Casa Mecano function as an organism composed by a structure, skin and a mechanism that adapts the its environment. The project maximize the use of passive design strategies through bioclimatic architecture in sinergy with the integration of a Building Management System that operate the glazing vents in order to achieve the thermal comfort levels, adequate for the tropical environment. At the same time, the team designed a manual system that allows the client to change the inclination of a sail, with the goal of controlling the direct sunlight projected inside the house. The project maximize function in the smallest space possible, reducing the footprint and allowing the minimum use of construction materials.
