Gioia 22 is a new, landmark office tower developed by COIMA and designed by international architectural firm Pelli Clark Pelli Architects.


The building has become one of the most iconic skyscrapers in Italy and a world benchmark in terms of energy efficiency, thanks to its innovative design that incorporates unprecedented standards of technological innovation and environmental sustainability, such as Onyx Solar’s Photovoltaic Glass.

Permasteelisa Group has partnered with Onyx Solar to develop the Photovoltaic Façade of this building, divided on 26 floors above ground reaching 120 meters, located in the heart of Porta Nuova Garibaldi, in Milan.



The Photovoltaic Glass manufactured in Crystalline Silicon Technology is integrated into the entire façade of the skyscraper as a spandrel, thanks to which it is capable of producing energy equivalent to the average needs of 300 residential homes.






The high-performance façade features many technological and sustainable elements such as the 2,345 units with integrated Photovoltaic modules, which exceed 5,000 m2 of the surface.





Gioia 22 is the first building of its size designed and constructed according to Near Zero Energy Building standards (NZEB).


The skyscraper, which produces 65% of its energy needs from renewable sources, seeks to obtain LEED Platinum® certification.






Gregg Jones“The original shape of the Gioia 22 tower is the result of the confluence of two urban fabrics, and at the same time the response to the need to optimize light and solar energy. The combination of these two factors has resulted in the singularity of a dynamic form capable of authentically expressing its particular placement within the Milan skyline”.
