Abstract: This research is focused on the impact that outdated climate files have on the energy simulation of a generic residential building model located in semi-arid regions. Two representative residential buildings have been modelled with TRNSYS software, according to the local characteristics. To evaluate the annual thermal demands, seasonal temperature set-points have been fixed. Then, a parametric evaluation has been developed considering different Spanish building regulations, two boundary conditions and three climate years (one long-term experimental file and two synthetic representative files). The comparison between them gives an idea of how the climate change modifies the patterns of the building energy performance.
