Traditionally, green design considers climate as a fixed property of a specific place. Nevertheless, recent changes demonstrate that this vision has to be reversed, considering climate a time-dependent parameter. This paper hybridises climatology and bioclimatic design underlining, thanks to the usage of a very recent high resolution climate reanalysis database (ERA5-Land), the impact that climate changes have on short-term periods, adopting well known building climate-related indicators. European maps are drawn considering degree-days variations (from 1981-95 to 2004-18), while typical mean 24-hour monthly days and bioclimatic charts are adopted for a limited number of locations. Results support the need to adopt climate data time variations during design phases.
