Faced with growing challenges in energy efficiency and regulatory compliance, building management systems (BMS) must evolve to meet the requirements of the energy transition. It is essential to understand this transformation towards Power management, which integrates advanced solutions to optimise the performance of commercial buildings.
Definition and relationship between building management and energy management
Building management monitor technical equipment such as heating, ventilation, air conditioning (HVAC), lighting and security in order to optimise the overall performance of the building in terms of comfort, safety and operation.
Power management complements building management by focusing specifically on energy performance. It uses data collected by monitoring systems to analyse, track and optimise energy consumption, while facilitating regulatory reporting and the implementation of corrective actions.
Regulations and standards is accelerating the growth of this energy approach in commercial buildings by making the installation of energy management systems mandatory. This momentum is reinforced by the adoption of advanced technologies such as predictive analysis and the interoperability of technical systems. Finally, the NF EN ISO 52120-1 standard sets an ambitious framework, with a target of reducing energy consumption by 40% by 2030, without compromising occupant comfort.
Features and technical systems of BMS and Power management solutions
Building management systems monitor HVAC, lighting, security and access control equipment to improve energy efficiency and occupant comfort in buildings.
Building management controls heating, ventilation, air conditioning, lighting and security systems via sensors and actuators connected to a central system. BACnet and Modbus protocols ensure interoperability between these devices to optimise overall operation and reduce operating costs.
Power management incorporate predictive analysis and advanced energy reporting to identify waste and optimise performance.
Interoperability between technical systems is based on standardised protocols such as BACnet and Modbus for exchanging data between heterogeneous equipment in an Power management approach. The use of BIM for Operation facilitates the centralisation of technical and energy data. BIM, or Building Information Modelling, improves coordination between heterogeneous systems for the seamless integration of technical equipment into an energy supervision project.
Regulatory impact and energy benefits of Power management systems
Some of regulations and standards imposes an obligation of means: to equip tertiary buildings with energy regulation, measurement and control devices. Once installed, these systems can remain underutilised or even inactive if they are not integrated into an active performance management approach.
This is precisely the role of Energy Management Systems: to fully exploit the data from these devices to continuously monitor consumption, identify deviations, optimise settings and generate measurable savings. Power management thus transforms a regulatory obligation into an operational lever for energy performance.
By cross-referencing consumption data with performance benchmarks, Power management solutions facilitate regulatory reporting and the identification of savings opportunities.

Optimised energy monitoring delivers a return on investment in 2 to 4 years.
The future of technical SCADA and energy intelligence
Predictive analysis is transforming technical monitoring by providing increased energy anticipation and optimisation capabilities. Monitoring systems are evolving towards solutions capable of detecting potential faults upstream, dynamically adjusting equipment parameters and ensuring greater comfort for occupants. Platforms such as SCADA illustrate this transition by enabling fine-tuned consumption management and reducing downtime through predictive maintenance.
Panorama E2 optimises energy performance by integrating building management, BIM and HVAC data for a unified view. Its advanced reporting, predictive maintenance and interoperability with BACnet protocols facilitate the transition to Power management and respect of Regulations and standards.
Thanks to interoperability and systems such as Panorama E2, energy efficiency and occupant comfort are optimised, transforming commercial buildings into key players in sustainable strategy. An essential development for anticipating future challenges.
