The design concept divides the total building mass into bands of differing width. The irregularly folded roofs are designed as green roof-gardens open to the public. The Shopping Center offers large-area retail spaces like a supermarket and a home improvement retailer as well as small shops and upscale boutiques, a multiplex cinema, food-courts and various family entertainment facilities.
The new location was greeted enthusiastically by all involved. As a sample of the overwhelming positive feedback we would like to quote Laura Ceccarelli, Supervisor of the Sony Ericsson WTA Tour: “The Porsche-Arena is the most beautiful hall in tennis. I’ve been on the WTA tour for over 20 years and I’ve never seen anything like it. It is not only the best but also one of the most innovative events – and the players see it the same way. Many came up to me and expressed their gratitude, saying: Do you realise how beautiful it is here?”
We are delighted at so much praise!

From 30 Sep to 08 Oct 2006 the renowned Porsche Tennis Grand-Prix tournament was held in the new Porsche Arena for the first time.
The joint-use concept of Porsche Arena and renovated Hanns-Martin-Schleyer Hall turned out to be a huge success: While world class women’s tennis was played in the Porsche Arena the “Sports and Lifestyle Village” in the neighbouring Schleyer Hall offered an entertaining mixture of sport, shopping and lifestyle displays to the visitors.
Galatasaray Sports Club's new soccer stadium will be conveniently located at Seyrantepe a few kilometres north of downtown Istanbul. It will have a capacity of 52.500 seats. The stadium features a retractable roof – the first of its kind in Turkey.
Galatasaray fans all over the world took great interest when the design was presented to the public on Wednesday 09 May.
Cem Arat, one of the principals of 'asp' Architekten, will give a lecture titled “Architecture and Energy Design – Integrated Planning Processes: EWE Arena Oldenburg and other Projects” at the Second Conference on the Future of Solar Architecture to be held on Thursday 21 Feb 2008 in Mainz.
Its hard not to notice it when passing the site while travelling on the “Trans European Motorway” TEM. Seen from above, however, it looks even more impressive: Ever since the end of last year heavy machinery is running on the construction site for the new Football Stadium at Seyrantepe north of downtown Istanbul.
With the bottom slab of the underground car park and several foundation walls already firmly in place the official groundbreaking ceremony for the “Istanbul 212” project (former working title: EDIP Shopping Mall) took place on 19 Jan 2008.
Transformation into football-only stadium will start in May 2009. Work includes lowering of the playing field and subsequent extension of the main and opposite grandstands towards the pitch. The goal-line stands will be demolished and rebuilt closer to the playing field as a two tier structure. A 2,000 spectator sports-hall will be integrated into the stadium structure.

The topography of the sloped site with a level difference of up to 60 meters from one end to the other posed a particular challenge. Special foundation measures were necessary – especially for the large “super-columns” that support the roof structure.
Structural work is progressing and well in schedule according to the general contractor. Sub-contractor for the retractable roof structure will be a Chinese firm that was already involved in the construction of the Beijing Olympic Stadium.
The new arena website is online offering a wealth of information on the project. The construction site is equipped with a webcam that gives visitors an up-to-date view of what is happening on the site.

An additional sports hall for school sports was created with a direct connection to the west side. It is planned that the additional hall will have a dual use as VIP room. With mobile counters and furnishings, the multifunctional room will be used for different events depending on requirements. This possible dual function, without any extra technical effort, also optimises operational costs.
The redeveloped event centre is ideal for the flexible use of a spacious multifunctional exhibition concept. There will be up to 2,600 m² indoor space and 1,100 m² outdoor space (city plat-form), a total of 3,700 m² for events, exhibitions, conferences and congresses.
Considering the area of the photovoltaic rig of 240m² and an expected annual solar irradiation of 981 kWh/(m² a) in Oldenburg, an annual solar energy gain of 21.800 kWh/a was estimated in advance.
Surprisingly just 6 weeks after going into service the system has already produced 50% of its estimated annual energy gain. Ongoing measurements show a continuous energy production of 20% over the initial estimate.
The VIP boxes are arranged on the long side in the north as upper tiers, raised over the premises. There are 90 VIP seats in the stands in front of the boxes. The arrangement of the boxes on the long side with optimum view to the event area guarantees the acceptance and marketing of the VIP area.
Dimensions and track-length of the photovoltaic rig were optimized in order to achieve an economical balance between necessary shading and solar energy gain. The rig is 36m long and 6,7m high. To maximize solar gains the rig moves around the arena covering a 200° angle of the building over the course of the day.
The rig consists of several identical segments mounted on an aluminium substructure making production and operation very cost-effective. Each segment includes a separate drive unit. The rig runs on tracks fastened to the exterior facade rings.
Functionality – building structure
The existing stands are being expanded in a circular manner to create the desired character of an arena. The aesthetic and functionality of the existing stands is maintained. The atmosphere of an enclosed “boiling pot” is upgraded with stands going all the way around.
The facade design of the glazed spectator concourse required special attention in order to prevent overheating during the summer months. The goal was to minimize solar heat-gains without installing an additional solar shading system or mechanical cooling.
A photovoltaic rig that covers a 30° degree angle of the round building and follows the position of the sun over the course of the day turned out to be the most elegant solution.
Development and outdoor areas – “city platform”
The development of the building was conceived from the existing building elements. Access is via a raised plateau in the east of the hall which incorporates the existing entrance. This “city platform”, which expands the inner foyer outwards, is used as a reception and meeting point before, during and after events.
A biaxially arched space-frame structure based on a 6.07m grid spans the 60.40m interior diameter of the hall. A standard metal roof deck supports the membrane roofing. The roof structure can bear additional hanging loads (e.g. stage and lighting equipment) of up to 10 kN per hanging point.
The round reinforced concrete wall compensates all horizontal forces from the roof structure and transfers all vertical loads to the foundations. A light-weight steel roof covers the mechanical services floor. The structure of the lobby is a standard concrete slab on columns.
Urban incorporation
The expansion elements east and westwards were “inserted” as new building components under the existing roof panel and are, therefore, subordinate in the building structure.
The respectful and reserved nature of the building work resulted in a site which harmoniously combines the existing building elements with the new, expansion elements.
The comparatively low ceiling of the lobby is counter balanced by the generous space of the two grand staircases that lead up to the upper level concourse that is completely glazed. From here the spectator enters the actual arena space. The intimate space and the steep seating layout help create an atmosphere of excitement focussed on the game.
The VIP-area is located on a mezzanine level inserted in the concourse. It has a separate entrance and offers direct access to the seats. Service rooms such as locker rooms, press conference room, and storage are located on the ground level below the concourse. Mechanical services are located on an extra level above the concourse.
The sculptural form of the building was inspired by the traditional Islamic “rahle” lectern. Through transformation and abstraction of this traditional image a connection to the regional cultural identity is established without having to resort to the often encountered decorative application of ornamental clichés.
Guiding idea of draft
An overall concept was called for which would suitably realise the various requirements whilst preserving the already existing architectural elements. This was realised by few, structural-sensitive measures in the redevelopment/expansion of the building. An “architectural ensemble” was created which presents itself as a new event centre in harmony with the existing Hohenstaufenhalle.
The regular games of the local major league basketball and handball teams account for a great portion of the arenas occupancy. Additionally concerts, stage-productions and exhibitions are hosted, even classical concert performances were already held here.
The circular shape of the building automatically guides visitors to the main entrance and the lobby.
The library garden in the western part of the building plot, connected to the meditation rooms and children’s library, is planned to stimulate all the senses. An orthogonal network of paths with pergola structures as sun shade is the basis of the design in the garden. The garden has the character of a promenade garden, a baroque pleasure garden or a traditional monastery garden, i.e. it is closed and offers the opportunity to contemplate and communicate while walking.
The changes made to the hall as part of this redevelopment/expansion had to be in keeping with the already existing building to preserve the original architectural character of the hall. Special importance was, hereby, placed on taking great care of the existing building supporting structure.
In plan the single-story cafeteria’s square of 42.8m edge-length merges with a rectangular office building at a 45 degree angle. The ground level contains a vestibule with cloakroom, lunch-counter, dining area, covered walkway towards the parking-lot and a smokers-room.
The office building is 45.9m long and 15.1m wide with three levels above grade and one level below. It holds the associated kitchen as well as office- and conference rooms in the upper levels.
Urban context
EWE Arena Oldenburg is a long-needed addition to the Weser-Ems-Halle exhibition centre. The site is located on the exhibition center's previously neglected southern part in direct vicinity to “Halle 3”, the largest hall of the complex and the smaller “Halle West”. A same-level connection to the existing buildings and a possible joint use of Arena and “Halle West” were requested by the client.
A single-storey lobby connects the new arena with the existing halls. The round building is a highly visible landmark that establishes a link between different directions of the surrounding urban fabric. It creates a recognizable image for the southern face of the exhibition center and is a good visual reference for visitors coming from the main-station.
The base of the building contains public areas such as a conference center, exhibition spaces, the audio-visual library, a bookstore, a children’s library and administrative offices. Above it the grand space of the central library area rises in a sweeping gesture.
Aim of building work
The Hohenstaufenhalle was designed in the 60s by Professor Bernhard Winkler. The hall was inaugurated on 15. December 1967.
