The Unipol office tower, built in the Italian city of Bologna, is characterized by a set of interesting design choices, among which the certification according to the protocol LEED 2.2 for New Constructions. The architect designed an energy-efficient double skin envelope with horizontal interspaces and with adjustable and automated slats. The external skin of facades is a composition of various elements, considering the different solar expositions during all the year. The south-west façade, mostly exposed to direct sunlight during summer, is an opaque ventilated façade with integrated PV system, aluminum panels and air vents for the technical rooms.
