ALEC Ouest Essonne

What ALEC Ouest Essonne does

ALEC Ouest Essonne (Agence Locale de l'Énergie et du Climat Ouest Essonne) is a French non-profit association (loi 1901) founded in 2011 at the initiative of local authorities to provide free, neutral energy-renovation and climate-transition advisory services across the western Essonne territory. It serves as the operator of the Paris-Saclay Rénnov' single window under a mandate from Agglomération Paris-Saclay, and functions as an espace conseil (advisory space) within the national France Rénnov' network. The agency is a member of the Fédération FLAME, the national federation of 40+ local energy and climate agencies, and is governed by a board comprising elected officials from its three intercommunalities (Communauté Paris-Saclay, CCDH, CCPL) and representatives of ADEME, AREC Île-de-France, and territorial ecosystem actors. Its president is Delphine Person (Palaiseau, CPS) and its director is Sophie Labrousse.

The agency's service offering is organized around three customer poles — individual homeowners, condominiums, and local authorities — plus a fourth stream for businesses (TPE/PME) and a dedicated energy-poverty program. Core products include France Rénnov' and Paris-Saclay Rénnov' advisory services, the Coach Copro condominium platform, the Confortmètre self-diagnostic, the SLIME program for energy poverty, and the AUTODIAG workshop tool, alongside the Négawatt methodology (sobriety, efficiency, renewables). Distribution is hybrid: four physical locations (Orsay/Palaiseau, Briis-sous-Forges, Dourdan) plus phone, video conference, on-site visits, and an online booking platform via Mixeur/DialogWatt. Marketing combines digital content, social media, weekly newsletter, thermal walks, Cafés Rénnover-Malin, Conversations carbone workshops, webinars, and school/community animations.

The business model is public-sector funded and free to end users. Revenue is sourced from the three intercommunalities and institutional partners including ADEME, Région Île-de-France, Département de l'Essonne, and AREC Île-de-France, with program-specific co-funding for initiatives like SLIME and Rénovons Collectif. The agency is statutorily anchored under Article L 211-5-1 of the French Energy Code and operates a 14-employee multidisciplinary team. The addressable market is anchored by ~500,000 residents across 80 communes, 1,659 condominiums (~59,245 housing units, 54% built before 1994) on Paris-Saclay, and a 9.7% energy-poverty rate, against which the agency has supported 114 condominiums (5,800+ housing units) and 29 long-term global renovation projects.
