Glass Architects, designers, and artists appreciate natural materials. Their unmistakable appearance and haptic features fascinate both users and observers. In this connection, glass also moves into focus - a material whose diversity and emotional potential distinguishes a range of widely differing building projects.

Glass | 5

It is single-colour, multi-colour or completely colourless. Highly refl ective or shimmering matt. It can be polished, engraved, etched, printed or sandblasted … There is absolutely no doubt that the mixture of quartz sand and other mineral raw materials has proven to be a material with a large choice of variants that is used for a huge variety of purposes.

Glass has been impressing people for 9,000 years now: even back then, obsidian, a type of glass that was produced naturally in the course of volcanic eruptions, was used for tools such as wedges, blades or drills due to its high degree of hardness. Naturally, it was a long way to go until glass was produced by melting and forming. The oldest glass container that can be dated with certainty was produced in Egypt in approx. 1450 B.C.

Indispensable today in the window manufacturing sector, glass possesses an unlike greater aesthetic potential: especially in facade construction, glass is captivating mainly due to its transparency and its ability to communicate with its surroundings by means of refl ection.

Benefi ts of glass• Versatile interior and exterior application is possible• Wide colour spectrum• Wide range of surface fi nishings possibilities• Ecologically compatible building material• Durable and easy to clean• Robust and weather-resistant• Backlighting can be employed• Refl ects its surroundings

Real beauty survives for thousands of years

Architecture with glass: leaded glass windows have been widespread in Europe since the middle of the 11th century.

Glass is not only a remarkable material in terms of its appearance, but also due to its fl exibility and durability – its life span is impressive. Glass facades are as weather-resistant as they are easy to take care of: rain, snow, and ice are unable to damage them. Glass is easy to clean, requires only little maintenance, and can be recycled. A further plus point in relation to sustainability: in the opaque StoVentec Glass system, even the carrier boards are made of 96% recycling glass.

Sustainability is the best policy

Sustainable material: glass is extremely hard-wearing, weather-resistant, and up to 100% recyclable.

10 | Expert interview

Expert interview Due to its properties as well as to its diverse areas of application, glass is probably the most sophisticated building material for architects. It is not the material itself that is so fascinating, it is the possibilities it offers as a composite material. Martin Haas, in the course of his activities as a partner at Behnisch Architekten, has gained a lot of experience with this building material. A brief insight into why his offi ce likes working with glass.

Expert interview | 11

Sto: The construction of a glass facade is more complex than that of a massive brickwork facade, the costs are higher and the climate of the interiors is more diffi cult to regulate. What induces Behnisch Architects to use glass on a large scale nevertheless?Martin Haas: Transparency and lightness, the unobstructed connection between the interior and exterior, the possibility of creating open, inviting rooms are signifi cant aspects of our architecture. The wonderful view, the shadows of passing clouds on walls and fl oors are features of high-quality rooms and the basis for creating an architecture that enriches the everyday life of the user. Glass infl uences work in our offi ce in a way barely any other building material does. Refl ections and light refractions on opaque glass surfaces allow for exciting designing possibilities. In our project in the Chamber of Commerce in Hamburg, we were able to give the whole building an almost immaterial appearance.Sto: Glass as such has been explored as far as possible, whereas the possibilities of the further development of glass as a composite material are seemingly unlimited. Chromogenic and electrical chemistry, aerogels, nano technologies are specialised terms based on complex sciences. As an architect, how do you keep up with the latest state of the art?Martin Haas: For us every project begins with a basic analysis, also of materials. We often develop new possibilities of application in cooperation with manufacturers, for example the LED tech-nology for Unilever. This way we automatically keep up with the state of the art in technology.Sto: For a long time it was especially the available maximum size of individual glass panels that was the primary problem for manufacturers, whereas today it is, above all, questions con-cerning energy that have to be answered. In your opinion, what is the energetic potential of glass as a composite material that has not yet been fully exploited?Martin Haas: The topic of "sustainability" has been infl uencing the way and manner we have been developing architecture for some time now. The extravagant use of glass as a the dominant building material in facades has been under some criticism from an energetic aspect. Glass still has invaluable benefi ts in light of the possibilities of different building materials and on consideration of the climatic impacts of a specifi c building site as well as the

orientation and alignment of a building: the unobstructed visual link to the exterior and the optimum exploitation of daylight in the interior is achieved by no other building material. Heat loss in winter as well as undesirable solar heat gain in summer can be controlled more easily by new technologies like vacuum or triple glazing or a more effi cient sun protection system. When employed in accordance with these features, glass is an irreplace-able building material especially in ecological architecture.Sto: Many architects dream of the "intelligent skin": glass that not only provides protection, but that can also communicate – much of this can already partially be achieved, other concepts are still a vision. What innovations are you hoping for for the future?Martin Haas: One goal is to reduce the number of materials and trades in a building and to simplify its actual construction. However, this would entail a revision and re-structuring of lighting concepts. A new aspect here is the option of utilising the facade not only as a source of daylight, but also as a source of artifi cial light. It is a worthwhile notion to replace the slowly disappearing daylight with artifi cial light in the same element in the evening hours. A room situation optimised to a specifi c light situation would function both during the day and in the evening. Therefore , the facade of the future does not only provide protec-tion from the sun, solar panels for energy generation, defl ecting elements in the top area of the facade for daylight control and elements that can be opened for ventilation, but it also includes lighting elements for basic lighting at night as well as heat exchangers and elements for mechanical 2-way ventilation. Moreover, we also see a lot of structural, material-saving benefi ts: the facade, as a technically complex and precisely crafted element, has a pre-installation from the onset due to the control elements such as solar protection that can also be used for lighting fi xtures.

14 | Inspiration

Inspiration Already the composition of the individual elements leaves a great scope for creativity. Moreover, the arrangement of the elements or the combination with other materials opens up unlimited design possibilities. And not only on the facade.

Inspiration | 15

Creativity lies between the lines

As the size of facade panels is limited, joints between the single elements cannot be avoided. However, this does not necessarily mean a "break" in the design. Joints can have a separating, organising, structuring or rhythmic effect and thus lend a special quality to a building. The creative use of this fl exible "void" has long since been a topic in architecture. Joints can run horizontally or vertically, vary in their width, be arranged symmetrically or asymmetrically.

Huge range of variants: only three examples of how joints can be used to create appealing facades.

16 | Inspiration | Joints

Euston Road, UK-London, Sheppard Robson Architecture, UK-London Inspiration | Joints | 17

Sometimes it's all about the mix. Different materials and surface textures make balanced facade designs possible. The combination of glass with natural stone or render on a continuous sub-construction creates either separation or a link. The alternation in material sets accents and formulates citations. Different types of glass and panels, a large range of natural stones as well as an almost unlimited choice of organic or mineral render textures in all the 800 colour shades of the StoColor System allow for a multi-facetted interplay of haptic and visual features.

A special variant of this interplay is the combination facade, in which not only the surface changes, but also the underlying system; for example in the linking of RSC with a classic EWIS. Sto provides numerous connection details to achieve this.

Together they are strong

In the system: from glass to natural stone – changing the material without changing the system.

The fact that StoVentec Glass facades are resistant to storms and cold temperatures and still cut a good fi gure is one thing. But StoVentec Glass can also be used in the interior of a building where it is protected from the impact of the weather. With one and the same system, StoVentec Glass guarantees a continuous material fl ow from the exterior to the interior.

22 | Inspiration | Overhead glazing

StoVentec Glass has also been tried and tested in overhead glazing. Sto places the highest demands on safety and quality: as the carrier board and the glass panel are bonded to form an inseparable sandwich panel, there is no danger of glass splinters falling down if the glass is damaged. This allows for overhead glaz-ing both on the exterior and in the interior of a building. With appropriate planning, functional elements such as lighting can be integrated without any problems.

24 | Material variants

Material variants StoVentec Glass Panels are customised pieces which are predominantly produced manually according to the wishes of the customer. In terms of shape, colour, or fi nishing techniques, the range of designs is impressive.

Material variants | 25

StoVentec Glass Panels are not available "ex warehouse". They are customised pieces that are manufactured individually according to the construction project and wishes of the customer. This is accomplished at the Sto panel production facilities in Lauingen, predominantly according to good, traditional craftsmanship. This allows for a wide range of special shapes extending to panels with cut-outs for functional elements.

The carrier boards for the panels are also made in Lauingen. These consist of expanded glass granulate, an environmentally friendly material that is obtained to 96% from recycling glass. First the boards are cut to the required format. The edges are sealed by hand in the course of several work steps. The agraffe profi les are then screwed to the rear of the carrier boards, the glass panes are mounted and grouted.

On the construction site, the panels are suspended from the sub-construction without extensive time investment and regardless of the prevailing weather conditions.

Precise craftsmanship

To the millimetre: this is where the StoVentec Glass Panels are cut to their individual format.

The individual character of a building facade is not only unfolded by the interplay between colours and shapes, but also by the specifi c surface design. Also in this case, StoVentec Glass facades prove to be an ideal projection screen for a huge range of ideas. Screen printing offers multiple possibilities for surface refi nement. Almost any desired motif can be applied to the rear side of the glass panels using this procedure, whether these are patterns, illustrations, photos or corporate logos.

StoVentec Glass Panels are available in many different forms. For example, panels can be supplied in square, rectangular, trapezium, and parallelogram shape. Due to the non-visible, mounted suspension system, only fi ne joints structure the homogeneous surface area – entirely without frames, rails or point brackets. The panels also bear up to any critical inspection from close proximity thanks to their customised production. As the distance to the wall of the building can be adjusted precisely, the StoVentec Glass Facade system also enables levelling of potential unevenness.

Systems The StoVentec Glass Panels naturally leave a good impression at fi rst sight. With StoVentec Photovoltaic, the facade even becomes an electricity supplier. But the inner values are also convincing: the sub-construction reduces thermal bridges and consequently the insulant thickness. And the rear ventilation provides even more benefi ts: optimum protection against noise, cold, heat, driving rain, and moisture.

The concrete technical specifi cations and information on the products contained in the Technical Data Sheets and approvals must be observed.

StoVentec Glass is a ventilated rainscreen cladding system consisting of a sandwich element, thermal insulation, and a stainless steel aluminium sub-construction. This can be mounted onto virtually all bearing walls. A circulating air layer remains between the suspended panels and the mineral wool insulation mounted directly to the substrate. In this way, a wall structure which is optimal in terms of building physics with thin construction depth is achieved.

The tempered safety glass is completely adhered to a carrier board to produce an inseparable sandwich panel. This rules out any risk of pieces of glass dropping from the facade, even in the event of glass fracturing.

The carrier board itself is made of expanded glass granulate, a material that is as light as it is environmentally friendly since it is obtained from recycling glass. With a weight of approx. 30 kg/m2, the system is light enough to be employed in older existing buildings.

The suspension of the 30 mm thick glass modules on the rear side is non-visible. The modules are available in all required dimensions up to a size of 1250 x 2600 mm. The individual panels are factory-produced according to the individual specifi -cations for simple attachment to the sub-construction on site. Oversized formats are possible in individual cases with special approval.

This is how facades are energised

Photovoltaic, the direct conversion of solar energy into electricity is one of the most environmentally friendly methods of generating energy – no exhaust gases, no consumption of fossil resources. With StoVentec Photovoltaic, this technology can even be used via the facade. Developed in close cooperation with Würth Solar, a special photovoltaic module is integrated into the facade as a surface. StoVentec Photovoltaic does not only insulate the building and reduce its heating requirements, it also generates energy from solar radiation at the same time.

The modules can be supplied in six different colour shades. The degree of the light refl ection has an impact on the effi ciency. Depending on the colour, an annual electricity yield of 45 - 75 kWh/m² of photovoltaic module can be generated. This means that with a StoVentec Photovoltaic Facade of 60 - 100 m2, the average energy requirement of a Central European family of four can be covered.

At the factory, the photovoltaic modules are bonded with the StoVentec carrier boards to form sandwich elements. They must be suspended from the sub-construction and connected to the inverter. The active PV modules are available in the sizes 1200 x 600 mm or 600 x 1200 mm; in case of the maximum possible panel format of 2600 x 1250 mm, several PV modules are bonded onto a carrier board.

But the visual experience is not neglected in the face of environ-mental friendliness and cost-effectiveness: all colour shades of the StoVentec Photovoltaic Panels are supplied with a pinstripe effect, which creates an aesthetically appealing design.

Facade system meets eco system: Palma Aquarium, Palma de Mallorca

"Aquarium" appears to be a sheer understatement for the structure in Palma de Mallorca, located in the western part of Playa Palma. Erected in 2007 on a site of 42,000 m2, the building complex accommodates 55 aquariums, each a living marine ecological system. Around 8,000 specimen of more than 700 different marine creatures from the hammerhead shark to the sea cucumber splash about in 5 million litres of water – a conservation of endangered species of marine fauna and fl ora. Even the architecture gives the impression of a living organism, instead of a rectangular geometry with edges and corners, it is organically and dynamically bent in its structure. It was a real challenge also with regard to the facade system, but it was mastered by using StoVentec Glass. The system proved to be an ideal solution also in this unusual context. Because the even, rectangular elements can also be employed in bent and "sweeping" layouts. Manufactured in the matching sizes, the coloured glass panels can be fi xed to the rear side thanks to their non-visible agraffe profi les.

The entrance building is designed with glass panels in different shades of blue.

The future has an antiquarian feel:Archive of the State Archaeological Museum, Schwerin

Erected from 1859 - 1862, the buildings of the "Old Artillery Barracks" in Schwerin are for the most part in good shape and are currently used by local authorities. The riding hall is a different matter: this hall was actually supposed to be converted into a sports hall – until the construction project was stopped, leaving a dilapidated brick ruin behind. It wasn't until a few decades later that this ruin was secured against collapse by the Landesdenkmalamt (State Offi ce for the Protection of Historic Monuments) and presented with an unlike neighbour on the other side: a "Black Box" of glass which accommodates the State Archaeological Museum. Designed by the architects of the State Building Authority Mecklenburg-Western Pomerania, the monolithic, shining black cube exhibits neither windows nor any other visual differentiation apart from its entrance side.

The building was constructed as a reinforced concrete construction with external walls of lightweight bricks, in front of which was installed a ventilated rainscreen cladding StoVentec Glass facade consisting of black enamelled glass. The contrast between the Black Box and the brick masonry could not be greater; at the same time, though, it combines the past and present to form an ensemble.

This is not only the opinion of András Petö, on which "Learning with therapeutic support" is based and practised in the School, Boarding School and Support Centre for Children with Disabilities. It is also the opinion of the RPM Architects' offi ce, whitch designed the building with this requirement in mind. Especially eye-catching are the colourful facades of the building complex: whilst the translucent surfaces shimmer in green and blue, the opaque parts shine in yellow, orange, and red. A friendly and cheerful atmosphere where the children feel at home is created by this mixture of materials and colours.

The capital city of Styria, Graz, is not exactly famous for wild jungle animals. But there is a "Black Panther" at the Liebenauer Tangente. Anyway, this is what the MP09, the offi ce building of an optics company, is known as by the natives and staff. And, in fact, its mysterious dark gloss makes the building, resting on its bases with the spectacular protruding bow, look like a panther ready to pounce. The Graz-based GSarchitects designed an architectural sculpture that is intentionally conspicuous in its urban environment. In the words of GSarchitects, "Architecture can be anything: functional, pragmatic, poetic, urban, or aesthetic. For us, the MP09 does not only have a bit of all these features - it's got it all.”

The dynamic quality of the architecture is enhanced by the use of StoVentec Glass: the black glass panels refl ect their environment, which is continuously in motion. People, traffi c, clouds, the course of the sun – the building itself is a platform for a continuously changing drama.

Working on the sunny side:Manz AG, Reutlingen

Reutlingen is regarded as the "Gate to the Swabian Jura". The work of the local company Manz AGconstitutes a gate to future-oriented energies: Manz builds machines with which solar cells are produced. What could be more natural than integrating photovoltaic into the architecture of the new customer centre? Hence the visually striking stair tower was fi tted with StoVentec Photovoltaic solar modules. Across a surface of 160 m2, solar energy is converted into electricity – simultaneously, a contribution is made to environmental protection and is evidence of a corporate mission. Developed in cooperation with Würth Solar, the facade system is not only distinguished by its energy-technical but also by its aesthetic qualities: the dark shining pinstripe-patterned modules form a visual contrast to the shining whiteness of the rest of the facade. Designed by the Hank + Hirth architects offi ce, the customer centre forms the focal point of a whole ensemble of production and offi ce premises and provides space for offi ces, conference rooms, a canteen, and a spacious production hall.

Therapy against dullness: Lausitzer Seenland Klinikum, Hoyerswerda

54 | Projects | Lausitzer Seenland Klinikum

Included in the essential requirements in the caring and nursing area is a high degree of functionality that should not exhibit the typical hospital atmosphere.

A combination of these requirements is demonstrated by the clinic in Hoyerswerda, Saxony: the extension and refurbishment of the building complex includes the new construction of an examination and treatment centre over six levels that is out of the ordinary. It was implemented with StoVentec Glass. Sun protection glass was used both for the fl ush-mounted windows in the front and the glass facade, achieving an even surface. The glass facade tilts forward by approx. 4 degrees towards the top of the building, providing an unusual picture for spectators. The lateral, downward tapering closures have been accomplished using trapezium-shaped glass panels. The highlight here is the rectangular "glass body" on the roof of the building: not fl ush but consciously arranged in an offset pattern, it protrudes prominently into the air.

Where worlds meet:Cultural Centre, Schönsee

Schönsee is a quiet place not far from the German-Czech border, where a project has been implemented that is committed to the meeting of different cultures. The "Centrum Bavaria Bohemia" is accommodated in the former community brewery: until the 1950s, the families in the town used to brew their own beer in the building, which was built in the 17th century. Today it is not just different cultures meeting there, but also different worlds of materials: the printed panels of StoVentec G have been mounted to the original stone walls.

The Brückner & Brückner architects's offi ce, which was commissioned with the refurbishment, added another storey to the eastern wing by integrating a reinforced concrete core into the old walls on which the glass facade could be mounted. The 120 x 21 cm sized panels pick up the patchwork structure of the old masonry: they were arranged in a stretcher bond and a photo of horizontally layered glass panels was printed onto them. A double abstraction that blurs the border between material and construction.
