Located on the edge of the historic town center of Turin, the Torre Intesa Sanpaolo stands 166 meters tall in two parts: a public and technical plinth, and 26 floors of offices crowned by a greenhouse-lookout containing a restaurant, a hall for exhibitions, and a roof terrace. The entire complex is organized around a T-shaped spine consisting of three groups of elevators and staircases on the north side, and a greenhouse-facade that looks south. Set between these two extremes are cores of building services and washrooms, and in this way the remaining bays can be used for office spaces. Rising a standard height of 3.2 meters, the work spaces receive indirect sunlight, filtered through a facade built with a double skin of glass, and are equipped with a system of natural ventilation that takes advantage of night breezes to cool the gap between the double slabs of concrete, which in themselves have a thermal inertia, then releases it in the offices.
