(Calculation method : RGD du 30 novembre 2007 - bâtiment d'habitation )
Being heavily involved in passive constructions, we wanted to create a thoughtful and sustainable building. We equipped our control house with a complete EnOcean wireless home automation system. This innovative technology works without any battery or wiring. The energy recovered during the manipulation is enough to emit a radio signal, which makes it possible, for example, to turn on the light. Products and systems with EnOcean technology are perfectly integrated into the usual home automation systems, regardless of whether these systems communicate via LON, KNX, BACnet, TCP / IP or Ethernet. This allows the implementation without much work of the concepts of sustainable energy management.

Owner approach of sustainability
The goal was to build an avant-garde house that reflects the philosophy of the company: our wish was to have an energy-efficient house, with efficient materials, photovoltaic panels, solar thermal panels, a powerful heat pump , all with an extremely well insulated energy envelope and a perfect airtightness (N50 = 0,26h-1). We also wanted this house to be sustainable, which is why we used EPFC certified materials and a rainwater recovery system.
Architectural description
We wanted a very modern architecture by highlighting the assets of the house which has an exceptional view to the back. All living rooms have been oriented so you can enjoy this view. We have created the space in such a way that the intimacy of the occupants is respected while keeping passive requirements in mind. The house consists of large open spaces, beautiful ceiling heights, a skylight in the kitchen and large windows.

High quality interior silicate paint, solvent free. Suitable for use in spaces used by allergic patients.
The interior painting is one of the elements with which the occupant is in direct contact and the non-harmful character is very important in this respect.

The combination of miniature energy harvesting modules and ultra-low power radio technology makes it possible to offer innovative sensors that require no maintenance. These self-powered switches and sensors therefore operate wirelessly and offer unparalleled flexibility of use as well as increased time and energy efficiency. All while limiting investment and operating costs. Wireless, self-powered sensors and switches using the EnOcean wireless standard are an ideal solution for sustainable building applications. This power supply by movement, light or temperature makes cables and batteries for switches unnecessary, as well as for collecting information from sensors such as: Temperature, water or presence sensors. The sensors and actuators can communicate directly with each other and / or can be controlled by a controller / gateway placed in the room via a cloud interface for applications requiring remote management and control via a computer or smartphone.

Reasons for participating in the competition(s)
EnOcean technology enables a smart connected home. This intelligence is invisible, it warns and also allows to control the data, this by spending no energy and emanating less waves. This technology requires less raw materials (no batteries, less cables) and allows a great modularity, that is to say that the house evolves according to the needs of its inhabitants. Finally, the smart home allows great energy savings thanks to the management of overheating and automatic shutter closing or the management of room temperatures and control of the closure of the chassis. On the other hand, the smart home also allows for a better understanding of lifestyle habits via data.
Here are the features that have been integrated into the sample house:
- energy saving
- temperature control
- Control of consumptions / productions
- Smart shading
- Consistent lowering of blinds
- Systematically turn off the lights
- security
- turn off everything
- Control of window openings and doors
- Simulation of presence
- Alarm
- Comfort
- Central visualization and control of the entire electrical installation
- Timed lighting control
- Automatic shading
- scene control
- Programmable positions for blinds and shutters
- Surgery
- PC with / without Touchscreen
- Tablet Apps
- Smartphone Apps
- Remote control
- Voice command
