Who The city of Vienna receives energy that is generated from the solar film. In addition, the Naschmarkt is protected from rain and wind by the cover.
Why The rectangular nets are equipped with solar film and connected to each other. Each net is attached to four diagonally embedded pillars. In order to span the large area, nets should be tensioned higher on one side than the other for structural reasons. This ensures that nets remain as stable as possible, even in windy conditions. To connect the Naschmarkt with the restaurants and shops at the opposite of the street, additional nets would be stretched up to those buildings. This not only creates a dynamic effect but also increases the surface area of the solar cells. The ASCA photovoltaic film is applied in aesthetically pleasing pattern on the nets. There is enough space between the films to make the net weatherproof in case of rain, wind, and snow. Furthermore, natural sunlight can still reach the underlying Naschmarkt and the visitors.
How The name “Sopherl” is a pseudonym for all the nameless female stallholders who occupied the majority of the market stalls at the Naschmarkt in the 19th century. The different colors and patterns of the film creates a great pattern by light, and shadows on the Naschmarkt, simultaneously producing renewable energy for the city of Vienna. The net of Sopherl Dach provides enough shade in the height of summer, also offering protection from rain during rainy and windy conditions. However, due to enough gaps between films and its dynamic form, even with covering over the market, the atmosphere appears open and airy.
Where Canopy over the Naschmarkt. As the market is situated in a large area, therefore provides ample space for the solar energy generation. The Naschmarkt is relatively sunny and since the market stands are built rather low in height, they can be covered over easily.
