Analysing the climate in which buildings are located is the first step towards high-efficiency design, and today it is no longer possible to ignore impending climate change. This study has provided a worldwide picture of how comfort conditions inside a building can change as external climatic conditions change. For the first time, a building is tested worldwide over a long-term period, and not just in a specific climate or a small group of climates. Several cities homogeneously distributed around the world were selected, covering all climates of the Köppen-Geiger classification. A hypothetical building was implemented with the Termolog Epix 11 software in order to monitor the operative temperature (TOP) in free-floating mode on an hourly basis and test its temperature variations in the short, medium and long term. The percentage values of the hours when the TOP is in a comfort or discomfort conditions were compared for all configurations. The results showed that the comfort conditions vary with the climate. Climate zone A displayed for most subclimates high TOP values. Climate zone B showed an irregular trend, from 2020 to 2080 the hours when TOPs fall below 20 °C decreased in most locations. Climate zone C included areas where TOPs are mostly in the comfort range. Some sub-climates in zone D show very cold climates, with an average of about 15–20% of the annual hours in the comfort zone in 2020, then increasing slightly by a few percentage points in 2080. © 2021 Elsevier LtdElsevier Ltd2021Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/13192https://doi.org/10.1016/j.jobe.2021.1030572352-7102enJournal of Building Engineeringinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13192
