Energelio

What Energelio does

Energelio (SARL ENERGELIO) is a Lille-based French engineering consultancy (bureau d'études) founded in 2005 that specializes in passive building design and energy-efficient construction for new builds and renovations. The firm operates as a sub-10-person team providing integrated services across the building lifecycle: Conception Globale (integrated energy design embedded in architectural conception), Calculs Énergétiques (PHPP energy balance, 2D/3D finite element thermal bridge calculations per NF EN 10211, dynamic thermal simulation, fenestration performance), Concept Passif (passive methodology), Prise de Mesure (infiltrometry/blower-door testing, thermography, ventilation flow measurement, hygrothermal analysis), and Réhabilitation (EnerPHit/retrofit). Add-on services include AMO for certification, commissioning, M&E (fluides) engineering, and Energy Performance Contracting (CPE).

The company monetizes via professional services contracts billed per project, with fees determined by scope, size, and complexity (not publicly disclosed). Its go-to-market is enterprise field sales through direct commission or competitive tender, embedded in project teams alongside architects, general contractors, and other consultancies. Customer segments span social housing operators (Vilogia, Groupe SNI), municipalities and departmental councils (Préfecture de la Somme, Conseil Départemental du Val de Marne, Paris Terres d'Envol, Ville de Loos), healthcare operators (EHPAD projects), educational institutions (schools, colleges, universities), and industrial/real estate clients (Lesaffre HQ, GSE Régions). Projects span residential, tertiary, educational, healthcare, cultural, and hospitality typologies across France and, in at least one case, Great Britain.

Energelio positions itself as the first French engineering consultancy certified in passive building design and has accumulated first-of-kind credentials including the first PassivHaus Premium project in France (CECODIA, 2022), the first passive school restaurant (Loos), and the first passive hotel in France (Le Havre). The firm holds no patents, has no disclosed funding, no parent company, and operates as an independently owned private limited company (SARL) with €50,000 share capital.

Products and services

• Conception Globale (Global Integrated Design) Integrated energy and environmental design service that embeds energy performance and Passive House methodology throughout the architectural design process, from initial conception through execution and commissioning. Targeted at project owners (developers, public bodies, housing operators) seeking certified low-energy or positive-energy buildings.
• Calculs Énergétiques (Energy Calculations) Specialized engineering calculation service covering PHPP energy balance modeling, 2D/3D finite element thermal bridge calculations per NF EN 10211, fenestration thermal performance per NF EN ISO 10077, dynamic thermal simulation (STD), and geothermal probe sizing. Targeted at architects, developers, and project owners requiring certified PassivHaus or BEPOS performance.
• Concept Passif (Passive House Concept) Passive building design methodology service grounded in five principles: thermal insulation, high-performance windows, controlled mechanical ventilation with heat recovery, air tightness, and passive solar orientation. Delivered as design guidance for new construction and renovation projects targeting PassivHaus or EnerPHit certification.
• Prise de Mesure (Performance Measurement) On-site performance measurement service delivering infrared thermography to detect insulation defects, high-precision ventilation flow measurement using ACIN FlowFinder MK2 ballometer, CO2/humidity/IAQ monitoring, and hygrothermal comfort analysis. Used to verify and document achieved building performance against PassivHaus and HQE targets.
• Réhabilitation (Energy Rehabilitation) Energy rehabilitation service for existing buildings, including energy audits, on-site measurements, complete energy design, and renovation programming targeting EnerPHit, low-energy, passive, or positive-energy (BEPOS) outcomes. Targeted at housing operators, public bodies, and private owners retrofitting existing stock.
• Assistance à Maîtrise d'Ouvrage (AMO) Project owner assistance service (AMO) supporting certification delivery across PassivHaus, BEPOS, Effinergie, Minergie, HQE, H&E, PH&E, BREEAM, and LEED. Acts as a technical advisor to the project owner on certification pathways and deliverables.
• Commissioning Technical commissioning service adjusting and verifying HVAC, ventilation, and building systems so that as-built performance matches the designed energy targets. Supports energy performance guarantees and IPMVP-style measurement and verification protocols.
• Maîtrise d'Œuvre - Fluides (M&E Engineering) Mechanical and electrical (fluides) engineering design covering ventilation, heating, domestic hot water, and plumbing systems sized and specified for energy-efficient and passive buildings. Provided as part of project execution.
• Contrat de Performance Énergétique (CPE) Energy performance contracting (CPE) service that guarantees energy savings, with verification through total measurement of building energy performance improvements. Targeted at owners seeking contractual assurance of energy outcomes.
