A new elementary school is built in Grenoble with a 50% lower energy consumption level than the national average.
In 2007 the City of Grenoble drafted its Energy Action Plan, in line with the Metropolitan Climate Plan with the aim to cut by four GHG emissions by 2050. The objectives for 2020 are the EU’s “3×20”. As 80% of GHG emissions in Grenoble come from buildings, the City concentrates has concentrated its efforts on this sector in recent years. Thus, the City of Grenoble engaged itself to renew the 8.5 hectares of military barracks in the de Bonne district, including the new school.
The construction of a new school in de Bonne is linked to the renewal of this district launched in 2001. The school welcomes children who live in the de Bonne area as well as in the surrounding neighbourhoods. It is a 2 floors building with 2973 m2 of gross area, mixed concrete and a timber structure with external insulation, low emission glazes, with special focus on thermal bridges, a simple flow ventilation with pre-heated air, low consumption computers and a green roof.
Since the opening a dynamic thermal simulation, an infrared photography campaign and a consumption measurement campaign have been implemented. The final energy consumption is a little more than 50 kWh/m2 /year for heating.
