The objective of this study was to analyze the impact of an urbandevelopment on the variables of the urban climate. The climatic variables involved were air temperature and relative humidity. They were related with the urban fabric variables of construction mass and sky view factor, in order to study the effects of the urban geometry and thermal inertia on the local climate change. An urban area in development at the border between the cities of Belo Horizonte and Nova Lima, State of Minas Gerais, Brazil, was selected as a study area. This area was divided into two transect path with a total of twenty-four measure points. Data of air temperature and humidity were collected each 3 hours, starting at 3 p.m. during 24h. These data were used to build 2 empirical equationsrelating climatic variables and urban fabric variables. Using the techniques of scenarios, the local urban developed was occupation projected to 10 years ahead (2016) the new values of the urban fabricvariables were then calculated. Doing so, new estimates of the air temperature and humidity for this future scenario could be made through the empirical equations. These new data were plotted on the 2016 map of land use and occupation allowing the assessment of tendencies of changing climatic variables related to urban development. The increase of construction density and the arrangement geometry among the buildings were observed as the main aspects to cause changes in thelocal horizontal spatial distribution of the air temperature and humidity.This methodology is thought to be useful in urban planning and design as long as a responsible urban climate design is concerned. The method could be applied to evaluate the impact of the urban legislation on environmental aspects of the area, though the comparison among different design solutions.
