Energy Roof Perugia by Coop Himmelb(l)au


Austrian architects Coop Himmelb(l)au have designed an energy-generating canopy for a passageway in Perugia, Italy.

Called Energy Roof, the structure will consist of three layers: photovoltaic cells at the top, structure and wind turbines in the middle, and a glazed underside.

Here's some more information from Coop Himmelb(l)au:


Wolf D. Prix presents 'Energy Roof' in Perugia, Italy

Wolf D. Prix, Design Principal and CEO of COOP HIMMELB(L)AU presented the design for the 'Energy Roof' during a press conference in Perugia, Italy, today. 'Energy Roof' is part of the research project ‚Walking through the History' of the University of Perugia. Beside the archaeological study this research comprised also the creation of an architectural icon.

'Energy Roof' serves as canopy along Via Mazzini in the center of Perugia and at the same time creates the entry point to the archaeological underground passage leading through the history of Perugia. The passage connects the city center with the mini metro station Pincetto. Historical documents show the existence of the old Etruscan city wall in the area below Piazza Giacomo Matteotti which COOP HIMMELB(L)AU proposes to excavate as part of an underground public gallery space exhibiting the history of Perugia. Openings in the ground of the Piazza Giacomo Matteotti visually connect the underground passage with the 'Energy Roof'.

COOP HIMMELB(L)AU developed the design of the roof with the goal to generate energy for the city. While the orientation of the west wing is optimized in relation to solar radiation, the east wing captures wind. The roof consists of three layers: the energy generating top layer, the structural layer in the middle and a layer on the bottom as a combination of laminated glazing and translucent pneumatic cushions. The top layer includes transparent photovoltaic cells to generate electricity and shade the sun. The orientation of the individual cells is generated and optimized by a computer driven scripting program. Furthermore five wind turbines that are placed inside the structural layer are generating additional energy. Both the roof and the underground passage are energy self-sufficient.

The new paradigmatic design of the 'Energy Roof' creates a distinctive and highly recognizable icon for the city and a statement for aesthetic sustainability corresponding with the ancient buildings of Via Mazzini.

  • fraktal geometry… ehh… why not? but turbine, why? it’s not only making noise but also producing little kW(?). Is the speed and the force of the wind between two building enough? i don,t think so.

  • YUK!!!

    My Username says it all !!! What’s the point of building something so expensive in a town center left in the hands of pushers and junkies…I think Perugia has already spent enough on the minimetro-flop!!!

    architecture can be seen as two sides of a coin. on one we have the modern outlook pushing forward, challenging new designs because what is the point of design if we dont try something new and evolve? however on the flip side there is the aspect that we should still try and preserve our history and restore and conserve. the deisgn isnt too bad but is this really the best place they could have thought of putting this? seriously, im all of the old and new being brought together but this design is frankly a monstrosity. i dont doubt it would have become ”recognizable” but an icon for the city, please, the Italians know far better than to approve this.

    It seems to be like an alien. It doesn’t fit the surroundings and it will disturb people who are living there.
