• Opengela Roadmap and Opengela Communities are two tools created by Cíclica and the Polytechnic University of Catalonia (UPC), with funding from the Basque Government.  

• With this method it is possible to work on a hypothesis of what will happen to each building in the Basque stock, and it provides key information for the Digital Building Register and the Renovation Passport. 

• Ana Telleria, head of Neighbourhood Regeneration and Urban Agenda of the Basque Government, assures that “the main objective of these two tools is to facilitate decision-making by all the agents involved in housing renovation: Administration, professionals, companies in the sector and residents, whom we want not only to involve in the process but also to empower”.

The Basque Government, in collaboration with Cíclica and the Polytechnic University of Catalonia (UPC), has developed two pioneering tools that will transform the management and planning of urban regeneration: Opengela Roadmap and Opengela Communities. These advanced solutions facilitate the architectural, energy and economic diagnosis of each building in the Basque Country, providing a unique framework for decision-making and neighbourhood involvement in housing renovation.

Ana Telleria, head of Neighbourhood Regeneration and Urban Agenda of the Basque Government, highlighted that “these tools are a decisive step towards a more sustainable and equitable Basque Country”. According to her, “they allow us to look to the future with solid, data-driven planning, ensuring that all communities, regardless of their size or vulnerability, can benefit from change”.

Comprehensive diagnosis with Opengela Roadmap

Opengela Roadmap is a key tool for public administration, designed to create roadmaps towards the decarbonisation of the Basque building stock with a view to 2050. Using UBEM (Urban Building Energy Model) technology, it analyses each building in the territory, identifying priorities according to its location, year of construction, energy performance and other indicators such as energy vulnerability. This makes it possible to generate customised scenarios for each community and to evaluate the effectiveness of public policies, such as subsidies and grants.

In the words of Telleria, “thanks to these new methodologies, and as part of the research that has enabled a first approach to the long-term Action Plan for improving the energy efficiency of the Basque Country’s building stock, an architectural, energy and economic diagnosis has been made of all the residential buildings in the Basque Autonomous Community”. In this case, the homogenised data obtained from the cadastres of the three territories have served as the basis for generating a database of buildings in the Basque Country.

Thus, through the Roadmap tool, the user can select and prioritise different sectors of the stock according to specific characteristics: geographical location – provinces, municipalities and their aggregated areas, districts or streets -, type, year of construction, energy performance or previous segmentations included in the database such as, for example, energy vulnerability. “This allows you to create different scenarios and, depending on the data entered, it is possible to obtain a renovation roadmap that covers all the buildings considered in the selection analysed, and ultimately, the entire stock as a whole”, explains Cíclica.

It is therefore possible to test and confirm the effectiveness of the policies associated with the inputs -subsidies, grants, etc.- through the results obtained. These can be checked in terms of, for example, final and cumulative performance improvement, cost distribution over time by the stakeholder or demands on the industry. The best options for the whole stock and for each of the segments under consideration can then be assessed.

According to Telleria, “the Roadmap tool is an instrument of analysis and strategic planning and scenario modelling to check the different variables that the public administration can introduce into the equation”. Moreover, she states that, “depending on the optimisation criteria used, it also provides a renovation itinerary for each building, organising the different interventions over time, together with their economic and environmental balances and in line with the evolution established in the minimum energy efficiency standards”.

Furthermore, working with the entire building stock -or only with some of its segments- implies having tools that allow for a quick visualisation of the information. Beyond the synthetic results of the scenarios, a precise visualisation of the geographical distribution of the characteristics of the building stock must be provided at various scales. In this sense, the Roadmap tool integrates a viewer of the building stock, which allows data to be extracted and offers a highly operational visualisation that facilitates decision-making.

Digital Building Register and Renovation Passport

Consequently, once a roadmap for the stock -or a segment of it- has been selected, a set of data on each building is available to provide an individual draft for the Digital Building Register and the Renovation Passport. In this way, a top-down view of each building in the stock is obtained, together with its evolution over time.

This information defined for each building can also be used to search for synergies between projects. The tool offers the possibility to develop these urban projects by planning the aggregation of interventions of different buildings in the same street, square or neighbourhood. It is at this urban scale where, based on the drafts generated by the tool, architectural quality criteria are introduced in energy renovation and urban regeneration projects.

Neighbourhood empowerment with Opengela Communities

On the other hand, Opengela Communities focuses on involving owners and tenants in the renovation process. Through a web platform, neighbours can access the Digital Building Register and the Renovation Passport, receiving technical, administrative, financial and support guidance. In addition, this tool prioritises the most vulnerable communities, tailoring support plans to their specific needs to ensure an inclusive transition.

“We want this transformation to be not only technical, but also social”, explains Telleria. The Opengela Communities tool helps “residents to become active agents of change, facilitating their participation in a process that might have seemed inaccessible before”, adds Telleria.

Seven main groups of indicators are considered for this tool. The architectural ones refer to the current situation of the building stock. The energy and economic ones allow to analyse the impact of renovation measures. Three categories of use, construction system and devices show additional information about the building and are improved by the local technician of the neighbourhood office with the support of the neighbour.

The visualisation of the Digital Building Register is based on a prototype with detailed building information; a renovation and financing plan; and a decision support system. This support can be provided face-to-face or virtually, and covers tasks related to the consolidation of the draft of these two documents as required.

In conclusion, these tools not only represent a technological advance, but also a commitment to sustainability and social cohesion in the Basque Country. With Opengela Roadmap and Opengela Communities, the Basque Government is positioning itself as a benchmark in urban regeneration, leading the way towards a greener and more equitable future.

Two years ago, the transformation of part of Beraun (Errenteria), one of the 21 neighbourhoods belonging to the Opengela programme, began. As a result, 63 homes have been completely refurbished and the public space has been urbanised and improved. This urban regeneration plan has been promoted jointly by Errenteria City Council and the Basque Government and has also involved the participation of the neighbourhood.

It should be noted that, as the Basque Government indicates, ‘the operation as a whole has made it possible to carry out the necessary actions to guarantee the structural, constructive and habitability adaptation of the blocks and has served to improve their energy efficiency by installing ETICS and a ventilated façade’. Likewise, to regenerate the public space and improve the facilities, two new squares have been created in Beraun street; the forms of sustainable and safe mobility in this street have been improved and lifts have been built between Juan Crisóstomo, Aita Donostia and Mauricio Ravel streets. The construction of the new car park building at the end of Beraun street and the surface car park in front of the Basque pelota court have also been carried out.

The plan has also included the refurbishment of the Aldakoenea building for use as a multi-purpose municipal facility by creating a space for the ZU! service to attend to citizens; another for social services and, finally, one managed by the library for the use of citizens.

However, as the Regional Minister for Housing and the Urban Agenda, Denis Itxaso, specified during his visit to the neighbourhood, ‘the department is continuing with the urbanisation and improvement work on the public space’ in order to complete the works as soon as possible.

All this would not have been possible without the support and advice provided by the neighbourhood office (Opengela) to the neighbourhood and community administrators, acting as a one-stop shop for the application and processing of subsidies and carrying out the coordination work between the neighbourhood and the administration for the implementation and execution of the refurbishment work. In fact, the Regional Minister has highlighted ‘the key role’ of the office in the management and accompaniment of the project to the neighbourhood.
