An off-grid Spanish winery is harnessing the full power of the sun to ripen grapes and turn the fruit into wine. Local studio Munarq Arquitectes designed Son Juliana’s winery that’s entirely powered by renewable energy on the Spanish island of Majorca. The low-lying, prefabricated concrete structure was built in just 15 days and uses natural materials to blend into its surroundings.

Built facing the Tramuntana mountains in the distance, the off-grid winery lies low to the flat, clay terrain in a linear shape informed by the landscape and wine production process. The grapes enter the entrance to the east, where it then passes through several processing rooms until the wine is bottled and labeled and finally put on display and tasted in the sales room at the west entrance. The 1,300-square-meter facility can produce 40,000 liters of wine each year.

The winery’s prefabricated concrete structure is clad in marés, a local sandy stone, for the facade and lined in ceramic bricks for the interior. Powered entirely with renewable energy, the winery keeps cool with passive ventilation and use of concrete and stone walls, as well as the sloping cork-lined roof, for insulation. Taking advantage of the earth’s thermal mass, the architects built the winery in the basement to meet the special temperature and humidity requirements.

“The retaining walls are stone gabions to take advantage of the thermal mass and soil moisture that remained during the summer,” wrote the architects. “The contribution of ventilation and temperature is carried through pipes connected to geothermal heat pumps.”
