Grenoble, France
The main metropolis of the French Alps with 530,000 inhabitants, at the junction of three Alpine valleys, is a city in a dense populated area surrounded by nature. Grenoble suffers from being a sink for pollution. The short term target is to reduce CO2 emissions by 14% until 2014 (compared to 2005), to reduce energy consumption per inhabitant by 2014 and to increase the share of renewable energy to attain a level of 14% of all energy consumed. Between 2004 and 2007, the emissions were reduced by 7%.
The CONCERTO approach
The RE supply will be improved through building for photovoltaic (PV) plants for a total of ~315 kWp, using solar thermal energy for domestic hot water on all new buildings, covering around 45% of the domestic hot water requirements and to increase biomass sources for the district heating system. In addition to this, the installation of 9 natural gas mini-CHP units for new buildings in de Bonne will cover half of the heating needs as well as 100% of the electricity needs.
About 12 eco-buildings are built in de Bonne with a minimum of 50% lower energy consumption level than the national average. 59 new dwellings are being built in La Viscose area in Echirolles.
A new elementary school is built in Grenoble with a 50% lower energy consumption level than the national average.
A total of 305 kWp connected to the grid of the photovoltaic plant. Photovoltaic panels are installed on four new buildings (2 office buildings; one shopping area and a stadium).
In de Bonne a training programme raises awareness and trains construction companies in energy performance issues.
Use of Renewable Energy Sources
• Geothermal energy
• Biomass
• Solar thermal panels
• Hydroelectric power stations
Low Carbon Technologies
• Mechanical ventilation with heat recovery /Doble flow ventilation
• District heating from biomass
• Insulation
• Monitoring and Targeting
• Combined Heat and Power (CHP) - conventional fuels
• Water and light efficient equipment
• Heat/cold storage
• Glazing windows
• Optimized lightning systems
• Heat pump
Highlights
At the shopping centre in de Bonne generation of electricity from renewable energy sources is enhanced through different national measures and incentives, for example direct and indirect financial and fiscal measures.
