Graz (29.08.2014): The residents of the old town in Graz can now harvest the sun. Today a new product innovation comes on the market for protecting the listed rooftop landscape in Graz, which can make technologies such as solar panels appear invisible behind a special glass surface.
SKIN®energyroof are a new type of glass shingle from SFL technologies GmbH and cover dark solar and photovoltaic systems underneath. When looking down from the castle mountain or neighbouring buildings, these installations are perfectly integrated and almost indistinguishable in the rooftop landscape. The incident solar radiation is transmitted to the underlying solar modules virtually unimpeded.
“We would like to use the roofs of the city for clean energy.” explains the Mayor of Graz, Siegfried Nagl. “We are therefore currently looking at possibilities for public buildings to see if we can simultaneously meet the protected building requirements as a UNESCO World Heritage Site.”
A pilot plant installed at the Dennig Manor Farm in Graz-Andritz has been running for several months. Mario Müller, CEO of fibag, the research organization of the SFL technologies, is monitoring the results and notes that “The measurements collected so far surpass all expectations both in commercial and aesthetic aspects.” SFL technologies GmbH has been working for two years on the development of SKIN®energyroof. The glass shingles have a coloured coating that can be adapted to any type of colour.
The idea for the development of the product was formed in a discussion of experts in the Styrian environmental engineering cluster ECO WORLD STYRIA: Together with the ASVK, the Graz Old Town Listed Building Commission, SFL technologies GmbH developed the advanced solution for environmentally friendly energy generation in historic cities, taking into account the technical requirements in conservation areas. This demonstrates once again how Styria reinforces its reputation as the “Green Tech Valley”, as a hotspot for green innovation.
