• The advent of the COVID-19 pandemic led to an economic crisis of the construction industry and to an increasing of energy consumption in the residential sector for all the world. These effects are added to those of climate change, requiring ever greater efficiency and sustain ability in buildings. The windows design and the windows replacement are critical aspects in the new and existing buildings, respectively. The proposed parametric analysis evaluates the effects of different window -system (thus glasses type and technology, frames and shields), conventional and innovative, on the total primary energy demand of an office, in different climatic locations. It is shown how the best configuration can be influenced by the window frame, the window orientation and the installation of internal or external shields. Considering also a smart-glass technology, the findings of this paper show that the approach adopted in a typical Mediterranean climate - where it is not enough to minimize only the energy need for heating or for cooling - is also valid in dominant heating or cooling climates. This study shows that an accurate design of windows can lead to significant savings in total primary energy. In particular, with reference to an office case study, the effect of solutions based on the solar gain control (low-e, selective glazing) was better than solutions based on the heat loss control (triple glazing), even in heating dominated climates. In Vienna and Split these configurations show the maximum total primary energy reduction, that is equal to \approx - 38\% and \approx -41\% . compared to the base case (\Delta \mathrm{E}_{\mathrm{P}}) , respectively.
