Special Issue Information

Dear Colleagues,

Local climate change, including but not limited to the Urban Heat Island effect, is driven by the increasing expansion of our cities and enhanced by global climate change. The ensuing outcome is one of the main environmental challenges of today with major impacts on energy and human health. As the outdoor ambient temperature is increased during the cooling season, total and peak cooling energy and electricity demands rise consequently. Additionally, urban overheating impacts human well-being and health, ranging from increased thermal stress to peaks in morbidity and mortality, specifically during heatwaves. Therefore, it is paramount that mitigation and adaptation strategies for urban heating and overheating are proposed and assessed in detail.

To respond to this urgency, we invite researchers to contribute original research and review articles dealing with all aspects of urban heating and its impact on human life in urban areas. These contributions include recent experimental and modeling studies, implementing techniques and developments tailored to the assessment of urban heating, as well as mitigation and adaptation scenarios proposed and assessed in various urban climates. We are also interested in reviews with possible future lines of investigation. Topics of interest include, but are not limited to:

  • To investigate the impact of urban overheating on building energy needs, electricity demand, health, economy, and hygrothermal comfort.
  • To propose comprehensive methodologies and metrics for quantifying the local and global impact of urban overheating.
  • To present the cooling potential of innovative mitigation and adaptation technologies (from both urban and building design perspectives). In particular, we are interested in original contributions on the development and testing of methods to measure and model the performance of consolidated and advanced technologies, with the identification of the elements of uncertainty, evaluating their reliability and performance in the context of application.
  • To evaluate the impact and role of advanced mitigation and adaptation policies on human health, energy, peak electricity demand, environment, economy, and comfort.
  • To present innovative application of mitigation and adaptation solution in large-scale projects both at the theoretical and experimental level.

We look forward to receiving your contributions.

(1) Background: Although the health effects of future climate change have been examined in previous studies, few have considered additive impacts of population expansion, ageing, and adaptation. We aimed to quantify the future heat-related years of life lost (YLLs) under different Representative Concentration Pathways (RCP) scenarios and global-scale General Circulation Models (GCMs), and further to examine relative contributions of population expansion, ageing, and adaptation on these projections. (2) Methods: We used downscaled and bias-corrected projections of daily temperature from 27 GCMs under RCP2.6, 4.5, and 8.5 scenarios to quantify the potential annual heat-related YLLs in Guangzhou, China in the 2030s, 2060s, and 2090s, compared to those in the 1980s as a baseline. We also explored the modification effects of a range of population expansion, ageing, and adaptation scenarios on the heat-related YLLs. (3) Results: Global warming, particularly under the RCP8.5 scenario, would lead to a substantial increase in the heat-related YLLs in the 2030s, 2060s, and 2090s for the majority of the GCMs. For the total population, the annual heat-related YLLs under the RCP8.5 in the 2030s, 2060s, and 2090s were 2.2, 7.0, and 11.4 thousand, respectively. The heat effects would be significantly exacerbated by rapid population expansion and ageing. However, substantial heat-related YLLs could be counteracted by the increased adaptation (75% for the total population and 20% for the elderly). (4) Conclusions: The rapid population expansion and ageing coinciding with climate change may present an important health challenge in China, which, however, could be partially counteracted by the increased adaptation of individuals.

Growing and densifying cities set a challenge for preserving and enhancing green spaces to cool urban spaces. Green roofs, involving the planting of vegetation on rooftops, are regarded as an alternative approach to enhancing urban greenery and urban cooling. For better cooling performances, it is essential to reasonably configure green roofs, especially in real and complex neighborhoods. Therefore, the aim of this paper is to investigate the impact of morphological characteristics of green roofs on pedestrian cooling in real and complex neighborhoods. In specific, based on an ENVI-met model, we studied the effect of greening layout, coverage ratio, vegetation height, and building height on pedestrian air temperature reduction in the tropical city of Hangzhou, China. Results indicate green roofs could generate moderate effects on pedestrian air temperature reduction (around 0.10–0.30 °C), while achieving a cooling performance of 0.82 °C. Green roofs in upwind zones were able to generate the most favorable cooling performance, while green roofs in downwind zones made slight differences to pedestrian thermal environments. Green roofs with a low coverage ratio were not useful for lowering pedestrian temperature, and a greening coverage ratio of 25–75% in upwind zones was cost-effective in real neighborhoods. Locations that were horizontally close to green roofs enjoyed better cooling performances. Increasing vegetation height could strengthen cooling effects of green roofs, while an increase in building height weakened the cooling performance. Nevertheless, higher building height could enhance pedestrian cooling performances because of building shading effects. In addition, because of wind effects and building shading, building height limits for the cooling performance of green roofs could be higher than 60 m. Full article

Extreme temperatures impose thermal stress on human health, resulting in increased hospitalizations and mortality rate. We investigated the circulatory and respiratory causes of death for the years 2007 to 2014 inclusive for the urban and rural areas of Nicosia, Cyprus under urban heatwave and non-heatwave conditions. Heatwaves were defined as four or more consecutive days with mean urban daily temperature over the 90th percentile threshold temperature of the eight investigated years. Lag period of adverse health effects was found to be up to three days following the occurrence of high temperatures. The relative risk (RR) for mortality rate under heatwave and non-heatwave conditions was found taking in consideration the lag period. The results showed the increase of mortality risk particularly for men of ages 65–69 (RR = 2.38) and women of ages 65–74 (around RR = 2.54) in the urban area, showing that women were more vulnerable to heat extremities. High temperatures were also associated with high ozone concentrations, but they did not impose an excess risk factor, as they did not reach extreme values. This analysis highlights the importance of preparing for potential heat related health impacts even in Cyprus, which is an island with frequent heatwaves. Full article
