with the population of new york city constantly on the rise, paolo venturella believes that its citizens expect an advanced classification of architecture to arise in retaliation. even if carbon emissions have to be reduced, the use of energy still increases. on his journey to find a solution, the italian architect has developed ‘flex tower.’ the typology proposes the utilization of photovoltaic panels in a controlled manner to prevent a mass dispersement of the system throughout the metropolis. thus, each one must be tilted and rotated specifically in relation to the sun and relative to where it resides along the façade of the building.

at the ground level, the design respects the manhattan’s grid, while the higher levels rotate towards the sun, allowing the panels to displace accordingly. the overall rotation and flex of the skyscraper results in an appropriate 30-degree angle facing the sun. simultaneously, the diagrid decorating the exterior surfaces works as a structural and performative skin of stainless steel. this envelope uses an organization of different modules that change the density of the photovoltaic cells and creates open floor plans free of any supporting elements.

  • yeah, but what about the shadow this tower casts ?? it’s always about the shadow…

    aa says:
  • Very efficient? Now how about access to top floor? Where are the lift cores? How about overshadowing? How about you now cannot build high next to it or under it as it blocks all natural light? When land price is at a premium this design is anything BUT efficient… Just even a simple thought of how do people scale a curved building like this to change panels when they break?

    bob says:
  • Hilarious! Love joke “architecture”.

    mArkW says:
  • It would ruin retail in the area.. nobody would walk anywhere near it. Maybe better for Texas where nobody walks anyway.


    jimCan says:
  • what they said 🙂

    Rich says:
  • Go home building, you’re drunk!

    lisa says:
  • BIG want their methodology back.

    Jeremy says:
  • not sure about this, but for me the logic is all wrong in this building, i am not talking about the structural efficiency nor the technical aspect such as lift cores, etc. But if the aim is to create energy efficient building, why they oriented it unto the sun? even flex it further that could increase glare/ unwanted sun light?

    we need to see more diagram explaining this.
