Insulated BIPV facade & roof
Custom-designed glass-glass-modules
Modern office building
Sustainable working in a modern office building with a pleasant atmosphere. The facade of the central entrance area as well as the atrium were equipped with translucent, individually adapted solar glass modules. The individually manufactured glass-glass modules are integrated into the building envelope and serve as roofing, shading and energy supplier. Since the modules are designed as double insulating glazing, they have excellent thermal properties. At the same time, their transparency ensures sufficient light to pass through for a light-flooded interior.

Black BIPV facade
Modern energy generating facade
Elegant look
A frameless photovoltaic facade has been adapted individually to an existing building. The result is an elegant, power-generating facade that is not recognizable as such at first glance. 399 glass elements in 15 different sizes and geometries were optimally integrated into the existing building structure. The use of integrated diodes optimizes the yield of this BIPV facade.

Design roofing of an underground parking entrance
Light-flooded and sustainable
Integrative design solution
The private client of this special underground parking entrance was looking for a bright and sustainable solution for the roofing of his entrance that blends into the surroundings harmoniously and at the same time satisfies his desire for a special design solution beyond standard ideas.
Distinctive shadowing
For an ideal integration into the surrounding nature a green substructure was provided for this underground parking entrance. Matching semi-transparent glass-glass modules with emerald green design cells were created for this purpose. Viewed from above they perfectly embed themselves into the overall picture. The entire design-potential, however, is only visible inside the entrance – the distinctive and impressive play of the modules' shadowing is created in the sunshine.

Multifunctional building envelope in corporate color
Blue glass facade with LED elements
Innovation and sustainability
The company Omicron was looking for an innovative and sustainable facade in the colors of their logo. With this in mind, a very elegant glass facade with „blue“ as the main color was designed, in which highly efficient solar cells were embedded. The technical affinity and innovative strength of the company are reflected in the integrated LED glass elements in corporate colors.
Implementation
This multifunctional facade consists of 510 glass-glass elements and 90 LED glass elements, which are specifically authorized for a vertical assembly in facades. All elements are individual, customer-specific designs, which optimally integrate into the building structure in terms of geometry, size and structure. One particular highlight is the specially programmed LED play of corporate colors, which has been attached by means of LED stripes that are attached to the rear side. This spectacularly sets the facade in the limelight during night. The production and installation took approx. 6 months.

Facade construction
The substructure consists of approx. 1,000 extruded profiles and more than 1,200 retaining brackets, which have been anchored in the wooden wall. The glass elements have been attached to the retaining brackets in structural glazing with 2-component-silicone and were individually mounted on 4 points in so-called bolt slides.
Curved facade elements
Adaptive design to achieve maximum integration
Futuristic Design
The new office building designed by the Architekturwerkstatt Vallentin was implemented according to the passive-plus-energy house standard. It excels through its futuristic design and the combination of down-to-earth and innovative materials. One remarkable design element are the striking, individually designed photovoltaic facade elements, which have been attached to the railings of the floating corridor.
Sophisticated details
One particular feature of the semi transparent BIPV modules is the finishing of the rear side of the modules by means of selective screen-print. By imitating the front cell optics, the module surface visible from the inside ideally integrates itself into the design concept. The highlight, however, are the two curved photovoltaic elements on the curved structure of the triangular shaped atrium. The approximately 3m² large glass-glass modules are bent in a radius of approximately 3.5m. By means of their adaptive design, they perfectly harmonize with the building line and optimally blend into the overall design.

Construction
The large-scale photovoltaic glass elements were installed into a custom-made metal frame construction. Thanks to the space saving positioning of the electrical connections on the edge of the glass, the connecting cables could be installed invisibly in the frame construction. The electric cabling of the PV facade glass was installed horizontally within the frame construction.
Exclusive gas station roofing
Transparent and roof-integrated
Gas station of the future
The initiator of this project, an ecologically committed operator of a major gas station chain, aimed to transfer the subject of environmental consciousness into the market for fossil energy. The assignment here was to design an exclusive, design-oriented roofing solution with integrated photovoltaic.
Transparence, protection and communication
Project-specifically manufactured glass-glass elements have been installed as an integrated roof on different stations. Due to the transparent appearance of the solar modules, open, light-flooded, yet protected areas have been created to place the design element of photovoltaic into center stage. The ideas „renewable energy“ and „climate protection“ have been integrated and communicated into the world of gas stations in an intelligent way.

Construction
A customary roofing system made of aluminum profiles, in which the photovoltaic glass elements are embedded, has been installed on the steel construction. The installation does not differ from the conventional installation of flat glass elements. The electrical wiring/cabling is located in the fold of the aluminum profiles. The entire installation was carried out by Rudolstädter Systembau, a metal construction company with great experience in the field of gas stations. The planning of the electrical wiring of the PV glass elements was carried out by SUNOVATION.
Black design facade
Elegant appearance with added value
Homogenous and straight
The building developer of this special object had a precious, homogenous looking glass facade with the special something in his mind. The focus of the conceptual planning was the uniform black appearance of the facade that serves to accentuate the clear lines of the building.
Glass-glass modules instead of thin-film
Initially planned with thin-film modules, this facade was realized with glass-glass modules. These do not only offer the requested homogenous dark surface, but due to the crystalline solar cells also generate a higher yield. On top of that came the adaptability of the facade elements to the special requirements of the specific architecture of the building. For this project a total of 330 photovoltaic and décor facade elements with approx. 20 different dimensions were individually produced and installed.

Multi-functional facade of an office building
Insulating glazing with additional benefit
Straight and rich in contrast
The building developer of this project is a specialist for building envelopes and planned a solution which meets his ideas for the design. The goal was to design an insulating glazing with integrated photovoltaic, which adequately picks up the straight, design-oriented style of the metal facade.
Building envelope with additional value
The special character of this insulating glazing with integrated photovoltaic reveals itself to the viewer particularly in the inside of the building. There the visible solar cells are responsible for the specific shadow play and hint at the idea of subject sustainability. By means of the partial shading an overheating of the interior space is avoided. The 2-fold insulating glass ensures the necessary thermal insulation, while the monocrystalline high-performance cells create electrical power.

Industry facade of a different kind
Glass-glass modules with integrated LED lighting
Modern industrial building
The simple industrial facade was supposed to innovatively represent sustainability. A unique solution was developed to add value to the industrial building in a modest but effective way.
Spectacular distant effect
During the day this glass facade is impressive due to its photovoltaic cells. However, the integrated LED lighting is the highlight of the construction. At night the facade is illuminated with bright light and thus impresses with a spectacular distant effect.
