Cheap GTB

What costs for a GTB?

Reminder: what is a GTB?

GTB, or Technical Building Management, designates the system which makes it possible to supervise equipment such as air conditioning, heating, ventilation, lighting, etc. The primary objective of a GTB is to save energy thanks to the automation of energy-consuming devices in particular.

Intelligent building management thus makes it possible to optimize uses according to the environment, save energy and improve the performance of equipment.

Beyond a benefit for the environment and an economic benefit, GTB improves the daily comfort of occupants for a healthy and pleasant environment.

GTB collects data, analyzes it and acts on the electrical components using sensors and actuators.

advantages of a GTB

The advantages of a GTB for your building:

  • Collection and storage of data relating to the building (operating times, average temperatures, cooling time of a room, etc.) for consumption monitoring
  • Automation of devices to avoid energy waste (actuators allow devices to start or stop automatically)
  • Optimized occupant comfort (temperature, air quality, etc.)
  • Optimized device lifespan (predictive maintenance)
  • Reduction of operating costs (maintenance, servicing)

What is the GTB Smart & Connective made of?

Depending on the needs of the building, your integrator will provide you with a tailor-made formula for suitable IoTs. Here is generally what a “light” GTB from Smart & Connective looks like:

  • 1 automaton (every 20 IoTs): the real brain of the system, the automaton collects the data, analyzes it and launches automatic corrective measures to comply with the rules put in place. If your scenario involves a fixed temperature, the shutdown of a device in the event of detection of an open window... the actuators will automatically launch measures to correct an operation. The CEOS automaton from Smart & Connective has on-board intelligence which allows it to collect data, analyze and sort it in order to send only the most relevant ones to the Cloud. In the event of an unexpected interruption of the internet connection, the controller keeps the data for up to 30 days and allows the continuity of your settings and compliance with your scenarios.
  • 1 presence detector per room : in order to create effective energy saving scenarios, it is recommended to base them on the human presence in a room. It will therefore be possible to turn off selected devices when a room is detected empty, or to establish scenarios based on time and attendance statistics, for example. The Omnis presence sensor from Smart & Connective is camera-free, non-intrusive and highly reliable ( over 95%* ).
  • IoTs in each room : depending on the elements you want to monitor, Smart & Connective or partner sensors and actuators are at your disposal. Indoor air quality, temperature, light, humidity, occupancy of a workstation, cleaning status of a room, brightness, door or window opening, leaks, etc.
  • Other IoTs are also essential in common areas (sanitary facilities, meeting rooms, cafeteria, etc.) to know in real time the presence, the level of consumables, etc. You will thus be able to create more precise and more efficient facility management scenarios.
  • The overall GTB Smart & Connective system is controlled from the online portal which allows you to view data and create scenarios and schedule alerts.

Define your needs to anticipate the costs of your GTB

The installation of a BMS in an existing building as part of an energy renovation must raise several questions before getting started.

  1. Interoperability : does the chosen solution make it possible to integrate new elements in the future if needs evolve? If a GTB already exists, can it be easily added to it? Communication protocols must then be studied carefully.
  2. Hardware reliability : the benefit of a BMS is to extend the lifespan of your devices. Choosing unreliable IoTs or PLCs would be counterproductive if they have to be changed after a few months!
  3. Relevance of IoTs: does the chosen solution allow me to select the relevant sensors and actuators for the configuration of my building? Is the solution tailor-made?
  4. Ease of use: is the chosen BMS complex and does it require specific training to use it? What would the training cost be for my human resources?
  5. Does the IoT solution require an annual license ? If yes, what is the amount?
  6. Is there a cost for data storage?
  7. What about the maintenance contract with my integrator?
  8. Does the GTB chosen allow my building to benefit from financing aid such as CEE sheets (class A or B)?

Drawing up specifications for your energy renovation will allow you to better estimate the cost of your GTB.

Focus: CEE sheets, what funding to expect for your GTB?

Energy Savings Certificates were set up by the government to encourage energy renovation work and thus reduce the country's energy consumption. The operation is simple: energy suppliers (the “obligated”) must pay a sum to individuals or professionals carrying out energy saving work.

The CEE sheets make it possible to standardize the type of work to be carried out and to calculate the amount of aid, based on criteria such as the surface area of the building, the geographical area (3 distinct areas depending on their more or less hot climate) and the lifespan of the GTB.

When installing a BMS in your building, the uses taken into consideration will be heating, domestic hot water, cooling/air conditioning, lighting and auxiliaries. The CEE sheet in question is the BAT-TH-116 sheet, intended for tertiary buildings.

“The acquired or improved technical building management system ensures, through a centralized automation system, class B or A regulation functions within the meaning of the aforementioned standard for heating use and, where applicable, water uses domestic hot water, cooling/air conditioning, lighting or auxiliaries. »


Reduce costs with Smart & Connective’s “light” GTB

Today, less than 6% of tertiary buildings are equipped with an automation and control system (as a reminder, it will be made compulsory for certain buildings by the BACS Decree from 2025!). This can be explained in particular by often prohibitive prices, an offer that is too complicated with multiple contacts, or a BMS that is too complex for buildings without real needs (see our article Do I need a BMS for my building? ).

This is why Smart & Connective has set itself the mission of democratizing GTB and making it accessible to as many people as possible, thus promoting large-scale energy savings.

Comment ?

  • By offering a lightweight turnkey BMS, focused on the energy-intensive components of a tertiary building (such as offices, communities, schools, etc.)
  • By striving to offer competitive prices to be accessible to small and medium-sized businesses
  • By promoting the interoperability of the elements of the solution to adapt to all situations
  • By working hand in hand with integrators, single point of contact for the installation of a BMS (hardware AND software) and by offering them a quick solution to install ( no code )
  • By simplifying the use of tools as much as possible to reduce training costs.

Concretely, what are the prices of a GTB?

On average, the cost of a classic GTB is between €25 and €30 per m2.

The Smart & Connective solution is generally between €5 and €20* per m2. This does not include financial assistance from CEE sheets.

Regarding the return on investment, it is generally 6 years, but this indicator should be taken with a grain of salt. Indeed, the efficiency of a BMS must also be linked to the human factor. For example, if the occupants of a building are little involved in energy saving initiatives, the installation of a BMS will have spectacular results compared to the results of a BMS installed in a building with occupants who behave exemplary!
