Drastic's French Demonstrator — scaling up circular office retrofits
Drastic’s French demonstrator (led by Saint-Gobain Solutions France, Saint-Gobain Research Paris, Coramine, Ecophon and Icade) aims to increase the reuse of office space plan products by identifying a business model that allows for the fast market uptake of circular, reusable products.
In June 2024, Clipper Coramine conducted the first dismantling and testing process of modular office partitions in an Icade office building in Plessis Robinson, Paris.150m2 of opaque glass wool and plasterboard partitions were dismantled and packaged for storage in Clipper Coramine's workshop, where they will be refurbished for reuse in another office building later this year, thereby helping to test the Demonstrator’s circular office solution.
Saint-Gobain Research Paris will also conduct further testing on some of the harvested materials, to verify and control their mechanical and acoustic properties for future reuse. So far, a 100% reusability rate has been predicted.
The Parisian retrofit cycle in office buildings is approximately six years, with most ceilings and tiles being landfilled or incinerated for energy recovery at the end of their life. Reusing these products on a large scale could support the necessary decarbonisation of the European built environment and a transition to using more circular practices within the office retrofit sector.

Introducing Drastic's new Data Protocol: Standardising Multi-Cycle Sustainability Assessments

Systematic gathering of data for sustainability assessments.
Drastic partners Caala, Madaster, VITO and Tecnalia have recently created a unified data protocol to standardise how multi-life cycle data is collected, assessed, and compared across the Demonstrator projects.
In the context of multiple Demonstrators that use varied sustainability key performance indicators (KPIs), data formats, and methodologies, the ability to compare and consolidate results can be significantly hindered. This lack of standardisation can compromise the accuracy and utility of sustainability assessments.
Drastic’s Data Protocol (project deliverable D2.2), developed by Caala with support from the aforementioned partners, addresses this issue via a unified framework for consistent data collection and calculation. It supports Multi-cycle Life Cycle Assessments (MLCA) and Multi-cycle Life Cycle Costing (MLCC) by enabling structured, comparable, and efficient data processing.
Protocol objectives include:
- The streamlining of data collection across Drastic’s Demonstrators
- Ensuring consistency in data formats and methodologies
- Guiding stakeholders in data prioritisation and use
- Promoting awareness of the importance of multi-cycle sustainability assessments
What makes this Data Protocol truly unique is its multi-cycle focus—capturing the value of materials that are reused, recycled, or repurposed across lifecycles, supporting circularity through both simplified and detailed assessments.

Introducing Drastic's Design Guidance and Assessment Framework

Word cloud of the scope of Drastic’s Design Guidance and Assessment Framework.
A recent publication; Drastic’s Design Guidance Framework Based on Multi-cycle Sustainability and Circularity Assessment, is now also available to the public via the Drastic website.
This foundational document was developed by Drastic’s project coordinator, VITO, in collaboration with project partners Tecnalia, WorldGBC, Madaster and Caala.
The framework is designed to support building product developers, architects, real estate developers, and environmental assessors in embedding circularity, sufficiency, and multi-cycle sustainability into their design and assessment processes. It integrates existing frameworks and indicators into a cohesive and practical decision tree.

The Drastic Decision Tree as presented in the Design Guidance and Assessment Framework – showing the general overview of the interlinkages and hierarchy of sufficiency and circularity indicators at multiple scales. (A zoomable version of the decision tree is available on the following Miro board and open for commenting).
The core concepts of the framework are:
- Circularity: maximise material and building value through circular strategies such as reuse, repair, and remanufacturing
- Sufficiency: minimise resource demand while ensuring well-being within planetary boundaries
- Multi-cycle life cycle approach: extending product life by employing cascading circular strategies throughout various life cycle stages
Currently, the framework is being applied across the five Drastic Demonstrator pilot projects, with the aim of reducing whole life carbon emissions and promoting circular practices in the built environment.
The framework will be used to assess the pilot projects on a regular basis, validating their effectiveness in reducing total environmental impacts and total life cycle costs while enhancing levels of circularity.
The framework is designed to support building product developers, architects, real estate developers, and environmental assessors in embedding circularity, sufficiency, and multi-cycle sustainability into their design and assessment processes. It integrates existing frameworks and indicators into a cohesive and practical decision tree.

The video above details the Ice Box Challenge process.
Drastic Norwegian Demonstrator partners, Produktif and Omtre, participated in the Ice Box Challenge last summer in Oslo, Norway, to showcase the benefits of Passive House and circular construction. Their submission for the Ice Box Challenge has now been entered into the prestigious Construction 21 International Green Solution Awards 2024-2025.
For the challenge, two mini-houses were built — one following the Norwegian national code and the other using the energy-efficient Passive House standard. On 19 May 2024, a one-tonne ice block was placed in each house to test insulation performance. After 33 days, the Passive House unit retained 150 kg of ice, while the standard unit’s ice had melted entirely within just 11 days!
This challenge highlighted the potential of circular design, with the Passive House ‘mini-house’ providing a platform for Produktif and Omtre to test their innovations ahead of work beginning on the Norwegian Drastic Demonstrator project.
The Passive House architecture included the Design for Assembly and Disassembly (DFAD) methodology and a ‘C-Joint’ system from Produktif and was clad in repurposed Norwegian barn planks and waste wood harvested, sorted and supplied by Omtre.
The event, co-organised by Produktif, was honored by the presence of Her Royal Highness Princess Astrid of Belgium, who re-opened the mini-houses on June 19 2024, revealing the remarkable results.
Results of the award will be announced in July — follow Drastic's LinkedIn page for the latest updates and news of the announcement!
