• The dwellings on Txotena Street (three doorways) and Irumineta Street (four doorways) feature 12 m² terraces, thereby increasing their usable space by 30%.

A total of 84 dwellings in the Otxarkoaga neighbourhood of Bilbao have been extended with new terraces as part of the Opengela urban regeneration programme. The project, carried out by Bilbao Municipal Housing, aims to improve the liveability of small flats through innovative refurbishment solutions.

The buildings involved are located on Txotena Street (three doorways) and Irumineta Street (four doorways). The new terraces, measuring approximately 12 square metres, represent an increase of around 30% in the usable space of each flat. This work forms part of the Orain Otxar regeneration project, run by Opengela.

The project has received funding from the European Union through the Next Generation EU funds, as part of the Spanish Government’s Recovery, Transformation and Resilience Plan, as well as contributions from the Basque Government and Bilbao City Council.

• It has been included in the Commission Notice C/2025/6438 for its comprehensive neighbourhood and housing support model.

Commission Notice C/2025/6438 from the European Commission, released last December, provides guidance to Member States on how to implement the EU Energy Performance of Buildings Directive (EPBD) and improve the efficiency of the residential building stock. In this context, the Opengela project is mentioned as an example of inspiring practice. It states that ‘the Opengela pilot project in the Basque Country offers neighbourhoods advice and support on the administrative, technical and financial aspects of energy-related issues, but also on other relevant topics, such as accessibility for people with disabilities’.

In addition to the one-stop shop service, the document states that Opengela has developed ‘an online tool with an energy map of all buildings in the Basque Country’, which provides ‘an integrated framework to support the development of renovation plans, complemented by estimates of the financial implications at multiple levels: national, regional, neighbourhood and individual housing’. This tool also makes it possible to ‘detect needs, including the identification of the least efficient buildings’ and serves as a starting point for each building to determine its energy renovation needs.

The European Commission includes this experience in a section on household advisory practices, recognising Opengela as an inspiring model for other European regions seeking to accelerate the energy renovation of their buildings.

Since September 2023, the European BIRTUOSS project has been developing the Opengela model, created in a previous project (HIROSS4all, funded by the Horizon 2020 programme), which delves deeper into social, economic and environmental aspects. It also explores ways to scale up building renovation to urban regeneration in each neighbourhood.

In fact, in recent years, this model, led by the Basque Government’s Department of Housing and Urban Agenda, has grown to be implemented in 25 neighbourhoods in 21 municipalities in the Basque Country and is enabling the improvement of up to 2,800 homes. And, at the same time as the network of offices is being extended to municipalities throughout the autonomous community, BIRTUOSS is developing a “living lab” in TorreUrizar, in Bilbao, which is being used as a pilot site to experiment with the advances of this European project.

This new video, led by journalist Gonzalo Loza, shows the progress of the works in the neighbourhood and in the homes, as well as the value of the one-stop shop for the neighbourhood. It also features testimonials from a TorreUrizar resident; the head of the neighbourhood’s one-stop shop, Marina Hornazabal; Bilbao City Council’s Councillor for Housing, Yolanda Díez; and the Basque Government’s Director of Neighbourhood Regeneration and Urban Agenda, Ana Telleria.

Together with the Basque Government, the EU-funded project is being promoted by a public-private consortium made up of the Basque Energy Agency (EVE), Bilbao Municipal Housing (VVMM), the Environment (Aclima), Construction (Build:Inn) and Knowledge and Technology (GAIA) clusters, the CAVIAR research group at the University of the Basque Country (EHU), EDE Fundazioa, Ciclica cooperative (specialising in decarbonisation strategies), as well as companies with expertise in financing (GNE Finance), communication (Gabineteseis) and European affairs (Zabala Innovation), and also two European bodies such as Fedarene (European Federation of Agencies and Regions for Energy and Environment) and the Spanish Green Building Council (GBCe).

Great news for Opengela!

Our project appears in the European Commission’s publication ‘Giving LIFE to Europe’s clean energy transition’ and is one of three examples highlighted in the section on ‘One-Stop Shops for Building Renovation’.

The document was launched during the 2nd Round Table of the European Energy Efficiency Financing Coalition, presented by Commissioner Dan Jørgensen.

We are proud to see how our work is contributing to the clean energy transition in Europe!
