“…Moreover, the categorization through urban typological analysis can help identify areas that need improvement or revitalization. By analyzing the different categories of urban elements, it is possible to identify areas that lack infrastructure, public spaces, or green elements and develop strategies to fill these gaps [34]. In the case of Ferencváros, typological study revealed the municipality's renovation strategy, which involved prioritizing the renovation or replacement of existing urban sub-elements to achieve a more cohesive urban fabric.…”

In response to the imperative to enhance urban structures for global sustainability and improved quality of life, the European Union has diligently established parameters and policies fostering urban cohesion and territorial integration. Embracing the guidelines conceived by the European Commission, this research presents a case study examining morphological conditions in the IX District of Budapest, Hungary—a strategically chosen area undergoing renovation. The primary goals of the intervention are to address social and spatial segregation, enhance urban performance, and promote global resilience. Employing a Typological Survey methodology, an in-depth assessment was conducted and translated into a Geographic Information System (GIS) database. Consequently, the morphological analysis successfully identified five distinct types of elements composing the urban structure of the studied area. This analysis revealed a highly heterogeneous constitution characterized by dynamic and continuous changes, reflecting the evolving nature of the urban landscape. Findings indicate noteworthy improvements in the performance and quality of public spaces while preserving the historical morphological characteristics that have long defined this area and its urban landscape.

“…Increasing urban water bodies and blue infrastructures promotes evaporative cooling and reduces urban heat island effects (Krüger, 2021 ; Sharma et al 2022 ). Yet, these infrastructures would better be carefully designed and fitted into city planning to maximum the effectiveness (Kolokotsa et al 2022 ). Infrastructural modifications including building materials to increase surface albedo and decrease heat absorption are also mitigation measures (Krüger, 2021 ; Sharma et al 2022 ).…”

Visits to the accident and emergency department in hot season of a city with subtropical climate: association with heat stress and related meteorological variables

Background Literature reporting the association between heat stress defined by universal thermal climate index (UTCI) and emergency department visits is mainly conducted in Europe. This study aimed to investigate the association between heat stress, as defined by the UTCI, and visits to the accident and emergency department (AED) in Hong Kong, which represents a subtropical climate region. Methods A retrospective study involving 13,438,846 AED visits in the public sector from May 2000 to September 2016, excluding 2003 and 2009, was conducted in Hong Kong. Age-sex-specific ANCOVA models of daily AED rates on heat stress and prolonged heat stress, adjusting for air quality, prolonged poor air quality, typhoon, rainstorm, year, day of the week, public holiday, summer vacation, and fee charging, were used. Results On a day with strong heat stress (32.1 °C ≤ UTCI ≤ 38.0 °C), the AED visit rate (per 100,000) increased by 0.9 (95% CI: 0.5, 1.3) and 1.7 (95% CI: 1.3, 2.1) for females and males aged 19–64 and 4.1 (95% CI: 2.7, 5.4) and 4.1 (95% CI: 2.6, 5.6) for females and males aged ≥ 65, while keeping other variables constant. On a day with very strong heat stress (38.1 °C ≤ UTCI ≤ 46.0 °C), the corresponding rates increased by 0.6 (95% CI: 0.1, 1.2), 2.2 (95% CI: 1.7, 2.7), 4.9 (95% CI: 3.1, 6.7), and 4.7 (95% CI: 2.7, 6.6), respectively. The effect size of heat stress associated with AED visit rates was negligible among those aged ≤ 18. Heat stress showed the greatest effect size for males aged 19–64 among all subgroups. Conclusion Biothermal condition from heat stress was associated with the health of the citizens in a city with a subtropical climate and reflected in the increase of daily AED visit. Public health recommendations have been made accordingly for the prevention of heat-related AED visits.

“…The results demonstrated a strong correlation between the gradient of temperature decrease along the precinct axis (GTD) and the average aspect ratio of the precincts, regardless of whether mitigation strategies were implemented. As a result, the study suggests that implementing urban design interventions that modify the aspect ratio of buildings and streets can effectively mitigate the UHI effect and improve thermal comfort in open spaces [21].…”

Outdoor Thermal Comfort Optimization in a Cold Climate to Mitigate the Level of Urban Heat Island in an Urban Area

et al. 2023

Climatic and micro-climatic phenomena such as summer heat waves and Urban Heat Island (UHI) are increasingly endangering the city’s livability and safety. The importance of urban features on the UHI effect encourages us to consider the configuration of urban elements to improve cities’ sustainability and livability. Most solutions are viable when a city redevelops and new areas are built to focus on aspects such as optimum design and the orientation of building masses and streets, which affect thermal comfort. This research looks beyond outdoor thermal comfort studies using UHI data and geoprocessing techniques in Tallinn, Estonia. This study supposes that designing urban canyons with proper orientation helps to mitigate the UHI effect by maximizing outdoor thermal comfort at the pedestrian level during hot summer days. In addition, optimizing the orientation of buildings makes it possible to create shaded and cooler areas for pedestrians, reducing surface temperature, which may create more comfortable and sustainable urban environments with lower energy demands and reduced heat-related health risks. This research aims to generate valuable insights into how urban environments can be designed and configured to improve sustainability, livability, and outdoor thermal comfort for pedestrians. According to the study results, researchers can identify the most effective interventions to achieve these objectives by leveraging UHI data and geoprocessing techniques and using CFD simulations. This evaluation is beneficial in guiding urban planners and architects in proposing mitigation solutions to enhance thermal comfort in cities and creating suitable conditions for approved thermal comfort levels. Results of the study show that in the location used for the survey, Tallinn, Estonia, the orientation of West-East offers the optimum level of comfort regarding thermal comfort and surface temperature in the urban environment.
