Transcript of STADIUM FACADES
55, 000 Capacity
$150 million to build
Completed July 2009 KEY INFORMATION main structure of stadium uses recycle and 100% recyclable materials
all made in Taiwan to lessen the cost of transportation and carbon emission
The structure of roof adopts lightweight design and installs spiral steel girders and 8,844 solar panels.
the lightweight roof functions as earthquake-resistant structure, and also generate electricity which reduces 660 tons of annual carbon dioxide output
largest solar-powered stadium in the world with it’s 14,155m2 roof
enough to power up to 80% of the surrounding neighborhood FACADE INFORMATION
Facade Section Nou Mestalla Facade Structure Construction on the 90,000m2 site started on March 2007.
Was Due to be completed in 2009, but due to financial difficulty its opening has been put back until 2010/11.
Project Value: 200M Euros.
Stadium is meant to be iconic for the entire city and the aim behind it's construction is ’To build the greatest stadium in the world’.
Stadium: Three-tier design. Based on a bullring.
Stadium can be transformed into an athletics 50,000 capacity athletics stadium.
Site was small/restricted, so the upper tier incorporates structural roof elements to save space. The pitch is below street level to reduce the height.
The non-structural façade was inspired by the cities map. It is aimed to provide an envelope to the stadium that is an iconic representation of Valencia and Valencia FC.
Encompasses high innovative construction that will set the benchmark for future stadiums. More than just a football stadium.
There were several different design and construction teams involved with the project.
The curvaceous design resembles a virtual map of Valencia.
The design is based upon the city 16 districts. Each district is represented on the aluminium design.
The Bowl design blends an aluminium and glass exterior with a wooden interior.
The Interior is aimed to establish atmosphere, whilst the facade is aimed to provide character.
Façade is formed of 16 large perforated aluminium segments, which consist of an overall quantity of 23,000 aluminium 2.1x1.2m scales.
The Turia River that runs through the city is represented by glass skylight. It links the districts.
The aluminium shells appear to float on each other; giving a weightless feel.
Façade acts as ventilation. Computer-controlled louvres ventilate the spectators and pitch depending on the climatic conditions.
Solar Panels are on the roof to provide environmentally friendly energy.
The innovative geometric design that represents the city is aimed to show the universal support behind making Valencia FC an elite club.
Project Information Facade Design Facade Construction Located in Cape Town, where the old Green Point stadium used to stand
Built for the FIFA World Cup 2010
Total Development Cost: 4.5 billion Rand (£394 Million)
It has one Primary façade system, which is a linearly arranged cable-suspended, translucent ETFE membrane.
Façade consists of a lightweight steel and aluminium frame which hangs off stadiums main concrete structure.
The ETFE membrane forms a continuous taut but flexible skin which is clipped onto the secondary structure.
The ETFE is a cloth membrane, which is partly permeable.
Has a “breathing” softer inner skin and disperses sound waves.
Limited recycling opportunities for membrane as it is a plastic like material which does not decompose.
Designed to last up to 30 years.
Multi-functional use Sustainable integration Innovative construction methods Bespoke Facades Modern materials Stadia Development China 2009 World Games Stadium Nou Mestalla - Valencia Fc Green Point Stadium - Cape Town Dallas Cowboys - USA External Aesthetics of stadiums have changed significantly over the last 20 years. The construction of a new stadium has become almost an art form, where the facade has often become a cultural iconic representation of the city where it stands. This has been made possible through the advancement of construction technologies and materials Case studies illustrate how important the integration, role and technogical advances of the facade, are to the overall impact of the stadium. Some of the generic characteristics that we have found, are included in the following; Lightweight structural memebers
Hollow members providing greater flexibility in design, with an increased strength
Increased engineering technology with the integration of advanced materials such as EFTE
Making use of the materials due to their specific capabiliteis in relation to the acoustic, aesthetic, sustainable and environmental qualities.
"Steel Arches" Two boxed shaped steel frame arches each spanning 1,225 feet in length, 292 feet above the playing field. (35 by 17 feet wide, weighing 3,255 tons each). "Retractable Roof" Retractable roof is supported by two steel framed arches (each roof panel opens and closes in just 12 minutes). "Infolding External Wall" Infolding exterior wall with a 86-foot high glass curtain-wall surface serves as the main entrance.
The retractable end-zone doors glide on a track fixed to the ground and rollers at the top. Each sliding door is powered by two small 3 hp motors.
"Roof Cladding" The non-operable portion of the roof is constructed of Sarnafil’s vinyl Energy PVC panels chemically welded together and connected to the roof deck with a series of screws and plates.
The retractable portion uses Teflon coated fibreglass fabric.
"Façade" The façade is constructed of light weight steel frame members fixed to concrete columns and beams. The frame is used to support the large sections of glass panels.
Dallas Cowboys Stadium Project Information Its unique undulating silhouette, which is the result of the geometry of the stadium body, transforms the stadium into a sculptural object.
It will resemble a rose-coloured bowl floating on a base when lit up at night.
Dubbed “the diva of Cape Town”, due to its ability to reflect the constantly changing moods of the city in varying weather conditions.
At sunset, the stadium possesses a reddish glow, a blue one on a bright summer day and has a grey appearance during stormy days in winter.
Prominent Features Facade Design Façade is attached to main structure, a series of 73 concrete pillars, braced with steel cross bracing. Uprights are to support upper tiers.
Formed with climbing formwork with steel reinforcement for tensile strength.
Steel hinge plates are bolted directly to primary concrete structure.
Workers are harnessed for height safety.
The columns tie together with cross bracing steel components.
Steel structure is fixed from elevated platforms and light cranes to hoist materials.
Hollow steel sections are hung off in a trussed space-frame formation.
The horizontal components are attached to form a mesh-like lightweight steel structure.
The ETFE membrane is clipped to this secondary structure, hung taught from the top of the structure to the bottom.
2 Point Connections to Reinforced concrete Main Structure
Steel Tubular sections on both sides of the Twisted girders creates a net like surface to which to attach the Solar panels.
Both Solar Panels and Laminated Glass section are used.
Laminated Glass sections allow light to penetrate through the structures facade roof
Building adjusts the natural site to induct natural wind which modulates the temperature.
C shape of Stadium uses natural light and offers shading effectively.
Interior space air circulation has been taken into consideration to decrease the load of air conditioner.
To lessen the energy wasting, the roof and hull of Worlds Game Stadium use special techniques and materials to meet the effect of insulation.
Materials Recyclable Steel
Reinforced conctrete from 100% recycled materials
All Materials Resourced Locally in Taiwan reducing transportation costs and reducing pollution
Local Impact Local Area benefits from Electricty provide by the stadium
Nature areas created for general public
Represents the cultural beliefs of the local area in design and function
