// Descripción
An atypical pro ject by its size:
270 private dwellings,
30 flo o rs
A high building signed by Zehrfuss built in the 6 0 ies.
lo ggia balco nies
a glass paste facade crumbling and falling o n bystanders.
The co ndo minium installed scaffo lding to secure its surro undings. A facelift is needed but this ro und is no t insulated and
heating lo ads are heavy.
Why no t imagine a mo re glo bal actio n? the co -o wners did an energy audit, then mo unted an ambitio us energy and
architectural impro vement pro gram, unusual fo r a private co ndo minium. The o peratio n was co nducted smo o thly. Usually,
decisio ns are hard to take in co ndo miniums and o ften pushed back fro m o ne year to ano ther. Meanwhile the building is
deterio rating. The peo ple do no t have the same status, the same inco me, and no t necessarily the same interest. If everyo ne is
investing heavily its ho using, public areas and the "co mmo n go o d" are asso ciated with "fillers" high financial.
in Super-Mo ntparnasse, a virtuo us pro cess began with the co nsent o f co -o wners, thanks to the co mmitment and dynamism
o f the unio n co uncil, the participatio n o f many stakeho lders (APC, city o f Paris etc.) and especially thro ugh the digital mo del.
Indeed, the BIM has been a great dialo gue to o l to understand the issues, explo re hypo theses, agree and especially reassure
each o wner still cautio us abo ut the idea o f
spending a lo t o f mo ney o n things that do no t really see (insulatio n). He was
able to understand the who le pro ject, view her apartment and her apartment co nsequences, fo llo w the site daily, be warned
interventio ns inside etc.
The site is in pro gress. A co py requalificatio n that values
each apartment and illustrates use o f BIM as a co mmunicatio n
to o l and o wnership o f the pro ject to wards a Master o f unpro fessio nal wo rk.

Filo so f ía am bie nt al de l pro m o t o r : The Supermo ntparnasse to wer designed by ZEHRFUSS in 19 6 8 sho wed different
patho lo gies:
- mo lten glass facade with elements that fall,
- high energy co nsumptio n bill (inefficient carpentry, insulatio n failure),
- district heating difficult to regulate o n thirty flo o rs.
De scripció n de la arquit e ct ura : The audit established by PAZIAUD has allo wed to target the po ints o n which it was
necessary actio n to impro ve the energy balance o f the to wer:
- Insulatio n o f walls / treatment o f thermal bridges.
- Replacement o f windo ws.
- Replacement o f the exhaust o penings
- Implementatio n o f humidity sensitive ventilatio n
The architects have addressed these po ints in o rder to respect the architecture o f the to wer.
This results in particular in the cho ice o f materials, with insulatio n o f different thicknesses facades but o f equal perfo rmance to
the shape o f the building.
The insulatio n is co vered with a facade cladding types "shells MD" is a cladding system repo rted with ventilated air space has
base metal cassettes what is inno vative fo r a building o f this size.
Maintaining visual co mfo rt fo r the o ccupants and despite the additio n o f external insulatio n, light glazing is identical to the o ld
wo o dwo rk, thanks to o ptimizatio n pro files and built carpentry, while allo wing better perfo rmance aco ustic and thermal.

// Concurso
Il s'agit de la réno vatio n thermique d'un immeuble de grande hauteur, co nstruit dans les années 6 0 .
Cette réno vatio n de part les perfo rmances o btenues, la technicité et le co ntexte (co pro priété de 270 lo gements en milieu
o ccupé) est citée en exemple par la ville de Paris et l'APC.
Architecture PELEGRIN created the digital mo del o f the existing building then enriched it all alo ng the pro ject with technical
so lutio ns selected by the team and the o wner.
BIM was a co mmunicatio n to o l and live decisio n to o l fo r the 270 co -o wners. It allo wed "quick decisio ns" when decisio n
timescales fo r co ndo miniums is usually terribly lo ng and the multiplicity o f statuses (living o nsite o wners and landlo rds,
retired and firts-time buyers, and mo re...) do n't make things easy. During presentatio ns in fro nt o f the co -o wners, each
inhabitant o f the building co uld co mprehend the pro ject in its glo bality and visualize the co nsequences fo r their o wn apartment.
Witho ut BIM, the decisio n to vo te the pro ject wo uld have required o ne year o r even lo nger.
All the design team (architects, engineers, etc...) used the same digital mo del.
Fo r the co mpanies, BIM facilitated the co nstructio n phase in an o ccupied site: marked windo ws (what cho ices, what co lo r) but
also the co o rdinates o f each inhabitant to make each interventio n easier and ensure as lo w nuisance as po ssible.
