This study aims to analyze the thermal comfort in urban areas for
different land uses. The ENVI- met microclimatic model has been used for
urban boundary layer simulation, providing the following thermal
comfort indexes: PMV (Predicted Mean Vote) and PPD (Predicted Percentage
of Dissatisfaction). The chosen area covers the central area in the
city of Ourinhos, located in southeastern Brazilian city, with
subtropical climate. Four simulations were accomplished: an area with
real buildings and vegetation on site, a “grassy” area where buildings
have been replaced by grass in the central area, another grassy area,
known as “grass/tree”, with additional trees in, and a final area called
“Park” also grassy, where trees were added all over the area. The
structures which showed thermal comfort within the ISO 7730 standards
were the grassy area with no trees at 9 a.m., and a paved area, as well
as the park area at 3 p.m. Other situations have presented values of PMV
and PPD off the limits required by the rules; they were very close to
those values. The only point that presented a far cry from the comfort
required was the spot in the asphalt at 9 a.m. The other situations
showed PMV and PPD values not far from the limits of comfort. Only the
point on the asphalt showed values far from the limit of comfort at 9
a.m.
