// Description
This pro ject is a perso nal pro ject o f the architect Catherine PERRIN LABEUR. This ho me fo r a family o f five must meet the
criteria defined by the Passiv'Haus. Fo r its co nstructio n, it is imperative to use materials used in the regio n and use the
expertise o f lo cal businesses. The terrain is steep and has, since its upper level, a clear view o f the Rho ne valley fro m the east.
This view will be staged by the pro ject. the pro ject includes a large living area lo cated in the upper part and the master bedro o m
with bathro o m. On the lo wer flo o r is space fo r children co nsists o f 3 bedro o ms with private sho wer, desk and clo set, the
"lungs" o f the passive ho use in which are gro uped all the "vital o rgans" o f a passive ho use.

Dé m arche dé ve lo ppe m e nt durable du m aît re d'o uvrage : "To day the passive ho use is o ften asso ciated with wo o d
co nstructio n, says Catherine Perrin-To il. But there is no questio n fo r us to build wo o den full Pro vence! Our challenge was to
build a passive ho use with co mmo nly used metho ds buildings in o ur regio n ... ".
To assist in the design o f this ho use, it uses an experienced heating engineer Hugues Brassy o f Diagno s Thermo design
o ffice. To gether they define a design specificatio n:
- Achieve a co mpact design to limit m2 o f co ntact with the o utside walls
- Define a co nstructive fashio n to identify fro m the first sketches thermal bridges to be able to pro vide so lutio ns well in
advance.
- Favo ring large o penings to the so uth that will be pro tected fro m the summer sun with so lar radiatio n and winds that will
capture the energy in winter
- Limiting the number and the surfaces o f the o penings no rtheast
- Favo ring systems o penings strikes rather than sliding windo ws fo r better airtightness
- Design a sealed o uter envelo pe in which will limit the cro ssings to the o utside, po tential so urces o f air leakage. All essential
cro ssings will be identified and treated to reduce the risk o f leaks.
- Install a dual flo w ventilatio n inside the sealed casing co upled with a Canadian wells to o ptimize the efficiency o f ventilatio n
in winter and summer.
All these po ints will affect the architectural cho ice o f the ho use.
The final study results in a need fo r heating 14 kWh / m2 year, to tal primary energy co nsumptio n o f 110 kWh / m2.an and
o verheating rate o f o nly 4%, in a regio n where it takes with ho t weather. The permit was depo sited befo re 1 January 20 13, the
RT20 12 has no t applied to the pro ject.
De script io n archit e ct urale : Facing so uth, the ho use o f 250 sqm, by its sheer vo lume and wide o penings naturally let the
heat o ut. To take advantage o f the view fro m the day ro o m, there were o ther so lutio ns to implement them o n the upper part o f
the ho use. The stro ng slo pe o f the land enabled the develo pment o f a lo ng bridge by a co rrido r and a terrace that serves the
highest level including the parts o f day and the master bedro o m. On the lo wer flo o r are the children's ro o ms, o ffice and
technical ro o m.
Et si c'é t ait à re f aire ? : "We made so me design cho ices that were dear to us, but that do es no t necessarily facilitated the
perfo rmance required by the label, she says. That's what made the particularly exciting year! Fo r clients, I pro bably wo uld have
avo ided so me difficulties, especially fro m the perspective o f the management o f thermal bridges. "
