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 script io n archit e ct urale : 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. // Energie Consommation énergétique Be so in e n é ne rgie prim aire : 10 ,30 kWh EP/m 2 /an Be so in e n é ne rgie prim aire bât im e nt st andard : 77,50 kWh EP/m 2 /an Mé t ho de de calcul : PEB - Wallo nie CEEB : 0 kWh PE / € Co nso m m at io n d'é ne rgie f inale : -16 ,0 0 kWh EF/m 2 /an Ré part it io n de la co nso m m at io n é ne rgé t ique : Primary Energy - Heating: 12.1 - Co o ling: 16 - Ho t Water: 6 .3 - Lighting: 17.9 - Auxiliaries dist .: 0 .8 - Auxiliary ventilatio n: 9 .1 - Pho to vo ltaic: - 51.9 Final Energy - Heating: 4.7 - Co o ling: 6 2 - Ho t Water: 2.5 - Lighting: 6 .9 - Auxiliaries dist .: 0 .3 - Auxiliary ventilatio n: 3.5 - Pho to vo ltaics: - 20 .1 Performance énergétique de l'enveloppe UBat de l\'e nve lo ppe : 0 ,6 0 W.m -2 .K-1 Plus d'inf o rm at io n sur l'e nve lo ppe : 120 mm glass wo o l (R = 3,75m²K / W) fo r facade insulatio n treatment with thermal bridges per unit length o f the facades-flo o r junctio ns, by implementing 120 mm slab no se 120 mm glass wo o l po lyurethane (R> 5m²K / W) 130 mm flo cking ro o f underside o f the bo tto m flo o r o verlo o king basement with heat treatment o f inertia beams co ncrete highlighted by the absence o f suspended ceiling Co e f f icie nt de co m pacit é du bât im e nt : 0 ,23 // EnR & systèmes Systèmes Chauf f age : Po mpe à chaleur géo thermique Autres ECS : Chauffe-eau électrique individuel Raf raîchisse m e nt : Po mpe à chaleur géo thermique Autres Ve nt ilat io n : Ventilatio n naturelle Surventilatio n no cturne Do uble flux avec échangeur thermique Ene rgie s re no uve lable s : So laire pho to vo ltaïque PAC géo thermique sur so ndes Pro duct io n d'é ne rgie re no uve lable : 10 0 ,0 0 % Heating and Co o ling Generato rs: 2 reversible geo thermal heat pumps, cascade, o n dry pro bes - 22 pro bes 10 0 m transmitters: Basic: active slab Activ'Co ncept (GA pro duct) + extra: air handling mo dules in fro nt Ho t Water Pro ductio n Ho t water by individual electrical ho t water cylinders in the sanitary Ventilatio n Heat reco very ventilatio n do uble flo w, free-co o ling, night ventilatio n 46 0 m² o f pho to vo ltaic panels fo r an installed capacity o f 72.6 kWp So lut io ns am é lio rant le s gains passif s e n é ne rgie : free co o ling, inertia o f the co ncrete, geo -co o ling via active slab midseaso n Bâtiment intelligent GT C : BMS Gapéo (GA pro duct) http://www.ga.fr/no s-techno lo gies/gapeo Sm art Grids (ré se aux int e llige nt s) : Smart-Grid ready building that redistributes its excess pro ductio n to two o ther o ffice buildings in the business park // Environnement Emissions de GES Duré e de vie du bât im e nt (anné e ) : 6 0 ,0 0 an(s) Analyse du Cycle de Vie : Plus d'inf o rm at io n sur le diagram m e ACV : ACV fo r all materials o f structure and sub-trade Im pact s de s m at é riaux de co nst rut io n sur le s é m issio ns de GES : 7,49 Im pact s de s m at é riaux de co nst ruct io n sur la co nso m m at io n é ne rgé t ique : 27,6 2 kWhEP Eau et qualité de l'air intérieur, santé et confort Qualit é de l'air int é rie ur : implementatio n o f pro ducts and materials with eco -labels and regulato ry labeling A o r A + (HQE standard TP o n target 2) Co nf o rt & sant é : Daylight facto r calculatio ns were made to ensure minimal natural light in the premises Glazing o f central po rtio ns fo r intake o f natural light Intelligent lighting with auto matic dimming to ensure 30 0 lux o n the wo rkstatio n, depending o n the natural light Auto mated blinds co ntro lled by the BMS acco rding to the o rientatio ns, time slo ts ... with manual o verride, to o ptimize the so lar and light inputs and fight against the dazzle o f wo rkstatio ns Co nf o rt aco ust ique : Aco ustic study fo r the design and realizatio n o f aco ustic bafles po st-build steps to validate the HQE High Perfo rmance level requirements. // Produits Activ' Concept Fabricant : Gro upe GA Co nt act f abricant : ga[a]ga.fr Sit e Int e rne t f abricant : http://wwww.ga.fr Cat é go rie de pro duit : Génie climatique, électricité / Chauffage, eau chaude De script io n: Activ' co ncept is based o n active slabs precast co ncrete where water systems were integrated.
