GIOIA 22 is a landmark office tower developed by COIMA and designed by international architectural firm Pelli Clark Pelli Architects. The building, which features a retail podium and a new urban public piazza, looks over the Biblioteca degli Alberi Park, a large public park located in the heart of Porta Nuova Garibaldi, another project designed by PCPA for which Permasteelisa Group developed the façade of the towers. GIOIA 22 tower has full floor-to-ceiling glazing, and a gross buildable area of commercial spaces of around 42,000 sqm (452,100 sq ft) divided on 26 floors above ground reaching 120 m (394 ft), redefining the Porta Nuova and Milan’s skyline. The distinctive architecture incorporates unprecedented standards of technological innovation and environmental sustainability. The dynamic form of the tower «is the result of the convergence of two urban grids, and at the same time the response to the need to optimize light and solar energy» Gregg Jones, PCPA Design Principal-in-Charge for GIOIA 22.

The high-performance glass envelope adopted a continuous curtain wall system made up of around 3,000 unitized units with a combination of vertical and tilted low-emission and high-selective glass panels incorporating external solar shading devices (typical module 1,500 x 4,100 mm). Furthermore, the high-performance façade features many technological and sustainable elements such as high-performance triple-glazed glass units, insulated and thermally broken aluminum profiles and around 2,500 units with integrated photovoltaic modules. The extent of the photovoltaic panel surface area - over 5,000 sqm (53,800 sq ft) - is almost equal to the surface area of the entire lot. The façade system, with a 1.5 m (5 ft) modular unit provides flexibility insofar as the composition of the interior space. The Podium façade system consists of a stick curtain wall with aluminum frames; the lobby design façade consists of a façade with point fixing supports. 

GIOIA 22 is LEED Platinum^®.
