The GTB Light revolutionizes
renovation of tertiary buildings

Technical Building Management is a formidable tool against energy waste. However, the solutions offered are often complex to install and use.

In fact, it is estimated that 70% of installed GTBs are poorly or not used!

GTB

The Light Smart & Connective GTB can be added to an existing GTB or create a new ecosystem for unequipped buildings.

What is a GTB?

In the classic sense of the term, Technical Building Management is a digital tool that helps limit energy waste in a tertiary building and thus improve energy performance.

GTB: How does it work?

GTB automates the uses of energy-consuming devices in buildings, such as air conditioning, heating, ventilation or lighting. The building is thus connected AND intelligent, which means that it can adapt to the habits of the occupants in order to optimize energy consumption as much as possible.

For example, if the use of the building is exceptionally low (due to seasonality or an event), GTB will be able to adapt the production of hot and cold.

Buildings

Monitoring and management of the building

Supervising your building means knowing at any given moment what it consumes and the stations to monitor. Depending on the needs, it is possible to know if a room is occupied, if a window is open/closed, if the air quality in a classroom is good, or the temperature of the offices. All this information is visible on a hypervision portal (we can generally group several buildings on the same screen). This makes building information clear and readable for better operation.

A Technical Building Management system not only allows the reporting of data on consumption (temperatures, air quality, opening status of doors/windows, humidity level, etc.), but above all it is capable of intelligent management energy-consuming devices in order to respect pre-established scenarios.

For example: “I want my offices to always be at 22°C regardless of the outside temperature. »
The system will not only tell me that the temperature is too high or too low, it will also automatically adjust the air conditioning or heating to reach the requested 22°C.

GTB in building maintenance

Properly used, BMS can help extend the lifespan of equipment, in particular by providing indications of maintenance, upkeep, breakdowns or declines in performance.

Thus, if a device is detected less efficient or with abnormal consumption, a maintenance alert will be sent in order to anticipate a possible breakdown and avoid unnecessary overconsumption. We then speak of predictive maintenance.

The 4 classes
performance of a GTB

The European standard NF EN ISO 52120-1 “Energy performance of buildings – Contribution of the automation of regulation and technical management of buildings”, governs the use and performance of GTBs.
In order to determine the energy savings achievable through the installation of a BMS in a building, the standard defines 4 performance classes of a BMS.

– Class A: regulation and BMS with high energy performance;
– Class B: regulation and advanced GTB;
– Class C: standard regulation and GTB, usually taken as a reference;
– Class D: regulation and BMS limited to basic functionalities such as on/off or manually controlled. There we will find buildings that have not been renovated, are equipped with old equipment or have been the subject of limited investments.

The limits of “classic” GTB

X

BMS installed without end users knowing how to operate them (complexity, lack of training and documentation).

X

GTBs used for control but rarely for piloting (poor operation of the system).

It is estimated that 70% of installed GTBs are poorly used or not used at all!

On the other hand, classic GTBs are generally installed during the construction of a building or during major renovations because they require complex technical works and installations. The power and complexity of these solutions also explain the often dissuasive costs per m2.

The advantages of the GTB Light

As an alternative to powerful, installation-heavy GTBs, there are now so-called lightweight GTBs, based on connected object technology, which offer several advantages:

These GTBs, such as the Light Smart & Connective GTB, are perfect for the renovation of tertiary buildings. This represents 983 million m2 in France and 800 million m2 which are subject to the Tertiary and BACS decrees.

Today, only 7% of tertiary buildings are equipped with a BMS.

The Light Smart & Connective GTB can be added to an existing GTB or create a new ecosystem for unequipped buildings.

Worksite

No work
required.

Chronometre

Quick setup
and simplified for the integrator – no code.

simplified handling

Simplified handling by the end user and multi-site vision.

Smart Building

Suitable for existing tertiary buildings such as offices, hotels, public buildings, chain stores, etc.

The GTB Light Smart & Connective goes even further!

In order to create even more efficient scenarios to maximize energy savings, the GTB Light Smart & Connective solution is installed at room level.

This makes it possible to base scenarios on human presence, the opening of windows or air quality.

The main advantages of the GTB Light Smart & Connective solution are:

Installation at room AND central system level.
Interoperability: making itself compatible with what already exists (both air conditioning/heating... as well as a possible existing BMS).
Simplicity and speed of installation, no work, no loss of activity.
A global turnkey solution, from device to SaaS including dedicated applications.
A multi-site online portal that allows you to monitor building data and create automatic scenarios.
