Energy efficiency and renewable energy take center stage of the exhibition in the Welios Science Center, Wels, Upper Austria. In order to reflect the basic idea of the building also on the facade, LED-elements with integrated photovoltaic panels which serve as a power station during daytime were installed on the south and east side of the building. As a matter of fact, there is no visible difference visible between these combined modules and the standard RGB LED-bars when the lights are switched on. Because the average energy consumption of the single-coloured nighttime LED lighting does not exceed 3kW, it is completely compensated by the approximately 3,3kW of power produced during daytime.
Energy Lines symbolized through LED-elements
Each single module of the approximately 700m of the so-called Energy Lines was installed directly onto the façade with a simple mounting support. The basic idea to take up and reflect the topic of the whole building on the façade as well as the conceptual design and outlay of the Energy Lines originates from the Archinauten team of architects, Linz, Upper Austria.
These 700m of Energy Lines are to about two-thirds built-up of standard modules with 2m length and straight ends, the remaining modules have been modified and adapted to match the building’s edges. Due to the special design of the substructure of the LED-modules all the necessary cabling could be laid underneath these modules, thus making it possible to install them closely together without any gap. Because each single LED Line can be controlled individually, it is possible to create smooth colour fades and shades all over the complete façade.
Uncomplicated visual covering
The complete lighting system of the façade with its 40000 RGB-LEDs is controlled by a Show Controller, which contains the light shows created by Multivision. With this Show Controller, it is very easy to select the desired lighting programs and shows either with the touch of a button or via the house automation system. The main advantage of this system is that the house technician can make use of the full features of the lighting system using a control system he is familiar with, so there is need to learn to use a completely new system.
Lightening for special demand
A special challenge was the design of the lighting of for the walkway in the passage area. The requirement was to have a light which was weatherproof, shock proof and nearly indestructible. The solution was to design and build single 40cm high acrylic blocks in which the LEDs are imbedded and fully molded. Because of the position of the LEDs inside the acrylic block and the resulting diffusion of the light a lamp could be realized which not only fulfills all expectations in respect to the operative conditions but also provides perfectly homogeneous light with an installation depth of only a few millimeters.
Multivision successfully completed this project with the support from the Archinauten team of architects and from the E-Werk Wels power company, who was responsible for the installation of the LED modules. The individual Energy Line LED-bars were developed and produced by Multivision in cooperation with Ertex Solartechnik GmbH. The concept and the programming of the media display of the façade was completely done by Multivision.
