Palacio de Congresos de Vitoria-Gasteiz

The Vitoria-Gasteiz City Council launched a process of enlargement and energy refurbishment of the Europa Conference Centre, built in 1988, to improve the city’s congress and exhibition offer, and at the same time increase its energy efficiency, seeking to set a benchmark for other buildings. With the entire refurbishment, this public building has achieved savings of 70% compared to its initial consumption.

More than a building, an experience: Palacio Europa stands as an icon of sustainable architecture in the centre of Vitoria-Gasteiz, a city renowned for its commitment to the environment.

Its avant-garde design not only offers a modern and attractive aesthetic, but also incorporates the highest standards of energy efficiency and respect for the environment.

The building is distinguished by its spectacular vertical garden, a pioneer in reproducing native ecosystems with more than 33,000 plants.

Certified energy efficiency: The Europa Palace is not only beautiful, but also intelligent. Its design and construction under the Passivhaus standard have earned it prestigious recognition for its energy efficiency, including the certificate awarded by the US Green Building Council. This means that the building consumes 75% less energy than a conventional building, which translates into significant cost savings and a lower environmental impact.
