Abstract
In years 1980 the “brutalist” and “monumentalist” architecture went even in Italy, and in Potenza, and it finds some interesting examples, such as the building designed as the home of the Mediterranean Bank. A monumental building, all in reinforced facing concrete and curtain walls, with refined proportional relationships, and so devoid of insulation (annual heat demand of 69 kWh/m3 year), that its management has become unbearable from the economic point of view, so it was abandoned a few years ago. Aim of this work was to define a design methodology that preserves all the qualities of architecture, but at a cost that is economically bearable and made the building energetically efficient. This was done by allying a very thick and efficient isolation, protected by a ventilated continues rainscreen, finished with several layers of a thin plaster with a bèton-like effect, which determines a morphology that, while different, recalls the original. The curtain walls were doubled with a double skin façade, whose performance has been optimized with a purpose created software. The huge skylight roof of the interior atrium has been doubled with a new, of different trend and thermally more effective. The roof was covered with photovoltaic panels. The result is an annual heat and refrigeration demand of 17 kWh/m3 year, at a cost of 20,000 €/m2, quickly depreciating, due to savings in operating costs for air conditioning (from €104,800.00 to €14,700.00 per year).
