BARBARA LEONARDI AND OLIVER DIBROVA

Hybrid Hotel

source: exame

Dubai é internacionalmente conhecida como um destino de luxo, permeada por hotéis de altíssimo padrão e arquitetura surpreendente. E um projeto, ainda em fase conceitual, a enfeitar a já dinâmica paisagem local tem uma inspiração muito pertinente, o fenômeno das dunas que cantam. Tal processo ocorre quando grãos de areia colidem uns nos outros enquanto as dunas se movimentam, turbinadas pelos ventos do deserto, fazendo com que sons sejam emitidos e ouvidos a uma distância de 10km.

Os arquitetos Oliver Dibrova e Barbara Leonardi, do Hani Rashid Studio, se basearam em estudos sobre o processo natural, cujo som lembra o rufar de tambores, e que “traduziram” a frequência e amplitude para o papel. O resultado foi este prédio com diferentes superfícies espiraladas e que une quatro hotéis diferentes e independentes.

Dubai, the Arabian Peninsula’s most vibrant city, boasts over 30% of the world’s cranes at work and is the planet’s fastest growing urban settlement. It is a place of extremes, from its climate and physical context, to its economic and geopolitical strategies to its urban infrastructure and architecture. Here, limits are constantly being tested and surpassed, producing a city that today is subject to a Darwinian trajectory. Dubai is either quickly becoming one of the most extraordinary and evolved cities, or a travesty of extravagance and excess, the potential result of both misguided vision and ambitious, yet flawed enterprise. Recent developments provided the context for the studio to design a resort hotel complex in Dubai. The studio explored the extreme condition as it is manifest in Dubai today and in its future trajectory.We were interested in the phenomenon of singing dunes in which sounds are produced when grains drum against one another, exciting elastic waves on the dune surface, with the vibration of the sand bed tending to synchronize the collisions. Inspired by that we created a system by these principles to create surfaces influenced by soundfiles which represented different kinds of program conditions. The result of this experiment were diverse surfaces, which can be used to generate a hybrid space. At the highest peaks the surface starts to split and rises in the height . We chose this area for our hybrid hotel a spiraled structure that continues the public space and contains four plugged in hotel-units, which can act independent from each other and are specialised on diverse topics (business hotel, recreation hotel, sports hotel and city hotel).

Singing dunes – in order to study the sounds of desert sand dunes, Bruno Andreotti first had to trigger avalanches by sliding down the dune face. “Singing dunes are one of the most puzzling and impressive natural phenomena I have ever encountered,” says Andreotti. “The sounds can be heard up to 10 km away and resemble the beating of a drum or the noise of a low-flying jet.” The dunes produce sounds that are as loud as 105 dB – roughly equivalent to a car horn – and have frequencies between about 95-105 Hz. “The sounds are produced when grains drum against one another, exciting elastic waves on the dune surface of the sand bed acts like the membrane in a loudspeaker.”

Cantando las dunas es un fenómeno que se encuentra exclusivamente en los ambientes desérticos. “Los sonidos se producen cuando los granos chocan uno contra el otro; emocionantes ondas elásticas en la superficie de la duna de la cama de arena actúa como la membrana de un altavoz.” Los sonidos se asemejan a los golpes de un tambor o el ruido de un avión en vuelo bajo. Que se puede escuchar hasta 10 km de distancia.
El rascacielos fue diseñado por Barbara Leonardi y Dibrova Oliver como parte de Hani Rashid Studio. La principal inspiración fue encontrada en un fenómeno de las dunas de canto. Hipotéticamente situado en Dubai, el proyecto es un espacio híbrido, con superficies de diversos representantes de diferentes condiciones programáticas. Una estructura en espiral continúa el espacio público y contiene cuatro unidades de hotel insertadas, que pueden actuar independientemente unas de otras y están especializados en diversos temas (hotel de negocios, hotel y centro, hotel deportivo y un hotel de la ciudad).
La configuración final del edificio se encuentra a través de un experimento: un plato o tambor se ve obligado a vibrar históricamente con un arco de violín o con un altavoz. Una arena fina o polvo se esparce sobre la superficie y se deja asentar. En él se establecen aquellas partes sin vibraciones de la superficie, es decir, los nodos de vibración. Mediante una ecuación de los ceros de onda estacionaria en la placa cuadrada, diferentes archivos de sonido-se extraen y se utilizan como materia prima. Están traducidos a la frecuencia y amplitud, eventualmente generando una estructura 3D.
