Although recent studies demonstrate the importance of including the Embodied Energy (EE) in building analysis, only the Operational Energy (OE) is currently taken into account in building energy demand calculation method. In particular, the EE plays an important role in tall buildings evaluation, because the energy demand increases with building height. Aim of this study was to assess the Embodied Energy in evaluation of different types of tall building façade systems performances along with the Operational Energy, pointing out the importance of taking into account both these aspects. Within the research activity here presented, 8 glazed envelope typologies, in 5 different climate zones, have been evaluated.
