In this study, a method for evaluating the energy demand and greenhouse gas emissions during the three life cycle stages production, use and end-of-life of a building or city quarter is presented and applied to different case studies. The main result is that from the life cycle energetic point of view, refurbishment to a high building standard is better than demolition and reconstruction to a similar standard under the condition that the structural condition of the building allows it. The analysis includes different climatic conditions and their high influence on the life cycle energy demand and greenhouse gas emissions.     «
