“…They are timber and concrete floors, pitched and flat roofs using hardwood, hollow heavy concrete, and adobe walls. In contradiction to the conventional studies where adobe and wood are mostly suggested building materials for the humid tropics, this study found that the indoors were more comfortable with hollow heavy concrete walls, concrete floors, and hardwood pitched roofs Cool roofs (reflective roofs with a high albedo and thermal emittance) seem to have more significant potential in terms of climate change adaptation along with energy efficiency, mitigating heat island effects, improving air quality and reducing heat wave impacts (Bureau of Energy Efficiency, 2011;Garg et al, 2016a;Garg et al, 2016b;Afshari, 2023;Bamdad, 2023). These roofs can be a better strategy in dealing with hotter environments, but further studies are required to understand their performance during winters when heating is the priority.…”

Buildings worldwide have evolved based on local resources and skills, evolving form and orientation to ensure a productive and comfortable indoor environment. Traditional habitations rely on passive climate-responsive mechanisms and physiological resilience. At the same time, contemporary buildings rely increasingly on active mechanisms for fine-tuned convenience and comfort. Those buildings are becoming less habitable due to climate change. This paper presents an overview of research into climate-responsive building adaptation, identifying various factors determining a building’s ability to regulate external climatic conditions in providing a habitable indoor environment. The review covers the ability of occupants to manage their thermal environment and adaptation mechanisms, including various adaptation strategies attributed to climate change. Besides a review of relevant research tools and methodologies, the paper also identifies future research challenges. Those challenges include but are not limited to evaluating climate classification provided by building standards given climate change, the need for region-specific climate-change vulnerability assessment of the built environment to develop specific adaptation strategies, a survey of vernacular structures to understand their inherent adaptation capacities, developing a framework to study building adaptation, etc. Thus, this review opens the possibility of further research in building adaptation.

Climate change has resulted in an increase of average outdoor temperature worldwide. With the rise of average outdoor temperature and unprecedented frequent heat waves, the demand for cooling systems in residential buildings has risen even in countries such as Belgium with moderate climates. However, there is a trade-off to consider when it comes to cooling. While active cooling methods can effectively maintain thermal comfort, they also come with excessive energy use in comparison to passive cooling techniques. However, passive cooling methods can lead to thermal discomfort and health issues during heat waves. To better understand this balancing act, this paper uses building energy simulation together with the measured current and accurately projected future climate data with high spatial resolution to investigate and quantify the potential for overheating in a selected residential representative building in the Flemish region of Belgium. Optimal solutions for renovation of the building are investigated including a variety of weather scenarios to account for climate change and to provide future-proof solutions. Results indicate that the renovation strategy is not affected by climate change for this case study. High insulation level with passive cooling strategy provided minimum energy use and acceptable summer overheating below 100 hours for this case study. Active cooling with medium and light renovation measures come with acceptable thermal comfort while also result in higher total energy use up to 53%.

The purpose of this research is to examine how data-driven dynamic urban communication affects the effectiveness and optimization of vital municipal services in a variety of contexts. Interestingly, waste management IoT sensors have an efficiency score of 9, which is remarkable and indicates the promise of data-driven approaches in this industry. An impressive 4.3 user satisfaction rating highlights how well these technologies are received. Additionally, data-driven communication techniques provide affordable options, as seen by their $2.5 service request cost, which highlights the possibility of more efficient resource allocation. This study offers strong proof that data-driven communication benefits both municipal service providers and people by increasing service consumption and lowering response times to around 5.2 minutes.
