// Descrizione
This is the co mbinatio n o f a unique pro gram co nsisting o f the receptio n and acco mmo datio n o f heirless peo ple, aiming fo r a
return to auto no my, and a green building pro ject. Nine studio type units , in an enviro nment with ro ad co nstraints, are
o rganized aro und a stro ng co mmunity life. This pro ject includes, in interio r spaces, a receptio n desk, a multipurpo se meeting
ro o m, a lo cal care, and a laundry ro o m, linen ro o m, and o utdo o r spaces, an o rganic garden and henho use self-pro ductio n
with dedicated equipment.
The ambitio n and the means fo r a green building have been made effective by achieving a passive building with ho t water by
so lar energy, setting up a natural pro tective shield no ise fro m the track and rainwater harvesting to use irrigatio n o f cultivated
areas.

Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : The high-quality so cial ho using pro ject to wards
po pulatio ns in large marginality called "Les Prytanes II" was bo rn fro m a neighbo ring o peratio n mo re successful small scale
in a neighbo ring residential hamlet, Luynes, next to Aix en- Pro vence: in 20 0 9 , PACT Rhô ne Bo uches-du-placed at dispo sal
o f the asso ciatio n Alternative So cial Habitat, which aims to “defend the right to ho using and the right to health, the dignity o f the
mo st vulnerable”, a resto red villa became “Prytanes” o peratio n.
In the Athenian demo cracy Prytanes, fro m the five hundred elected the ball (the Co uncil), have a central po litical ro le, but their
po wer is limited. They assume the institutio ns o f o rganizatio nal and o peratio nal missio ns. The Prytanes reside day and night,
acco mmo dated, ho used and fed by the city, in an adjo ining building ... They are thus able to enter the sessio n at any time.
Fro m the success o f this o peratio n fo r users is bo rn the o peratio n “Prytanes II” co nsisting in the idea o f allo wing these peo ple
to reco ver in a place where they decide fo r themselves, what they want to do , a shared place with high to lerance and where the
co llective and the individual make participatio n an insertio n to o l into the city.
The partnership PACT 13 / HAS - Habitat Alternative So cial / Team Wo rk o f Master with architect Anne VADON the heating
engineer BIO CONCEPT Frédéric MICHEL was develo ped in this co ntext o f equitable and sustainable develo pment. The
pro gram was o rganized fro m existing ho mes in 9 ho using units, co mmunity living spaces o f reintegratio n assistance:
receptio n hall, multi-purpo se so cial living ro o m space nursing, laundry - co mmo n laundry - sanitary, technical ro o m receiving
all co mmo n equipment and energy metering. It has also been so ught in this pro ject, a saving in energy implemented and
auto no my in terms o f public facilities. Thus was bo rn a place upgraded co mpared to its co nstraints, and lo w energy
co nsumptio n, thus also bio climatic as po ssible, yet easy to use every day: A pro gram o f pro viding a passive building has
established itself with a seal to perfect air, the quality co ntro l o f indo o r air and an energy metering fo r dwellings. The o peratio n
is thus part o f the pro cess BDM - Mediterranean Sustainable Buildings and requires o ngo ing suppo rt that can be envisaged
that is perpetuated in o ther places and in o ther fo rms, no do ubt…
De scrizio ne archit e t t o nica : The treatment by the pro ject management team, building structure, its wrapping and o utdo o r
facilities was a reflectio n o f the passive co nstructio n and bio climatic appro ach stems fro m the will o f the Client and the
o perato r, in a summer go al o f co mfo rt as winter to the attentio n o f a reinsertio nable po pulatio n in an o rdinary life.
After identifying the site reso urces, and co nstraints, (website suburban near a ro ad with heavy traffic and a railway track, but still
natural area - fo rest land and agricultural- to upgrade, zo ne lo w seismicity, land subject to the risk o f shrinkage and swelling
clays).
Building realizatio n o f the co ncepts are bo rn o f simple ideas:
- Use direct so lar heat to pro duce ho t water and, co nversely, o ccultatio ns systems berries and so lar shields summer
maneuver by curtains manual
- Using the natural inertia o f certain materials (paving)
- natural cro ss ventilatio n enabling the o peratio n o f passive character
- structure is wo o d and insulatio n in natural wo o d wo o l surface co atings to lo cal sands and lime applied manually
- co ver in traditio nal curved tiles with Geno ese pro tectio n against rain
- Circulatio ns ho rizo ntal slats o f wo o d galvanized steel substrates witho ut co ating o r additio nal maintenance.
Ho wever, implementatio ns were highly technical:
- High iso latio n o f the envelo pe and pushed treatment o f thermal bridges,
- efficient so lar panels - Machineries and co unting calo ries in a dedicated technical ro o m
- external jo inery in aluminium pro files and wo o d reinfo rced insulatio n triple glazing
- co lo urful co ated Canvas high weather resistance,
- auto no mo us Sanitatio n with co mpact filter massive zeo lite ...
Like these pro cesses, the o utdo o r areas are do o med to remain in its natural state:
- traffic vehicles and pedestrians o n stabilized earth
- very slight fence do tted with vegetatio n fo rming natural screen against the nuisances o f the ro ad,
- vegetable garden to residents as part o f integratio n activities and passive pro tectio n against fires the nearby fo rest.
In additio n to the stro ng enviro nmental pro visio ns, a “green site Charter” was established, requiring co mpliance with a number
o f site o rganizatio n criteria by the intervening co mpanies.

The lo catio n o f the pro ject in the heart o f the to wn o f Aix en Pro vence, between the to wns o f Luynes and Gardanne, allo ws us
to affirm that we are in the "temperate climate" catego ry. Altho ugh the Mediterranean climate characterizes us a little mo re.
During the pro ject design phase and during its implementatio n, the energy co nservatio n and eco no my have been o ur
leitmo tiv. Indeed, there is no independent heating system, because the Prytanes 2 building is a passive building. Mo reo ver,
there is no need fo r air co nditio ning as a natural ventilatio n thro ugh-pro cess (perfo rmed o vernight) allo ws to refresh the
ho using units. Then we set up a so lar co ntro l system pushed, wich allo ws, thro ugh ho rizo ntal, vertical blinds and independant
fabrics to regulate sunshine living ro o ms. Impo rtantly, do mestic ho t water, which is mo stly pro duced by so lar. And finally, all
light bulbs are lo w co nsumptio n and LEDs, and appliances quantity is reduced to the bare needs o f users.
