Here we have most of the iconic Paris elements. The Louvre, at the center, is a large museum that has indeed a sizeable energy use as it receives thousands of visitors a year and requires strict conservation measures for its art treasures. On the central- nothern part the Opera Garnier is another big energy user, also surrounded by massive buildings. The Musée d’Orsay or the Centre Pompidou are also visible, but the biggest spot is the Grand Palais, at the begining of the Champs Elysees, to the west. A giant greenhouse, it is a relevant building in the urban landscape, and also potentially a big energy and ressources user. In this dense area, in which streets seem carved out of a giant block, the river Seine and the Tuileries gardens are the biggest open spaces, linked to the begining of the Champs Elysées and the Esplanade des Invalides.
