Primary energy need
6 kWhpe/m2.year
(Calculation method : Other )
Being the highest certified Passivhaus building in the world, it implies a huge improvement in energy efficiency. On a building that complies with current regulations, and with an Energy Rating A, the reduction in heating demand will be of 80%!
There are several issues to highlight in this project, which make it an example of global sustainability:
-Construction traditional: It is a really remarkable aspect, the building has been built with construction techniques and conventional materials such as concrete for the structure, brick, plaster, etc. It was a premise to be able to use the same materials that are commonly used by the administration.
-Passivhaus XXL: Its scale has meant that many constructive issues have had to be reconsidered, in order to make it viable in a building of this size. There have been times when there were more than 125 people working simultaneously in the work, it has been vital to have a great organization by the construction company, Sukia, and the Facultative Directorate, #VArquitectos.
-Social housing: There is no typology in which it makes more sense to improve construction in order to achieve the category of passive building or almost zero consumption. In this way, energy poverty situations will be avoided, maintaining maximum interior comfort, and minimizing after sales maintenance.
-Low cost: The budget is within the parameters established by the Basque Government for VPO construction cost. It has been necessary a deep study of all the solutions and materials to obtain the maximum benefits, maintaining the best durability without an extra cost.
Conclusion: if it has been possible in this case and with these premises, we have the certainty that any project developed correctly can meet the necessary requirements to be considered passive or almost zero consumption.
It is therefore a perfectly exportable example, since it does not have a high budget, nor its construction is complex. These are the great advantages so that in any part of the world, adapting to the conditions of each country, a Passivhaus building can be proposed regardless of the type.

Owner approach of sustainability
The objective of this project, besides regenerating a highly degraded urban environment, was to be able to develop a product with the maximum benefits from the point of view of energy efficiency.
Architectural description
The project presents a very resounding volumetry, with its 28 and 9 height levels. This implies that there is a tower as well as a block, and applying the same compositional criteria was really complicated, since they are very different typologies.
