A Influência dos espaços verdes na temperatura e na percepção do conforto térmico no grande Conjunto Ceará, Fortaleza-Ceará

Abstract

The study addresses the relationship between air temperature, the perception of thermal comfort, and the presence of green spaces in two areas of the Grande Conjunto Ceará, highlighting the importance of vegetation in modulating the urban microclimate. Thermal comfort is defined as the sensation of well-being in relation to ambient temperature, influenced by factors such as air temperature, humidity, wind speed, and solar radiation. The research aimed to analyze how tree coverage affects temperatures, the perception of thermal comfort, and the quality of life of the neighborhood's residents. Thus, the objective of this study was to evaluate the differences in temperature and humidity between an area with green space and another without green space in the Grande Conjunto Ceará, in addition to assessing the residents’ perception of thermal comfort. To achieve this, data were collected through temperature and humidity measurements using a psychrometer, as well as structured interviews with residents. The Effective Temperature Index was used as a parameter to assess the perceived level of thermal comfort. The evaluation of residents’ perception was conducted through questionnaires that addressed their thermal sensations at different times of the day and under varying environmental conditions. The results showed that areas with more trees offer greater thermal comfort, while areas lacking vegetation contributed to thermal discomfort and may lead to health problems and increased air conditioning costs. The study concluded that tree coverage is crucial for the creation of more sustainable cities, suggesting the need for public policies that prioritize the implementation and maintenance of green spaces. The data collected and analyzed serve as a basis for reflecting on the development of urban planning strategies aimed at improving thermal comfort and quality of life in the Grande Conjunto Ceará.
