Revitalizing urban blocks
across Europe.
DECUB
The DECUB project tackles the intricate challenge of achieving sustainable urban development and regeneration with a special focus on circular economy principles applied at the urban block level. An “urban block” is understood as a group of buildings delineated by streets and/or public spaces. DECUB explores holistic strategies to decarbonize urban blocks across European cities, integrating digital tools, community engagement, and cultural heritage preservation. The project aims to test and compare interventions—ranging from soft renovation to deconstruction and reconstruction—based on environmental, technical, social, and economic criteria. By prioritizing the reuse and recycling of materials, DECUB addresses sustainability challenges while aligning with EU policies like the European Green Deal and the New European Bauhaus.

We develop a holistic approach

Multiscalar Framework
Combining urban agglomeration-level insights with detailed urban block-level data to scale up solutions across Europe. This approach ensures that local interventions contribute to broader sustainability goals, fostering cohesive and impactful urban transformation.

Archetype Categorization
Identifying and classifying urban blocks based on key characteristics such as building typology, heritage value, environmental exposure, and adaptability. This method enables tailored strategies for decarbonization and circularity, optimizing interventions for diverse urban contexts.

Urban Block Level
A deep dive into the urban block as the core unit of transformation—analyzing material flows, infrastructure, and social dynamics to design scalable, circular, and resilient solutions that fit within the larger urban ecosystem.
Steps for urban block decarbonization
1


At the urban agglomeration scale a Digital Twin that classifies urban blocks along archetypes, which allows to scale up solutions adopted in specific urban blocks to other cases and transfer materials/components from one to another archetype.
2


At the urban block scale a detailed Digital Twin that calculates several environmental performance indicators, including Life Cycle Analysis (LCA), Material Flow Analysis (MFA), risk identification potential scenarios and evaluation of solutions.
3


Development and compilation of strategies and solutions for each urban block archetype. Community engagement and stakeholder collaboraion will be developed in the entire duration of the project through 3 Living Labs: Zaragoza, Verviers and Heerlen.
An international consortium

Geospatiumlab (GEOSLAB)
GEOSLAB is an SME (as defined by European Union) created in 2007 as Spin-off of the University of Zaragoza (Spain) to transfer the technology and knowledge developed by the Advanced Information Systems R&D Group (https://www.iaaa.es/) in a more than 15 years career. The team is composed mainly by software engineers with proven experience and specialized background in the field of Geographic Information Systems. The company is specialist in management, publishing and visualization of geolocated information. It holds a wide experience in the scope of Spatial Data Infrastructures (SDIs) and the implementation of the INSPIRE Directive (2007/2/CE) both at national and European level.

Sociedad Municipal Zaragoza Vivienda (ZVIV)
Zaragoza Vivienda (ZV) is an entity of Zaragoza City Council dedicated to urban regeneration and housing. Founded in 1.953, its objective is to improve degraded urban areas by participating as an active stakeholder in the real estate market, helping to reduce land and buildings prices. With more than 50 years of experience, ZV has adapted its actions to meet the social needs of Zaragoza residents, while maintaining its social commitment. Currently, ZV`s main lines of action are social management, property development, refurbishment and resident innovation through EU projects. ZV contributes to promoting, designing and managing urban policies that, based in sustainability criteria, generate social and environmental value and are effective in improving living conditions in the city, responding appropriately to the need for housing and the ageing of neighbourhoods.

Mines Paris (MINES)
Mines Paris, through its Center for Energy Efficiency of Systems (CES), has been conducting research on Life Cycle Assessment (LCA) of buildings and districts since 1992, with notable contributions in recycling and circular economy modeling. CES has pioneered dynamic, prospective, and consequential LCA at the urban scale. It leads the Eco-design of Buildings and Infrastructure Chair, a partnership with three ParisTech graduate schools (MINES ParisTech, École des Ponts ParisTech, and AgroParisTech), focusing on reducing the environmental impact of buildings through eco-design tools. CES also represents France in the International Energy Agency's EBC Annex 89 program, dedicated to evaluating environmental impacts of net-zero buildings.

Zuyd University of Applied Sciences (ZUYD)
Zuyd University of Applied Sciences, a public non-profit institution in the Netherlands, operates across Heerlen, Sittard, and Maastricht, with 29 professorships and over 14,000 students. It significantly contributes to professional and regional development. The Smart Urban Redesign (SURD) research center, led by Professor Dr. Nurhan Abujidi, focuses on creating vital, circular, and energy-positive neighborhoods by developing and applying circular solutions. Zuyd integrates research and education within hybrid learning configurations that combine research, education, and professional practice in multidisciplinary, multi-level, and multi-sectorial contexts. The SURD center specializes in integrated design, circular design strategies, circular assessments (e.g., Level(s) and LCA), transition system analysis, and people-centered design.

Technische Universiteit Delft (TUD)
Delft University of Technology (TU Delft) is one of the leading technical universities in Europe, renowned for its expertise in engineering, technology, and sustainable urban development. Through interdisciplinary research and innovation, TU Delft contributes cutting-edge knowledge to address complex urban challenges, such as climate adaptation, housing, and energy transitions, fostering collaboration between academia, industry, and policymakers.

Gemeente Heerlen (HEER)
Gemeente Heerlen is the local government of Heerlen, Netherlands, dedicated to revitalizing its urban environment and fostering social and economic development. With a strong emphasis on sustainability and innovation, the municipality leads efforts to improve housing, public spaces, and community well-being while addressing the unique challenges of post-industrial regeneration in the region.

Ville de Verviers (VERV)
Ville de Verviers is the municipal government of Verviers, Belgium, committed to improving the city’s urban fabric and quality of life for its residents. With a focus on sustainable urban development, it actively works on regenerating public spaces, fostering community engagement, and addressing challenges related to housing, mobility, and environmental resilience.

San Jorge University (USJ)
Arquitecturas Open Source (AOS) research group, part of the School of Architecture and Technology (EARTE) at Universidad San Jorge (USJ), specializes in spatial planning and innovative urban strategy methodologies based on data. They are experts in integrating Geographic Information Technologies with the creation of dynamic, interactive, and interoperable digital platforms. Their research focuses on harmonizing and analyzing large-scale spatiotemporal urban data, with applications in energy performance assessment and mobility scenario simulations (https://aos.usj.es).

University of Liège (ULIEGE)
LEMA is a research group of the Urban & Environmental Engineering Research Unit of the University of Liège (www.uee.ulg.ac.be).
