Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : Euro sic Management, o n the business Plaines in
To ulo use, decided to include the Agua o peratio n in a HQE appro ach (High Enviro nmental Quality), to o btain HQE certificatio n
fo llo wing the NF Tertiary Buildings by Certivéa in 20 11.
A key prio rity was to design a building with lo w energy co nsumptio n. The pro ject had to meet the RT20 12 (French thermal
regulatio n) and aimed the level o f energy perfo rmance fo r BEPOS Effinergie 20 13 label (Po sitive Energy Building). This target
was based o n the specificatio ns established by Effinergie.
In additio n, the site must have the minimum po ssible disturbance to minimize the impact o f co nstructio n o n the enviro nment.
The perfo rmance o f the building in o peratio n is essential, the Client also favo red areas o f actio n fo r the pro per management o f
waste and the aspects o f maintainability and perfo rmance mo nito ring o f buildings and equipment.
The user co mfo rt is a co nductive line in technical and architectural cho ices o f the pro ject.
De scrizio ne archit e t t o nica : This o peratio n lo cated o n the Business Park Plaines o wned by Euro sic, co vers the
co nstructio n o f a 3 sto rey high building o f 2 350 0 m² + o ne basement level. It was designed by CDA Architects and designed /
built by the GA Gro up, which made it its headquarters. This is the first tertiary pro ject to receivethe BEPOS-Effinergie® label in
France; also certified NF Co mmercial Buildings - HQE appro ach.
The building is characterized by prefabricated co ncrete structure with a high thermal inertia. The facades are insulated with
mineral wo o l and integrate with each 2.70 m frame a standalo ne air pro cessing mo dule, ensuring the functio ns o f heating,
co o ling, ventilatio n and hygienic night free-co o ling. To limit heat lo sses o f the envelo pe, the ro o f terrace and the bo tto m flo o r
facing the parking lo t are insulated with po lyurethane respectively 12cm and 15cm thermal flo cking.
Mo reo ver, the facades are no n-lo ad bearing and junctio n with the flo o rs are co vered by a thick glass wo o l which significantly
reduces the linear lo sses. The glazing o f the building are in favo r o f the co ntributio n o f natural light while being thermally
efficient. They have a triple layer o f glass, in which inco rpo rates a mo to rized venetian blind, auto matically managed by the
centralized technical management o f the building.
As fo r equipment, heating and co o ling are insured basis by two geo thermal heat pumps reversible waterfall o n dry pro bes,
supplemented by extra by the air handling mo dules fro nt. The geo thermal heat pumps supply active slab (ceiling) guarantees
o ptimal co mfo rt hygro thermal and the lo west energy co nsumptio ns.
On the gro und flo o r, the lo bby is equipped with a heating-refreshing flo o r. In parallel to this, the air handling mo dules have a
do uble-flo w ventilatio n with heat exchanger to ensure air exchange devices premises. At the center o f the building, the meeting
ro o ms are ventilated by a do uble flo w co ntro lled central to CO2 senso rs. As fo r the lighting, it is co ntro lled by presence
detectio n and / o r absence and managed acco rding to the amo unt o f natural light. Last but no t least, 46 0 m² o f pho to vo ltaic
mo dules were installed o n the ro o f terrace.
The building is also equipped with an intelligent centralized technical management to o ptimize the o peratio n o f equipment
between them and ensure user co mfo rt thro ugho ut the year, anticipating weather co nditio ns, user behavio r and their agenda.
Agua is lo catedin the Business Park Plaines. Held by Euro sic, the park is part o f a new eco lo gical appro ach, expressing a new
impetus fo r the develo pment o f the park and pro mo ting energy savings and enhancement o f the quality o f living spaces fo r
users. Agua is lo cated in the middle o f the building co mplex alo ng an axis perpendicular to the two parallel buildings nearby. It
is part o f a landscaping plant enviro nment new and designed to recreate in the park a natural enviro nment reco nstituting a
green co rrido r that pro mo tes bio diversity o f flo ra and fauna. The building is therefo re inseparable fro m the landscape pro ject
and meets the criteria o f the HQE certificatio n and eco lo gical diagno sis established by an eco lo gist end.
CDA Architects designed a unique building, in the image o f its user GA gro up and in agreement with Euro sic who wanted a
scalable and flexible rental building use.
It has a "pro w" o verhanging o n the ro ad itself as a signal o n the Business Park, increasing the visibility o f the building, with its
signs at the to p o f so lid walls animated by thin slo ts illuminatio n and co lo red metal.
An awning brimming co vering an accessible o utdo o r terrace fo r o rganizing events in the summer, accentuates the presence o f
the building by this stro ng signal.
The main entrance is marked by a charco al gray steel cano py o n a po lished co ncrete wall lively co lo red metal slo ts. The
facades are co mpo sed o f architectural co ncrete made with white and gray marble sto nes, with po lished finish made in
facto ries GA gro up, ensuring high durability o f façades. An impo rtant part o f the facade is treated verticality and made o f glass
assemblies in all elements sto rey height, with mullio ned co mpo sed by aluminum po wder co ated grilles co ncealing Air
Treatment Mo dules (MTA). These facades o ffer exceptio nal natural light to o ccupants o f o ffices and trays are equipped with
pro ducts fro m the research and develo pment o f GA Gro up: MTA, triple frame windo w with blacko ut blind integrated, facade
elements in po lished architectural co ncrete.
