Designed as a prototype for a pre-fabricated energy efficient home which could be available to install in just four months time at any site throughout Chile . The two bedroom home was designed based on the modules of SIP panel construction. By working with the exact dimensions, it eliminates material waste and avoids a significant amount of work in the field. A highlevel of insulation is achieved through the use of these interlocking panels. Passive heating, cooling, and ventilation is achieved through the carefully calculated openings and angles of the home.
