What is BMS?

The BMS (Building Management System) is a centralised system used to monitor, control, and optimise all of a building’s technical equipment. It collects, processes, and analyses data from various systems such as heating, ventilation, and air conditioning (HVAC), lighting, energy meters, electrical equipment, and security systems.

Through a single platform, BMS provides a comprehensive, real-time overview of the building’s operations. It enables operators, managers, and maintenance personnel to monitor performance, detect anomalies, automate certain actions, and improve the energy efficiency of the systems.

In practical terms, the BMS centralises information from various technical systems, analyses their operational status, and enables remote control of the systems. It facilitates the management of energy consumption, the planning of maintenance operations, the monitoring of occupant comfort, and compliance with environmental performance goals.

Why use a BMS?

BMS is a key tool for improving the energy, operational, and environmental performance of buildings.

At Equans Digital, we design open and interoperable BMS architectures capable of connecting all of a building’s technical systems. This approach enables the centralisation of data, the automation of operational tasks, and the provision of real-time insights essential for decision-making. From audit to operations, our experts support building managers in sustainably optimising their energy and operational performance.

• Centralised control of systems through a unified view of all the building’s technical systems.

• Reduced energy consumption through automatic optimisation of heating, air conditioning, lighting, and other energy-intensive systems.

• Improved occupant comfort through more precise control of temperature, air quality, and lighting.

• Rapid detection of anomalies to identify operational deviations before they affect the building’s performance.

• Optimisation of maintenance through improved visibility into the condition of equipment and the analysis of operational data.

• Reduced operating costs by limiting unnecessary energy consumption and improving system availability.

• Monitoring of energy performance indicators to measure results and guide improvement plans.

• Contribution to decarbonisation goals by reducing the energy footprint of buildings and facilitating the implementation of energy-efficiency strategies.

• Enhanced regulatory compliance, particularly under the BACS Decree, the Tertiary Sector Decree, and various obligations related to building energy performance.

Concrete examples of BMS usage

• Smart control of heating and air conditioning: automatic adjustment of temperature setpoints based on occupancy schedules, weather conditions, or actual building usage.

• Optimised lighting management: automatic shutoff of lights in unoccupied areas and adjustment of light intensity based on available natural light.

• Energy consumption monitoring: real-time tracking of electricity, gas, water, and heat consumption to identify deviations and opportunities for savings.

• Proactive fault detection: Automatic identification of equipment exhibiting degraded performance or abnormal behavior.

• Multi-site management: Centralised oversight of multiple buildings from a single platform to standardise practices and facilitate the management of the real estate portfolio.

• Occupant comfort monitoring: monitoring of environmental parameters such as temperature, humidity, and air quality to improve the user experience.

• Support for environmental initiatives: generation of metrics and reports to facilitate tracking of CSR goals and energy consumption reduction plans.

In summary

The BMS is a strategic tool for monitoring and optimising a building’s technical systems from a centralised platform. By improving energy efficiency, occupant comfort, maintenance, and operational management, BMS contributes to the creation of smarter, more sustainable, and higher-performing buildings. Today, it is a key component of building digitization and energy transition strategies.
