The Palacio de Congresos Europa's vertical garden
Vitoria- Gasteiz is a city in Spain recognised internationally for combining biodiversity and green spaces via pioneering architecture. Design team Urbanarbolismo and Unusualgreen studios have come together to create a green lush exterior bringing the surrounding ecosystems to the heart of the city.
The vertical garden has a total area of 1492m2, of which 1000m2 are on a hydroponic vertical garden system, the rest of the space is made of climbing plants covering the windows - 33,000 native plants of different varieties from Alava and the Basque Country were used.
The objective of the project was to improve energy consumption at the Palace of Congress. Unusualgreen installed two gardens on the corners of the building using aluminum and steel structure to support their 'f + p preplant' hydroponic system, adding a thermal resistance of 2,644 m2.K / W. This allows a 270% increase on the existing facade's insulation, resulting in energy savings.
The design represents the ecosystems that live in the surroundings of the city of Vitoria-Gasteiz. Combining the wetland vegetation of Salburua, agricultural field plots of Alava, the ecosystems from the loamy hills and beech forests from the mountains of Vitoria.
LED lights were also integrated into the system showing off the magical greenery and providing a spotlight for the building at night.
