The new Bremen Weser-Stadion: A Home Match for the Future The Real Football Feeling. It took almost three years to reconstruct the Bremen Weser-Stadion into a pure football arena. Fans are now getting an absolutely first-hand football experience. The whole spectator area including the curved fan stands has been moved close to the pitch, allowing for an even better view of play. However, in the new Bremen Weser-Stadion, the winner is not only football, but also the environment. Following the slogan “A Home Match for the Future”, a novel energy concept was realised. The core of this energy...

Reconstruction of the Bremen Weser-Stadion within two halves and an extra time GmbH in Westerstede partnered in the “Consortium PV Roof Weser-Stadion”. With a view to coordinating and executing all electrotechnical works, the Consortium also contracted an electrical installation company. Alternating between playing and building the project, which was divided into several construction phases, began in 2008 with the dismantling and subsequent rebuilding of the northern and southern stands (1st construction phase). Naturally, 3th construction phase: Rebuilding the western curved stand 4th...

The new roof of the Bremen Weser-Stadion with EVALON® Solar. Completely new roofs As a first step, on all new-built roof areas an even and load-distributing substrate had to be achieved for the further roof build-up. To this end, steel workers installed plain sheet metal on the trapezoidal sheet profiles and fixed them with screws through the corrugation ridges. Subsequently, roofers applied 30 mm thick refurbishment insulation boards. These highly compressed, extremely hard and thin roof insulation boards consisting of incombustible mineral wool, on ▴ Dismantling the old roof build-up the...

Flat roof and solar technology: If there’s one thing we know, it‘s both. Multi-purpose waterproofing membrane A special advantage of the multi-purpose roof waterproofing is the convincing combination of the proven EVALON® waterproofing membranes and flexible PV modules. Like any standard waterproofing membrane, EVALON® Solar is installed on the roof directly from the roll. The flexible and light-weight UNI-Solar® PV modules are all-side weatherproof in a transparent polymer encapsulation and full-size laminated to the synthetic waterproofing membranes. The patented connection system allows...

A Home Match for the Future: A win-win situation for both football and the environment. About 10,470 m² of the stadium roof area of approximately 18,000 m² are covered with the world‘s first powergenerating waterproofing membrane EVALON® Solar. This amounts to a total power yield of around 511 kWp, i. e. 156 kWp from the curved stands each, 103 kWp from the southern stand and 96 kWp from the northern stand. Together with the other PV systems installed at the stadium, the total installation area amounts to almost the size of two football pitches annually generating up to 1.2 MW of electric...
