cRRescendo Site Ajaccio

Many cities have urban fabric ripe for renewal. Ajaccio, the regional capital of Corsica, is no exception. Taking buildings from the 1960s and making them more energy efficient is one of the main challenges being tackled by this Concerto-Project. An added challenge is the renovation of buildings in Ajaccio's historic centre. Double-glazing with thermo-coating is being installed in fifty buildings in the protected city centre. These buildings are among 250 being re-glazed in this way.

SESAC Site Grenoble

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%.

E2REBUILD Site Voiron

The Voiron demonstration site of E2REBUILD project is a multi-storey building in the department of Isère. The building was made of concrete with no insulation, it had natural ventilation and the windows were first-generation PVC double-glazing 4-6-4. All dwellings had an individual gas boiler for domestic hot water production, but each dwelling had its own different heat production – either electric heaters (ca. 29 dwellings with an energy demand of 529 kWh/m² year) or fossil fuel boilers (c. 43 dwellings with an energy demand of 202 kWh/m² year).
