New construction of terraced houses, each one with 250 sq.m. surface distributed over 3 floors, and garden. Energy performance < 50 kWh/sq.m.
The intervention of the three villas construction is included in an urban residential expansion plan of a small town in the surroundings of Turin. The urban plan of reference requires a traditional construction type, however with some project choices that characterize the building surrounding the area. Each villa has 80 square meters on the ground floor, 80 sq.m on the first floor with sloping roof (average height 2,65 m) and 90 sq.m in the basement.
The three housing units have staggered fronts in order to exploit each one, on one front, the maximum depth of the external arcade space; this choice creates movement in the construction in terms of volume and for the roof layers. The buildings structure is made of reinforced concrete, with brick masonry and wood roofs; the external facade is overall insulated with performances above the legal requirements. The facades partly have a plaster finish and partly are covered with porcelain stoneware tiles, with travertine marble effect, of different elongated format “a correre”. Dormer windows on the attic floors have been conceived as net and squared volumes emerging from the roofs, matching the facades. Another characteristic feature is the sliding blinds on the facade, with the same surface of the window frames, substituting the traditional Piedmontese shutters but retaining their function and the same percentage of darkening. Finally, the porch covering the outer space of the central house (in order to bring more natural light into the rooms otherwise penalized) was realized with a laminated wood supporting structure and covered by sheets of transparent glass.
Each house has a radiant floor heating system powered by a condensing boiler, solar thermal panels producing hot water and photovoltaic modules covering part of the electricity consumption. Re-use of meteoric water for irrigation of the private green areas is expected. The global energy performance index is less than 50 kWh / sq.m., for A2 and A3 energy classes.
For this intervention, Architect Andrea Milano was the designer with architect Marco Miraglio, and was construction site manager and energy consultant.
