Patio 2.12-Eko House-CEM’ Casas Em Movimento-Ekihouse-Astonyshine Designs of Solar Decathlon Europe 2012


Dear Friends & Visitors/Viewers/Readers,

(Please click on red links, below)

Please allow me to share our next sequence of designs at Solar Decathlon Europe 2012 at Madrid, Spain:

This is a composite of five designs of Solar Decathlon Europe 2012: Patio 2.12 of Andalucia Team of Universidades De Sevilla, Jaen, Granada Y Malaga of Spain;Eko House of Team Brazil of Universidade Federal De Santa Catarina Universidade de Sao Paulo of Brazil;CEM’ Casas Em Movimento of CEM+NEM Team of Universidade Do Porto of Portugal;Ekihouse of EHU Team of Universidad Del Country Vasco of Spain;and Astonyshine of Astonyshine Team of Ecole Nationale Superieure d’Architecture Paris-Malaquais Universita Di Ferrara Ecole Des Ponts Paristech Politecnico Di Bari of France-Italy.

In the first design of this clip, it is the Patio 2.12 of Andalucia Team. During winter, the patio becomes a greenhouse;its glass envelope captures solar radiation and the heated air is conducted to the conditioned rooms. At night the patio and room openings are closed, in order to decrease energy lost through the walls and to use the patio as a thermal transition between the conditioned inside and the open outside. During summer days, the solar radiation on the roof is controlled by the pergola, folding the glass panels and “opening” the patio, and letting the air flow through the vertical walls. Different wind pressures over the walls promote a continuous airflow through the patio. At night, the glass cover is extended and the airflow becomes horizontal through the opened walls of the patio.

In the second segment, we welcome Team Brazil to Solar Decathlon Europe for the first time ever. Team Brazil is the only entrant from Americas (North & South Americas). Their Eko House construction is more concerned with the design and building process rather than high technology. The emphasis is in the human sustainability concept. Detailed description of this house will be found at:

The third, “CEM’ CASAS EM MOVIMENTO”, House of Movement, is a house that tracks the sunlight;this enables its ability to optimize production of solar energy, reduction of heat consumption and reduction of interior lighting requirements. The house feeds itself from the sun following it as it rises and sets by a movement of approximately 180% from east to west. This sunflower effect, combining with movements of solar panels, maximizes solar gains. The production of energy from this house will be 2.5 times greater than the energy consumption needs of the house. Every movement of the house creates new interior and exterior spaces, adapting the house to one’s daily life throughout the day. More detailed description of this house is at:

The fourth, Ekihouse, of EHU Team of Spain, focused on reducing its energy needs and taking advantage of the natural resources of the location and use innovative systems to create the proper conditions for living. For more details of this house,

The fifth and last design of this clip, Astonyshine of France-Italy, aims at integrating energy efficient technology with solar powered architecture, by dealing with six key issues: use of freestones, concentrated solar power systems (combining solar PV and thermal), control of PV field with electronic systems embedded into each module to extract maximum energy, research new design, material, and technology, search for optimal illumination (natural and/or artificial), and integration of architectural and structural design.
