What Bielec Ecla does

Bielec Ecla (legal name Bielec Ecla Ingénierie, SIRET 50045068900038) is an independent French electrical engineering consultancy founded in 1978 and headquartered in Mont-Saint-Aignan, near Rouen in Normandy. The firm operates as a traditional bureau d'études techniques offering four integrated service lines: electrical engineering studies for strong and weak currents (including power distribution, EV charging, IT cabling, and lightning protection); architectural and functional lighting design; fire safety system coordination (SSI/CSSI) across categories A through E; and photovoltaic system design, simulation, and project management. Supporting services include full maîtrise d'œuvre project management, assistance à maîtrise d'ouvrage (AMO) advisory, and Energy Savings Certificates (CEE) compliant lighting sizing studies. Selected reference projects include the Université de Rouen Normandie library (€1.7M Bielec lot), CHU Rouen long-term care unit (€1.16M), a 237-room CROUS student residence, the SEM ASER 1.8 MWc Halles de Normandie solarization, and the BEAC central bank headquarters in Yaoundé, Cameroon (€11.3M Bielec lot).

The firm's technology stack centers on BIM-based design workflows using Autodesk Revit MEP for 3D electrical system design, technical coordination, and iterative optimization during study phases, supplemented by specialized simulation tools Archelios Pro and Enolab for photovoltaic feasibility and performance modeling, and EVO and DIALUX for lighting design. Bielec Ecla maintains a broad portfolio of OPQIBI and OPQIBI RGE qualifications (covering lighting studies, photovoltaic studies and project management, standard and complex electrical installations, SSI coordination categories A-E, and IT/comms systems), which serve as gating credentials for regulated French public-sector tenders. The firm is also a member of Normandie Énergies, ENERPLAN, the Association Française de l'Éclairage, and the Label 1Action1Arbre sustainability initiative (joined 2025), and sources 100% of its office electricity from renewable energy cooperative Enercoop.

Bielec Ecla operates as a B2B professional services consultancy generating revenue through billable engineering studies, design, and project management on a per-engagement, quote-based pricing model. The go-to-market is direct enterprise field sales: clients initiate contact via the bielec.fr website form or direct phone/email and are supported by dedicated expert teams throughout the project lifecycle. The firm serves four primary customer segments: architects and design firms requiring BIM-based engineering support; public institutions and government (the largest segment by reference project visibility, spanning universities, hospitals, schools, social housing, and government buildings); property developers and construction companies; and, secondarily, industrial and commercial operators requiring photovoltaic and energy efficiency studies. The firm is described as a family-owned independent engineering bureau with no external investors or parent company.

Core offering

Bielec Ecla Ingénierie is an independent French engineering bureau (bureau d'études techniques) providing electrical engineering studies for strong and weak currents, architectural and functional lighting design, fire safety system (SSI) coordination, and photovoltaic system design and simulation. The firm supports construction, renovation, restructuring, and reconstruction projects for public institutions, architects, property developers, and industrial clients, using BIM 3D design and specialized simulation software across the project lifecycle from feasibility study through construction supervision.

Product overview

Bielec Ecla is an independent engineering bureau (bureau d'études techniques) founded in 1978, offering a unified portfolio of electrical engineering services. The core offering centers on four integrated service lines: electricity studies (strong and weak currents), architectural lighting design, fire safety system coordination (SSI), and photovoltaic system engineering. Supporting these core services are BIM 3D design capabilities, complete project management (maîtrise d'œuvre), client advisory (AMO), and CEE-compliant lighting sizing studies. The company operates as a traditional engineering consultancy rather than a software product company, providing comprehensive project support from design through construction supervision.
