The architecture and construction of the Shelter and Regional Hostel in Frasco are designed in order to reduce the operating costs of the structure and its environmental impact.

The typological choices lead to the formation of a space veranda along the entire length of the south facade, and from this comes the opportunity to exploit the effect of solar radiation inside the building by reducing energy consumption, like a passive house. During the summer months, instead, the veranda will be ventilated with different openings, bringing back its use to that of the gallery. The walls of the north, east and west are rather well insulated to minimize heat loss in winter and reduce overheating in the summer. However heating in the main room at the ground floor is guaranteed by a fireplace.
