This project is a personal project of the architect Catherine PERRIN LABEUR. This home for a family of five must meet the criteria defined by the Passiv'Haus. For its construction, it is imperative to use materials used in the region and use the expertise of local businesses. The terrain is steep and has, since its upper level, a clear view of the Rhone valley from the east. This view will be staged by the project. the project includes a large living area located in the upper part and the master bedroom with bathroom. On the lower floor is space for children consists of 3 bedrooms with private shower, desk and closet, the "lungs" of the passive house in which are grouped all the "vital organs" of a passive house.
Sustainable development approach of the project owner"Today the passive house is often associated with wood construction, says Catherine Perrin-Toil. But there is no question for us to build wooden full Provence! Our challenge was to build a passive house with commonly used methods buildings in our region ... ".
To assist in the design of this house, it uses an experienced heating engineer Hugues Brassy of Diagnos Thermo design office. Together they define a design specification:
- Achieve a compact design to limit m2 of contact with the outside walls
- Define a constructive fashion to identify from the first sketches thermal bridges to be able to provide solutions well in advance.
- Favoring large openings to the south that will be protected from the summer sun with solar radiation and winds that will capture the energy in winter
- Limiting the number and the surfaces of the openings northeast
- Favoring systems openings strikes rather than sliding windows for better airtightness
- Design a sealed outer envelope in which will limit the crossings to the outside, potential sources of air leakage. All essential crossings will be identified and treated to reduce the risk of leaks.
- Install a dual flow ventilation inside the sealed casing coupled with a Canadian wells to optimize the efficiency of ventilation in winter and summer.
All these points will affect the architectural choice of the house.
The final study results in a need for heating 14 kWh / m2 year, total primary energy consumption of 110 kWh / m2.an and overheating rate of only 4%, in a region where it takes with hot weather. The permit was deposited before 1 January 2013, the RT2012 has not applied to the project.
Architectural descriptionFacing south, the house of 250 sqm, by its sheer volume and wide openings naturally let the heat out. To take advantage of the view from the day room, there were other solutions to implement them on the upper part of the house. The strong slope of the land enabled the development of a long bridge by a corridor and a terrace that serves the highest level including the parts of day and the master bedroom. On the lower floor are the children's rooms, office and technical room.

"We made some design choices that were dear to us, but that does not necessarily facilitated the performance required by the label, she says. That's what made the particularly exciting year! For clients, I probably would have avoided some difficulties, especially from the perspective of the management of thermal bridges. "

Reasons for participating in the competition(s)For us, this passive house project should not be associated with the concept, ecology aware sense. We prefer the concept of responsible citizenship to define our approach. We chose the passive building in a Mediterranean context, by focusing particularly on summer comfort, heating needs are low also. To achieve nosu avosn set targets in line with our design office:
- a compact construction to limit m2 of contact with the exterior walls
- constructive way to identify from the first sketches thermal bridges to be able to provide solutions well in advance.
- favoring large openings to the south that will be protected from the summer sun with solar radiation and winds that will capture the energy in winter
- limit the number and the surfaces of the openings northeast
- focus openings Systems strikes rather than sliding windows for better airtightness
- a sealed outer envelope in which will limit the crossings to the outside, potential sources of air leakage.
- double-flow ventilation inside the sealed casing coupled with a Canadian wells to optimize the efficiency of ventilation in winter and summer.
