Goal & context

Carbon Saver's founder won the Prix Margaret, under the patronage of the President of the French Republic and in partnership with Banque des Territoires, the public investment arm of France's Caisse des Dépôts. The award opened a two-year residency inside Banque des Territoires.
The goal: put eco-design to work for public building retrofits, with a solution that fits public budgets and technical constraints. The proving ground: EduRénov, Banque des Territoires' school retrofit program.

Through this residency, Carbon Saver was able to:


    Work side by side with Banque des Territoires teams for two years

    Test the platform against the real constraints of school buildings: public budgets, schedules, existing stock

    Design a solution dedicated to EduRénov for school retrofits

    Compare several retrofit scenarios in real time with the BIM engine

Results & impact


    Carbon Saver now offers a solution built for school retrofits, proven alongside a major public funder.


    Eco-design indicators help steer retrofit choices so that every dollar invested does more.


    A method that carries over to other public buildings: town halls, facilities, social housing.
