// Description
The SMED13 has built its headquarters in the to wn o f Miramas. This is an o ffice building with a flo o r space o f 1,10 0 m² to
ho use SMED13 emplo yees and delegates.
Lo cated o n the plaine du Crau, the land with a surface o f 2520 m², straddles the municipalities o f Miramas and Grans. It is part
o f the Clé Ouest ZAC, managed by the EPAD Ouest Pro vence
The land do esn't have neither tree no r co nstructio n.
The building was built in the so uth field, in the to wn o f Miramas, in seismic zo ne 3. This mo ve preserves much o f the
undevelo ped land.

De script io n archit e ct urale : On the site o f interventio n:
Lo catio n marked by a ro w o f majestic plane trees, a riparian fo rest that acco mpanies the main channel draining the pro perty,
the co urt o f Mas des Mo lières, remarkable fo r its scale and quietude, a field, always green, where the pro ject is implanted.
These elements, which, o n their o wn, co nstitute the site, are essential. And even they are sufficient. It is therefo re appro priate to
identify the invasive scrub, to clean them, to strengthen them, to develo p them by eliminating anything that night to a stro ng
reading o f this landscape. It sho uld also make them live to gether again. This is the meaning o f the interventio ns that we
suggest in the site plan, including o pening the field to the Co urt, linking areas, releasing the views.
Co ncerning the co ntext and implementatio n o n the gro und:
In this co ntext, o ur pro ject restricts its fo o tprint and frees the land. By frugality to save the land, in advance, to clear the
po ssibility o f a further extensio n, but abo ve all to leave this field that is the place, its leadership and integrity. A parking lane and
pedestrian walkway, clearly sto p the bo undary between rural and urban. The field o f green grass is free. But it is no t accessible.
The pro ject do vetails with this divide, delicately placed o n the gro und, reducing any impact o n the field, flo ating like a great ship
do cked, pro pped against plane alignment.
Co ncerning the questio n o f the image:
After insertio n into the site, the pro ject must meet the needs o f SMED 13 in terms o f image. A new institutio n, which manages,
with access to energy issues o f impo rtance to o ur co mmo n future, and that claims o f this so me visibility, identity, and
affirmatio n o f a presence in a place that is yet to create. Our team has wo rked hard to ensure this exceptio nal building energy
perfo rmance that can create, by example, the legitimacy o f SMED. In fact, it is the vo lume o f the pro ject, the expressio n o f its
facades, the texture o f their skin, which express the strength, the energy, the dynamism in this institutio n. Pulsed po wer in the
idea o f the Earth as energy issues are implicit in them.

De script io n:
The active flo o r system is an active heat sto rage system which o perates the building mass
co ncrete fo r unifo rm ro o m temperature thro ugh a netwo rk o f tubes installed o n metal mesh and
inco rpo rated into the bo dy o f the bo o k. The water circulates in tubes embedded in the co ncrete
slab that accumulates the heat lo ads o f the ro o m and the external inputs. The co ncrete mass is
then co nsidered as a reservo ir o f warmth o r co o lness. Its o peratio n requires lo w temperatures,
can significantly reduce energy co nsumptio n and increase thermal co mfo rt. On the Pro ject
SMED 13, the heating / co o ling system with active flo o r is used with water circulatio n o f the web. Two ho les, o ne pump and
o ne reinjectio n were carried o ut no rth and so uth o f the building, in the flo w directio n o f the web. The advantages o f the system:
- transmissio n co mfo rt with a pro gram based mainly o n radiatio n - (resulting temperature, no t air temperature)
- Maintenance co st Maintenance zero (the maintenance and service fo cus so lely o n pro ductio n and regulatio n per facade)
- Operatio n at lo w delta T to set up a pro ductio n o f heating with a heat pump water / water with very high efficiency (COP>6 )
- Clipping po wers to pro duce ho t and co ld
- ho using Timeliness This system is also used in active walls in two sails o f the building's atrium.
