This building is part of the Development RCS Media Group Headquarters

The project took shape from the demolition of the old building Rizzoli, standing on the street with a perfectly simple elevation. Facing the courtyard, the volume presents some deflections that change the overall homogeneity. The tension is enhanced by the use of a fully glazed façade. The rationality of volumes gives this building a sort of abstract rigor, which interprets the conceptual dimension of production of information which is the core business of the building occupier. The deflections of the façades are, however, also a way in which this building interacts with the environment, especially on one side as it is volumetrically connected to the adjacent buildings of the Rizzoli publishing house. On the other side the deflection helps the double height of the main entrance to connect with the internal courtyard. The vertical bands of the facade come from the remodeling of the language used for the entire development, thus allowing a unitary reading throughout the development. It has also given the opportunity to deepen the relationship between the external chromatic/perceptive system and the internal performance/functional use. Given the demand for work spaces, the functional program has been very accurate in locating units of offices and open space, and it has created an equally rigid definition of the openings. The main elevation treatment defined by the opaque/transparent façade system has created a very regular theme throughout the building. The simple rhythm was complicated by the use of coloured spandrel panels which tend to destroy the regularity, increasing the overall interest in the façade.

The technology

The building named A2, facing Via Rizzoli, is featured by a rectangular layout with a cusp connection on the internal courtyard. It consists of 7 levels with 5 entrances: two at ground floor on Via Rizzoli and three at level -1, on the internal courtyard. The technology of the building envelope is based on the development of a structural silicone unitized façade system with High Performance glazing and trichromatic spandrel fascia panels. The request of the client to achieve high standards of functionality and design has been pursued through the application of double glazing with double coating (H.P. in face 2 and Low-e in face 3) and a system of sandwich panels consisting of a low-iron toughened glass pane, enameled with a triple fritted band effect. The extruded aluminum PPC RAL 7022 has been bespoke designed in order to provide the best performance in terms of energy saving in compliance with the project structural and acoustic requirements. Special attention to energy performance, with a result of average thermal transmittance lower than 1W/m2°K, has allowed the certification of the entire building as Energy Efficiency Class A (< 29 Kwh/m2 in compliance with the Regional Law 24/2006). This building envelope has also ensured sound-resisting values higher than 43 dB, photochromatic values for the glazed areas of: light transmittance (LT) 52%, solar factor (G) 42%, external light reflection (ELR) 34%. In order to achieve the right colour balance for the final product, the architect has experimented with different combinations of external light reflection and light transmittance. The structural units have been fully pre-fabricated in Focchi’s factory, with typical dimensions of 2050L x 3800H and total weight of 350 Kg, whilst the top level consists of double height units which dimensions are 2050 L x 5700 H and a weight of 550 Kg. The trichromatic effect of the building has been designed with the juxtaposition of the enameled glazing divided between the total quantity of 800 units.
