What Accenta does

Accenta is a French greentech company founded in 2016 that decarbonizes commercial, public, and tertiary buildings through an integrated stack combining AI-driven building management, geothermal production, and contractual performance guarantees. Its core platform, Effipilot, is a cloud-based continuous-control system classified as Class A GTB under ISO 52120-1 that ingests sensor and meter data and autonomously optimizes HVAC and energy distribution in real time using predictive analytics and anomaly detection; it is described as the only GTB on the French market producing IPMVP-certified opposable consumption data for regulatory reporting. Accenta complements this software layer with proprietary hybrid geostockage technology, co-developed over three years with BRGM, Mines ParisTech, and École Polytechnique, which uses underground thermal storage to deliver heating and cooling at a claimed COP of 6–7.

The company sells exclusively through direct enterprise field sales to large real estate owners, asset managers, municipalities, social housing providers, and developers in France, with no resellers or self-serve channels. Its revenue model is outcome- and subscription-based: Accenta finances 100% of installation under CAPEX-to-OPEX structures or 10-year Contrats de Performance Énergétique (CPE), commits to guaranteed consumption reductions (paying 66% of any shortfall), and is repaid from realized energy savings, supplemented by CEE subsidies and Eco-PTZ financing. With approximately 150 employees, a managed footprint of 10 million m², and 50+ enterprise customers including Airbus, Fnac-Darty, Union Investment, La Poste, Décathlon, Leroy Merlin, and AG2R, Accenta raised approximately €108 million in September 2023 from Eren Groupe and Siloé Infrastructures (Crédit Mutuel), at which point Siloé gained operational control of the company.

Revenue model

1. GTB Piloting / Building Management Services: Ongoing remote piloting and performance management of building energy systems via the Effipilot platform. Customers pay through energy savings (energy-as-a-service) or through contractual performance fees under the CPE model.
2. Geostockage / Heating and Cooling Production Systems: Design, installation, and operation of geothermal and hybrid geostockage heating and cooling systems. Revenue generated through upfront engineering and installation fees, with ongoing operation under performance contracts. Modular financing options available (with or without CAPEX).
3. Energy Performance Contracts (CPE): Long-term (typically 10-year) energy performance contracts where Accenta funds the full system and is repaid from realized energy savings. The customer pays a fee equal to or less than their previous energy expenditure, with Accenta absorbing performance risk.

Core offering

Accenta provides end-to-end building decarbonization services for commercial, tertiary, and public buildings in France, combining an AI-driven building management platform (Effipilot / Class A GTB) with proprietary hybrid geostockage geothermal heating and cooling technology. Offerings are delivered as turnkey projects under long-term Energy Performance Contracts (CPE), where Accenta finances, installs, and operates the systems and is paid from realized energy savings, with contractual performance guarantees backing up to 80% energy consumption reduction and up to 95% CO2 emission reduction.

Product overview

Accenta offers a comprehensive suite of intelligent building decarbonization solutions organized around its core Plateforme de Conduite Continue (Effipilot) AI platform. The portfolio comprises two main service modules: Pilotage Intelligent des Bâtiments (intelligent building control with up to 40% energy savings) and Production Chaud/Froid (geothermal-based hot/cold production with up to 95% CO2 reduction). These are powered by proprietary Géostockage Hybridé technology and delivered through complementary offerings including the Accenta Box hardware for retrofit deployment, the CPE contractual framework for financing and performance guarantees, and the Optimiser solution for active efficiency without construction. The ecosystem integrates AI-driven automation, predictive analytics, and continuous monitoring to deliver end-to-end building energy optimization.
