GTB stands for building management system. It's an IT solution that's installed in large buildings , particularly in the industrial and service sectors. This system is used to supervise the equipment installed in a company's buildings. Among the equipment managed by this solution are lighting, heating, air conditioning, ventilation and the opening and closing of blinds.
GTB Class A definition and objectives
This Class A system has a number of specific objectives.
Key features of the A-Class GTB
According to NF EN ISO 52120-1, a Class A BMS is a high-performance building management system.
Class A BMS controls equipment by collecting data from installed sensors. This data is processed to make decisions on the building's energy consumption.
Why aim for Class A? Benefits and impacts
A company installing a BMS must aim for class A for a variety of reasons. A Class A system is ideal for :
- save energy
- improve comfort
- a more ecological and responsible approach
- to ensure the safety of building occupants.
This has a positive impact on a number of aspects that should not be overlooked. We'll take a closer look at the advantages of Class A.
Comparison of BMS classes according to NF EN ISO 52120-1-2022
Other classes also exist. Here's a comparison of the different GTB classes.
Distinctions between classes A, B, C and D
So there's the energy-efficient Class A, but also :
- class B: advanced BMS
- Class C: standard building management systems
- class D: a BMS judged not to be energy-efficient
The impact of class is very important. For the energy performance of a Class A building, experts take into account regular maintenance, energy monitoring, automated energy management and sustainable energy optimization.
For class B BMS, there's the option of room automation and annual energy monitoring.
There is no energy monitoring in a class C BMS. However, it is possible to automate primary installations on a network.
Class D is distinguished by the fact that it is not eligible for the BACS Decree, and no new building can be constructed with this system. Work must be carried out to change or upgrade the existing system.
Performance and evaluation criteria
Class A ensures a control system that takes into account the presence or absence of people in the building in real time, the ambient temperature in which people are present, and the equipment to be managed.
For example, the technical management of Class B buildings does not take into account occupancy-based control systems.
Class D is limited to the on/off functionality of devices, and does not allow optimal management of their energy consumption. In class D, some devices will run 24/7 without being useful.
The higher the class, i.e. close to A, the greater the energy savings for a company.
To give you an idea of the possible comparisons between two classes, going from a class C to a class B guarantees 15% energy savings. Changing the BMS system from a C to an A class, on the other hand, guarantees energy savings of up to 30%, i.e. twice as much.
Implementation and installation of a Class A BMS
To implement a Class A BMS, there are several steps to follow.
Key stages in installing a Class A BMS
It's essential to carry out an energy audit so that the installer can propose the most appropriate BMS solution. In this way, the BMS solution can be adapted to the needs of the company's occupants.
The interface must be correctly chosen so thatit is intuitive and clear to all. The occupants must then be trained by the installers to understand all the system's functionalities and use it properly.
Choice of service provider and selection criteria
To choose the right technicians for your project, don't neglect to request a quote. This will enable you to compare different offers.
For this choice, the installer must have the RGE or Eco-artisan label. This label certifies that the technicians have the right qualifications, and that they are companies authorized to install this type of system. In this case, you may even qualify for an installation bonus. The CEE (a government-sponsored scheme) even grants a financing bonus for installing these technical and IT systems.
The technology installed must comply with regulations, in particular the BACS decree.

Specific benefits of GTB A-Class
Once you've familiarized yourself with the advantages of Class A BMS, you'll understand the benefits of this type of installation.
Energy optimization and cost reduction
With such a system, temperature regulation of heating, air-conditioning, ventilation, lighting and so on is automatic, depending on the presence or absence of people in the building. In this way, energy consumption is kept under control to ensure that no energy is wasted.
This reasoned consumption ensures lower costs, as you consume less energy.
Improving occupant comfort and safety
Air quality, temperature, everything is regulated to guarantee optimum comfort for users. If the company has offices in this building, greater comfort, thanks in particular to a pleasant temperature, ensures greater productivity.
In terms of security, this system can detect gas leaks, fire or the presence of unknown persons in the building. Alarms are automatically triggered to ensure personal safety and security.
A-Class GTB and sustainable development
Heating systems, air conditioning, lighting, you name it, the BMS manages the power and operation of all these devices. In this way, the BMS system has an impact on consumption, and therefore on the conservation of resources.
A-Class GTB's impact on the ecological footprint
The consumption of this type of equipment is regulated, ensuring an improvement in the energy class of buildings. As a result, by regulating technical systems, energy resources are preserved.
The tertiary sector decree for businesses takes ecological impact into account. The tertiary decree is a regulation that can be complied with thanks to class A GTB .
A-Class GTB and CSR strategies
These functions ensure that companies meet their CSR (Corporate Social Responsibility) objectives. It's essential today! Class A BMS ensures management that transforms buildings to improve their energy efficiency.
These ecological objectives are directly linked to a company's CSR policy, which calls for better management of its heating, air-conditioning and other energy systems. By taking these steps and regulating its energy resources, the company can improve its CSR strategy and meet the criteria of the tertiary sector decree, if it is concerned.
