// Descrizione
In o rder to develo p the digital (deplo yment o f Co llabo rative Co mmunicatio n Infrastructure: ICC) and to do so permanently
enter the campus in the digital age, the Lo ire Bretagne University (UBL) wished to build the fo llo wing 4 buildings :
- In the Digital Cluster Rennes Beaulieu (PNRB) o f 40 0 0 m². It is situated o n the Beaulieu campus in Rennes between the
Avenue du Général Leclerc and driveway Jean Perrin.
- In the Digital Cluster Rennes Villejean (PNRV) o f 430 0 m². It is lo cated o n the site Villejean university o f Rennes nearby
EREVE.
- In the Digital Cluster Brest Bo uguen (pN2b) o f 170 0 m². It is lo cated o n the campus o f Bo uguen Brest near the university
library.
- In the Digital Cluster Brest Iro ise (PNBI) o f 2150 m². It is lo cated o n the BIA Techno po le Brest Avenue Alexis de Ro cho n.
The develo pment o f the ICC is mainly effected within existing buildings. These fo ur buildings, are no t o nly a sho wcase o f the
pro ject, but the o nly visible parts fro m o utside the develo ped digital campus. They thus have a stro ng ro le no t o nly fro m a
functio nal po int o f view but also in terms o f symbo l and image to UBL C @ mpus particularly and UBL in general. The UBL
ho ped that the design falls within an Enviro nmental Quality appro ach and ho pes that the candidate o btains the certificatio n
issued by CERTIVEA H.Q.E® 20 11.
The UBL brand and its enviro nmental co ncern and ado pt a sustainable develo pment appro ach which is no w reco gnized in all
eco no mic secto rs and is reflected in the building by an appro ach kno wn as "High Enviro nmental Quality". On the o ther hand
the fo ur buildings are under a perfo rmance co ntract between the manufacturer and the UBL. The case study belo w fo cuses o n
the Po le Digital Rennes Beaulieu building.

Partenariato pubblico privato
Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : The Euro pean University o f Brittany (UEB) wanted to equip
its higher educatio n and research sites o f services and high quality digital to o ls, building fo ur buildings, two in Brest and
Rennes in two . - Equipped with digital tele-lecture fo r high quality video co nferencing, immersive ro o ms, studio s ... but also
designed in an ambitio us enviro nmental pro gram, do ing an exemplary pro ject.
UEB has indeed since phase pro gram engaged in enviro nmental quality appro ach to o btain the NF HQE certificatio n issued by
Co mmercial Building Certivéa. This appro ach is part o f a general search o f quality co nstructio n to limit building impacts and
co nsumptio n o f natural reso urces while ensuring a healthy and co mfo rtable enviro nment fo r its users.
To do this, UEB has used PPP, led by the pro ject co mpany Breizh Co nnect. Under the PPP, the co mpany Breizh Co nnect
pro ject is surro unded by technical service pro viders fo r the different phases o f the pro ject, a gro up o f design-build batimentaire
co mpo sed o f Eiffage Co nstructio n Bretagne, the architectural firm o f Michel Remo n, Egis prime co ntracto r buildings and digital

De scrizio ne archit e t t o nica : In the idea o f
bringing to gether fo ur digital po les despite their geo graphical distance, the
architect wanted the buildings, by design unit, thro ugh their fro ntal, their input sequence and lo bby designed "unifo rm", prepare
geo graphical scenery to better build the virtual gathering, the "co nnectio n" o f their users.
Fo r this, he put the key piece o f each building, Hall develo ped atrium to unite the functio ns it serves facing the same landscape
element, a landscape element that brings to gether: the sky o f Britain.
The architect has a plan area aro und a principle o f any height Hall co nceived as a "co nnecto r" functio nal units it serves. The
vario us pro gram elements are then co nnect to this center, fo rming a principle figure o f a cro ss. Telepho to amphitheater fo rm
o ne o f the branches o f this figure. The entrance directly reaches the center o f the figure, the lo bby, alo ng the mo no lith o f the
amphitheater. Circulatio n levels o f lead in the hall balco ny o n each level to assert this desire to bring to gether users o f each
building.
The ro ute to this entrance to the raw co ncrete mo no lith o f the amphitheater, then sets
"Site layo ut" fo r each building.
The facade treatment is exactly the same fo r each o f the fo ur buildings:
- The figurehead o f the TV amphitheater is co vered in gray plain po ured co ncrete with insulatio n o n the inside, carefully treating
the thermal bridges.
- The vo lume "slipped" abo ve the amphitheater blo ck is co ated with go ld metal cassettes with external insulatio n.
- The rest o f the facades is co ated panels Eternit NATURALIS clear, tinted, with exterio r insulatio n.
The o penings are o f fo ur types:
- Ho rizo ntal windo ws the same height in the "branches grafted o nto the lo bby
- Large rectangular windo ws o n the vo lume "o r" raised abo ve the TV amphitheater (A vertical identical pro tected bay o f
shading / visual barrier illuminates o ne side o f the amphitheater)
- Large curtain wall surfaces fo r the frame entries in buildings
- And a large windo w framing the sky Breto n, resulting fro m the pro jectio n o f a rectangular figure fro m a particular po int o f view
when in the lo bby, pro jected o n the façade as an anamo rphic Geo rges Ro usse o r Felice Varini.
Co sa cam bie re st i se do ve ssi f arlo di nuo vo ? : The fact that Breizh Co nnect site maintenance fo r the next 25 years to
the Eiffage teams pro vides stro ng reactivated if interventio n requests made by users. The co st o f this maintenance is included
in the to tal rent paid by UBL to Breizh Co nnect. The amo unt was develo ped by a glo bal reaso ning and co st effectively during
the Co mpetitive Dialo gue PPP by many ro und trips between the designer and o perato r.
Opinio ni de gli ut ilizzat o ri de ll\'e dif icio : The o ccupants are already well fitting places, digital cinemas and places o f
co nviviality and exchange. The uses are in line with expectatio ns o f the UBL. The building is very bright, thanks to flo o r
co verings, suspended ceilings and paintings cho sen but also the cho ice o f o penings and views.

The windo ws have no permanent air and inlet air is intro duced fro m the CTA lo cated o n the ro o f.Internal so urces are the

The enviro nmental appro ach applied to this pro ject is part o f a research o n co nstructio n quality: architectural architecture,
funtio nal quality, technical quality, durability, mo dularity... The co nso rtium develo ps this appro ach aro und 3 axis :
Reducing charges fo r the future user o f the building: a glo bal co st study allo wed to identify the mo st interesting technical
so lutio ns fo r building management. The building was tested fo r air-tightness and reached the French thermal regulatio n level
minus 38 %. Numero us meters are linked to the BMS, which allo ws centralized system management and ho urly pro gramatio n.
Also the BMS is co nnected to a meteo ro lo gic pro be to adapt to o utdo o r temperatures. To to p it o ff, exterio r so lar pro tectio ns
keep the building fro m o verheating and heat lo sses, they are co ntro lled thro ugh meteo ro lo gic pro bes and also manually.
Users' well-being: all materials in co ntact with o utdo o r air are class A o r A+ to ensure healthy indo o r air, light co mfo rt is
ensured thro ugh the use o f very clear flo o r co vers and wall claddings. A thermo dynamic simulatio n was led during the design
phase to guarantee thermal co mfo rt o f the users, even tho ugh there is no implemented co o ling system. A CMMS allo ws
building suers to send their requests to the facility management.
The insertio n o f the building in its site, highlighting the effo rts made to adapt to lo cal co nstraints, the building o ffers very few
parking lo ts to favo r the use o f public transpo rtatio n, existing parking lo ts are permeable to rain waters, and many bike parks (9 4
spo ts) are installed and the site is co nnected to cycling tracks, Buses are o nly 150 m away fro m the building and by 20 18 , a
metro statio n will be implemented 40 0 m away. To to p it o ff, the ro ff is vegetalized.
