The universe analyzed in this research is constituted of some of the vertical housing built in Natal from the period of 1969 to 2000. As we could observe there are many different aspects in these apartment buildings external appearance, denoting increasing preoccupations in their formal elaboration in the battlefield for diversity against monotony of the simple prismatic volumetric forms. / Este trabalho foca em temas relacionados com problemas internos ? disciplina da arquitetura, especialmente aqueles que t?m a ver com a est?tica das edifica??es. O universo analisado nesta pesquisa cont?m edif?cios residenciais verticais constru?dos em Natal no per?odo de 1969 a 2000. Como foi poss?vel observar, existem muitos aspectos diferentes na apar?ncia externa destas edifica??es, o que denota preocupa??es crescentes com as suas elabora??es formais no campo de batalha pela diversidade contra a monotonia das formas volum?tricas simples

The study pretends to contribute to the development of design strategies appropriate to the specific local climate and the increasing of energy efficiency level of the envelope. The methodological procedures included the survey in 22 (twenty two) residential buildings, the formulation of representative prototypes based on typological and constructives characters researched and the classification of the level of energy efficiency in the envelopment of these prototypes, using as a tool the prescriptive method of the RTQ-R and the parametric analyzes from assigning different values of the following variables: shape of the pavement type; distribution of housing compartments; orientation of the building; area and shading of openings; thermal transmittance, and solar absorptance of opaque materials of the frontage in order to evaluate the influence of these on the envelopment performance. The main results accomplished with this work includes the qualification of vertical residential buildings in Natal/RN; the verification of the adequacy of these buildings to local climate based from the diagnosis of the thermal energy of the envelopment performance, the identification of variables with more significant influence on the prescriptive methodology of RTQ-R and design solutions more favorable to obtain higher levels energy efficiency by this method. Finally, it was verified, that some of these solutions proved contradictory in relation to the recommendations contained in the theoretical approaches regarding environmental comfort in hot and humid weather, which indicates the need for improvement of the prescriptive method RTQ-R and further research on efficient design solutions / O objetivo desta pesquisa foi investigar o desempenho energ?tico da envolt?ria de edif?cios residenciais verticais no clima quente e ?mido de Natal, capital do estado do Rio Grande do Norte, ? luz do Regulamento T?cnico de Qualidade para o N?vel de Efici?ncia Energ?tica de Edifica??es Residenciais (RTQ-R), lan?ado em 2010. O trabalho procura contribuir para o desenvolvimento de estrat?gias projetuais adequadas ?s especificidades clim?ticas locais e ao aumento do n?vel de efici?ncia energ?tica da envolt?ria. Os procedimentos metodol?gicos inclu?ram o levantamento em 22 (vinte e dois) edif?cios residenciais, a formula??o de prot?tipos representativos com base em caracter?sticas tipol?gicas e construtivas levantadas e a classifica??o do n?vel de efici?ncia energ?tica (etiquetagem) da envolt?ria destes prot?tipos, utilizando como ferramenta o m?todo prescritivo do RTQ-R e an?lises param?tricas a partir da atribui??o de diferentes valores ?s seguintes vari?veis: forma do pavimento tipo; distribui??o dos ambientes na habita??o; orienta??o da edifica??o; ?rea e sombreamento das aberturas; transmit?ncia t?rmica; e, absort?ncia solar dos materiais opacos da fachada, a fim de avaliar a influ?ncia destes no desempenho da envolt?ria. Os principais resultados alcan?ados com a realiza??o deste trabalho compreenderam a qualifica??o dos edif?cios residenciais verticais em Natal/RN; a verifica??o da adequa??o destes edif?cios ? realidade clim?tica local a partir do diagn?stico do desempenho termo-energ?tico da envolt?ria; a identifica??o das vari?veis com influ?ncia mais significativa sobre a metodologia prescritiva do RTQ-R e de solu??es projetuais mais favor?veis ? obten??o de n?veis mais altos de efici?ncia energ?tica segundo este m?todo. Verificou-se, finalmente, que algumas destas solu??es mostraram-se contradit?rias em rela??o ?s recomenda??es consagradas nas abordagens te?ricas relativas ao conforto ambiental no clima quente e ?mido, o que indica a necessidade de aperfei?oamento do m?todo prescritivo do RTQ-R e o aprofundamento em pesquisas sobre solu??es projetuais eficientes
