Bodegas Portia is a 12,500 square-metre facility capable of producing one million bottles of wine per year. Since the site that it sits on has extremely cold winters and hot summers heating and cooling energy expenditure was a key consideration when designing the building. Foster + Partners incorporated a deep overhang on the roof to shade and the building and keep it cool during hot days. The building is also partially embedded right into the landscape, which helps regulate internal temperatures. In addition, there are PV panels on the roof to collect solar power.
Another interesting feature of the winery is that it actually uses the slope of the land that it sits on to aid in the wine-making process. A road rises to the roof of the building where the harvested grapes are delivered straight into the hopper. Since gravity is doing the work, less electricity is needed and damage to the grapes is also minimized.
