The SMED13 has built its headquarters in the town of Miramas. This is an office building with a floor space of 1,100 m² to house SMED13 employees and delegates.
Located on the plaine du Crau, the land with a surface of 2520 m², straddles the municipalities of Miramas and Grans. It is part of the Clé Ouest ZAC, managed by the EPAD Ouest Provence
The land doesn't have neither tree nor construction.
The building was built in the south field, in the town of Miramas, in seismic zone 3. This move preserves much of the undeveloped land.
Sustainable development approach of the project owner
Performance and image variety of possible: Reduced requirements, high performance envelope, significant solar gain, low temperature emissions, PAC water / water cooling on water, photovoltaic, solar thermal, wind, CNG station, taking electric vehicles.Architectural description
On the site of intervention:Location marked by a row of majestic plane trees, a riparian forest that accompanies the main channel draining the property, the court of Mas des Molières, remarkable for its scale and quietude, a field, always green, where the project is implanted.
These elements, which, on their own, constitute the site, are essential. And even they are sufficient. It is therefore appropriate to identify the invasive scrub, to clean them, to strengthen them, to develop them by eliminating anything that night to a strong reading of this landscape. It should also make them live together again. This is the meaning of the interventions that we suggest in the site plan, including opening the field to the Court, linking areas, releasing the views.
Concerning the context and implementation on the ground:
In this context, our project restricts its footprint and frees the land. By frugality to save the land, in advance, to clear the possibility of a further extension, but above all to leave this field that is the place, its leadership and integrity. A parking lane and pedestrian walkway, clearly stop the boundary between rural and urban. The field of green grass is free. But it is not accessible.
The project dovetails with this divide, delicately placed on the ground, reducing any impact on the field, floating like a great ship docked, propped against plane alignment.
Concerning the question of the image:
After insertion into the site, the project must meet the needs of SMED 13 in terms of image. A new institution, which manages, with access to energy issues of importance to our common future, and that claims of this some visibility, identity, and affirmation of a presence in a place that is yet to create. Our team has worked hard to ensure this exceptional building energy performance that can create, by example, the legitimacy of SMED. In fact, it is the volume of the project, the expression of its facades, the texture of their skin, which express the strength, the energy, the dynamism in this institution. Pulsed power in the idea of the Earth as energy issues are implicit in them.

Ecocem is a granulated slag ground blast furnace (smelting steel manufacturing waste) and used in the concrete composition in substitution of Portland cement. • Enables the reduction of CO2 incorporated. • CO2 emissions from the production of Ecocem are 40 times lower than in the production of Portland cement. • Concrete Ecocem reduced heat absorption
drying time slightly longer and maximum hardness compared to traditional concrete.

The active floor system is an active heat storage system which operates the building mass concrete for uniform room temperature through a network of tubes installed on metal mesh and incorporated into the body of the book. The water circulates in tubes embedded in the concrete slab that accumulates the heat loads of the room and the external inputs. The concrete mass is then considered as a reservoir of warmth or coolness. Its operation requires low temperatures, can significantly reduce energy consumption and increase thermal comfort. On the Project SMED 13, the heating / cooling system with active floor is used with water circulation of the web. Two holes, one pump and one reinjection were carried out north and south of the building, in the flow direction of the web. The advantages of the system:
- transmission comfort with a program based mainly on radiation - (resulting temperature, not air temperature)
- Maintenance cost Maintenance zero (the maintenance and service focus solely on production and regulation per facade)
- Operation at low delta T to set up a production of heating with a heat pump water / water with very high efficiency (COP>6)
- Clipping powers to produce hot and cold
- housing Timeliness This system is also used in active walls in two sails of the building's atrium.
The usual users sick because of air conditioning, are no longer with the active slab.
