The noise barrier project consists of 4 pieces located in the city of Hong Kong along the streets of Tai Po Tai Wo Road e Gascoigne road.

Hong Kong Noise barrier

  • Architects: Francesco Lipari
  • Project: Hong Kong Noise barrier
  • Location: Hong Kong
  • Organizer: Government of the Hong Kong Special Administrative Region
  • Cost: € 2 M
  • Materials: lenght 500m, height 6m, Steel 900t, 9000 polycarbonate panels
  • Project Team: Vanessa Todaro, Pierpaolo Pugliano
  • Timing: design 2009

Hong Kong Noise barrier

A cantilevered barrier of 170 metres long and 6 metres height, a vertical barrier of 140 metres long and a variable wide from 23 to 20 metres, a vertical barrier 70 metres long and 4,5 metres height and a semi-full-cantilivered noise barrier of 500 metres long and 6 metres height.  The space frame structure of the noise barrier has been constructed from hot-dip galvanized 50 mm tubes for the main structure and 30 mm tubes for the secondary structure. The entire structure is covered with translucent polycarbonate panels, with a different range of apertures, each one with a dimensions of 3 m x 0.65m. The panels change color with the daylight and react to the impulse of the shaft located at the intersection of every panel. During the day, the new noise barriers forms an harmonious unity with the surrounding landscape. They also integrate an innovative green system. The design is developed incorporating the natural growth characteristics of the grass. What makes the design unique is that the construction itself, as a sound barrier is a living, green unit. Light and shadow on the white panels establish a suggestive relationship with the surrounding landscape. After sunset, the artificial light illuminates the architectural body from inside, turning the shapes into a illuminated sculptures.

HIGH TECH BLADE RICCIO ©

The focal point of the whole system is the blade named RICCIO ©

It’s an innovative technological system that transform the air movement in energy and then, thanks to a generator, in electricity. The blade dimensions are: a = 1 cm; b = 1 cm; l = 40 cm; Weight = 150gr

Skin

During the vehicle transit close by the noise barrier it produces a pressure wave with a kinetic energy and potential. This energy is transferred to the blade orthogonally to the wave front. Then the blade stimulated by the wave, begin swinging in analogy to a damped harmonic oscillator.

Panel detail with RICCIO system

Considering the kinetic energy E = ½ *m*ω2A2 = ½*m*K/m*A2 = ½ *(a*b3)/(4h3)*α*A2, the blade dimensions (a, b, l), the material (α) and the extent of the first oscillation, the energy produced by the blade (per second) is: E ≈ 1 Joule   or   W ≈ 1 Watt.

Concept air movement

The electricity produced will be stored by appropriate capacitors. The electricity will be used to manage the noise barriers and to provide clean energy for the districts.
