The new 3ndy Studio base, opened on September 2012 in Vigonovo (Venezia), is a praiseworthy example of architectural recovery and energetic adjustment of an ancient industrial building. The project establishes in an old disused shoes factory which is a characterizing element of the urban and productive fabric of the Riviera del Brenta, between Padua and Venice. When this building was acquired it was in good structural condition, however the disuse and the following neglect during the last ten years, contributed, to set a situation of serious decay: the site looked like a dump, full of waste production due to leather processing, which smelt bad and expelled dangerous and flammables liquids. The recovery project set itself to synthetize the primal structure of the building by a contemporary lecture, giving contemporarily and preserving the historical memory, otherwise would have been lost forever. The renovation of the building allowed us to increase the quality of the inhabitant’s lives and to selfguard in the same time the collective memories of the city. Moreover, the commutation entailed a big energy saving during the steps of building ( recovery of existent raw materials, better use of existent infrastructures, better logistic and transports, reducing waste production). 3ndy Studio moreover focused its project on energetic increasing: the new office was given the eminent Award “Classe A CasaClima”, due to the achievement of the energy saving standard of 26Kwh/mq of medium consumption against the 180Kwh/mq usually spent by a traditional building. At the end of the realization of the building it has been tested by a “blower door test”, in order to verify the hermetic sealing of the casing. The result was of almost n50 0.6/h and so it is compared to a “passive house” or rather this building has no draughts and so has no heating dispersion.
