Heat Island Effect in Urban Areas
Heat Island Effect in Urban Areas

Summary/Abstract: In densely built urban environments, microclimate characteristics are critically important in terms of comfort and health conditions for residents (thermal comfort/thermal stress), but also in relation to environmental performance and, implicitly, the energy performance of urban areas. Given the context of climate change, the increasing frequency of heat waves, awareness of the need to ensure conditions for resilience and analysis of variations and developments in the urban microclimate have grown. It is important to note that the evolution of the urban microclimate not only influences the feeling of thermal discomfort experienced by the population in public spaces due to rising outdoor temperatures, but also amplifies the thermal stress resulting from the overheating ofindoor spaces, including in residential units, resulting in an increase in the energy required for air conditioning. Thus, the simulation of the energy behavior of buildings inurban areas is conditioned by a prior assessment of the UHI intensity in the analyzed area."Together with climate change, this phenomenon may be crucial to how we view urban areas as living environments."
