De scripció n de la arquit e ct ura : Regain (Bis) is a lo o ko ut to bring man clo ser to nature. We were really surprised by the
beauty o f the site. Even if the Arto is Flandres Industrial park is a place that has been reco mpo sed by the hand o f man, nature
has no netheless reasserted itself. We were to uched by the “po etic” atmo sphere; o utstanding in a business area. In particular,
the channel, the peaceful blue co rrido r inviting to travel; the wo o d planted o n the nearby slo pes, the island in ditches; twin slag
heaps, tribute to the mining culture... We wanted immediately to build a pano ramic viewpo int to place the visito r at the heart o f
this landscape. By elevating the building, it was po ssible to pro vide future o ccupants in co nstant co ntact with the enviro nment.
On the gro und flo o r, the visito r passes thro ugh a carpet o f ferns and go es to the fro nt do o r. A staircase then leads to the heart
o f the building, the large landing upstairs ho me serving all living spaces. Co nceived as a nave-atrium with a glass ro o f, this
area o ffers a 36 0 ° view: the sky and shrubs planted o n the ro o f, as well as the surro unding landscape by transparency created
thro ugh the o ffices. The living areas, o ffices and co mmo n ro o ms, surro und this atrium, balanced and symmetrically, each
benefiting fro m different directio ns and different landscapes.
On energy and the enviro nment, we tried to reach the 15th target o f high enviro nmental quality (HQE), which tends to co rrect the
eco lo gical fo o tprint ... In the case o f a co nventio nal co nstructio n; the influence o f the buildings is permanently lo st to the
detriment o f the bio diversity. We have therefo re cho sen to minimize the building impact o n the eco system, resto ring lo st
space: o n stilts, the building will be co vered with a ro o f garden.
REGAIN (bis) preserves o f maximum the so il and recreates o n the ro o f a “memo rial" o f bio diversity remo ved. We invite thus,
bio diversity in bo th the building and under the building: shrubs, grasses, bulbs and plants o n the ro o f, ferns under the building,
recreating an image as the different strata o f the fo rest enviro nment, the undergro wth and the cano py.
Si t uvie ran que hace rlo o t ra ve z : The Siziaf is an o ccasio nal co ntracto r o n building co nstructio n, this is no t its o riginal
purpo se.
The general o rganizatio n o f the pro ject between architect and co ntracto rs as well as design and co nstructio n remains
relatively much mo re co mplex when perfo rmance targets are expected.
Opinió n de lo s usuario s de l e dif icio : The emplo yees o f a co mpany feel less invested with active missio n to o perate
the bio climatisme o f a building, therefo re the auto matio n o f a number o f functio n.
Bio climatic design requires expertise to prevent disturbing effects such as glare o r risk o f o verheating, particularly as the
envelo pe is o ver-insulated.

De scripció n:
Métisse® is a range o f aco ustic and thermal insulatio n in recycled co tto n fo r building
co nstructio n. It insulates against co ld and heat, but also the no ise. It has exceptio nal aco ustics
thanks to the co tto n that co mpo ses it. The RELAIS is a netwo rk o f co mpanies acting fo r 30
years fo r the integratio n o f peo ple suffering exclusio n, thro ugh the creatio n o f sustainable jo bs.
Member o f Emmaus France, it based its actio n o n the co nvictio n that the return to wo rk o f
peo ple in difficulty is o ne way to help them preserve their dignity and regain a place in so ciety. It
develo ped fo r it several eco no mic activities which have enabled the co mpany to create mo re
than 240 0 jo bs until to day. The pro duct is manufactured o n the Park site a few hundred meters fro m the REGAIN BIS.
Co m e nt ario s:
Pro duct greatly appreciated by co mpanio ns because it is no t irritating, easily hand cut, o do rless during and after installatio n. It
is also very easy to install , its aco ustic and thermal qualities are felt in the premises in which it is placed .

REGAINS BIS is an exemplary and inno vativebuilding at several levels. It is very energy efficient (very lo w po werco nsumptio n
by a passive envelo pe), it uses 10 0 % o f the energy pro ducedlo cally, is co mpo sed o f bio -based and recycled materials, and
is co ncerned abo utthe co mfo rt and the health o f its o ccupants. The building respects aswell, the bio diversity o f the site which
is certified ISO 140 0 1 fo r 10 years no w...This pro ject is no t bo rn by chance, it co mes fro m co nfirmed experience (see
