This project has been carried out for the ALEC (Agence Locale de l'Energie et du Climat) of Grenoble urban area, a French energy and climate agency. It has been composed of several missions, all related to energy management in residential buildings. First, an annual energy use assessment have been conducted for two different building samples:  the eco-district of De Bonne in Grenoble and a sample of about 25 social housing buildings over the region. These two assessments showed that the average energy performance of newly built buildings is improving every year, notably under the stimulation of innovative projects such as De Bonne. Then, a more precise follow-up of construction and renovation social housing projects enabled to learn more about how to maintain energy facilities and to detect some common technical issues. The global conclusion of this project is that, although buildings are better designed today, energy performance remains fragile notably during construction and operation. To cope with that, some solutions exist and should be more systematically applied in future construction or renovation projects.
