Deliverables:
- Backcasting: skills for the circular building economy / A transnational team analyses which skills are needed now and in the next years by professionals across all parts of the circular building economy.
- Coalition building sessions / Coalitions of the Wiling are developed through local and regional workshops, building on the shared ambition developed through back casting in work package 1. The shared ambition becomes stronger through understanding what stakeholders need to move forward.
- Kick-off / At the kick-off meeting in the Netherlands all CTB partners build a common understanding of how to define circular construction, on which stakeholders are involved locally, and on how to measure progress in the transition towards a circular construction sector.
- Trust Framework Masterclass / Trust Frameworks are an instrument coming from digital development. They are new to construction and circularity. To establish a common understanding an expert will give a masterclass on Trust Frameworks, on how the model was developed for safe data sharing and on how they provide a common set of agreed upon standards, ensuring that all organisations meet the same agreements and allow forgoing additional legal contracts.
- Transition theory masterclass / Circular Trust Building implements the innovative transition theory instruments. To deepen our shared understanding of this theory and its instruments, all partners participate in a masterclass with experts on transition theory.
- Developing on- and offline training for circular building professionals / Training courses teach tangible skills and sensitise building professionals to circular thinking.
- Developing a circular building label toolbox / Labeling of products is essential for circular building, however the current wealth of labels makes it difficult to choose which label to use in supply and demand of products. A transnational team analyses the pro- and con's of different label mixes.
- Matchmaking for Regional Circular Deals / Regional Circular Deals unite deconstruction, design, development, construction, and local authorities around substantial construction or renovation projects. In the Regional Circular Deal all parties involved agree on cooperation to achieve at least 25% reduction of material footprint in their projects
- Backcasting: local preparations / All partners together with their local stakeholders analyse what they need to realise their local goals in circular construction, and in reduction of waste & CO2-emissions. Barriers to circularity plus option to overcome these are analysed.
- Public launching customers: challenging the helix / How do we activate the full potential of local and regional authorities as a launching customer? Building on projects as ProCirc, the 5 public partners develop a strategy to engage all necessary internal stakeholders, provide them with a better understanding of circularity, and develop ways in which authorities can develop and procure circular buildings.
- Workshop: Understanding building professionals / In order to support building professionals from all parts of the (circular) building economy, it is essential to understand these professionals, their motivations, frustrations, dreams and preferred learning strategies.
- Testing the Circular building label toolbox / All partners test the circular building label toolbox. Partners use tools for shared decision making to decide with stakeholders on which mix of labels to use for supply and demand of sustainable building materials. The testing will be monitored and evaluated by the transnational expert team. The outcomes of the tests will feedback into the circular building label toolbox and improves its efficiency and impact.
- Backcasting: stepping up to the transnational level / All partners share their local backcasting analysis in a transnational transition strategy. This strategy provides the framework for transnational learning and cooperation in the work packages 2, 3 and 4.
- WHAT the circular building material economy does when it constructs or renovates / WP1 focused on the WHY and WP2&3 focused on HOW. Building on this WP4 focuses on WHAT. In interactive communication campaigns using a mix of traditional and social media channels partners engage stakeholders in demonstrating the scaled circularity and the resulting (at least) 25% reduction of the material footprint of construction and renovation projects collected in the Regional Circular Deals.
- Awareness about the need for common labels & standards / Scaling circularity is only possible when using common labels, standards and shared knowledge on circularity / material footprint in construction/renovation. Partners will create awareness about this need with stakeholders using traditional offline and social/digital media tools.
- On- and offline training for circular building professionals / Stakeholders throughout the regional circular building value chain ensure the upskilling of their professionals. All partners test the on- and offline training with the own circular building professionals and experts.
- Collecting tools and best practices for educational institutions / Lead by the participating educational and research institutions Circular Trust Building collects tools and best practices that can be used by educational institutions to teach the circular building principles.
- Creating awareness: Why be a frontrunner? / A targeted communication campaign raises the awareness of local/region stakeholders - such as (de-)construction, renovation, maintenance, development, architecture - on the Why of the transition: Why they need to transform their practices for a circular future.
- Digital Building Information Management for sourcing and using circular building materials / Building Information Management systems (BIM) are already common in architecture, engineering and construction. A transnational team will demonstrate how BIM can be used for sourcing and using circular building materials.
- Public launching customers: challenging the helix / Local and regional authorities can act as a launching customer: by developing and or procuring circular buildings they create a critical mass for the transition and provide inspiring demonstrations. To achieve this, the authorities need to share circular insights and solutions with all involved internal stakeholders. Drenthe, Groningen, Roeselare, Bremerhaven and Vejle will implement to test this strategy.
- Matching local policy with EU goals / The CTB transnational expert team analyses EU policies on circularity and on construction, reviews the outcomes of EU-funded innovation projects, connects these with Circular Trust Building and with the partners' local ambitions. The transnational transition strategy enables matching EU goals with local policy, regulations, and support measures.Analysis of how local/regional bottom-up, multi-sectoral, and interdisciplinary action supports EU goals and strategy.
- Digital platforms for supply and demand / A transnational team analyses available digital platforms for supply and demand of circular building materials. Based on the analysis the team adds recommendations on digital supply and demand platforms to the toolbox.
- Develop and test toolboxes for educational institutions / Educational institutions Hanze, Vives, ENSAPL and LNU will jointly develop and test toolboxes to include state of the art circular building skills into their curricula.
- No-regret check: 2050 compatibility / The transnational transition strategy not only calls for forward looking action. It also demands construction sector actors to refrain from actions that endanger or potentially compromise circularity. Transnational development of a no-regret check, assessing compatibility with EU 2050 climate neutrality goal.
- Assessing maturity levels / Partners assess the current circularity skills in their own organisations and with stakeholders. A transnational report on the maturity levels supports the Circular Trust Building upskilling strategy.
- Transnational, digital knowledge base / A transnational, digital knowledge base where insights, best practices, and (organisational, regulatory) frameworks from the community of practice are shared will be set up.
- Developing Trust Framework for Circular Construction / A transnational team translates the Trust Framework model to circular construction/renovation. Implementing the labels and standards, digital platform for supply and demand, and building information management system into a Circular Trust Framework. The Framework enables the implicit trust in small-scale projects to become "scalable" trust. Because each new collaboration between stakeholders is based on the same framework the circular network can grow at an exponential, rather than linear, rate.
- Raising the interest of building professionals' in training & upskilling for circularity / Training and upskilling of professionals are most effective when based on the interest and experience of these professionals. Regional communication actions using traditional offline tools as well as social media create and maintain this interest (and connect to the professional experiences of the target groups).
- Compatibility check / Back casting shows us which actions and developments are needed for the transition towards circularity and the EU goal of a fully circular construction sector in 2050. It therefore also provides a measure to ascertain that actions and developments do not endanger that goal. Applying the transnational developed no regret check, all partners will test and improve how to assess this compatibility and how to act on its outcomes.
- Reaching out to new local stakeholders / The engagement of existing stakeholders is essential to the success of backcasting and the transition to a circular construction sector. The enlarge the impact and accelerate the movement, partners together with stakeholders reach out to new stakeholders through social media and (digital) communication campaigns and invite them to participate, to adopt new solutions and to join in the collective upskilling.
- HOW updated skills are essential for circularity / In a communication campaign using both traditional as well as digital/social media tools CTB partners will demonstrate how updated professional skills are essential for circularity and reduction of material footprint in construction/renovation in order to create and maintain professionals' interest in training & upskilling for circularity.
- HOW labels and Circular Trust Framework are essential for circularity / WP1 created the stakeholder awareness about the WHY of the transition to a circular building material economy. WP2 focused on the necessary skills of the professionals involved. WP3 builds on the awareness and developed skills, and demonstrates the tools: How circularity / material footprint labels plus a Circular Trust Framework scale cooperation. Stakeholders will be reached via an interactive digital/social media campaign
- Mapping + analysing best practices, legal challenges & business cases. / Supported by the transnational expert team, partners map on a regional level their own and their stakeholders' experiences with circular (de-)construction, analyse best practices, legal challenges, and business cases.
- Regional Trust Framework Meetings / In regional meetings the transnational Trust Framework will be adjusted to and implemented in the local situation. Legal aspects and characteristics of the regional (de-)construction sector will be addressed and if necessary included in the Trust Framework.
- Understanding potential supply, demand and current market failure / Workshops with local stakeholders lead to a better understanding of potential supply and demand of circular building materials, and of current market failure. Supported by the transnational expert team partners map the outcomes of these workshops, using the EU taxonomy for circularity.
- Testing Trust Framework for Circular Construction Sector / On regional level the Trust Framework will be tested to enable improvements and to demonstrate how it: Mitigates (first-mover) risks for participants Benefits network cooperation and invites others to join Increases convenience and efficiency, removing the need of much one-on-one contracting The testings will be monitored and evaluated by the transnational expert team.
- WHY transition towards a circular building material economy? / The Circular Trust Building communication and dissemination are based on the Golden Circle: WHY-HOW-WHAT. In WP1 Partners create stakeholder attention and awareness on the WHY of the transition to a circular building material economy. For this, a (digital) awareness campaign will be launched.
Contribution to wider strategies and policies:
- Circular Trust Building contributes to the goals of the European Green Deal in both showcasing the accelerated transition to a circular construction sector and in developing and disseminating the necessary tools. Circular Trust Building also shows how to source circular materials for renovation, and thus acts on the current shortage of materials hampering the EU Renovation Wave.
- Circular Trust Building matches the EU's Circular Economy Action Plan with bottom-up, multi-sectoral and interdisciplinary solutions, which in their turn can be scaled and disseminated EU-wide.
- Circular Trust Building implements the vision of the North Sea Region 2030 Strategy on smart North Sea Region, where circular use of resources and circular economy techniques are widely adopted. With LP Province of Drenthe also providing the chair of the North Sea Commission, Industrial Transition Hotspots will use the full potential of cooperation with and exchange through the commission.
- Circular Trust Building fits EU's Industrial Strategy: achieving industrial transformation and building a more circular economy, through upskilling, innovation and transitioning towards climate neutrality. Circular Trust Building strengthens the Circular Building Material Industrial Ecosystem in line with EU's Industrial Strategy.
