With the new headquarter for the publishing house Spiegel WICONA demonstrates in an impressive way what the new slogan „technology for ideas“ means in practice: a whole range of special bespoke solutions were developed for double skin facades, windows, SG curtain walls and unitised systems, so that this architectural design can become reality.
For the new seat of the news magazine Spiegel in Hamburg the WICONA project department had to come up with a series of bespoke solutions to be able to fulfil all technical, visual and ecological requirements, like e. g. a U-value below 1.0 W/(m2K). This project called “Ericusspitze” can be considered as a true proof of the company’s performance and innovative strength in the implementation of such a large scale landmark project.
Designed by Danish architect Henning Larsen, the 2 buildings with an investment volume of 180 Mio. € provide mere 50.000 m2 of office space and can be considered as a new landmark between the city centre and the harbour of Hamburg.
A wide range of specific system constructions and profiles had to be designed in order to meet all requirements. The buildings receive a combination of double skin facade with wood compound windows and triple glazing, a stick system curtain wall in structural glazing technology, and a number of aluminium windows.
The energy and services technology concept of the building integrates aspects like ecology, economy and social integrity. Thus sustainability is the key word for the integrative planning of the project. After completion the building strives for the supreme environmental award in gold of the Hamburg city.
All curtain walls are optimised in their energetic design and achieve a U-.value of below 1.0 W/(m²K). As a result the façade units with a width of 1,35 m comprise a transparent fixed glazing of 95 cm and an opaque sash of 40 cm, resulting over all in a transparent surface of 50% of the building. The entire aluminium frame constructions will be pre-fabricated in units by the metal building company Schindler GmbH and then installed on site. This production process guarantees short production and assembly times as well as highest manufacturing quality in the company workshop.
The entire building is planned to be finished by the end of 2010.
