What ISB (Equans) does

Equans Belgium (legal entities: Equans Services SA./NV. and Equans SA./NV.) is a multi-technical services provider headquartered in Brussels that delivers electrical, HVAC, mechanical, fire protection, automation, and energy-transition services to enterprise clients across buildings, industries, transport infrastructure, and distribution networks. The company is a subsidiary of Bouygues Group and employs more than 9,200 collaborators in Belgium, operating as one of the country's largest employers with approximately 1,000 new hires annually and 75+ years of operational history in multi-technical installations. Service scope spans technical installation projects, multi-year preventive and corrective maintenance contracts, integrated facility management, and decarbonation services (Carbon Shift) including energy performance contracts, BESS, solar, heat networks, cogeneration, e-mobility charging, and industrial waste-heat recovery.

The company's digital arm, Equans Digital, sells an integrated software stack built on three layers: Quantes (data connectivity across BMS, sensors, and operational systems), OptimiZ (AI-based anomaly detection on BMS data with actionable recommendations), and Optiboard (cloud-based visualization dashboard). These are extended by AI capabilities in the form of Digital Twin and Predictive Maintenance, which combine historical and real-time data to forecast failures and simulate industrial assets virtually. Equans Digital also operates OT Cybersecurity services aligned with NIS2 and IEC 62443, including a unique OT Cybersecurity Simulation Lab modeled on the Purdue architecture for risk-free security testing and training.

Equans generates revenue through a mix of professional services (installation, industrial services), subscription/recurring revenue (maintenance contracts, digital subscriptions), and managed services (decarbonation, energy performance contracts). Pricing is quote-based and tied to multi-year contracts with Belgian wage and material index adjustments for domestic work. The company serves enterprise customers through a direct field-sales and strategic-partner model across 18 European countries plus North America, South America, and Oceania, with named reference clients including Belfius, ENGIE, Elia, Infrabel, Brussels Airport, Proximus, AGFA, Fluxys, and Milence.

Core offering

Equans Belgium provides multi-technical installation, maintenance, and digital services to enterprise clients across four verticals: Buildings, Industries, Transport Infrastructure & Mobility, and Distribution Networks. Core offerings include electrical, HVAC, mechanical, fire protection, and automation installations; preventive, corrective, and regulatory maintenance under multi-year service contracts; integrated facility management; and an Equans Digital portfolio (OptimiZ, Optiboard, Quantes, Digital Twin, Predictive Maintenance, OT Cybersecurity) that overlays operational technology with AI-driven optimization.

Product overview

Equans Digital is the digital solutions division of Equans, offering a multi-layered portfolio of AI-powered and data-driven products for buildings, industrial sites, and infrastructure. The core platform consists of three main products: Optimiz (building energy optimization), Optiboard (centralized building dashboard), and Quantes (data connectivity). These are supplemented by AI solutions including Digital Twin for virtual monitoring and Predictive Maintenance for asset management. The portfolio also includes OT Cybersecurity services with an innovative Simulation Lab for industrial environments. The products work together as an integrated ecosystem: Quantes provides data connectivity, Optimiz delivers AI-powered optimization, and Optiboard serves as the unified visualization interface across all building systems.
