The second edition of Solar Decathlon Europe has come to a close in Madrid with the Canopea House winning the competition. Designed by the Rhône-Alpes Team from the Ecole National Supérieure d'Architecture de Grenoble, France, the house has scored highest in Comfort, Architecture,
Innovation and Operations.
The second place is for Patio 2.12 from Team AndalucÃa, a house with an interesting cooling system based on evaporation that has excelled in Energy
Efficiency, Balance of Electricity and Communication.
Patio 2.12 is a construction with four
prefabricated volumes organized around an enclosed courtyard. Each
volume hosts a different function: sleeping, cooking, living and technical.
Volumes are internally lined with cork panels from recycled wine corks and externally with clay panels.
The courtyard roof is a triple-glazing with leafy-looking external louvers. The glazing can open to release hot air whereas the louvers are fixed and rotate to close or open position. When closed, their irregular shape and metal finish give a lovely shade to the courtyard. Shame that the overhead-glazing hasn't got sufficient pitch to avoid ponding and nasty stains have grown throughout the glazing.
Patio 2.12's cooling system is smart. It follows the principle of the
traditional botijo, the unglazed clay jug used in Southern Spain to
keep water. The botijo (pictured below) cools water by evaporation. Once
filled and placed in the sun, its porous material allows water to filter
through it and to evaporate once in contact with the outside dry air. Evaporation requires thermal energy which is extracted from
the water inside the jug, cooling it down up to 10C. The cooling system of the house works the same way. It relies on ceramic
hollow cladding panels. Water drops through the panel's cavity and when it evaporates, it cools the cavity. An air draft brings the cool air into the building.

The Canopea House by the Rhône-Alpes Team is one of the few projects that considers the urban context. The team, concerned by the lack of urban space, has designed a house that can be stacked into towers, thus helping to contain urban sprawl. The "Nanotowers" incorporate features such as farms to grow food and a communal space at the top of the building with a summer kitchen and a laundry room. A buffer zone around the building lowers the heat loss in the winter and protects from the sun in the summer.
The Ekó House by Team Brazil is a lovely construction surrounded by bamboo sliding screens. The bamboos are differently spaced in East and West facades. The house has a dry composting toilet and treats it grey water with macrophyte plants.
