Summary"Magic Box" is a prototype of energy self-sufficient solar house that represented Spain (and the European Union) in the "2005 Solar Decathlon" competition, an event promoted by the U.S. Department of Energy that gathered representatives of 18 universities all over the world which is . Main design premises of the project were: - “Active” Bioclimatic architecture: application of traditional strategies for winter and summertime, day and night, commonly used in Spanish vernacular architecture, implemented by means of new materials and systems. - Attractive integration of solar technologies (Photovoltaics and Solar thermal) and maximum exploitation of their multifunctional possibilities, as energy production and construction elements. - Rational use of building elements such as porches, greenhouses, green roofs, eaves, louvers, sliding panels, and even a “folding” patio. Due to the competition requirements, the PV system was autonomous from the grid and had to be equipped with batteries. To this aim, a commercial technology was selected for the power conditioning (based on AC-coupling principles) that enables both grid connection and autonomous operation mode.
