the Emirates.
Satisfied customers always come back. Hawa hardware can be found everywhere. HAWA-Symmetric 80/Z synchronous sliding hardware is installed in 900 apartments at the heart of The Old Town. Cabinet doors in 1,700 villas on Palm Jumeirah, the first of three artificial islands off the coast, glide with HAWA-Multifold 30 folding sliding hardware.

2015. Dubai International Airport processes 70 million passengers per year, around about the same number as London Heathrow. But the world’s largest airport is already under construction. Capacity: 120 million passengers per year.
Speculative property market Experts on Dubai consider the property market as extremely speculative. New buildings often change ownership even before the first occupancy, and vendors can achieve profits of up to 50%. Demand is huge, and the city breathless.

HAWA-Junior 80
Glass suspension and retainer profiles now in plain anodised
Successful start for the invisible hardware
Calculation and planning aids now with installation width
New track stop with enhanced corrosion protection
HAWA-Variotec is characterised by sophisticated movement and curving technology and offers total convenience for glass sliding walls weighing up to 150 kg. Plastic-coated rollers run smoothly and quietly in anodised top tracks. Materials testing institute LGA in Nuremberg put the system through a test of 250,000 cycles and observed virtually no signs of wear but every indication of excellent running properties. The system looks elegant as there are no visible working parts. All components are integrated in the glass suspension and retainer profile, which is mounted to the glass and imitates an optical division. Retainer profiles and glass suspension and retainer profiles that hold the glass in sliding pivot and sliding swing doors are now available from the warehouse in plain brushed aluminium. Lower costs are the result and shorter delivery times guarantee timesaving installation.
The new hardware for all-glass doors was launched on the market in spring 2007. Very successfully. Because it has turned the design ideal of an invisible hardware system that enables a totally transparent room design into reality. The innovative system hides its technology in the top tracks. A growing number of architects, planners and designers are using HAWA-Puro to give their sleek and elegant language of shapes a perfect finish. The top tracks can be set in concrete ceilings (using the HAWA-Adapto concrete casting profile) and mounted flush to suspended ceilings. The ceiling joint profile enables the installer to fit the suspended ceiling quickly and easily. A neat and perfect detail from a design viewpoint. Another innovation is Hawa’s patent-pending wedge suspension which allows doors to be fitted and height-adjusted in recordbreaking time.
HAWA-Aperto 60/H is the first system designed specifically for light-weight wood partition walls of up to 60 kg in parallel and 90° layouts. The closed wall has a flush front and requires only little stacking space when opened. HAWA-Aperto 60/GL is the equi valent for glass. Installers can plan and fit standard systems themselves thanks to sophisticated technology and a standardised system, a much more costeffective method than customised production in the factory. A simple article structure guarantees speedy delivery of any component at any time. Clearly-arranged calculation aids and instructions to assist with planning and installation are available online at: www.hawa.ch --–> HAWAProductfinder. Installation width was integrated as a response to the many requests received and it is now easier to calculate additional variants.
Hawa pays due attention to another detail to guarantee longterm sliding convenience. Top track stops are now galvanised. The result is a resistant coating that protects the metal against corrosion, even under heavy use. Installation dimensions, functions and all the other benefits of the track stop remain unchanged: the roller gently glides under the a retention spring at the end of its journey which prevents it from rolling back and which is adjustable to suit the weight of the door. A rubber bumper gently stops the door and keeps the sliding experience pleasing to the ear. The stop body is punched from steel and fastened with stainless steel screws in V2A quality. The new track stops fit all products based on HAWA-Junior 80, which means they are also suitable for HAWA-Telescopic 80 and HAWA-Symmetric 80.
