Europe’s sustainable built environment initiative gains momentum: Built4People Innovation Cluster Network launches to accelerate sustainable innovation

Press release

Today (25 September 2023) the Built4People (B4P) partnership announced the launch of a new network of innovation clusters, to action sustainable innovation and help hit EU climate targets for Europe’s ageing building stock, which is lagging behind in the green transition.  

The B4P public-private partnership (B4PIC) between the European Commission and two of Europe’s leading built environment associations, European Construction, built environment, and energy-efficient buildings Technology Platform (ECTP) and World Green Building Council (WorldGBC) was set up in 2021 to channel around €800 million into research and innovation for the sector. The partners are now calling for clusters of businesses to join the Built4People Innovation Cluster (B4PIC) Network. The B4PIC network will help the industry to scale up new solutions, products and services aligned with the ambitions of the EU Green Deal and New European Bauhaus.

The B4P partners welcome existing hubs or clusters to join the multidisciplinary European network to engage, connect, and scale sustainable innovations across Europe. 

The built environment currently accounts for a staggering 39% of global CO2 emissions, which continue to rise. The EU has a target to upgrade 35 million homes by the end of the decade and new legislation under development may make it mandatory for all new buildings to be Zero Emissions by 2028. Currently however, investments in the sector are way off track, with an estimated annual shortfall of some €282 billion needed to upgrade just the existing building stock. 

Unlocking this investment and delivering on the EU’s ambitious goals requires a major shift in the way sustainable buildings are delivered. The construction sector has not kept pace with productivity gains seen in other sectors in past decades and has been one of the slowest to exploit opportunities from digitalisation.

The complexity and fragmentation of the sustainable built environment ecosystem necessitates the involvement of all players across the value chain and building lifecycle to achieve holistic transformation. However, waiting for innovations to scale organically is insufficient. Innovations require the right conditions and networks to reach the market quickly. The new network of B4PICs will play a crucial role in incubating solutions and accelerating their maturity levels, benefiting companies of all sizes. Crucially, this also means increasing the chances of successful outcomes from the dozens of projects the EU is funding under the B4P Partnership.

Driving productivity, growth, and efficiency

By leveraging their collaborative ecosystems, expertise and resources, clusters within B4PICs can accelerate the development, adoption, and scale-up of green technologies and solutions. Research indicates that innovation clusters yield substantial benefits including:

  1. Increased Productivity: Companies within innovation clusters are around 40% more productive than non-clustered organisations, according to the European Cluster Observatory. Additionally, a study conducted by the Massachusetts Institute of Technology (MIT) revealed that innovation cluster companies experience an average a productivity growth rate of 1.2% per year, compared to 0.5% for non-clustered firms. 
  2. Accelerated Growth: The Global Cluster Observatory reported that companies in innovation clusters experience 2.5 times faster employment growth and generate 18% higher gross value added (GVA) compared to non-clustered firms. 
  3. Scale and Supply Chain Efficiency: Collaboration within clusters can result in up to a 48% reduction in supply chain lead time, positively impacting productivity, as published in the International Journal of Production Economics.

Unlocking the Potential: B4PIC Network’s offer and added value 

B4PIC candidates will be engaged in an evolution or transformation process to enhance their maturity levels. Participants can benefit from:

  • Improved visibility towards the European Commission and the major European stakeholders from across the built environment.
  • Facilitate adoption and uptake of innovative solutions aligned with the New European Bauhaus, thanks to increased awareness of the benefits of innovation and better access to co-financing. 
  • Intensified cross-sectoral and interdisciplinary peer learning from front runners, fostering cross-border cooperation and networking. 
  • Preparation for long-lasting activities within the network of B4P Innovation Clusters, with integration opportunities for subsequent clusters.

Key services and support 

The set-up of this new B4PIC network is supported by the NEBULA project. Funded by the Built4People Partnership, as part of the NEBULA, supports B4PIC candidate clusters with a dedicated timeline and step-by-step integration of the 6 B4PIC success factors, helping clusters to reach maturity levels faster.

NEBULA provides a range of key services to assist clusters on their transformative journey, including:

  • Finance toolbox encompassing public and private funding of innovation
  • Match-making sessions to foster valuable connections 
  • Capacity-building workshops tailored for clusters 
  • Handbook for the New European Bauhaus (NEB)
  • NEB Advisors to support and promote events and materials
  • Peer-learning webinars
  • Dedicated clusters module on the METABUILDING platform 
  • Identification and promotion of EU-funded innovations. 

How can clusters join the B4PIC network? 

Existing hubs or clusters across Europe are invited to complete an expression of interest form. Upon submission, applicants will receive further information regarding the subsequent steps to initiate the application process.

The firsts members of the Built4People Innovation Cluster network, ERAIKUNE (Basque Country Construction Cluster) and ODEYS (Cluster construction et aménagements durables in Nouvelle-Aquitaine), signed the B4PIC charter, confirming their participation in the network on 18 September 2023. These clusters will collaborate to mobilise innovation in the building and construction sector in the Euroregion Nouvelle-Aquitaine, Euskadi, Navarra.

Everything you ever wanted to know on the New European Bauhaus is in NEBULA’s handbook!

NEBULA just published its handbook on the New European Bauhaus, addressed to any person or entity willing to understand the concepts underlying the NEB initiative.

It gives you insights on the origin and what the initiative is about, how to access the community and resources and, most importantly, how you can make your project “NEB by design” and where to get funding to support your NEB project. All of that in the most easily digestible format.

The report is illustrated with plenty of NEB projects examples, organised along the three NEB core values: “Beautiful”, “Sustainable”, “Inclusive”. This facilitates the report’s understanding and will, hopefully, help spark many creative ideas all around Europe!

Do you want to learn more on the New European Bauhaus? Don’t hesitate to also visit the dedicated website managed by the EC, where you can learn even more and get involved in the community.


Stay tuned for the next NEBULA’s activities on the NEB, to come this autumn:

  • NEBULA is gathering a network of NEB advisors, to help spread the word and disseminate NEB information to their own networks. If you are interested to learn and share, contact
  • NEBULA will also organised a series of six peer-learning events, to present NEB projects and expand the NEB principles to communities of practitioners that are not yet informed on the topic. If you foresee a specific need or wish our support to organise a similar event, you can also contact:

We’re looking forward to exchange with you on these exciting topics!

New resources available to support you in finding funding opportunities!

Both reports have been prepared by partners of the NEBULA Project and address innovators and intermediaries of the built environment (SMEs, start-ups, research centres etc.), and particularly innovation clusters and their members.
