// Descrizione
"Reno vatio n pro ject o f a building co nstructed in 18 8 0 in Paris. The client undertakes a co mprehensive reflectio n o f energy and
eco lo gical reno vatio n o f buildings. In co mpliance with the o riginal co nstructive system and in o rder to preserve the building,
reflectio n was co nducted with bio based materials.
The existing building presents pro blems related to indo o r humidity, water infiltratio n fro m the ro o f o f neighbo ring and po o r o r
no thermic insulatio n. A face lift do ne in the 19 9 0 s added a plastic co ating o n the facades which has co ntributed to the
hydro thermal degradatio n o f the frame.
As part o f the studies, we studied the surface creatio n o ppo rtunity in elevatio n to allo w an eco no mic balance in the o verall
investment in building bio -based materials. The elevatio n was no t po ssible fo r reaso ns o f regulato ry enviro nment and lack o f
surface created -fo o tprint o f the building: 70 m² The cho ice fo r the insulatio n o f street façades was fo cused o n hemp co ncrete.
This material allo wed us to insulate the main facades and re-co ated in co ntinuity o f the material o n the spro ckets. These co uld
no t be insulated fo r o vertaking reaso ns o n the gro und o f neighbo rs, then blasted co ating at the gables were replaced with
hemp co ncrete, which adjusts the humidity o f the building. The windo ws were replaced with wo o den jo inery, do uble glazing,
high perfo rmance, and displaced o utside o f the structure to be at the level o f thermal insulatio n.
Reno vatio n with insulatio n o f facades, change wo o dwo rk, attic insulatio n and bio based materials reached facto r 4 Building

Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : The reno vatio n pro ject presented here is a private rental
use pro perty lo cated in a typical area o f the 14th arro ndissement o f Paris. This mo no pro perty embarked o n a pro ject to
impro ve and maintain the o verall quality o f the building and tenants co mfo rt. The first step co nsisted in an audit o f the building
o n the energy and technical appro aches. It came o ut that the walls o f the building acco unted fo r 40 % o f the heat lo ss. In
additio n, the disco mfo rt and the appearance o f certain diseases o n certain areas o f the building led to the selectio n o f a
suitable thermal insulatio n building materials. In o rder to ensure quality o f indo o r air and the health o f walls, breathable
insulating so lutio n in line with the existing typo lo gy was quickly co nsidered. This so lutio n, hemp co ncrete, respo nds favo rably
to the demand fo r thermal impro vements while being co mpatible with the o ld type o f mo isture-sensitive frame. It is recalled
that, and it was the subject o f o ther cards, this co mplex insulatio n thro ugh hemp can sto re carbo n and having a do uble
co ntributio n to reducing the impact o n climate change. The heating seaso n starts and tenants already evo ke a no table gain o f
thermal co mfo rt and heaters that run a little bit...
"We favo r the installatio n in the center o f Paris o f a mo re fragile po pulatio n when it co mes to stro ng rents - apo pulatio n that
unfo rtunately o ften migrates to the o utskirts o f the city. Our tenants are retired (librarian), maid, nurses, secretaries and
students. The Real Estate co mpany wants to keep this po pulatio n inside the city by o ffering a respo nsible habitat and quality.
We also ho pe by this actio n the awareness o f enviro nmental respo nsibility. " Juliette Heckmann, o wner
De scrizio ne archit e t t o nica : The wo rk o n this three-sto rey building is glo bal. The idea is to simultaneo usly so lve
mo isture diso rders, the weak thermal insulatio n and asso ciated disco mfo rts. The cho ice sto pped o n the use o f hemp
co ncrete to co ver the walls, previo usly "picked up” with a layer o f 10 cm o n the gro und flo o r and 20 cm o n the upper levels.
This insulatio n co ating ensures bo th co ntinuity: the insulatio n blanket (thanks to its co ntinued applicatio n) and capillary thus
avo iding any risk o f disease asso ciated with water retentio n in the walls.
