An alpine shelter dedicated to Carlo Mollino was built in the Walser territory of Gressoney Saint Jean in Valle d’Aosta at an altitude of 2100 m above sea level. The original design by Carlo Mollino, an important architect, lecturer at Turin University Faculty of Architecture, FISI ski master, director of Coscuma, the schools and ski teachers’ commission, as well as photographer, was put forward again by the Turin Polytechnic research group coordinated by the architect Guido Callegari, the project’s creator and scientific manager.
The research team drew on the experimental character of the original design which, in the framework of the Concorso Vetroflex Domus (1951) and the X Triennale of Milan (1954), was a manifesto for experimentation in materials and innovative construction techniques.
The example of Passive House built with the participation of Isover Saint-Gobain meets the standards provided for by the ClimateHouse protocol class A gold (< 10kWh/m².yr). The project re-proposes, at a distance of fifty years, one of Carlo Mollino’s ideal houses, Casa Capriata, an experimental prototype in wood designed for the X Triennale of Milan (1954). The original 1954 project, an unfinished work of Mollino, was built thanks to the support of the autonomous region of Valle d’Aosta, the municipality of Gressoney Saint Jean and the technical participation of some sponsor companies, among which Isover Saint-Gobain.
The shelter, an aerial architecture lifted from the ground that stands along the Walserweg in the Gressoney ski district, is an energy efficient building constructed according to the standards provided for by the ClimateHouse protocol class A gold (optimal thermal insulation, insulating shutters and glass panes, excellent airtightness and heat recovery system have removed the need for active heating). The major heat sources are the sun and the heat recovered from the recycled air: natural, renewable and inexhaustible energy sources. The use of the G3 insulating mineral has also permitted high sound absorption performances to be reached.
