Project summary
EWE Arena Oldenburg is a sports- and multipurpose hall which is located at the edge of the fair ground of Oldenburg. The exterior walls are totally glazed. To prevent the building from overheating in summer the exterior walls are shaded by concrete overhangs as well as by a large movable PV-Shading system which circulates 200° around the building exterior according to the position of the sun. The 6,5m high and 36m long PV-Sunscreen covers a 60° segment of the circular building. The tracking is done every half hour in 7, 5° steps. The building did win several architecture prices. It also becam one of the five winners of the 2006 Federal Photovoltaic Award “Photovoltaik im Gebäudeentwurf” awarded by the Federal Ministry for the Environment and the German Association of Architects.

Special PV project info
PV architecture and building integrationThe PV-suncreen consist out of 72 PV-Modules and 72 glass elements with screen printing. The total weight of the movable sunscreen is 28t. It rests on steel rails the bottom and the top, which are fixed at the concrete structure. The sunscreen is hanged up on the upper steal rails whereas the lower steel rails functions as the guide way and takes care for the wind loads. The sunscreen consists out of 18 segments, which hold 8 PV-modules each. The frameless PV-Modules are designed to be semitransparent and are built up out of crystalline cells. The three inverters are mounted directly on the movable sunscreen. The cabling is done with the help of a distributing jumper ring at the top.
