One of Pattern Design's main challenges was to create a structure that could withstand the hot and dry climate of Al Ain. The sinuous and gravity-bending parasol roof is inspired by the Arabic headdress. The roof's design is a departure from traditional European stadium roofs -- which are intended for wetter climates. This one shades spectators, but allows for enough sunlight to hit the pitch. The firm is currently designing Al Rayyan Stadium for the 2022 FIFA World Cup in Qatar.

Architects from NH Architecture observe that the dominant aesthetic of sports facilities are usually composed of steel trusses and generic concourses. The firm opted to create an arena that shifted away from the over industrial scale of stadium architecture. The pleated copper-penny roof is a standout feature.

The London Aquatic Centre is divided into three sections: a training pool, a competition pool and a diving pool. Jim Heverin, project director of the London Aquatics Centre, says the use of the facility was intended to last long beyond the London 2012 Olympics: "Architecture should add to the drama of an event and by doing so, encourage repeat usage and positive association with the facility."

"It's hard to say how much a building can contribute to an athlete's performance, but it was undeniably a unique facility for the London Olympics. It made the athletes relaxed, inspired and able to perform to their best," says project director Jim Heverin. 10 athletes, including Michael Phelps, set new world records at the facility.

The design incorporates energy efficient elements, such as a cooling system that converts rejected heat into a heating agent for pool water. The structure is built primarily using replacement materials such as recycled concrete. Natural light pours throughout the main pool hall.

This new stadium, which opened in 2013, replaced the old San Mames as home to the Athletic Bilbao football club. Principal architect Cesar Azcarate, speaks of the challenges of designing the new structure. "The case of San Mames is very particular and interesting. We had to make a new stadium to replace the legendary San Mames, which was over 100 years old. We had to be able to move all the magic and the atmosphere of the old stadium (known as the "cathedral" of the Spanish league) into a modern one. That was our main challenge, and I think we succeeded."

One of the design's key features is its dynamic facade. It was made using a repetition of twisted ETFE (ethylene tetrafluoroethylene) -- a durable, highly transparent material. Clive Lewis, the senior director of AECOM Global Sport, points to the use of repeating patterns in facade treatment, as one of the trends in sports architecture.
"Stadiums are not only emotive places, but also epic places," opines architect Cesar Azcarate, who designed the new San Mames. "From the stadiums of the Ancient Greece, to the Roman Colosseum, these buildings have an important significance in cities and urban scale, but also in the behavior of people." Azcarate says architects should consider the building's scale, its iconic significance in a city, and the identity of the club to which it belongs, when conceiving its design.

The redevelopment of this facility was an initiative taken on by the IFC Lidingö Football club. The challenge of architects was to create an advanced and well-functioning sports center with limited budget means. Innovative multipurpose design concepts -- such as seating stands that double as a roof over a coffee shop, were employed.

The Steyn City Clubhouse is one of the smaller-scale entries in the World Architecture Festival sport category. The design intends to blur the lines between man-made structures and the natural landscape. Green roofs help the design blend into the surrounding parks, while also help to reduce heat gain.

Some of the materials used in the building are recycled from the land itself. The cladding is made of gabion baskets filled with locally excavated rock.

Located in Zaanstad, in the Netherlands, the center's primary concept is its change in function between the day and night. During the day, the hall is used by schools. In the evenings, the hall is used as a training ground for sports associations. Other facilities include a cafeteria, a conference room and spectator stands.

Materiality is well articulated throughout the building. "The innovative use of materials gives the building a completely new meaning," says Emile van Vugt, founder of UArchitects. "The polycarbonate membrane is a big source of daylight and at the same time it opens the building in a subtle way. The polycarbonate is a modernistic skin that interacts in a new way with the context."

The Lugnet ski jumps in were renovated for the 2015 FIS Alpine World Ski Championships. The jump itself was first built in the 1970s. Sweco Architects modernized the jump to both suit athletic competitions and also function as a tourist attraction during other times of the year. The jump maintains its original silhouette with modern accents -- glass, concrete and galvanized steel.

Editor’s Note: In the run up to this year’s 8th annual World Architecture Festival in Singapore, we preview buildings shortlisted in some of the more unusual categories.

Story highlights

8th World Architecture Festival will be held this November

10 entries have been shortlisted in the sports architecture category

Sports architecture is adapting to hotter climates and more sculptural forms

CNN  — 

This week marks the arrival of the World Architecture Festival 2015 in Singapore, where 338 buildings from 46 counties will compete to be named “world’s best” across 31 competition categories.

Homes, hotels, civic buildings, and commercial developments each play host to a competition category – with some remarkable religious buildings also taking center stage. But, this year, the niche categories are challenging: throwing up increasingly captivating designs for judge’s consideration.

For sports fans, it’s a winning situation. As global competitions such as the FIFA World Cup and the Olympic games continue to attract audiences in the billions, stadiums are changing, and appreciation for the creative design behind them is growing.

“Today, the brutal, purely-functional forms, that rather dominated stadiums in the 80s and 90s, look tired and lacking in vision,” says Clive Lewis, Senior Director of architecture, engineering and design firm AECOM Global Sport. “A subtler form of sports architecture is emerging.”

Lewis is a juror in the sporting category at the World Architecture Festival (WAF), which begins this Wednesday, 4 November. He will consider 10 shortlisted entrants, including sports stadiums, recreational centers, a ski jump and a clubhouse.

Between these 10 completed buildings and the best entrants drawn from other categories, one project will be picked to become the “World Building of the Year,” by a super jury including architects Sou Fujimoto and Peter Cook.

Like competitors in the traditionally celebrated categories – think museums and art galleries, skyscrapers, and five-star hotels – stadiums are now incorporating strong sculptural forms and patterned façades, says Lewis, and responding creatively to new demands, such as extreme weather.

Designing for hot dry climates

The Middle East has seen a boom in stadium construction in recent decades, thanks to the ongoing globalization of sport and lucrative funding of big projects for the purposes of tourism and prestige.

But architects and engineers – for Qatar’s 2022 World Cup stadiums in particular – face enormous pressure to ensure world standard playing conditions.

The geometric shapes on the facade of Hazza Bin Zayed Stadium act as a passive cooling system, rotating to allow fresh air to flow to the pitch.

During the typical World Cup months of June and July, average temperatures in Qatar exceed 50 degrees Celsius (120 degrees Fahrenheit) during the day.

One entrant in the WAF sports category, Hazza Bin Zayed Stadium, uses innovative design tactics to adapt to its arid desert climate. The stadium is located in Al Ain, the second largest city in Abu Dhabi.

Hazza Bin Zayed Stadium's 'parasol' roof provides shade to spectators.

Pattern Design, the London-based architectural practice behind the stadium, took the basic idea of seeking shade in heat as inspiration to invent what it termed a “parasol stadium roof.”

Unlike typical European models where a drip-line roof is installed to respond to wetter climates, the warped parasol roof both shades spectators and allows enough sunlight to shine on the natural pitch.

The outer façade acts as an additional cooling device. Its hexagonal panels, inspired by the bark of palm trees, fan back and forth, allowing fresh air to flow throughout the stadium.

Across the world, new climate demands are inspiring innovation, says Lewis: “We’re now seeing (stadium) designs intended to maximize the amount of shade, moveable ventilation to allow wind to flow to the pitch, as well as advanced technology, such as cooling seats.”

Factoring for human scale

On the other extreme are smaller-scale structures found on the WAF shortlist, which Lewis says can often be more successful than larger scale stadiums.

“Architects struggle with bigger venues. Stadiums become much more about how does an architect integrate engineering,” he explains. “Architects on smaller projects don’t have to worry about this so much.”

“They can make it about the architecture that you go to and experience. There’s an opportunity to create something of high quality, where human scale can be appreciated.”

The Steyn City Clubhouse blends with surrounding green acres.

A departure from usual clubhouse architecture – which traditionally dominates a landscape – Steyn City Clubhouse in Johannesburg, South Africa was specifically designed to blend in with its natural surroundings.

Architects at Boogertman + Partners, one of the smaller firms in the WAF competition, were given the brief to design a sustainable building that would align with the clubhouse’s values – to provide visitors a lifestyle more in tune with nature.

The firm chose to blur the edges of structure and the surrounding parkland, by using a green, grass-filled roof that helps to reduce heat gain.

Emergence of more expressive, sculptural forms

One of the more well-known buildings in the running for the WAF award is the London Aquatics Centre, designed by Zaha Hadid Architects. The concept – informed by the fluid geometry of water in motion – and strongly expressed in its roof’s curvature, compliments the surrounding river landscape of Olympic Park.

The pools, now open to the public, were the site of swimming events during the 2012 London Olympics.

“Architecture should add to the drama of an event,” says Jim Heverin, project director of the London Aquatics Centre. “By doing so, it can encourage repeat usage and positive association with the facility. Architecture can do this in many ways, from large gestures such as the overall design down to the small gestures, like the quality of its finishes.”

2,200 architects from 60 countries will be in attendance at the World Architecture Festival in November. The festival awards designs in 31 differing categories, including sport.
