Urban environment

According to the Concarneau PLU, the area of the project is classified in zone 1AUi, intended to receive handicraft, industrial and commercial activities incompatible with the habitat. The location of the project in this area leads to special requirements, particularly for stormwater management. Moreover, an educational garden has been designed with the aim of being a place of information and advice to the realization of a garden. Created by Anne Lavorel, a trégunoise landscaper, he is an assistant to imagine his garden, to choose and associate plants, to think about landscaping ... Six illustrated panels are available for free reading and provide valuable tips for designing an ecological and sustainable garden.

Product category :

The function of the bioclimatic facade is to preheat the fresh air to be brought to the premises. The new air
Is heated in the double skin before being sucked in by the extraction fans. In summer, the canopy has on the exterior façade openings that can be opened manually to evacuate the calories directly to the outside and thus avoid overheating.

The air intake is provided by ventilation openings or grilles in all the premises. Stale air is extracted through extraction grilles located on the ceiling of the premises. The extraction grids are then connected to an extraction box by a set of steel ducts running through the false ceilings. Extraction is carried out by natural pulling thanks to the mechanical extractors placed on the roof. In case of insufficient flow in wind too low, a mechanical device allows to increase the flow.

Construction and exploitation costs

• Cost of studies : 193 060 €
• Total cost of the building : 1 656 617 €

Water management

A 10 m3 tank was installed. The recovered water is used for the maintenance of green spaces, the feeding of the hose of the sanitary ware and the supply of the faucets of the drawings of the workshops and technical rooms.

Indoor Air quality

Air renewal is the main action to ensure indoor air quality. The flows used are those of the   Ventilation single flow, they work according to the schedules of occupation of the building. For offices, the flow rates are 5 m3 / h per office, 150 m3 / h for the meeting room, 270 m3 / h for the conference room and the whole ecopole and 80 m3 / h for the whole Of the toilets.

Comfort

Health & comfort : In the office area: LED lighting gives an illuminating power of 8 W / m². Management is at   Manual control with dimming of brightness. In the ecopole part, the management is automatic with variation according to the threshold of natural light. The LED lighting has a thermal power of 6 W / m². In the other rooms, the LED lighting emits an illuminating power of 6 W / m² and its management is detection of presence and absence and according to a timer.

Calculated thermal comfort : La simulation thermique dynamique (STD) a permis de vérifier que la puissance disponible par le rafraichissement du géo-cooling était suffisante pour éviter tout problème de surchauffe dans les bureaux. L’objectif du référentiel technique PEQA concernant

Measured thermal comfort : Pour assurer le confort thermique d'hiver, l’accent a été mis sur la performance de l'enveloppe (Ubât estimé à 0,33 W/m².K sur l'ensemble du bâtiment par la STD), l’intégration d’une serre bioclimatique et d’mur capteur permettant de préchauffer l'air ent

Acoustic comfort : An acoustic notice in the project phase has been drafted in order to comply with the regulations in force for this type of project and to see proposals for solutions to be implemented.

Life Cycle Analysis

Eco-design material : Eco-construction made of materials such as wood-hemp wool as well as a wooden frame.
