Name projectWirtschaftshof Linz
Year1999 (Start operation date)
PV applicationFa├žade - integrated in movable sunscreens
PV power total20 kWp
Latitude/Longitude48°18'27"N 14°17'36"E
SummaryThe PV system of this building is very innovative in using a solar tracked lamella system for shading the facade.Solar tracked means: the lammellas are movable around the horizontal axis and follow the sun to be permanently directed with 90? angle towards the sun. The mechanism to move and direct the system is completely solar driven with an thermohydaulic system, developed by ZSW in Stuttgart, Germany. Two thermal collector tubes are installed with the lamellas, oriented to opposite directions. If one side gets more sun the thermal liquid of that tube gets warmer and produces pressure in the hydraulic cylinder, which moves the lamellas until both tubes get equal sunlight. In this position the lamellas are optimally directed towards the sun. The 20 kWp PV modules are integrated on 250 m2 louvres area with 13 different orientations. Thermie project.
