“…Following the methodological framework included in Figure 1 and in line with other studies found in the literature [46,47], after having performed the monitoring campaign to determine the thermal characteristics of the building envelope, the selected building was modelled in DesignBuilder version 6.0.1, and dynamic energy simulations were performed in EnergyPlus version 9.2. In order to optimize the accuracy and the computational resources required by EnergyPlus, a heat balance algorithm using the Conduction Transfer Function (CTF) was used.…”

User behaviour can significantly affect indoor thermal comfort conditions, as well as energy consumption, especially in existing buildings with high thermal masses where natural cross ventilation is the main strategy to reduce cooling loads. The aims of this paper were: (i) to compare how behavioural changes evaluated by means of rule-based and stochastic models lead to changes in indoor thermal comfort levels, and (ii) to define the patterns of indoor thermal comfort in historic residential buildings in future scenarios. To this end, a historic building located in Molfetta (Southern Italy) was analysed using a dynamic energy simulation engine in five weather scenarios (Typical Meteorological Year, current extreme weather file 2018, predicted weather files for 2020, 2050, and 2080 generated by morphing method), and stochastic and rule-based models for window openings were adopted and compared. The results showed that the stochastic model was more accurate than the rule-based one, resulting in a reduction of discomfort conditions during the summer period between 30% and 50% in all climate scenarios. However, although the differences between predicted discomfort levels using rule-based and stochastic models tended to increase, discomfort levels still appeared to be not acceptable in the 2050 and 2080 scenarios due to the rising temperature driven by climate change.

“…Numerous studies have examined the risk of overheating and indoor thermal comfort in different types of buildings during heatwaves, with some focusing on specific regions and employing different analysis methods. Ozarisoy [34] studied thermal comfort conditions in a prototype terraced building located in Watford, UK, from May to September 2018. It was found that indoor operative temperatures remain relatively high during the heatwaves, ranging from 26.5 C to 32.5 C. The situation is worse in the bedrooms on the first floor, where indoor operative temperatures exceed EN 15251 Category II upper limit for 15% of the hours.…”

As heat stress intensifies across Europe, the escalating use of air conditioning poses environmental, equity, and reliability concerns. Macro-quantitative performance analyses of passive cooling techniques (PCTs) are lacking, hindering the development of thermal resilience policies. Employing an extreme value bias approach, this study investigates the capacity of vernacular PCTs to satisfy thermal comfort and safety standards in current and projected European climates, demonstrating the substantial contribution they can make towards meeting cooling demand until the end of the century. Results show that such PCTs could still fulfill 90% of cooling demand for comfort in at least 83.30% of cooling-demanding regions across Europe over the 2070-2100 period (including 82.82% of Mediterranean regions), compared to 99.93% over the 2010-2040 period. While occasionally insufficient for comfort, PCTs could still play a crucial role in safeguarding occupants, meeting over 90% of the cooling demand for safety during extreme temperature and humidity events in at least 84.28% of cooling-demanding regions of Europe (including 75.05% of Mediterranean regions) over the 2070-2100 period (compared to 99.68% over the 2010-2040 period).
