Análise dos aspectos da morfologia urbana e sua relação com a percepção dos teletrabalhadores da qualidade de ambientes de trabalho remoto residenciais localizados em ilhas de calor na cidade de João Реssоа-PB

Abstract

The progressive process of urbanization has led to significant changes in urban spatial forms, contributing substantially to the reproduction of urban models with low environmental quality. With the intensification of telework trends in the post-COVID-19 pandemic context, homes have become extensions of corporate environments This shift has created an opportunity to reflect on indoor comfort and the potential influence of urban morphology. Accordingly, this study aimed to investigate the similarities between aspects of urban morphology and perceived environmental comfort among professionals working remotely in residential environments located in urban heat islands in João Pessoa, Brazil. The methodology consisted of the analysis and morphological mapping of the urban fabric surrounding the remote work environments, through the study of morphological indicators such as built density, occupancy rate, roughness, verticality, average prospect, vegetation cover density, and sky view factor (SVF), with the support of QGIS 3.34 and RayMan 3.1 software. The study of professionals' perception of environmental quality was conducted through the application of questionnaires, which assessed the following variables: thermal, lighting, and acoustic comfort. To analyse the similarities between perceived environmental quality and the influence of the urban surroundings, binary logistic regression models were employed. The results indicated that the surroundings of the 35 remote workstations exhibit highly diverse urban forms, with varying degrees of urban density, vegetation cover, and building characteristics. Regarding the perception of indoor environmental quality, specifically thermal comfort, the majority of teleworkers reported feeling slightly uncomfortable (46%) or comfortable (40%), with most indicating a thermal sensation of being slightly warm (40%). Concerning lighting comfort, 74% of the occupants considered the lighting to be moderate, and 66% reported being moderately satisfied. Associations were identified between thermal comfort perception and roughness and SVF; between acoustic comfort perception and SVF; and between lighting comfort perception and vegetation density.
