Master Plan. It develops a diagnosis of the evolution and growth of the urban space surveyed by analyzing its initial plan and the basic urban conception behind it, as well as the morphology and typologies utilized. The study makes a qualitative analysis of the local microclimate by using Katzschner (1997) methodology, with land-use and topography maps, building heights, vegetation and soil covering. It also makes use of the methodology proposed by Oliveira (1993), which examines, from the bioclimatic standpoint, the human environment as related to the urban form (site and built mass). It identifies zones whose climatic characteristics are representative of the local microclimate and classifies them into areas to be strictly preserved, areas to be protected and areas to be improved. By means of the methodology for spatial and environmental assessment developed by Bustos Romero (2001), the survey selects characteristic points of each area in order to register the environmental data relative to the two basic seasons found in the region where the campus is located, that is, the dry and the rainy season, so that it can evaluate changes in the environment which might have been caused by urban density growth, by arborization or by the influence of the urban form. It then proceeds to a quantitative and statistical survey of the collected data with the purpose of evaluating the degree of influence of the identified features over the environmental variables along the different scales of approach. The study shows the existence of different microclimates and emphasizes the relevance of the bioclimatic analysis of the built environment as a tool for the decision-making process along the development of the Master Plan for UFRN Central Campus / Esta pesquisa trata da investiga??o do microclima e dos atributos da morfologia do Campus Central da UFRN, em Natal-RN, utilizando ferramentas de an?lise bioclim?tica, para subsidiar a implementa??o do seu Plano Diretor. Realiza um diagn?stico da evolu??o e crescimento do espa?o urbano em estudo, com aprecia??o do plano inicial, partido adotado, morfologia e tipologias utilizadas. Realiza uma an?lise qualitativa do microclima local utilizando a metodologia de Katzschner (1997), com a elabora??o de mapas de uso do solo, topografia, altura dos edif?cios, vegeta??o e recobrimento do solo; e da metodologia proposta por Oliveira (1993), onde analisa bioclimaticamente o meio antr?pico quanto aos atributos da forma urbana (s?tio e massa edificada). Identifica zonas com caracter?sticas clim?ticas representativas do microclima local e as classifica em ?reas a serem preservadas, ?reas a serem protegidas e ?reas a serem melhoradas. Seleciona pontos representativos dessas ?reas, onde aplica a metodologia de Bustos Romero (2001) para avalia??o espacial e ambiental. Nestes pontos, registra os dados ambientais nos dois per?odos caracter?sticos da regi?o em estudo (chuvoso e seco), de modo a identificar altera??es neste ambiente, proporcionadas ou n?o pelo adensamento urbano, pela arboriza??o ou pela influ?ncia da forma urbana. Realiza an?lise quantitativa e estat?stica dos dados coletados, para constatar a representativa influ?ncia dos atributos identificados sobre as vari?veis ambientais, nas diversas escalas de abordagem. Constata a exist?ncia de microclimas diferenciados e enfatiza a relev?ncia da an?lise bioclim?tica do ambiente constru?do, visando orientar decis?es para o Plano Diretor do Campus Central da UFRN

The research was developed in the district of Petr?polis in Natal/ RN whose occupation has been almost consolidated. Among other reasons, this district was selected because it was planned considering the environmental aspects of comfort. The methodologies used are based on KATZSCHNER (1997) and OLIVEIRA (1988) studies, which suggest the drawing and analysis of maps of the area under study, including topography, height of the buildings, land use, green areas, and types of soil pavement, as well as measurement of the environmental variables: air temperature, relative humidity, direction and wind speed for a comparative study. As part of this, study local users of the district were interviewed about their thermal sensations in open spaces. For the statistical analysis, data was collected at 10 distinct points characterized by BUSTOS ROMERO (2002), being 8 within the district and 2 at different places (outside the district), at climatologic stations, in 3 periods (August/2000, January/2002 and June/2002), for 4 consecutive days for each measurement (from Sunday to Wednesday) at the time of lower and higher temperatures in the city, 6:00 am and 1:00 pm, respectively. At the same time interviews were carried out with users of the open spaces in the area, totaling 171 valid formularies. The urban form showed a rather leveled topography, great diversity of land use and height of the buildings, with the existence of an area mostly occupied with high buildings, very little green area and soil practically impermeable. The statistical analysis showed high temperature and humidity levels. The wind direction is predominantly Southeast with extremely variable speeds. When the data from this district is compared with the data from other areas in the city and its outskirt, it was observed that this district is hotter and less ventilated than the others; besides, most users said that they felt uncomfortable in the local environmental conditions. The results of the analysis generated a zoning for the district with recommendations for soil occupation. The profile of the user was defined regarding the thermal comfort, as well as some discussion about the comfort parameters, including the proposal of limiting areas of temperature and humidity for the thermal comfort in the open spaces / Este estudo pretendeu investigar a maneira como a forma urbana vem influenciando as altera??es no clima da cidade e correlacion?-la com a sensa??o t?rmica do usu?rio do ambiente externo. A pesquisa ambientou-se no bairro de Petr?polis em Natal/ RN, que tem sua ocupa??o em parte consolidada e foi escolhido, dentre outras raz?es, por ter sido planejado levando-se em considera??o aspectos ambientais de conforto. As metodologias adotadas baseiam-se nos estudos de KATZSCHNER (1997) e OLIVEIRA (1988) que sugerem a elabora??o e an?lise de mapas da ?rea de estudo como topografia, altura das edifica??es, uso do solo, ?reas verdes e tipo de recobrimento do solo, aliados ? medi??o de vari?veis ambientais: temperatura do ar e umidade relativa, a velocidade e a dire??o dos ventos, para compara??o; al?m de entrevistas sobre a sensa??o t?rmica dos usu?rios do ambiente externo. Para a an?lise estat?stica foram levantados dados em 10 pontos distintos, caracterizados segundo m?todo proposto por BUSTOS ROMERO (2002), sendo 08 dentro do bairro e 02 fora dele, em esta??es meteorol?gicas, durante 03 per?odos (agosto/ 2000, janeiro/ 2002 e junho/ 2002), por 04 dias seguidos em cada per?odo (de domingo a quarta-feira), nos hor?rios de menor e maior temperatura para a cidade, 06h e 13h respectivamente. Simultaneamente, foram realizadas entrevistas com os usu?rios do ambiente externo do bairro, totalizando 171 formul?rios v?lidos. A forma urbana encontrada apresentou topografia pouco acidentada, grande diversidade de uso do solo e de altura das edifica??es com exist?ncia de n?cleo verticalizado, muito pouca ?rea verde e terreno praticamente imperme?vel. A an?lise estat?stica evidenciou altas temperaturas e umidades, e dire??o predominante dos ventos Sudeste, com velocidade bastante vari?vel. Quando comparados aos dados de outras ?reas da cidade e arredores, verifica-se que o bairro ? mais quente e menos ventilado; al?m disso, a maioria dos usu?rios sentiu-se desconfort?vel com as condi??es ambientais locais. Os resultados das an?lises possibilitaram um zoneamento para o bairro aliado a diretrizes para ocupa??o do solo; foi tamb?m tra?ado o perfil do usu?rio em conforto t?rmico e, levantadas algumas discuss?es acerca de par?metros de conforto, inclusive com a proposi??o de faixas limites de temperatura e umidade relativa do ar para o conforto t?rmico no ambiente externo

It is presented as object of study the correlation between the neighborhood Renascen?a II s microclimate in S?o Luis /MA-Brazil, hot-humid climate city, and its urban morphological changes. As well as the thermal comfort s satisfaction level of its outdoor users. The research has as general goal to diagnosis the way these transformations caused by the urbanization influence the Renascen?a II s microclimate, identifying critical spots of the studied area, in order to contribute with land use recommendations based on bioclimatic architecture concepts and supply bases to urban design decisions adequate to the S?o Luis climate. It is presented as theoretical bases the urban climate, its concepts and elements. After that, the thermal comfort conditioners and its prediction models of thermal comfort sensation in outdoor are presented. The predictive models are presented along with bioclimatic assessment methods. Finally the use of bioclimatic assessment as an effective tool to identify places that need changes or preservation in order to seek environment quality. The applied methodology was based on the studies of Katzschner (1997), complemented by Oliveira s (1988) and Bustos Romero s (2001) studies that suggest an analysis and evaluation of maps of topography, buildings floors, land use, green areas and land covering, in order to overlap their characteristics and identify climate variable s measurements points; then a quantitative analysis of the climate variables (air temperature and humidity, wind speed and direction) of the chosen points takes place. It was perceived that Renaissance II has no permanence areas as squares or parks, its outdoor has little vegetation and presets high land impermeability and built density levels. The majority of the people interviewed said that was comfortable in a range of air temperature between 27,28?C and 30,71?C. The elaboration of a neighborhood master plan is important, which defines strategies for improvement of the life quality of its inhabitants / O presente trabalho parte das preocupa??es com as condi??es de conforto t?rmico dos espa?os externos em cidades de clima quente-?mido, entendendo que a qualidade de vida neste ambiente ? fruto do tipo de objeto urbano constru?do para a viv?ncia humana em um meio ambiente com clima e caracter?sticas morfol?gicas espec?ficas. Apresenta-se como objeto de estudo a correla??o entre o microclima do Bairro do Renascen?a II em S?o Luis/MA, cidade de clima quente ?mido frente ?s mudan?as nas caracter?sticas morfol?gicas urbana e o ?ndice de satisfa??o de conforto t?rmico dos usu?rios dos espa?os externos do bairro em quest?o. Tem como objetivo geral diagnosticar a maneira como as transforma??es ocasionadas pela urbaniza??o influenciam o microclima do Renascen?a II, identificando ?reas cr?ticas da ?rea estudada, a fim de contribuir com recomenda??es de uso e ocupa??o do solo baseadas em conceitos de arquitetura bioclim?tica e fornecer subs?dios a futuras decis?es projetuais urbanas adequadas ao clima quente e ?mido de S?o Luis-MA. Apresenta-se como fundamenta??o te?rica o clima urbano, seus conceitos, elementos formadores e condicionantes. Em seguida, os condicionantes do conforto t?rmico e seus modelos de predi??o de sensa??o de conforto t?rmico em espa?os externos. Foram levantados os modelos preditivos de conforto e estresse t?rmico como ferramenta junto ? an?lise bioclim?tica. E finalmente a utiliza??o da an?lise bioclim?tica no diagn?stico do conforto t?rmico de ?reas urbanas, com sua efic?cia na identifica??o de locais que necessitam de mudan?as quanto ao conforto ambiental, merecendo aten??o ou at? prote??o; e suas estrat?gias na busca por cidades mais adequadas ao seu meio natural, resultando no urbanismo bioclim?tico. A metodologia aplicada baseou-se nos estudos de Katzschner (1997), complementados por Oliveira (1988) e Bustos Romero (2001) que sugerem uma an?lise e avalia??o de mapas de topografia, altura das edifica??es, uso do solo, ?reas verdes e tipo de cobertura do solo, para superposi??o e identifica??o de pontos para medi??o; a partir da? uma an?lise quantitativa com aferi??o das vari?veis ambientais (temperatura e umidade do ar, a velocidade e a dire??o dos ventos) nos pontos escolhidos. Percebeu-se que o bairro do Renascen?a II n?o possui ?reas de perman?ncia como pra?as e parques, as suas ?reas externas possuem pouca arboriza??o e apresenta alto ?ndice de impermeabilidade e alta densidade construtiva. A maioria dos entrevistados disse estar confort?vel em uma faixa de temperatura do ar entre 27,28? e 30,71?C. ? importante a elabora??o de um plano diretor para o bairro, definindo de estrat?gias para melhoria da qualidade de vida de seus habitantes
