Appro ccio de l pro prie t ario alla so st e nibilit à e ne rge t ica : A urban develo pment pro cess and co nstructio n which is
part o f a sustainable develo pment appro ach can meet this do uble urgency o f co ntro lling the enviro nmental impact o f buildings
at the lo cal, regio nal and glo bal o n the o ne hand and perfo rming spaces life mo re co mfo rtable and healthier o n the o ther
hand. And this is especially the lo catio n and o rientatio n o f buildings o n the site which define the quality o f this respo nse, since
they pro vide no extra co st, satisfacto ry so lutio ns to this pro blem:
- A minimizing earthwo rks, and subsequently a limitatio n o f nuisance, po llutio n, disruptio n o f the natural enviro nment and the
co sts incurred.
- The Building is po sed lightly o n the land fo llo wing its to po graphy
- No site evacuatio n was required, all the cuttings were reused;
- Bypassing all the trees and preserving their ro o t system thro ugh fo undatio ns limiting excavatio n;
- Minimum waterpro o fing o f the field by the establishment o f mo re than 50 0 m² o f green ro o fs planted with plants taken fro m
the site, creating a car park co nsisting o f a dirt / sto ne co mplex (o r grass / gravel) and car traffic lanes defined by o nly 2 treads
co ncrete separated by a stabilized vegetated area;
- A Minimizing direct so lar gain o n facades, o ptimizing the po tential o f natural ventilatio n and maximum use o f natural light
depo sit, three issues that have a direct impact o n user co mfo rt and energy co nsumptio n;
- The Creatio n o f atmo spheres and quality o f views, a harmo nio us dialo gue with the natural enviro nment, limiting harmful
interference to the neighbo rho o d and the site. The headquarters o f the Natio nal Park o f Guadelo upe is thus to “land” with
respect fo r the site o n the gro und level curves between existing trees preserved. The few necessary earthwo rks are treated
balanced cut and fill.
De scrizio ne archit e t t o nica : - The sweet integratio n o f the building and o n the ho st site
- The preservatio n o f the diversity o f enviro nments and remarkable trees o f the site.
- The Opening and transparency o f the building as an attractio n to the kno wledge o f nature.
- The Quality o f the interio r spaces fo stering relatio nships, exchanges and co nviviality in a place to wo rk, co mfo rtable and

- The architectural transitio n between this place o n the edge o f the city and the natural area o f the park and So ufriere.
- A Fluid and readable fo r all o perating upo n entry Headquarters
- An exemplary in co ntro lling energy co nsumptio n and co nserving natural reso urces

Optimizatio n o f natural ventilatio n after sunscreen limiting external heat gains, thermal co mfo rt thro ugho ut the building, is
created by the breakdo wn o f lo cal enabling:
- firstly, to evacuate the internal lo ads which have previo usly been minimized;
- Seco ndly, to create an air speed o f the o ccupant can reduce up to 4 ° C the temperature felt by the latter with an air speed
inside the building and o n the o ccupier o f the o rder o f 1 m / s.
Excellent capacity fo r natural ventilatio n o f buildings is permitted by the design o f the master plan :
- which o utlines the best building to capture the prevailing winds;
- Which includes tall circulatio n spaces with o ptimal natural ventilatio n po sitio ns o f input-o utput, and scalability o f the do o rs
(frames ventilatio n) leading to the ability to co ntro l the directio nal flo w and air speeds.
In terms o f design: the po ro sity (drilling rate) o f the facade do wnwind air flo w, less efficient (thermal day breeze) is increased
minimally to values co nsistent with tho se specificatio ns ECODOM lo ads and allo w fo r circulatio n ho mo geneo us air and a
venturi effect. Fo r perio ds witho ut wind o r when the wind speed will be insufficient to ensure thermal co mfo rt, it may be
o btained by means o f air ceiling brewers. These ceiling fans create an air speed o f abo ut 0 .5 m / s in the ro o ms where they
are installed and may induce impro vement felt co mfo rtable aro und 2 ° C.
In the first year o f o peratio n, the perfo rmance ratio o f the so lar generato r is higher than average (11%) o f the mo nito red
facilities in Guadelo upe
So lut io ns e nhancing nat ure f re e gains : The design o f effective sun pro tectio n is essential to create co mfo rt in a
building that is no t air co nditio ned, this sunscreen also minimizing co o ling requirements o f buildings which are air
co nditio nned.

The eco -management pro cess o n drinking water was identical, in metho do lo gical terms, to the o verall co nceptual appro ach
ado pted by the team fo r the pro ject design and especially fo r the management o f o ther fluids including energy:
- So briety in the use o f water ie o verall design o f facilities and green spaces (patio , green ro o f ...) minimizing the drinking
water needs and enco uraging users to ratio nal and reaso nable use o f this water;
- Efficiency in the use o f water ie designing distributio n systems and terminals minimizing, fo r a given service, co ld water
co nsumptio n and ho t water;
- Ratio nal design o f inland water netwo rks with pressure relief valves (max 3 bar), a minimizatio n o f dead legs and lengths
o f terminal antennas, glo bal o ptimizatio n pathways enabling: to save water by reducing rates (co ntro lled pressure); water
savings by presence detectio n fo r each withdrawal po int (except the co mmo n kitchen);
- Design o f water terminals efficient po table use: To ilets do uble speed, ro bust and easy to use, with integrated signage
speed max 3/6 liters; Terminals sho wer and sinks with mo dular flo w aerato rs with Max 8 l / min; Minimizing Legio nella risk
thro ugh the use o f electro nic faucets with auto matic o pening 45 s after 24 ho urs o f no n-use thus preventing the
develo pment o f bacteria.
- Selectio n o f lo cal plant species o f trees and shrubs with very lo w water needs. The species selected are all no n-allergenic
He alt h & co m f o rt : The main pillars o f co mfo rt fo r the users o f the premises are:
- Optimal natural ventilatio n but anytime manageable and assisted by lo w po wer co nsumptio n devices (ceiling fans ceiling)
- An o ptimized natural lighting
- Spaces o pen o nto the preserved o r reco nstructed nature
- distant views o mnipresent sea, the Caribbean mo untains but also the mature gardens.
To do this:
- All buildings o f bo dies 6 meters deep at mo st to allo w penetratio n o f natural light unifo rmly
- All o ffices have a wide o pen fro ntage o n the direct sunlight (no rth o r so uth facade) and a seco nd day o f the patio o r the
lighted co rrido rs,
- All o ffices are in direct thro ugh-ventilatio n,
- prevailing winds are drained into the "bo ttleneck" o f patio creating a pull facto r co nductive to ventilatio n that advertises the
freshness created by plantatio ns in all o ffices.
- The friendly meeting places are present thro ugho ut the circulatio ns. These spaces are wo rking o n the o utside and the
treatment o f their fro nt raw wo o d trellis pro vides permanent ventilatio n while letting in a gentler filtered light.

De scrizio ne :
Lo cal wo o d was used fo r all claustras gates that clo se the building. This is a perfo rmance
because the wo o d industry do es no t exist in Guadelo upe. Indeed, in o rder to succeed, we had
to use the o nly wo o d that still co mes fro m the fo rest and used to make timber pro pping in
co nstructio n. To do so , an agreement with NFB (Natio nal Fo restry Bo ard) was passed so they
designate the parcel can be harvested. The trunks o f yo ung trees are used as raw. The principle
is to replace them if they are degraded. Presently, o ne o f the species (white gum tree the mo re
tender) ho sts many “Vo nvo n” (Xylo co pa mardax, fat bumblebee) to the delight o f manager who
sees and bio diversity invade even his building. Ano ther advantage is the light that is created inside o f the building is screened,
so ft, like a wo o d.

The client was very pleased o f this pro duct because its enviro nmental appro ach had suffered fro m the failure to use lo cal

This reference building in Guadelo upe is emblematic o f a search fo r co mfo rt and minimizing enviro nmental impacts at lo wer
o verall co st. It was designed in an Enviro nmental Quality appro ach Building (QEB) in tro pical enviro nments, which relies
heavily o n a bio climatic design o f the architectural pro ject.
By explo iting the natural reso urces o f the site (climate, to po graphy) and fully respecting the natural enviro nment (existing
remarkable trees, minimizing cut and fill, landscaped entry, o ptimized o rientatio n ...) serving a bio climatic o peratio n mo de (to
