What ENEZEN does

ENEZEN is a French independent building automation and energy management integrator founded in 2018 within Groupe GECEHA and operating independently since 2023. Headquartered in Boissy Saint Léger in the Île-de-France region, the company deploys Building Management Systems (GTB/GTC) that integrate HVAC, lighting, blinds, and ventilation equipment using standard protocols (BACnet, Modbus, KNX) and wireless LoRaWAN solutions tailored to tertiary-sector renovation projects. Its core technical stack centers on Siemens platforms (Desigo CC, Desigo Optic, Energy Data Explorer, Connect Box) alongside PCVue, complemented by multi-fluid metering hardware (electricity, gas, water, heat) for real-time consumption monitoring.

The company's revenue model blends one-time project-based integration work with recurring elements from supervision software subscriptions, multi-fluid metering deployments, and ongoing energy consulting. Pricing is custom and contract-based, with no public tiers, and projects typically extend on multi-year terms. GTM is sales-led, combining direct field sales with a web-based Energy Savings Simulator that serves as a top-of-funnel lead generator, supported by content marketing (blog, Q'WATT DE NEUF podcast) and industry memberships in FFB, EBI 77, and Le Coq Vert.

Customer segments are diversified across tertiary buildings (offices, commercial properties), schools and educational establishments, local authorities, and property managers/syndics. Strategic positioning as an "Assistant Maître d'Ouvrage Décarbonation" leverages partnerships with Siemens (since 2022) and former parent Groupe GECEHA to bundle technical integration with regulatory compliance expertise around the Décret Tertiaire and Décret BACS mandates. The team of 7 employees limits scale but concentrates competency in a regulatory-driven niche market.
