SDEM56 Headquarters:
Syndicat des Energies Departmental Morbihan is a building of 3300 m² with a storage system powered by green energy with 850 m² of solar panels and two wind turbines. Energetically efficient, labeled "Passiv Hauss' with a theoretical consumption of less than 15 kWh/m² per year, this building is built on a plot of about 1.5 ha corresponding to a part of the land held by the ASPTT, west of the city of Vannes slightly south of the RN 165 in sector Fétan Blay.
Sustainable development approach of the project owner
The departmental union of energy in Morbihan (SDEM) and Schneider Electric innovates in Vannes. They signed a deal to set up a first energy storage and management systemin France: Kergrid. Kergrid is a network of intelligent electricity distribution implemented in the future premises of SDEM. Objective: "To adapt to the constraints of the electric britton network." This is meant to anticipate and control energy expenditure, particularly during peak consumption: by automating the management and storage. "The building will include the ability to operate autonomously (2 hours). "This experiment is bound to be" duplicated and repeated in other buildings. "Architectural description
This building was designed by the architecture agency Arcau in Vannes. It is equipped with:- 850 square meters of photovoltaic panels integrated roof
- Energy Storage System (lithium batteries) for partial autonomy of the building during peak periods of electrical network
- Heat generation by geothermal heat pump- Passive Cooling via circulators geothermal / Ventilation night by CTA turbofan
- Breezes fixed sun exterior vertical or overhanging roofs with exposure facades
Lighting by low consumption lamps and LED / presence detectors
Triple little emissive glazing and joinery timber
Daylighting circulations
