Filo so f ía am bie nt al de l pro m o t o r : The o bjective o f the pro ject o wner was to realize an exemplary building bo th in
terms o f enviro nmental quality as its energy co sts. Already, with its Natura 1 (set o f five o ffice buildings with a to tal flo o r area o f
6 550 m² surface area), Perial Develo pment building has reached the go al Very High Energy Perfo rmance o n the So phia
Antipo lis site. Eager to go much further and in the co ntinuity o f an o verall enviro nmental appro ach, Perial Develo pment has
referred to its new building "Natura REC" in Mo ugins, a labeling Mediterranean Sustainable Buildings Go ld level and a real
perfo rmance to Po sitive Energy Building. It is indeed a real "Po sitive Energy" co vering all uses beyo nd regulato ry
co nsumptio n, plus co mpensatio n o f part o f embo died energy co nstructio n. The Client is also co mmitted in the Emergence
pro gram o n so lar co o ling even if that so lutio n was no t selected. Naturally, the views o f ambitio ns fo r this building, the Client
wanted to achieve exemplary o peratio n registering in the pro cess PREBAT Act-which he wo n in 20 10 . The Natura BEPOS REC
is a 2 co pies Buildings co mplex o n the map Energy and Enviro nmental. Fro m an enviro nmental po int o f view, the pro ject
received the reco gnitio n level o f the Mediterranean Sustainable Buildings Go ld issued by the BDM Asso ciatio n
(http://po lebdm.eu/) fo llo wing the evaluatio n stage o f the pro ject design and implementatio n. Its strengths are a glo bal, cro ssreflectio n: üLa bio climatic design, including its perfect no rth-so uth o rientatio n (co mpact, high inertia, effective pro tectio n,
acco rding to so lar o rientatio n facto r, no so lar mask, ...), üLe visual co mfo rt ü The dimensio ned façade by façade with
dynamic thermal simulatio n thermal insulatio n üLa preservatio n and increase website Bio diversity, üLe cho ice o f the
co nstructio n pro duct with little o r no VOC, üLa awareness and training o f users, ü side ... Po wer engineering, Natura ENR
has wo n the call fo r pro jects PREBAT "10 0 best buildings in Lo w Energy PACA". These are also two buildings POSitive
Energy (BEPOS) acco rding to the requirements o f Negawatt appro ach: energy üSo briété, o f remo ving waste and unnecessary
üEfficacité energy needs, reducing energy co nsumptio n fo r a defined need renewable üEnergies by emplo ying energyefficient systems with reduced impact o n the enviro nment to do this, we initially achieved lo w energy co nsumptio n, by physical
calculatio n and no t by a single regulato ry calculatio n, limiting the energy co nsumptio n to an abso lute necessary. Then we set
up renewable energy (50 per kWp pho to vo ltaic building) to co mpensate all expenses co nsumptio n. This is indeed a real
"Po sitive Energy" co vering all uses, that is to say bo th regulato ry co nsumptio n (Heating, Co o ling, ECS, ventilatio n and
lighting) and all o ther co nsumptio n (elevato rs , IT, ....). Phase pro gram, it was co nsidered the po ssibility o f a maximum
o ccupancy o f the pro perty co mplex o f up to 240 peo ple thro ugho ut the year. This wo rst case helped calibrate the wider future
use.
De scripció n de la arquit e ct ura : The pro ject invo lves the co mpletio n o f two o ffice buildings that are o rganized alo ng a
so uthern slo pe (the slo pe varies between 12% and 5%) and the landscaping o f the plo t lo cated o n the So phia Antipo lis site
Mo ugins. The buildings lo cated in the natural slo pe o f the terrain are made acco rding to the same general principle: 1.A parking
DRC semi buried advantage o f the slo pe. The facades level Gro und flo o r, o ccupied by the parking lo t will be built with the
sto ne gabio ns which fills evo ke the ro cky stratificatio ns o f the gro und. 2.two flo o r co vered by a single ro o f slo pe facing so uth,
mo re o r less parallel to the natural slo pe that receives pho to vo ltaic panels to meet the requirement o f BEPOS in terms o f
energy pro ductio n. 3.The facades, iso lated fro m the o utside, are co ated with clay o r lazurés co ncrete cladding panels. 4. A
co ncrete structure co vered with a mineralizatio n, ho rizo ntal shading suppo rt will punctuate the so uth facade while pro viding
sun pro tectio n fo r windo ws. 5.En west and east facade, to meet a side so lar pro tectio n, so lar shading will also be
implemented. 6 .The gears will be embellished in cassette ho lder vegetated steel structure and pro vide users with large terrace
o verlo o king the surro unding pine fo rest. The access ro ad is an extensio n o f the existing track, the subject o f a winding ro ute to
fit better to the slo pe o f the terrain and to co pe with the existing plantatio ns. The will o f the pro ject is to maintain the current
quality o f the site linked to its visual o penness and walk. Thus no fence is planned fo r parcel bo undary. The water flo w o n
study fo reshado ws a mo st natural as po ssible and landscaped device; po nds, ditches, planting, slo pes, No ues ... The
po ro sity o f the pro gram in 2 buildings avo ids to o great breakthro ugh in the existing pine fo rest, and instead play a better
distributio n between pine fo rest and buildings.

Mat e riale s e co -dise ñado s : The building wished to be co py into its o peratio ns thro ugh the use o f materials, pro ducts
and systems that respect the enviro nment. This particularly invo lves the realizatio n o f a sustainable building scalable and
efficient to ensure sustainability and co mfo rt fo r future tenants and users. In o rder to enhance as much as po ssible lo cal
industries and reduce CO2 emissio ns fro m transpo rt, the cho ice o f pro ducts and materials will maximize pro duct available
in the PACA regio n. So me o f these are: - Co ncrete sailing (reducing transpo rt-related po llutio n and reducing co nstructio n
waste - gabio n walls, lo cal aesthetic elements - flo o r co atings and paints labeled and ensuring little o r no VOC emissio ns no tificatio n future users fo r their cho ice o f o ffice furniture (lo w to zero VOC and fo rmaldehyde)

Salud y co nf o rt : The integratio n o f all pro perty within its natural area has been the subject o f particular attentio n by the
strategy o f the gro up PERIAL well as the natural setting in which the transactio n is registered. A daylighting study was
co nducted in Phase pro gram to maximize co mfo rt parameters. The study sho ws better results than the regulatio n and
appro aching high reference levels HQE. The o peratio n was vo luntarily under densified. Wo rk premises and o ffer a clear

to daylight at each wo rkstatio n). The cho ice o f systems implemented to NATURA ENR has been custo mary in a quality
co ncern, taking into acco unt the specific enviro nmental characteristics o f the site (Mediterranean area) and by adapting the
architectural features o f the building. This requires: - Limitatio n o f heat lo ss (exterio r insulatio n, efficient windo ws, etc.) Effective ventilatio n (free co o ling) - Sealing o f the building 0 .6 Flight / h under 50 Pa (I4 <1) - The use o f so lar gain thro ugh

There are 8 units per building Daikin VRV Small, pro viding ho t and co ld, asso ciated with the
