Bolueta Towers

The Bolueta Towers, located in the Bilbao neighbourhood of the same name, are, at the time of their construction, the tallest Passivhaus-certified residential buildings in the world.

On the site formerly occupied by the first steelworks in Bilbao, a pair of towers, the tallest of which is 88 metres high, have been erected for the generation of needed subsidised housing.

Both architecturally and in terms of energy efficiency, this tower is a worldwide landmark given its almost zero consumption, derived from the materials used and the airtightness of its envelope.

The almost 3,000 aluminium panels that cover the façade are fundamental in insulating the building. Their design is a nod to the area’s industrial past, as they mimmick mineral coal slabs.
