摘要：AbstractNowadays the sustainability is one of the primary concerns worldwide, especially in the construction industry, taking into account that the buildings have a major impact on the overall energy use and greenhouse gases emissions. There are many studies focusing on particular aspects of the topic, but a holistic, interdisciplinary and long-term approach is needed in order to reconcile the competitive objectives. Starting from a literature research, the authors have formulated a decision making algorithm aiming to respond to professionals needs to apply a structured model in their daily activities. In the second part it is presented how this model can be applied, using a practical case-study – a building in the renovation phase, emphasizing how to optimize the project even when dealing with conflicting criteria.
