SEKOYA's sixth call for low-carbon & climate solutions is now closed. Thank you to everyone who submitted their applications. The submissions will be carefully reviewed very soon.

    The themes of the sixth call for solutions


    Data in service of environmental performance and sobriety at the core of construction solutions


    Aware of their impact on the environment as well as the opportunities presented by the ecological transition, construction sector stakeholders are mobilizing to undertake coordinated and innovative action to meet current environmental challenges.


    In this context, data exploitation emerges as a strategic lever. The sector now has access to a vast amount of data collected over recent years but must capitalize on and structure the management and valorization of this data. The human element remains central, treating data as a powerful aid in decision-making for use cases such as: modeling and predicting the impacts of construction projects on surrounding biodiversity, optimizing building design, improving resource management during the construction phase, and throughout the buildings' lifecycle. Although these data require special attention to be fully understood and leveraged, the opportunities they present are therefore promising.


    However, the transition to a more efficient use of data cannot be separated from a broader dynamic of frugality and environmental responsibility. Adopting resource and energy frugal practices becomes not just necessary but vital for ensuring a viable future. Implementing measures that allow for the adoption of lightweight and modular construction methods to minimize construction waste, improving buildings' thermal insulation, and adopting sustainable soil management techniques are all solutions that contribute to reducing the environmental impact of the construction sector.

    The two themes chosen this year are :


    1. Data in service of environmental performance 

    Environmental performance addresses biodiversity, climate, and resources challenges as well as cross-cutting data aggregation issues such as CSR compliance, risk forecasting, impact assessments, identification of sustainable business models, urban planning, etc.


    2. Sobriety at the core of construction solutions 

    • Material sobriety: materials, products, and construction processes (modular, reversible, changes in use, repairable) to minimize construction waste, reuse
    • Energy sobriety: materials, energy efficiency, thermal regulation of buildings
    • Land sobriety: rehabilitation of industrial wastelands, revitalization of neighborhoods
    • Resource sobriety (water, soil, etc.): water revalorization, soil preservation


    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.
