Immocrédit has recently put in place a new plan to save energy. This plan has been done in two parts: the first one was the modification of the entire lighting system of the 6300 and 6400 Auteuil. More energy efficient appliances have been put in place instead of the old one. The second part being the upgrade of controllers connected to the ventilation. These two measures allowed a great savings in the energy consumed by all tenants in these two buildings. A green choice for which all occupants of the two buildings now benefit daily.
