The plant façade has 1,492 square meters of surface, 1,000 m2 are the vertical garden of the hydroponic f + p system and 492 m2 are of climbing plants that cover the windows. For its plantation , more than 33,000 plants of various native varieties from the area of Álava and the Basque Country have been used.
This vertical façade improves the energy consumption of the Palacio de Congresos, which translates into 270% more insulation over the existing façade, with the consequent energy savings.
The design takes as a reference the existing ecosystems in the surroundings of Vitoria. At the base of the garden, in a steel plinth, the explanation of the ecosystems that the garden reproduces and the plant species that compose it is detailed. 97% of the species used are native to Álava. It is the first vertical garden that reproduces autochthonous ecosystems in the area where it is located.
With the help of native plants, the garden has already been colonized by insects and animals, it has not taken long for birds to be seen on the facade.
Benefits of green facades.
- 1 m2 of green facade generates the oxygen required by one person throughout the year and traps 130 grams of dust per year.
