In contemporary cities, and usually without realizing it, the population has been exposed to high sound pressure levels, which besides causing discomfort, can lead to health problems. Considering that a large part of this noise comes from emission from motor vehicles, this research aims to evaluate the sound behavior in sound environments configured by voids in the urban fabric, in order to identify whether open spaces can act as attenuators of sound levels. To obtain the expected results, the methodology used was structured from a review of the state-of-the-art and computer simulations relating the variables that influence the formation of urban space and sound emission and propagation, taking as a case study an urban portion of the municipality of Vitória/ES. In parallel, questionnaires were applied to evaluate the user's perception of their exposure. The measurement results indicated that the sound pressure levels caused by traffic noise are above the limit tolerated limit by the NBR norm 10151:2000 for the daytime period. In turn, the results obtained from the population indicated that there is little perception of noise by the users of the spaces surveyed.

O crescimento urbano acelerado e a ocupacao desordenada do solo podem influenciar negativamente no microclima. Dessa forma a vegetacao e um importante instrumento no auxilio para o provimento de um ambiente termicamente mais agradavel. O objetivo deste trabalho foi avaliar o impacto de alguns diferentes tipos de distribuicao de vegetacao inseridos no meio urbano em relacao ao conforto termico. Foi considerado um trecho urbano, tipologicamente similar na cidade de Vitoria (ES), localizado nos bairros Jardim da Penha e Mata da Praia. Para as medicoes, foram selecionados quatro pontos de amostragem distribuidos retilineamente a partir do Parque Pedra da Cebola. Foram medidas as variaveis climaticas temperatura, umidade e velocidade do vento, realizadas simultaneamente durante tres horas ininterruptas no verao, considerando horarios de maior incidencia solar do dia. Os dados encontrados nas medicoes permitiram constatar a influencia da vegetacao como um forte condicionante para o conforto termico. Verificou-se que a influencia termica da vegetacao concentrada no Parque ocorre apenas no entorno imediato no que diz respeito a temperatura, no entanto, em relacao a umidade, o raio de interferencia e maior. A vegetacao distribuida apresenta resultados mais satisfatorios em relacao a temperatura, quando comparado a sua disposicao concentrada, concluindo-se que embora os parques urbanos exercam influencia no conforto do entorno imediato, a distribuicao da vegetacao na malha urbana tende a trazer melhores resultados.

THE INFLUENCE OF THE VEGETATION IN THE URBAN THERMAL COMFORT FOR CLIMATE CONDITION OF VITORIA (ES) ABSTRACT The accelerated urban growth and the disorderly occupation of the ground may negatively influence the microclimate. Vegetation is an important instrument in the provision of an environment thermally more pleasant. The goal of this paper was to evaluate the impact of some different kinds of distribution of vegetation inserted in the urban environment related to the thermal comfort. It was considered an urban stretch that is typologically similar in the city of Vitoria (ES), located in the neighborhoods Jardim da Penha and Mata da Praia. For the measurements, four sampling points rectilinearly distributed from Pedra da Cebola Park were selected. The climatic variables temperature, humidity and wind speed were measured simultaneously for three hours uninterrupted in the summer, considering the most sunlight hours in the day. The data found in the measurements allows one to realize the influence of the vegetation as a strong constraint for the thermal comfort. It was found that the thermal influence of the vegetation concentrated in the park occurs only in the immediate surroundings regarding the temperature. However, regarding humidity, the interference radius is larger. The distributed vegetation shows more satisfactory results regarding temperature, when compared to its concentrated disposition, allowing one to conclude that, although the urban parks have influence in the comfort of the immediate surroundings, the distribution of vegetation in the urban environment tends to bring better results.

LA INFLUENCIA DE LA VEGETACION EN EL CONFORT TERMICO URBANO PARA LA CONDICION CLIMATICA DE VITORIA (ES) RESUMEN El rapido crecimiento urbano y el uso del suelo sin control pueden influir negativamente en el microclima y la vegetacion es una importante herramienta en la ayuda para la obtencion de un ambiente termicamente mas agradable. El objetivo de este estudio fue evaluar el impacto de los diferentes tipos de distribucion de la vegetacion insertadas en el entorno urbano con respeto al confort termico. Fue considerado un tramo urbano, tipologicamente similar en la ciudad de Vitoria (ES, Brazil), situado en los barrios Jardim da Penha y Mata da Praia. Para las mediciones, fueron seleccionados cuatro puntos de amuestra, distribuidos en linea desde el Parque Pedra da Cebola. Fueron medidas las variables climaticas temperatura, humedad y velocidad del viento, hechas simultaneamente durante tres horas ininterrumpidas en el verano, teniendo en cuenta los horarios de mayor incidencia solar del dia. Los datos obtenidos en las mediciones permitieron comprobar la influencia de la vegetacion como un fuerte elemento para el confort termico. Se comprobo que la influencia termica de la vegetacion concentrada del Parque se produce solo en el entorno inmediato con respecto a la temperatura, sin embargo, con respecto a la humedad, el radio de interferencia es mas grande. La vegetacion, cuando distribuida, resulta mas satisfactoria en relacion a la temperatura, en comparacion a su disposicion concentrada, concluyendo que, aunque los parques urbanos ejercen influencia en la comodidad de sus alrededores inmediatos, la distribucion de la vegetacion en el area urbana tiende a traer mejores resultado.
