Arena Pernambuco, Recife
An Integrated Complex Meeting the Multiuse Needs
The  architecture firm Fernandes Arquitectos Associados was chosen to draft  the design for one of the most opulent locations of the Recife region to  host the FIFA 2014 World Cup. Founder and architect Daniel Hopf  Fernandes conceptualized a design that marked a new statement to the  host nation of the Football World cup. He came up with a natural appeal  design, which created a curiosity among the people of Recife region.
 
The  Arena Pernambuco, which is part of a complex which also featuring  restaurants, shopping centres and cinemas, is located in Sao Lourenco da  Mata in Recife’s metropolitan zone, just 19km away from Guararapes  International Airport. The project is seen as an economic catalyst for  the continued expansion of Grande Recife, within an area which is  considered to be economically deprived. It is also estimated that the  area will expand into a neighbourhood including nearly 5,000 homes.
In  an exclusive interview with Built Expressions, Fernandes Arquitectos  Associados shares more on this overwhelming project of Brazil.
Arena  Pernambuco - a private stadium with unique and modern design is built  in a great natural appeal area. The audience will be entertained with  bars and retail outlets strategically installed in all sectors, which  will lead to attracting new fans and increasingly bring families to the  field, enabling new experiences and extending leisure options before and  after matches.
 
Arena  Pernambuco is designed to be a "multipurpose" Arena, since it has  capacity to host events of various kinds, such as concerts, festivals,  conferences, and trade shows, as well as sporting events. So the space  will be a great and attractive urban centre with residential,  commercial, educational, and entertainment areas, which will be of great  importance for the economic growth and expansion of the metropolitan  area of Recife.
Natural Appeal
Fermandes Arquitetos
“As  formal conceptualization for the design, the intention was to take  advantage of the arena location in an area of great natural appeal and  generous dimensions, creating a single project and fully integrated into  its surroundings with the smallest possible visual impact, however, of  great visual appeal. A simple and impacting, easy-to-read shape that  raises curiosity, which is inviting and attractive. We sought a way able  to bring the feeling that the building sprang of the terrain, rather  than having been placed, built. Instead of the usual solution of the  high construction with striking vertical projection and generous  volumes, characteristic of large-capacity arenas as the one planed, the  design reverses the sense and eases its boundaries through slanted and  smooth transition, which extends out blending the building with the  landscape, transforming Arena Pernambuco in part of the local  topography”, says Ar. Daniel Hopf Fernandes.
 
Arena  Pernambuco is a multipurpose space that integrates the new development  centre in Recife region into a project that cherishes for sustainability  and preserves the natural characteristics of the surroundings. The  Arena design fully meets the multiuse needs and may host different  events, such as concerts, festivals, conferences and fairs, in addition  to sporting events. All infrastructure planned for the Arena will be  capable of meeting different demands that these events requiring,  counting, for instance, with a broad conference room, auditorium for 420  people and press room.
Cladding and Coverage
One  of the primary highlights of the stadium is the cover, which as added  more beauty to the stadium. “ A great cover was designed in order to  provide greater comfort to spectators and better condition for the  broadcast, press areas and VIP sectors. The support structure consists  of steel space frame anchored in metal pillars. Its upper cladding  consists of two distinct sections: the outer ring is closed with thermo  acoustic tiles, providing shade and protection from the rain, while the  inner ring consisting of glass cladding, in order to avoid large shade  areas on the lawn, which can harm both the health of the grass and the  games broadcasting on television. The lower part of the structure will  be partially closed with perforated metal tiles, providing greater  lightness to the set” , explains Ar. Daniel.
 
Technical  walkways enables easy access for eventual maintenance in the coverage  or any equipment that is fixed on it, such as screens, speakers, field  lighting reflectors and light fixtures to the bleachers.
 
Its  coverage, with area of 19,600.00m², consists of steel space frame in  balance anchored in metal pillars, with upper cladding formed by an  opaque outer ring and transparent inner ring. In total, the coverage is  fixed to 68 metal pillars, which are directly supported on the concrete  structure. The opaque section is a system consisting of a thermoplastic  membrane of flexible Polyolefin (TPO), thermo-insulating boards of rigid  polyisocyanurate foam coated with a fibre glass layer on both sides and  galvanized steel tiles.
 
The  transparent section, in turn, is a system formed by laminated glass  frames, pre-manufactured and encapsulated with structural silicon. The  proportion between the opaque and transparent sections was done in such a  way to allow maximum protection from the stands without creating  shadows on the lawn that could harm both broadcasting of events and the  natural growth and maintenance of the grass. At the bottom of the  spatial structure, a cladding with pre-painted perforated metal tiles  provides greater lightness to the set.
 
The  spatial structure consists of steel bars fixed to massive steel spheres  that allow the bars to be fixed at any point along its surface,  providing great flexibility in the adaptation of the geometry of the  arena coverage. Technical walkways located within the spatial structure  along the entire perimeter of the cover allow access to video screens,  sound equipment and lighting fixtures of the stands, besides the field  lighting reflectors installed on the section with glass cover.
Bonding with People 
“With  a capacity of 46 thousand supporters, Arena Pernambuco is a  multi-purpose arena and is located in a strategic point in the  metropolitan region of Recife (PE), which in the future will be home to a  complex of great importance for the local socioeconomic development: a  new urban centre with residential, commercial, educational, and  entertainment areas that will have fundamental importance on the  expansion and development of Greater Recife,” shares Ar. Daniel
 
The  area chosen for implementation of the new Arena Pernambuco played a key  role in the architectural design concept, creating new possibilities  and allowing differentiated solutions to a modern, efficient arena model  and integrated to its surroundings and with the natural and  sustainability aspects.
 
Located  in São Lourenço da Mata, metropolitan region of Recife, in BR-408  highway, the area borders Capibaribe River, with the highway and with  large environmental protection areas, where part of the remaining native  forest can still be found. A large natural semi-preserved area between  preservation areas and with strategic location is the setting for the  design of the new Arena Pernambuco. Due to the large size of the area  chosen, the design of the new arena is located within a larger  occupation plan, The World Cup City. It will be a new urban centre that  will feature residential, commercial, educational, and entertainment  areas, which will contribute to the development and expansion of the  metropolitan area of Recife.
Challenges
Since  its a massive stadium to be raised, the people involved in the process  of construction faced numerous challenges. When queried on this Ar.  Daniel said, “The main challenge of this project was to reconcile a  construction of great impact in an area of environmental protection,  where one can still find part of remnant bush land. The area chosen for  implementation of the new Arena Pernambuco played a key role in the  architectural design concept, creating new possibilities and allowing  differentiated solutions to a modern, efficient arena model and  integrated to its surroundings and with the natural and sustainability  aspects such as: Storm water reuse system; Water heating system through  solar collectors installed on the roofing; use of equipment and devices  to save water in all toilets and change rooms; use of photovoltaic  panels for power generation through solar energy and use of natural  lighting and ventilation”.
Safety Aspects of the Stadium
The  concern with public safety was paramount in the design of Arena  Pernambuco.All circulation spaces, accesses, runners, vomitories and  other structures are scaled according to international standards,  allowing for correct and comfortable public shift in normal and also  emergency situations. The stadium is incorporated with control room with  view of the lawn and bleachers; Safety room; Closed circuit television  (CCTV), for surveillance and monitoring of the common areas; Access  control system to integrate the system of access to events and access to  restricted environments of the building, consisting of central station,  electronic turnstiles, e-cards, electromagnetic lock, among others;  Digital fire detection and alarm system; Audio system to allow  communication with the public in internal and circulation areas of the  stadium; Sets of ramps and pressurized stairs protected against fire.
Features
As  functional concept for the design, in addition to the safety of  spectators, the main objective is to create the ultimate in comfort for  users and differentiated ambience in all areas of the arena, creating a  unique experience for fans and players. The stands were designed using  modern concepts of visibility, comfort and safety. Its format and  vertical stratification provide proximity and excellent field vision for  all, creating the ambience needed for the public and players. The  audience of bleachers is formed basically by the general public and the  VIP public. For the general public, large areas of circulation with bars  and toilets were provided to accommodate all supporters with comfort  and safety. For the VIP sectors, large living areas with special food  services and exclusive bars bring a greater comfort to the public.
 
Another  particularity of the Arena Pernambuco design is the use of ETFE  (Ethylene Tetra-fluoroethylene), material used for the first time in  Latin America. The side cladding of the of the Arena Pernambuco facades  comprises a pneumatic pillows system in ETFE films, which edges are  attached to a metal structure by means of aluminium profiles.
 
The  combination between transparent and opaque films, as well as the  application of several types of screen printing on the surface thereof,  confers a constant dialogue between the indoor and outdoor areas, as  well as allow a diverse lighting control inside the arena, according to  the different uses under the membrane, such as to mitigate the effects  of heat gain by the side cladding surface. Another sustainable detail is  that the membranes made with this polymer are 100% recyclable, with low  friction rate and non stick properties, preventing dirt and dust  particles to be deposited on its surface.
 
The  film used by Vector Foiltec in the manufacture of pneumatic pads of  Arena Pernambuco is a high performance fluoropolymer film developed and  manufactured by AGC Chemicals, in its unit in the city of Chiba, Japan.  It is an ultraviolet light-resistant material and suitable for long-term  use outdoors.
 
Also,  the facades have openings that allow the use of natural ventilation and  help in the control of internal temperature, contributing to the  comfort of users.
 
In  terms of design the stadium is an absolute mark of pride and honour to  the Recife region of Brazil. The architect as solely put his effort to  sculpt an excellent design of the stadium. Thus, Arena Pernambuco is a  brand new structure of attraction to the people of Brazil
