• The laureates of the fourth call for solutions have been chosen

    At the winners' unveiling event held on June 22, the final jury and public votes chose two winners, F-Reg and UpFactor. Two solutions were chosen as favorites: Faiseurs de Terres and Terra Innova.

    Themes of the fourth call for solutions

     

    Adaptation of infrastructures and buildings to their territories

     

    Today's buildings must conform to the changes in the territories so as not to radically transform their appearance but rather to adapt to environmental constraints and landscapes. It is now a question of thinking of buildings and engineering structures not only as respecting biodiversity but also as places that are conducive to the development of terrestrial and aquatic ecosystems.

    From the subsoil with the water table to air quality, via the foundations and soils, whose regeneration is a major challenge, the buildings of tomorrow will have to preserve life. It is also essential to increase the resilience of buildings to all types of risks and unpredictable phenomena linked to the territory and the climate. In this perspective, innovative solutions and management and measurement tools must be sought and integrated into future projects in order to shape buildings, whether new or old, in the image of their territory.

     

     

    6 main themes have been chosen by SEKOYA partners for this fourth call for solutions:

    1. Soils, biodiversity and landscapes: preserve and regenerate soils to promote the reversibility of uses (meadow, farm, watering place, etc.).
    2. Preservation of groundwater: preserving life and ecosystem services associated with groundwater and preserving water resources.
    3. Raising buildings and structures: limiting the land area, preserving biodiversity and adapting to climatic events, such as flooding.
    4. Adapting to extreme weather events: cope with climatic events, such as heat waves, fires and floods.
    5. Fragility of foundations and engineering structures: better anticipation and monitoring of the impacts of climate change on buildings, particularly on foundations and engineering structures.
    6. Methods and tools to improve knowledge of an area: improving knowledge of an area through data management and optimisation (GIS, environmental analysis tools).

    HOW DOES SEKOYA WORK?

    The Carbon & Climate platform seeks to identify and qualify innovative, sustainable and low-carbon solutions through an online application process. Eiffage and its partners will qualify the most effective solutions (via a carbon footprint statement and a life cycle analysis) with a potential to contribute to a more frugal construction.

    The platform is technically operated and hosted by the Impulse Labs accelerator, an actor experienced in identifying innovative solutions since its creation.

    FOCUS ON CARBON & CLIMATE ISSUES:

    New Forms of Mobility

     

    • Optimise mobility fluidity in congested urban areas (signage, digital control, adaptation to real flows...).
    • Enhance the attractiveness and intuitive understanding of public transportation offers for all types of users.
    • Promote low-carbon forms of mobility and urban land use.
     
     

    Biodiversity and Ecological Engineering

    • Reintegrate nature into cities as a source of ecosystem services: creation of freshness isles, urban agriculture and short circuits, use of CO2 for agricultural purposes, etc.
    • Develop solutions to restore degraded natural areas (soil stabilisation, water infiltration, soil decontamination by plants, renaturalisation of mineral areas, etc.).
    • Tool to evaluate the quantities of stored biogenic carbon.

    Low-carbon Design and Implementation

    • Systemise the use of low-carbon materials.
    • Propose an efficient, biosourced insulation for new and renovated buildings.
    • Develop industrialised solutions for energetic renovation.
    • Design buildings with scalable uses and without structural costs.
     
     
     

    Methods and Tools

     

    • Absorb CO2 in cities and rural areas by reintroducing green spaces into our projects.

    Circular Economy

     

    • Develop rapid resource diagnostic solutions designed used before existing buildings' demolition.
    • Develop physical and/or virtual exchange systems between supply and demand for land, materials, equipment, etc.
    • Develop solutions for on-site reuse of concrete and aggregates in construction, infrastructure, treatment of deconstructed materials before reuse, etc.

    Renewable Energies and Energetic Performance​

    • Propose upstream diagnostic systems for the use of local renewable energies.
    • Develop any energy-saving solution.
    • Develop new solutions for renewable energy production and recovery.
    • CO2 capture processes.
