MOLE = MODULO LEGGERO is a light-wooden-construction prototype entirely made by 5X8 (cm) timber frame structure, OSB and gypsum-fiber panels, and thermal/acoustic wood fiber board insulation. DUOPUU designed the prototype to test different ways to build small modern and ecological prefabricated wooden houses with good performance in terms of mechanical behavior and building-physics performance, durability and design. MOLE is going to be assembled by the students of "RED-New technologies in green building" course organized by ITS School of Padua with Bertiato Gianluca Construction Company, under the technical supervision of DUOPUU.
