BIG: shenzhen international energy mansion

BIG, in collaboration with arup and transsolar, was awarded first-prize in an international competition to design shenzhen international energy mansion, the regional headquarters for the shenzhen energy company.

the purpose of the international design competition was to find a sustainable and efficient solution for the shenzhen energy company office headquarters. located in the centre of shenzhen, the 96,000 square meter project will be integrated with the surrounding environment and designed to withstand the tropical climate of the city.   the headquarters which rise 200 meters above ground will be a landmark for the city.  the façade was conceived as a folded skin that shades the office complex from direct sunlight and integrates solar thermal panels, reducing the overall energy consumption of the building.   shenzhen international energy mansion – view from highway

‘we propose to make the shenzhen energy mansion the first specimen of a new species of office buildings that exploits the buildings interface with the external elements – sun, daylight, humidity, wind – as a source to create maximum comfort and quality inside. the shenzhen energy mansion will appear as a subtle mutation of the classic skyscraper – a natural evolution rather than a desperate revolution.’ bjarke ingels, founding partner, BIG.   shenzhen international energy mansion

the traditional glass façade has little insulation leaving the offices overheated by direct sunlight. this results in excessive energy consumption for air conditioning and the need for a heavy glass coating that makes the view seem permanently dull and grey.   by folding the façade in an origami like shape they achieved a structure with closed and open parts. the closed parts provide a highly-insulated façade, while blocking the direct sunlight. on the outside the closed parts are fitted with solar thermal heat panels that power the air conditioning and provide dehumidification for the working spaces.

the folded wall provides a free view through clear glass in one direction creating a condition with plenty of diffused daylight by reflecting the direct sunlight between the interior panels. even with direct sun from east or west, the majority of the solar rays reflect off the glass, due to the flat angle of the window. the reflected rays increase the efficiency of solar thermal energy panels. the combination of minimal passive solar heating and active solar panels reduce the energy consumption by more than 60%.

  • BIG have estimated that the use of solar-powered air conditioning and reduced heat from direct sunlight could reduce the energy consumption of the building by more than 60%. That’s really great!

  • rainwater is collected ?

    Marie says:
  • Passive solar design and natural ventilation concepts work better in more northerly climates, but it seems that the façade fits with the ventilation, and the shape of the building fits with the local solar access.

    Doug R. says:
  • Architectural sustainability down-to-earth!

    Susanne says:
  • ORIGAMI IS IN

    Bill Palmer says:
  • Come on! is this really the best solution chosen form a field of competing architects? What a shame, and an easy win for BIG.

    Nicola, Athens, Greece. says:
  • Im afraid this would be just another source of light pollution

  • More fashions welcome go to visit [url=http://www.tradebeneficiary.com/] http://www.tradebeneficiary.com[/url%5D

    DFDS says:
  • I sure hope the sustainability makes up for the lack of architectural ambitions. Why even mention revolution. Is this really a sublte mutation, or did the team not have enough time to develop a proper proposal? So sad.
