BMS (Building Management Systems)

A Building Management System (BMS) is a computing system for two-way communication with a building's technical equipment. It enables the monitoring and control of equipment such as air conditioning, heating, ventilation, lighting, and energy supply. BMS significantly improves the performance of buildings by centralising and automating operations, making them intelligent and responsive.

Carbon dioxide (CO2)

Carbon dioxide (CO2) is an odourless, colourless inert, and non-toxic gas. It is predominant in the earth's atmosphere and is an essential component of the carbon cycle. The building and public works (BTP) sector, which is crucial for our infrastructures, is also a major source of CO2 emissions, accounting for around 25% of emissions in France.

EPC (Energy Performance Contract)

An Energy Performance Contract (EPC) is an agreement between a client (public or private) and a company to improve the energy performance of one or more buildings. It guarantees a level of energy performance to be achieved over a predefined period concerning a specific situation, thus providing a contractual basis for energy improvements.

Electrical sub-meter

The electrical sub-meter, also known as a sub-division meter, is a device associated with the general electrical meter.

While the main meter provides an overall view of a building's electricity consumption, the electricity sub-meter precisely records the electricity consumed by specific areas and uses within the building.

Energy efficiency

Energy efficiency refers to the ability of a system, whether an appliance, a building or an industrial process, to minimise its energy consumption while maintaining the same level of service. The objective of energy efficiency is two-fold: to reduce the costs associated with energy consumption and the environmental impact.
