Sopherl Dach

Sopherl Dach by Jana Kaufmann

Cov­er­ing large urban areas while simul­ta­ne­ous­ly gen­er­at­ing renew­able ener­gy using solar film.

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.
