During the last 2-3 years, the interest in low energy and passive houses has increased significantly in Norway. More than 15 passive house projects incorporating more than 1000 apartments are currently in the planning phase, but only a few has so far been completed. This paper includes a description of the projects that have been completed and some of the projects that have come furthest in the planning. The projects are located in different climatic zones, ranging from the relatively mild coastal climate of Bergen to the cold inland climate of Lillehammer. The locations span from 58 to 70 degrees Northern latitude. The work is partly carried out within the framework of the European project ""Promotion of European Passive Houses"" (PEP), financed by the Energy Intelligent Europe programme (www.passivhouses.org).
