Sunways Supplies Solar Facade for New RENA Building

published: 2012-03-30 15:22

A new administrative building for RENA GmbH is being constructed in Gütenbach/Germany. The equipment manufacturer, which produces machines for the wet chemical processing of substrates used in solar, semiconductor, medical and circuit board technology, is currently expanding its headquarters in the Black Forest with a modern new building that boasts trendsetting architecture.

The highlight of the construction project is a solar facade supplied by Sunways AG that is approximately 600 square metres in size. The electrical connections for this facade were also designed by Sunways. The photovoltaic provider based in Konstanz is a leading solar technology company. The futuristic building envelope combines aesthetics and functionality, design and energy production. Coloured solar cells add a unique touch and provide green power. All in all, the facade delivers a peak electrical output of 54 kilowatts. 

Thanks to this project, Sunways has demonstrated yet again that sophisticated, multifunctional solutions are the answer to energy-efficient architecture. In Gütenbach, glass-glass modules in different sizes and shapes are installed at a height of up to four storeys. The modules are fitted with 6-inch emerald solar cells from Sunways. The intense colour and multicrystalline surface structure create vibrant colour gradients. Due to the arrangement of the solar cells in the modules the interior is flooded with natural light. At the same time, the partial shading of the facade helps regulate the indoor climate.

In addition to its unusual appearance, the facade has another impressive feature: the frameless glass-glass modules come without conventional mounting. The modules are attached via point fixings that are cut into the rear panes. The solar cells and front panes are laminated using plastic films. From the outside, this creates the impression that the modules are floating. Sunways commissioned Ertex Solartechnik GmbH in Amstetten, Austria, a partner with which it has already successfully implemented several projects in the past, to manufacture the building's customised glass modules.
