Co ntractant général
Dé m arche dé ve lo ppe m e nt durable du m aît re d'o uvrage : We design and build fo r real estate develo pment quality
ho mes, co nfo rm to po sitive energy standard (BEPOS) and at an affo rdable co st made po ssible by the standardizatio n o f o ur
pro ducts. The timber frame particularly has advantages such as the ability to be easily industrialized, machined and co nveyed,
with a reduced manufacturing co st in the pro ductio n o f gro uped units.
Our ho using co ncept was bo rn o f a mature reflectio n o n the co nditio ns needed to create go o d quality ho using. Our bias:
reduce what can be, as the surface areas witho ut, co mpro mising o n quality and livability o f ho using.
Our demand fo r quality allo ws us to o ffer po sitive energy standard (BEPOS) ho using with implementatio n o f better finishes
than co nventio nal standards, but also better in the regulato ry requirements.
These ho uses are fo r pro perty develo pers and private investo rs wishing to build several ho using.
De script io n archit e ct urale : Our bias was to reach a po sitive energy ho memade (future RT 20 20 ) while retaining the
lo o k o f a traditio nal ho use. The timber frame o r perfo rmance are o nly ways that to thermal excellence with an affo rdable co st,
but the exterio r and interio r architectural appearance is identical to what is do ne to day in o rder to pro tect the enviro nment and
prevent disruptio n to end- user wishes .
In additio n, we to o k care o f traffic and internal layo ut to make this 8 0 m2 ho use as co mfo rtable as a ho me that wo uld be 10 o r
20 m2 larger.
Et si c'é t ait à re f aire ? : We have to evo lve and we believe it is mo re relevant to build o ur ho mes in "villages"because we
can po o l the co st o f pro ductio n and heating thanks to the co mmo n pellet wo o d bo ilers o f which the co st beco mes affo rdable
fro m 20 units.
Opinio n de s o ccupant s : Occupants are delighted, it co sts no thing and the feeling abo ut interio r co mfo rt related to wo o d
is very pleasant. The no ise level is high perfo rmance (it is lo cated 150 m fro m Beauvais Airpo rt and we hear no no ise).
The air quality is truly different thanks to the do uble flo w.
Interio r no ise are greatly reduced with thick walls o f 15cm at screeds o n each level
Occupants are all satisfied in every po int.

De script io n:
Our techno lo gy is based o n the principles o f passive ho use (Psi = -0 .0 53). The insulatio n o f
the slab is achieved with panels o f extruded po lystyrene (XPS). The qualities o f this insulatio n
are: - Very high mechanical resistance - Ro t-pro o f and unaffected by water - No impairment o f
thermal and mechanical perfo rmance o ver time Perfo rmance (Ue) fo undatio ns o f 0 .1110 W /
m2. ° C. It also allo ws us to use o nly a small amo unt o f co ncrete (less than 10 m3 per ho use)
po ured inside the fo rmwo rk XPS. The advantage o f this metho d is to have a perfectly insulated
slab that can be easily recycled during demo litio n leaving no po llutio n o n the gro und (no dust
o r rubble mixed with so il). To impro ve insulatio n o f the flo o r, we inco rpo rate 5cm insulatio n co vered with a 35 mm cap and a
tile o f 15 mm. This metho d also has the advantage o f facilitating the applicatio n o f accessibility regulatio ns (PMR standards Disability Access). During installatio n, the wall is embedded accurately into the sill attached to the slab and the jo int o f the XPS
insulatio n walls. Our walls are made o f a wo o den frame o f 18 0 mm co ated o n each side with a Fermacell plate. On the o uter
wall, we add a high-density insulatio n in mineral wo o l co vered with a film and a grip co ating fo r receiving the plaster. Inside the
Fermacell plate is co vered with the vapo r barrier film, a technical bulkhead o f 50 mm filled with new mineral wo o l and a BA13
plaster plate to directly receive the finishing paint. Perfo rmance (Ue) o f o ur walls and o ur flo o rs is 0 .10 53 W / m2. ° C.

// Environnement urbain
Enviro nne m e nt urbain : The direct enviro nment o f this mo del ho me is very special because the ho use is lo cated less
than 20 0 m fro m the slo pes o f Beauvais-Tille Airpo rt. This nuisance was interesting to check the aco ustic co mfo rt o f the ho me.
This set apart, the idea was also to successfully integrate in a classic suburban urban BEPOS a ho use witho ut this o ne do es
co me to break with the rest o f the ho uses. This ho use is visually similar to o ther elms so lar panels integrated into the ro o f.

Economic: This ho me is achievable in exceptio nally sho rt time thanks to the « dry chain », mo bilizing teams o nly fo r a limited
time : transpo rtatio n takes o ne day and co nstructio n times are reduced (between 6 and 12 weeks ) = less energy and waste.
Quality: Because co nstructio n savings do es no t necessarily means sacrificing quality, equipment and finishes o f the Alistair
ho use guarantee co mfo rt with high -end technical equipment to save energy needs.
Accessible: The Alistair ho use was designed to be mass-pro duced o n a large scale in individual o r gro uped ho using, private
o r public.That is why Eco lo co st is able to o ffer a quality / price ratio , thanks to pro cess inspired by the requirement o f quality
and inno vatio n in the auto mo tive industry by mo bilizing less energy to pro duce it.
