The Semper Opera in Dresden
One of the most beautiful theaters in the world rises radiantly above Theaterplatz on the Elbe River and forms the center of the historic Old Town.
The Semper Opera House is incomparable in Europe: it has a unique architecture, because the functional parts of the building are already visible from the outside. A first glance reveals the foyer, the staircases, the auditorium and the 40-meter-high stage tower. This construction method represented a novelty in theater building.
The State Company Saxon Real Estate and Construction Management (SIB), as the owner of the Semper Opera House, is responsible for all planning and construction projects at this building on behalf of the Saxon State Ministry of Finance. In the context of the energy refurbishment of the stage tower, the SIB commissioned GWT together with Prof. Grunewald from the Institute for Building Climatics at the TU Dresden to compare construction variants for the stage tower roof.
On all roofs of the opera house, the roof structure is from the 1980s with a correspondingly low level of thermal insulation and fire protection. In consultation with the authorities responsible for the preservation of historical monuments, two variants were developed which, with a slight enlargement of the roof structure, result in a significant reduction in energy consumption.
