What So.co.ner does

So.co.ner (legal name: SOCONER, structured as a Société par Actions Simplifiée) is a French building engineering consultancy founded in 2011 and headquartered in Toulouse, France, with additional offices in Paris (140 bis Rue de Rennes, 75006) and Bordeaux (Spaces Bordeaux Euratlantique). The firm delivers specialized engineering services across four interconnected disciplines: building fluid systems (HVAC, heating, ventilation, plumbing, geothermal, fire safety, and electrical); environmental and thermal engineering (dynamic thermal simulation, energy studies, life-cycle cost analysis, and certification support); operation and maintenance advisory (AMO); and design and construction oversight (MOE). Its client base spans French real estate developers, social housing operators, public authorities, architects, general contractors, industrial tenants, and healthcare providers undertaking new construction or rehabilitation across office, residential, healthcare, industrial, cultural, sports, and defense buildings.

The company's technology stack centers on Building Information Modeling (BIM), which is used for fluid-systems design, clash detection, and cross-discipline coordination across building trades. Supplementary technical capabilities include dynamic thermal simulation (STD) for energy-performance forecasting, digital twin creation for building energy prediction and operational optimization, and the proprietary Wandeed quality management platform — a collaborative tool that enforces ISO 9001-compliant validation workflows across all mission types, project phases, and deliverables. Soconer holds OPQIBI qualifications with RGE mention across sustainable building engineering, complex HVAC engineering, thermal regulation studies for collective housing and tertiary buildings, and geothermal installations, and has been a certified BDO (Bâtiments Durables Occitanie) accompagnateur since 2020. The firm also supports client projects through HQE, BREEAM, BBCA, NF Habitat HQE, and Promotelec certifications.

Soconer operates a professional services revenue model with project-specific fees based on scope, complexity, and building type; pricing is not publicly disclosed. Its go-to-market motion is sales-led and relationship-driven: direct engagement with project owners (maîtres d'ouvrage), architects, and construction firms, supplemented by a project portfolio website, regional partnership network, and competitive bidding on both public and private tenders. Engagement is delivered through MOE (design and construction oversight) and AMO (client advisory and asset management) frameworks across the full building lifecycle from conception through operation. The firm has ~22 employees across its three offices, a SAS share capital of €13,890, and no disclosed external investors or parent company.

Core offering

So.co.ner is a building engineering consultancy that designs fluid systems (HVAC, heating, ventilation, plumbing, geothermal, fire safety, electrical), performs environmental and thermal engineering (dynamic thermal simulation, energy studies, certification support), and delivers operation and maintenance advisory services (technical audits, maintenance strategy, contract drafting, performance monitoring). Engagements are delivered as Maîtrise d'Œuvre (MOE) or Assistance à Maîtrise d'Ouvrage (AMO) missions for new and rehabilitated buildings across commercial, residential, cultural, industrial, healthcare, and sports segments.

Product overview

Soconer is a building engineering consultancy operating as a unified service offering across three interconnected disciplines: Fluides (fluid systems engineering covering HVAC, heating, ventilation, plumbing, geothermal, fire safety, and electrical), Ingénierie Environnementale et Thermique (environmental and thermal engineering with dynamic simulation, energy studies, and certification support), and Ingénierie Exploitation Maintenance (operations and maintenance advisory). These core services are delivered through two engagement models — Maitrise d'Œuvre (MOE) for design and construction oversight and Assistance à Maitrise d'Ouvrage (AMO) for client advisory and asset management. The company also offers BIM execution planning and maintains internal quality management via Wandeed. Soconer operates from three offices in Toulouse (headquarters), Paris, and Bordeaux.

• Burgeap: French engineering consultancy with deep environmental, fluid-systems and energy expertise serving building, infrastructure and industrial clients. Directly comparable in technical disciplines (environmental and fluid engineering) although heavier on environmental/geotechnical niches versus Soconer's building-services orientation.
• Ginger Groupe: French engineering group specializing in building engineering, environmental studies, fluid systems and AMO services. Closely comparable to Soconer across fluid/thermal/environmental/AMO service lines and French customer base, while operating at a larger and more diversified scale.
• BTP Consultants: French building project management and engineering consultancy providing MOE, AMO and technical consultancy on residential, commercial and public buildings. Directly comparable to Soconer in MOE/AMO service mix and French building-project customer base, typically at a modestly larger scale.
• Alterea: French engineering consultancy focused on building energy efficiency, fluid systems design, thermal studies and AMO services for residential, commercial and public-sector clients. Directly comparable to Soconer in fluid/thermal/AMO offering, with similar French regional client base.
• Elithis: French building engineering consultancy with a strong low-carbon and energy-positive building practice covering fluid systems, thermal simulation, and environmental certification (HQE, BREEAM, BBCA). Highly comparable to Soconer in service mix and sustainability positioning, with overlapping regional presence.

Broad incumbents

• Artelia: Major international French-headquartered engineering consultancy covering building, infrastructure, industry and environmental projects, including MEP, energy and AMO services.
