international practice Aedas is nearing completion of the ‘al-bahr towers’ for the abu dhabi investment council headquarters in abu dhabi, that utilize what is perhaps the largest and most advanced interactive sun-shading skin system. the two 25-storey office towers are parametrically designed based on islamic geometric mosaics, using the tessellation of simple shapes to drive the structure. the cylindrical forms maximize volume and floor-to-wall area while offering views in all directions, unfortunately however, this also opens the interior to a very large solar gain factor which is a substantial problem in the extreme local climates.

reinterpreting the traditional wood-lattice screens called ‘mashrabiya’ using today’s technological abilities resulted in an outer skinsystem of triangular screens arranged in a series of scalable hexagons fold up to create a solid solar barrier. each of the 1000 panels is connected to a linear actuator which enables it to function in response to the position of the sun, effectively reducing heat gain and glare by 50% while giving islamic vernacular a contemporary representation. the intelligent facade, together with solar thermal panels for hot-water heating and photovoltaic panels on the roof, minimize the need for internal lighting and cooling, altogether reducing total carbon dioxide emissions by over 1750 tons per year.

  • Look like busted condoms from a distance. One week’s worth of visual tech interest. Get the $$ while you can.

  • excellence through innovation

    Jim, you have a filthy mind

  • The umbrella fold is a good idea, next iteration should be better.
    Only half-evolved I reckon.
    The rest of the building too gimmicky for no reason (not a-maize-ing)

    mackenzie collins says:
  • I think buying a thick curtain is much better 🙂

    T. dorothy says:
  • A scultural, ‘active’ way to control solar gain. Why not create an external skin which impedes solar gain, admits light and generates solar electricity? The lifecycle ROI alone would put a smile on more than the building user’s dial!

    Sustit says:
  • nice one 🙂 creative shading system 🙂

    Salah says:
  • Good idea and pratice,bring me another greater! thank you!
