MORBIHAN ENERGIES carried out an experimental project in designing a building that produces for the electricity grid for its new head office in Vannes, Brittany. It is capable of varying its consumption electric power-especially in times of high demand-and can also store or reinject the renewable energy it produces. This project gave birth to the KERGRID building, featuring an area of 3,300 m², in compliance with the low carbon building and PassivHauss labels. A two-storey building made of wood and concrete, it has solar panels spread over the 850 m² of roof space and two micro wind turbines that provide electricity production for the area. EDF R&D (Research and Development) is supporting Morbihan Energies in optimising the operation of its building. In 2017, all-purpose final consumption amounted to 71 kWhfe/m² while solar production amounted to 110 MWh, 63% of which was self-used. All-direct emissions of greenhouse gases amounted to 4.3 kgeqCO2/m².year (14 TeqCO2/year). These figures confirm the high performance of this building.
