Manage the light, control the heating, automate the operation of the shutters ... the home automation facilitates the everyday life of the house and provides an answer to a challenge that concerns us all: to save energy.

Combining the word "domus" (house in Latin) and the word "computer", home automation ensures - thanks to modular solutions, networked around a centralized "intelligence" - the automation of daily tasks by programming or by coordinating them. Its "business sectors" are security (alarms), comfort (shutters), energy management (heating programming) and communication (telephony, remote control).

Finally, home automation is simple or complicated?

After a bitter failure in the 1980s, it is now experiencing a revival. It is no longer perceived as a useless gadget, but as a technology that renders real services. There is no point in putting technology everywhere if it does not correspond to a specific need; we went from "everything home automation" to a "reasoned" approach that offers adapted solutions. No more gas plants whose complexity made the use impossible for ordinary mortals: the time is simplicity. It is above all to assist the user in his daily life and not to clutter multiple technological toys. Communicating, interactive, multifunctional, today's home automation makes it possible to provide an answer to everyone's needs.

For which economies?

Driven by the environmental Grenelle engine, the thermal performance of the house is a strong argument in favor of home automation. A well designed home automation system is 25 to 30% energy savings per year. The obligation to control this type of cost alone justifies the use of automation and domestic management scenarios. The role of home automation is indeed to communicate the technical equipment with one clear objective: to improve the energy efficiency of the house by informing on the overall electricity consumption and item by item. Home automation allows everyone to be aware of either malfunctions or lifestyles to change, on the other hand to have the means to control his equipment, even remotely to maximize comfort and reduce expenses.

How much does home automation cost?

The price to be paid is still quite high: it takes 50 € per m2, for a basic installation including lighting management, shutter automation, heating regulation and VDI flows (telephone, television and computer data). ), 150 € and more m2 for a facility that supports energy management, home security, sound and visual environment, etc. But this additional cost will be amortized thanks to the savings made. And you do not have to do it all at once. An installation can evolve according to the budgets and the needs of the family. And then, to begin, there are small simple and practical equipment (the presence detectors for example), which are cheap and already provide many services.

Some concrete examples of home automation

1. Control the heating

Window opening detectors stop the heating when you ventilate the room. Automatic programming reduces the temperature when you leave. The heating is regulated piece by piece from the programmer for a comfortable but controlled temperature.

2. Manage lighting

When you leave your home, you turn off all lights and watches with centralized lighting management. A motion detector can be very convenient when you enter the arms loaded in the house or dressing room: it triggers the lighting. He also ensures that the lamps do not stay lit if no one is in a room. By developing "lighting scenarios" based on your activities, you consume only light when you need it. The "turn everything on / off" function provides extra comfort. It is thus possible to extinguish with a single gesture all electrical devices that must not work. When you come home, a simple touch of a button is enough to turn on everything you need, such as heating, lighting or even the radio.

3. Order blinds and shutters

Automatically closing all shutters as soon as night falls in winter to conserve heat allows up to 10% heating savings. In summer, you can program the descent of the electric awnings as soon as the sun comes out. You gain up to 9 ° C on the temperature in the house and avoid the need for air conditioning. And these blinds will rise automatically if the wind rises. Scheduling shutters at fixed times can be combined with heating via a power manager. Example: at 10 pm, shutters shut for the night is accompanied by a drop in temperature. On the contrary, at 7 am in the morning, the shutters open and the heating automatically resumes.


An appointment to go further

Organized by the Promotelec association, the national days of home automation are held from 15 to 30 November 2011 throughout France. For a fortnight, you will be able to visit inhabited housing or demonstration apartments equipped with home automation solutions. The opportunity to see how it works in real life!
