Dorémi Rénovation

What Dorémi Rénovation does

Dorémi Rénovation, legally DOREMI SAS, is a French Société Coopérative d'Intérêt Collectif (SCIC) agréée Entreprise Solidaire d'Utilité Sociale (ESUS), headquartered in Alixan (Valence) and operating since 2017 as a spin-out of the Association négaWatt. The company delivers end-to-end, high-performance energy renovation services for individual houses in France, covering six integrated work packages — wall, roof and floor insulation, windows, ventilation and heating — managed under a single chef de projet from diagnostic through air-tightness testing and post-work performance verification. Its core methodology is codified in the proprietary Référentiel technique Dorémi and operationalized through the MonSuiviRéno digital application, which connects territorial animators, RGE-certified artisans trained in a proprietary 57-hour program, and households across the project lifecycle.

The business model combines professional-services revenue from project coordination and pilotage fees on renovation contracts, revenue from artisan training programs, and public funding streams including France Relance subsidies, ADEME co-funding, CEE certificates, MaPrimeRénov' and the Facilaréno program with the Ministère de la Transition Écologique. Renovation projects are quoted at roughly €800-900 per m² and incorporate financial-aid optimization (MaPrimeRénov', eco-PTZ up to €50,000, local aids). Go-to-market is sales-led through three regional agencies (Lyon, Paris, Rennes), inbound leads generated by the SimulRénov open-data simulator, blog, MOOC, podcast and YouTube channel, and a partner channel of 50+ local authorities that funnel households to Dorémi.

Dorémi has renovated more than 400 houses cumulatively (~100 in 2025) and reports measured post-renovation energy consumption of 34 kWh/m²/year, below the BBC label threshold of 50 kWh/m²/year. The company originated from négaWatt, was attached to renewable-energy cooperative Enercoop as a shareholder in summer 2026, and operates under Vincent Legrand (Président) and Arthur Brac de la Perrière (Directeur Général).

Core offering

Dorémi provides end-to-end, project-managed high-performance energy renovation services for individual houses, covering six work packages — wall insulation (interior and exterior), roof and attic insulation, floor/slab insulation, windows, double-flow ventilation, and heating systems (heat pumps, wood stoves). A dedicated chef de projet coordinates diagnosis, certified RGE artisans, financing plan assembly (MaPrimeRénov', CEE, éco-PTZ, local aids) and quality control, with mid-construction air tightness testing to guarantee measurable post-renovation performance (average 34 kWh/m²/year, equivalent to BBC label or better).

Product overview

Dorémi offers a comprehensive energy renovation service for individual houses, structured as an end-to-end accompaniment model. The core offering is the 'Rénovation énergétique globale' which manages all 6 work categories (insulation of walls/roof/floors, windows, ventilation, heating) from initial diagnosis through completion with quality testing. This is complemented by digital tools including SimulRenov for project simulation and MonSuiviRéno for renovation tracking, plus educational resources such as the MOOC 'Ma rénovation pas à pas', the 'Rénovez-moi' podcast, and an expert blog. The R&D function 'Le Lab' Dorémi drives continuous innovation in renovation methodology.
