Smart & Connective

Our GTB Light
for tertiary buildings

Tertiary buildings, public or private, share similar concerns in terms of energy savings, economies of scale and CSR policy.
These issues are all the more topical, with the rise in energy prices and the implementation of the Tertiary Decree and the BACS Decree.

The advantages for tertiary buildings


1. Fast and significant energy savings

As part of a CSR policy or in order to achieve the objectives set by the Tertiary Decree, tertiary buildings need an effective solution quickly. Smart & Connective will allow you to make up to 50% energy savings upon installation.

2. A turnkey and easy-to-use GTB

Thanks to an extremely quick solution to install (hardware AND software), the GTB Light is ready for use without loss of activity for the operator.
It is then very simple to create energy saving scenarios with your integrator to optimize your installation.

inexpensive solution

3. A simple and inexpensive solution to deploy in an existing and occupied tertiary building

Standard GTBs are important pieces of equipment with a high cost price. There are now new generation BMSs (which are installed at room level instead of acting only on the central system).
With equal performance, Smart & Connective will be the first solution with a cost price between 2 and 15 euros per square meter (depending on the type of building) for energy savings of up to 50%!


4. Eligibility for CEE sheets

The CEE sheets were created by the Ministry of Ecological Transition with the aim of accelerating France's energy transition. The GTB Light Smart & Connective, class A or B, can be financed using CEE sheets, more particularly the BAT-TH-116 sheet.
You will thus be able to conform your tertiary buildings to the decrees and your CSR policy while reducing your bill.

Occupancy rate

5. A system that adapts to its environment

In your tertiary building, you can choose to activate your energy saving scenarios based on the occupancy of your spaces or the external environment and thus act on lighting, air conditioning or heating. Frequency in common areas also allows you to adapt hot/cold production according to real needs.

Predictive Maintenance

6. Predictive maintenance

Thanks to your GTB Light Smart & Connective, you detect devices whose performance is declining in advance, you can identify malfunctions in your devices at a glance to alert your maintenance teams. You can therefore act more quickly and guarantee better longevity for your installations.

Did you know ?

Tertiary buildings of more than 1,000m2 are subject to the Tertiary Decree which regulates energy saving obligations over the next 30 years. The first deadline of September 30, 2022 requires building owners or operators to declare a reference year on the OPERAT platform, which will then serve as a basis for initiating a strategy to reduce energy consumption.

Buildings with an air conditioning or heating system with a nominal power greater than 290 kW (this is generally the same type of buildings subject to the Tertiary Decree), are subject to the BACS Decree: Building Automation and Control Systems. This decree was put in place to help tertiary buildings achieve the objectives set by the Tertiary Decree. In fact, by installing a class A or B BMS, the building is automatically more efficient and makes significant energy savings.

The threshold has been revised to address buildings with a power of 70 kW by 2027.

Case study of offices and tertiary buildings


Martine is CEO of a communications company whose 50 employees work in a modern building in the city center. The glass roof of its open space gives character to the building but in summer the temperature rises quickly and its air conditioning runs at full speed, sometimes even all night. Thanks to its Smart & Connective solution, it can decide that the blackout blinds are automatically lowered when the temperature exceeds 23° and that the air conditioning turns on to maintain a temperature between 22° and 24°.



Élodie is the owner and operator of a hotel subject to tertiary and BACS decrees. In order to comply with regulations while maintaining an optimal level of comfort for its customers and employees, it installed the GTB Light Smart & Connective in common areas and in each room of its establishment. This allows it to optimize hot/cold production according to the attendance rate in catering areas or conference rooms, for example.
It can also create (with its integrator) energy saving scenarios in rooms by limiting set temperatures or by automating the shutdown of air conditioning when a window is open.

School buildings

Jean-Marc is the principal of a high school with 350 students. To save energy, he manages the time slots of his lighting and heating in an automated manner because he realized that certain rooms remained lit all night or that others were too heated and required the teachers to open the window to restore the correct temperature. Without changing his heaters and with these simple adjustments, he noticed a drop in electricity consumption of almost 30% from the first month!
In addition, he installed air quality sensors which allow him to be alerted in the event of a need for ventilation or the automatic initiation of a ventilation cycle. A real plus for the health of students and teachers!
