What Aveltys does

Aveltys is a French specialist in performance-based building operations and energy management for tertiary (commercial) real estate. Founded as a subsidiary of the ALTYN Group, the company serves building owners, asset managers, developers, and tenants across France through an integrated service portfolio spanning four pillars: commissioning and retro-commissioning, fine-tuning of HVAC and technical installations, ongoing energy management via dedicated Energy Managers, and guaranteed-performance exploitation contracts. Its technical foundation combines digital building management systems (GTB/BACS) with its proprietary Lab AVELTYS platform for real-time performance monitoring, anomaly detection, and compliance reporting under the French Décret Tertiaire regulatory regime.

Aveltys delivers services through a "binome" model pairing an Energy Manager with a Responsable d'Exploitation at each client site, providing continuity from design-phase commissioning through to multi-year operational contracts. Its distinctive commercial proposition is the Garantie de Charges Locatives—a fixed annual charge package for tenants backed by a 50/50 savings-sharing mechanism with the building owner, where Aveltys absorbs any cost overruns. The company holds an EcoVadis Gold Medal (76/100, top 5%) and reports outcomes such as a 19.2% energy reduction (230 MWh) for COLAS in 2023, nearly double target. Revenue is generated through managed services contracts, professional services fees, and recurring energy management retainers, with multi-year contract terms aligned to lease durations. Notable enterprise clients include La Française Real Estate Managers, AXA, AEW, COLAS, and public entities such as Ville de Bussy-Saint-Georges and Agence de l'Eau Artois-Picardie.

The go-to-market is exclusively direct enterprise sales, targeting property owners, asset managers, developers, and tenants in the French tertiary market, with no self-serve, channel, or marketplace distribution. Demand generation relies on content marketing (blog, downloadable guides on Décret Tertiaire), LinkedIn, email newsletters, MIPIM and industry events, and joint webinars with ALTYN Group sister companies. The company is positioned within the broader ALTYN Group ecosystem, enabling cross-subsidiary delivery with engineering (ALTEREA), construction (DUJARDIN, BECIA), project management (ALTERESCO), and digital integration (CYRISEA) partners.

Core offering

Aveltys provides performance-based exploitation of tertiary (commercial) buildings in France, bundling four core service lines: Commissioning, Energy Management, GTB (Building Management System) piloting, and Guaranteed Performance Operations, supported by mass data analysis capabilities. The company operates as a multi-technical operator (multi-technique) that takes responsibility for the energy and operational performance of client buildings under contracts that include performance guarantees, leveraging its Lab AVELTYS digital platform to collect, aggregate, and analyze building data.

Product overview

Aveltys is a performance-oriented building operations company offering an integrated suite of services for tertiary (commercial) buildings. Its core portfolio spans four interconnected pillars: (1) Commissionnement — commissioning and retro-commissioning to ensure systems perform to design targets; (2) Mise au point des installations — technical fine-tuning of HVAC and control systems; (3) Energy Management — continuous energy performance monitoring via GTB/BACS systems and a dedicated Energy Manager; and (4) Exploitation performancielle garantie — guaranteed building operations with optional performance contracts. These services are delivered through named offerings including Garantie de charges locatives (a fixed annual charge guarantee for tenants), AMO Garantie de charges (owner representation for charge guarantees), Contrat de Performance Énergétique (CPE), and the proprietary Lab AVELTYS digital monitoring platform. The overall offer is structured around a binome model pairing an Operations Manager (Responsable d'Exploitation et Services) with an Energy Manager to drive daily performance and compliance with the French Décret Tertiaire regulation.
