Building & Infrastructure

The automation that surrounds us unseen: building management systems, civil structures, data centers. Systems long isolated, now connected — and therefore to be secured — and central to energy efficiency and service continuity.

The main domains

Smart building

BMS / BAS

Building management: HVAC, lighting, access, energy. BACnet, KNX, Modbus protocols. Goal: comfort + energy thrift.

Structures & data centers

Tunnels, bridges, data centers

Structural monitoring, fire safety, and data centers: cooling, uninterruptible power, PUE, availability tiers.

Local energy

District heating, microgrids

District heating, microgrids, EV charging. Demand-side management and renewable integration.

Key challenges

Energy efficiency — buildings account for a major share of consumption. BMS, fine control, demand-side management, certifications (ISO 50001).
Interoperability — multiple protocols (BACnet, KNX, Modbus) to integrate; gateways and unified supervision.
Connected-building cybersecurity — systems once isolated, now on IP: HVAC, access, video become entry points. IEC 62443 applied to buildings.
Fire safety & continuity — tunnel smoke extraction, data-center detection and suppression, uninterruptible power and redundancy (Tier levels).

Key technologies

SCADA Energy efficiency Cybersecurity OT PLC Buses (BACnet, KNX, Modbus)HMI

Standards & references

Add BACnet (ISO 16484-5), KNX (ISO/IEC 14543), the tunnel directive 2004/54/EC, ISO 50001 (energy management) and data-center availability frameworks (Uptime Institute Tier).

Major players

Building management

Siemens (Desigo), Schneider (EcoStruxure), Johnson Controls, Honeywell, ABB.

Data centers

Equinix, Digital Realty, Vertiv, Schneider (APC), Eaton.

Integration & field

Distech Controls, Trend, Sauter, Wago, Beckhoff.

Engineering

Bouygues, Vinci, Eiffage, ENGIE Solutions, Bosch.

Landmark incidents

From tunnel to data center, disasters have shaped fire safety, redundancy and business continuity.

Event	Year	Location	Lesson
Mont Blanc tunnel fire	1999	France / Italy	A truck fire; 39 deaths. Gave rise to the EU directive 2004/54/EC on tunnel safety — ventilation, smoke extraction, refuges.
OVHcloud fire (SBG2)	2021	Strasbourg, France	A data center destroyed by fire, data loss for many customers. A reminder of the criticality of fire safety, backups and business continuity.
