Four action types were defined:
- improve the performance of buildings
- optimize the contracts so that the operating companies are motivated in energy savings
- establish energy management
- educate and train users and managers.
Energy consumption was reduced from ep 240 kWh / m² / year in 2009 to 192 kWh ep / m² / year in 2011 (25% reduction). Two buildings were renovated to low energy levels. The renovation of another building is under study, with the goal to reach a performance of 41 kWh of primary energy / m² / year - at a reasonable cost. Which will thus make this building a pilot project transferable to other similar buildings.
