Special Issue Information

Dear Colleagues,

Urban areas around the world are increasingly vulnerable to climate change, particularly heat waves, which have a significant impact on the well-being and health of urban populations due to increasing thermal discomfort.

This Special Issue focuses on improving climate resilience in urban environments through cutting-edge research and innovative solutions characterized by interdisciplinary approaches that integrate climate science, urban planning, engineering, public health and environmental sustainability.

This collection of scientific articles aims to promote advanced technologies; emphasize strategies to mitigate the effects of heat waves; improve thermal comfort. Its scope includes innovative technologies for monitoring and mitigating urban overheating, nature-based solutions, and green infrastructure to enhance urban cooling. It also covers urban design and planning strategies aimed at improving thermal comfort, climate-responsive building designs and materials, and the use of remote sensing and data analytics, including AI and big data analysis, for urban climate resilience. Public health interventions and policies addressing heat-related risks are also welcome, along with case studies and best practices from cities worldwide. This Special Issue further highlights the socio-economic and environmental impacts of heat waves on urban populations and presents adaptation and mitigation strategies for future urban climate scenarios.

It provides a platform for researchers, practitioners, and policymakers to share their visions, innovations, and experiences in building climate-resilient urban areas. By disseminating knowledge on emerging research, technologies, and effective strategies, it aims to contribute to the development of more sustainable, livable, and resilient cities. Submissions of original research articles, reviews, case studies, and technical notes are encouraged to address these pressing urban climate challenges.

Thank you, and we hope you consider contributing to this Special Issue.

Passive evaporative cooling technology using the building envelope is a crucial measure to mitigate the urban heat island effect. This study aims to enhance the cooling efficiency of the surface of enclosure structures by utilizing volcanic ash, potassium–sodium stone powder, and silica-based mesoporous oxide (SMO) as primary materials. These components are incorporated into the ceramic brick production process to create innovative humidity-controlling ceramic bricks (HCCTs). This study extensively investigates the impact of SMO and the amount of applied glaze on the physical and mechanical characteristics of these HCCTs. Additionally, it examines the water absorption and evaporative cooling properties of the studied materials under optimal substitution conditions. Numerical calculations are used to determine the heat and moisture transfer properties of HCCTs. The results indicate that incorporating 2% SMO and applying 70 g/m2 of glaze results in a moisture absorption capacity of 385 g/m2 and a moisture discharge capacity of 370 g/m2. These conditions also yield a notable flexural strength of 15.2 MPa. Importantly, the HCCTs exhibit significantly enhanced capillary water absorption and water retention capabilities. Increased water absorption reduces surface temperature by 2–3 °C, maintaining the evaporative cooling effect for 20 to 30 h. It is also found that the temperature of HCCTs decreases linearly with increasing water content and porosity, while the temperature difference gradually decreases with thickness. Water migration in HCCTs with greater thickness is notably influenced by gravity, with water moving from top to bottom. Therefore, it is recommended that brick thickness does not exceed 15 mm.
