This Master s thesis deals with the application of bioclimatism concepts to urban designs, with focus on thermal environments. Inspired by vernacular architecture techniques, bioclimatism comprises, in a systematic way, studies of climatology, biology, technology and architecture. It seeks harmony between already built and natural spaces for human comfort. As a multidisciplinary area of knowledge, it brings the progressive systematization and evolution of its original goals, i.e., building not only with focus on comfort, but also on using the energy potential of a given location. While constituting its habitat, the perception of climatic phenomena was fundamental to humanity in order to find adequate responses in search of protection, comfort and thermal balance, which are essential items to humanity s well-being and survival. These responses were materialized in the architectural and urban expressions of human settlements, characteristic of various regions of the world and eras of civilization. This evolution took place according to the degree of knowledge, technological development and culture of the regions. A healthy environment, with efficient use of natural resources, is one of the main goals of a sustainable city. The bioclimatic urban project is inserted in this concept and can contribute to improve the well-being and enhance the sustainability of contemporary urban spaces. Studies show that the urban climate is directly related to the form of a city. Performing urban designs without taking environmental impacts into consideration often has negative consequences for the environment and, consequently, for the health and comfort of the inhabitants.
