This master thesis is a case study of a newly built single-family house located in Ry (Denmark). The aim is to evaluate technologies’ resilience to over-heating. The technologies include natural ventilation, phase change materials and shading. The investigation is performed using adaptive comfort model and future weather data up to the year 2100. The following documents were used as the re-search basis: The Danish Building Regulations 2018 and DS/EN 15251. DesignBuilder was used for building modelling. Meteonorm and CCWorldWeatherGen were used for the assessment of future extreme weather events. The resilience of the technologies was evaluated using POR and hours above 27 °C and 28 °C. Additionally the robustness of technologies against occupancy, climate change and the technology-related uncertainties was investigated. The results of the investigation revealed that all the technologies show very low POR values, below 5%. PCM and natural ventilation were not robust against climate change. When it comes to occupant density, the combination of technologies showed the highest robustness. All the technologies were robust against the technology, weather and occupational time related uncertainties.
