Summary: The urban climate is an important factor for the quality of the urban environment.
Understanding its dynamics and interrelationship with the built environment makes it
possible to establish strategies for actions that culminate in improving the quality of
life of its users, more efficient spatial arrangements and the reduction of risks related
to human health and safety. The challenges imposed by climate change and
population increase in urban centers reiterate the urgency for actions to ensure good
environmental conditions. Furthermore, there is an urgent need for studies aimed at
reducing the lack of integration between urban climate knowledge and planning
practices. This research aimed to propose a methodology for urban climate mapping
on the microclimate scale, qualified to delimit urban guidelines capable of
contributing to thermal improvement of urban centers. The methodology was
presented from the application of an analytical model aimed at the study of the urban
thermal field, based on the structure of the Urban Climate Map (UCMap). The
method was associated with modeling and climate measurements carried out in a
seasonal winter situation. Spatial distribution maps of the air temperature and
humidity variables were correlated to the different thermal fields and heating
potentials delimited by the model, in order to assess its accuracy. The study in
question was carried out in an urban area located in the Jardim Camburi
neighborhood, located in the city of Vitória (Espírito Santo). As a result, it was verified
the positive effect of the parameters of urban capacity, shading (caused by
afforestation and buildings) and green areas in mitigating the adverse effects of the
thermal load. On the other hand, it was observed that the areas with the greatest
heating potential pertain to places with high emissivity and built-up volume
associated with greater exposure to direct sunlight. Regarding the microclimate of the
evaluated area, thermal differences were observed between the monitored points of
up to 2.6 °C in the morning, 3.8 °C in the afternoon and 1.7 °C in the night shift.
Given these results, guidelines were developed as a subsidy for local urban planning.
