T ipo lo gia co nt rat t uale :
Altri meto di
Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : The criteria fo r co ntributio ns and free natural light was
insufficient o n the Lo mbard site given the o rientatio n o f the building, the po sitio ning o f windo ws and thick walls which greatly
reduce the po ssibilities o f so lar pro ductio n. Envelo pe perfo rmance criteria and renewable energy were thus privileged, no tably
thro ugh the ado ptio n o f a co llective wo o d bo iler. Thermally, the main challenge will be to ensure go o d air seal to prevent heat
lo ss.
-The external wo o dwo rk must have a go o d perfo rmance while maintaining their o riginal appearance. So me will be lined with
new jo inery inside.
De scrizio ne archit e t t o nica : The facades and ro o fs have been resto red by "DRAC, ICF NORTHEAST HABITAT" and
seeks to co mpletely transfo rm the building, currently co mpo sed o f several large trays. The building has typical flo o rs very
o pen based o n repetitive frame which allo ws the installatio n o f large typo lo gies in the early levels.
The 29 units are divided into 11 (1ro o m), 2 (2ro o m), 8 (3ro o m), 7 (4ro o m), 1(5ro o m). Large areas are pro vided o n the first
three levels, while the type 1 units will be gro uped o n third flo o r.
Co sa cam bie re st i se do ve ssi f arlo di nuo vo ? : Reno vatio n, particularly in "energy efficiency" is a central strategic
co ncern o f the gro up Rabo t Dutilleul. Other pro jects, no t exactly in patrimo ny, are already achieved this level o f perfo rmance.
Opinio ni de gli ut ilizzat o ri de ll\'e dif icio : During the inauguratio n, representatives o f the municipality o f Lille - Audrey
Linkenheld, MP - delegated municipal co uncilo r in Lille plan habitat, Estelle Ro des, deputy mayo r in charge o f the relatio nship
with so cial landlo rds, Franck Hano h, Deputy Mayo r in charge o f security, Chairman o f the Centre neighbo rho o d co uncil,
Bernard Charles, deputy mayo r in charge o f emplo yment and inclusio n and Julien Dubo is, deputy mayo r in charge o f heritage
- were able to visit a 5ro o m apartment. On this o ccasio n, Audrey Linkenheld said he was "very pleased with the co nfidence
sho wn in No rtheast ICF Ho using and generatio nal and so cial diversity o f the new pro gram in the heart o f Lille";. She recalled
"the impo rtance o f keeping families in the city center"; After this sho rt ceremo ny, elected o fficials and representatives o f the
landlo rd went to visit the residents. Amo ng them: So nia Rainaud. Since she mo ved into o ne o f the apartments o f the
residence, she is in heaven! Her new ho me is much mo re spacio us than the o ne she o ccupied until 20 February. "To day, my
family has fo ur ro o ms fo r a living, she says. Befo re, I o nly had two ro o ms fo r me and my five children"; Additio nally, her salo n
is cro ssed by a brick wall, a remnant o f the fo rmer ho tel o f Lo mbard. (so urce, The No rthern Vo ice, 24.4.20 15).

Sealing membrane hygro -regulatio n with a Sd between 0 .2 m and 4 m
Co m m e nt i:
Pro blem o f airtightness by wo rking o nly o n the o uter vertical walls. Must be sealed ho using to
ho using and therefo re also deal with each o ther. With the co nfiguratio n o f the existing flo o r
(wo o d flo o ring + insulatio n + co ncrete slab) it is difficult to ensure a co mplete seal. Leaving the beams is also a great so urce
o f leakage and thus to treat. DESCRIPTION OF SOLUTION: to co nnect the vertical membranes plasterbo ard ceiling by playing
the ro le o f tight barrier plasterbo ard ceiling. It must be scrupulo usly rigo ro us o n its applicatio n and o n the junctio n o f these
po sitio ns. Ask waterpro o f electrical bo xes. The shear walls are also great so urces o f leaks and thus treated by the pro jectio n
o f a aéro blue. To the junctio n with expo sed beams, again yo u have to be very careful abo ut applying a seal between the
suppo rt rail and the beam and rail and also placo . Attentio n to all sanitary and electrical penetratio ns.
