Based on the new energy performance limitations determinate by the Directive 2010/31/EU, the buildings become more energy efficient and the impact of the operational stages is reduced, increasing the relevance of the environmental and economic impact of the other life cycle stages. In addition, the energy refurbishment requirements are increasing, generating the need to integrate the life cycle methodology during the prioritization process between the different energy-efficient retrofitting strategies for buildings. However, despite the Life Cycle methodology has already been standardized, as buildings are extremely complex systems, a lot of studies usually apply some simplifications to reduce the time of the evaluation. Based on these simplifications and seeing that when talking about the energy renovation of an existing building, the main objective is focused on reducing its impact during its operational stage, are being generating various questions in relation to the need and added ...
