Sonia Álvarez Díaz, DTERBIM Project Coordinator at CARTIF: "One of the greatest impacts of DTERBIM will be to demonstrate how digitalisation can transform the way we design, renovate and manage buildings"

Delivering a Horizon Europe project goes far beyond developing innovative technologies. It also means bringing together partners with different areas of expertise, aligning technical and strategic objectives, and ensuring that research translates into practical solutions. In this edition of our #DTERBIMVoices series, we speak with Sonia Álvarez Díaz, Project Coordinator of DTERBIM and researcher at CARTIF Technology Centre. With a background in architecture, Sonia shares what motivates her and why collaboration is key to driving the digital and circular transformation of Europe's construction sector.

Sonia Álvarez Díaz, DTERBIM Project Coordinator.

To begin, could you tell us a little about yourself? What is your background, and what does your work at CARTIF focus on today?

I am Sonia Álvarez Díaz, an architect and researcher in the Energy Division of CARTIF Technology Centre, within the Energy Efficiency Area. I hold a PhD in Architecture, focused on the use of BIM and advanced digital technologies for energy-efficient building renovation projects, as well as a Master’s degree in Technologies for the Protection of Immovable Cultural Heritage.

My current work focuses mainly on the application of digital technologies to energy efficiency management, building and urban renovation, and semantic 3D modelling through GIS and BIM technologies, as well as their connection with Digital Twins.

What aspects of your work do you find most rewarding? What continues to inspire and motivate you?

What I enjoy most is the variety of topics I work on, mainly related to the use of digital technologies in the built environment to improve energy efficiency, from building scale to city scale. I also value the more practical side of my work, such as on-site data collection for building digitalisation and energy audits, as well as the development of decarbonisation plans and energy improvement strategies. This keeps me closely connected to real buildings and real challenges.

What keeps me motivated is learning. I really enjoy learning about new topics, proposing new ideas, and applying them in both proposals and real projects.

As DTERBIM's Project Coordinator, what are your main responsibilities? What challenges are you adressing?

Within DTERBIM, I have several responsibilities. My main role is as Project Coordinator, but I am also involved in the technical development of the project. As Project Coordinator, my focus is on ensuring that all technical, organisational and strategic elements of DTERBIM move in the same direction. I would say this is one of the main challenges of the project.

"As Project Coordinator, my focus is on ensuring that all technical, organisational and strategic elements of DTERBIM move in the same direction."

Looking at the first months of the project, what have been the main achievements? And what priorities lie ahead?

From a coordination perspective, starting a European project always requires a significant effort in terms of management, administration, and technical alignment. During these first months, we have focused on setting up the project structure, supporting the consortium, clarifying initial questions, and addressing the first issues that naturally arise in a project involving 18 partners and three real demonstration sites.

One of the closest objectives at the project level is to have the first definition of the BIM-based renovation and new construction processes across the complete building lifecycle. This will be a collaborative process, based on the analysis of stakeholders' needs, barriers, and challenges in business-as-usual circular and energy renovation practices. This participatory approach is essential to ensure that the solutions developed in DTERBIM are relevant, scalable, interoperable, and useful for the sector.

What impact do you hope DTERBIM will have on the construction sector?

At the general project level, I believe one of the greatest impacts of DTERBIM will be to demonstrate how digitalisation can transform the way we design, renovate, and manage buildings, integrating circularity to achieve more efficient and sustainable processes.

As a result of our work, I would like to see the Architecture, Engineering, and Construction (AEC) sector move towards a more innovative, sustainable and connected model, where Small and medium-sized enterprises (SMEs) in particular can engage more easily with a collaborative digital ecosystem through the DTERBIM Toolkit and its accessible, cost-effective and easy-to-use digital solutions.

DTERBIM 1st press release

From linear to circular renovation: DTERBIM officially launches

The DTERBIM project (Driving Transformation on Energy-efficient and circular Renovation through BIM) has officially launched, marking the start of an ambitious 42-month initiative to transform Europe’s construction and renovation sector. To announce the project’s start, the consortium has released its first official press release, outlining DTERBIM’s vision, objectives, and planned pilot activities. Funded under the European Union’s Horizon Europe programme with a budget of €3.83 million, DTERBIM aims to accelerate the shift from linear construction processes to digital, circular, and energy-efficient renovation.

The project officially kicked off on 29-30 October 2025 at the CARTIF Technology Centre in Valladolid, Spain, bringing together 18 partners from eight countries for two days of alignment, planning, and a visit to one of the real-life pilot buildings.

A vision for circular, digital, and sustainable renovation

DTERBIM is developing an innovative, interoperable, and adaptable BIM-based methodology, the DTERBIM process, to make building renovation and management more efficient. By optimising resources such as materials, products, and energy, reducing time and costs, and embedding circularity principles from the outset, the project seeks to transform how buildings are designed, renovated, and managed.

At the centre of this approach is the DTERBIM Toolkit, a suite of user-friendly digital tools, AI-powered services, and Digital Twins, all integrated within an openBIM ecosystem. This ecosystem ensures seamless interaction between tools, robust data exchange, and collaboration across stakeholders, empowering the construction sector to make informed, sustainable decisions throughout the building lifecycle. From design and construction to operation, maintenance, deconstruction, and reuse.

“The DTERBIM project aims to demonstrate how digitalisation can transform the way we design, renovate and manage buildings, integrating circularity for a more efficient and sustainable process. By combining digital technologies such as BIM, Artificial Intelligence, and Digital Twins, it will help improve material traceability and enable more informed decision-making throughout the building lifecycle. Ultimately, DTERBIM aspires to take a decisive step toward a more innovative, circular, and connected Architecture, Engineering, and Construction (AEC) sector,” says Sonia Álvarez Díaz, Project Coordinator, CARTIF.

Five pilot projects across Europe

DTERBIM will validate its methodology through two virtual pilots and three real-life building demonstrations:

  • A residential historical building in Valladolid, Spain
  • An academic building in Warsaw, Poland
  • A kindergarten and elementary school in Athens, Greece

These pilots aim to deliver measurable results, including up to 15% reductions in costs and time, 35% improvements in building performance, and 15% of materials saved for reuse, while engaging over 60 SMEs at local and regional levels.

By aligning with key EU initiatives and incorporating participatory approaches, DTERBIM will define and demonstrate a new paradigm for the European construction and renovation sector.

A multidisciplinary consortium driving innovation

The DTERBIM consortium brings together engineering, architecture, computer science, environmental sciences, social sciences, economics, and policy expertise to ensure a holistic approach to innovation and implementation.

Partners include: CARTIF (project coordinator), Mostostal Warszawa, University College London, ICCS - NTUA (Institute of Communication and Computer Systems of NTUA), CEMOSA, CYPE, Contecht GmbH, Live Information System, Buildings Performance Institute Europe, Acciona Construcción, VEOLIA Servicios LECAM, GEOTER, FASADA, Warsaw University of Technology, Hellenic Passive House Institute, Urban Soul Project, Smartflex, and Australo.

DTERBIM is ready to reshape Europe’s renovation sector with digital, circular, and energy-efficient solutions.
