In this sense, these points are important for socialhousing, provided that financial limits for this kind of undertaking and the low investmentcapability for building maintenance. Furthermore, the major part of housing shortage isrelated to the lower familiar income. Accordingly, this paper presents a social housing designand its urban plan in Formiga, a tropical climate city in Brazil. This social architecture usessustainable principles, integrating the following features: water and energy conservation,bioclimatic architectonic solution, use of renewable natural resources, besides specification oflow environmental impact materials. Urban and architectonic solutions were suggested inorder to design 89 (eighty nine) dwellings; moreover, on account of the social demand, housesare designed for families with four members. The solution concerns water and energyconservation due to the reutilization of rainwater, low water conservation system, solar waterheating system, along with lighting and thermal comfort performance. Finally, the dwellingunit saves 47% (forty seven percent) of energy consumption and 31% (thirty one percent) ofwater consumption compared to ordinary social housing.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 120
