Caracterização geométrica de projetos residenciais: um estudo de caso na cidade de Crateús-CE

Abstract

Despite of the architectural design represent a small portion of construction cost, it is at this stage that major decisions are made regarding the building spaces, facilities, finishing standards and more. These decisions influence substantively the total cost and built environment quality and deserves more attention, because of the dissatisfaction of end users with the built environment is intrinsically related to architectural design. Thus, this works aimed to perform the geometric characterization of residential buildings from city of Crateús, state of Ceará, northeast of Brazil. Based on a wide literature review, eight geometrical indicators regarding cost efficiency and quality of built environment were selected. Then, these indicators were applied to 60 housing projects from city of Crateús and provided an overview of the main features of architectural design of the residential buildings, that can be used for assessing the quality of design. Besides that, the indicators can be used to visualizes the project cost in advance, conducting a best decision making that optimizes the quality and cost of built environment. The geometrical indicators were also compared with literature to check its similarities with housing projects from other Brazilian regions. It was perceived similarities regarding some indicators like compacity and density of wall. Nevertheless, other indicators showed great divergence from the literature. It is concluded that the use of geometric indicators is a valid strategy to improve project quality and costs. It was evidenced that the architectural designs of residences at Crateús can be considered as satisfactory. Future studies were suggested.
