Along with natural scarcity in some regions, this is one of the factors that limit the availability of drinking water. As a result, the conservation of drinking water is becoming one of the major concerns in sustainable architectural projects. Within this context, this dissertation proposes to develop the design of an educational building focusing on water consumption rationalization. The proposed project is located in UFRN Campus at Currais Novos, an area of warm and dry climate and low rainfall. The proposal seeks to integrate ways to reduce water consumption o to architecture, in order to exploit the advantages and savings. After quantifying the benefits achieved, it was concluded that it is possible to reduce significantly the drinking water consumption in educational buildings in universities using three principles: reduction the water consumption at the point of use, replacement of the water source and internal recycling. Calculations and simulations indicated that the proposed building may have water consumption up to 56% lower than if it would be provided by conventional facilities. Rationalization of water consumption brings direct and indirect benefits, with influences on the environmental, social and economic fields / O crescimento urbano sem a infraestrutura pr?via tem provocado diversos impactos ambientais, como o comprometimento da qualidade das reservas h?dricas nas cidades. Juntamente com a escassez natural em certas regi?es, este ? um dos fatores que limitam a disponibilidade de ?gua para consumo. Em fun??o disso, a conserva??o da ?gua pot?vel vem se tornando uma das principais preocupa??es nos projetos arquitet?nicos sustent?veis. Dentro deste contexto, este trabalho se prop?e a desenvolver um projeto de arquitetura para um edif?cio de ensino superior com foco na racionaliza??o do consumo de ?gua. O projeto proposto situa-se no campus da UFRN no munic?pio de Currais Novos, ?rea de clima quente e seco e de baixa pluviometria. A proposta busca integrar medidas de redu??o do consumo de ?gua ? arquitetura, com a finalidade de explorar quais as vantagens trazidas e a economia alcan?ada. Ap?s a quantifica??o de benef?cios das medidas adotadas, constatouse que ? poss?vel reduzir significantemente o consumo de ?gua pot?vel nos edif?cios educacionais em universidades utilizando-se tr?s princ?pios: redu??o do consumo de ?gua no ponto de utiliza??o, substitui??o da fonte de ?gua e reciclagem interna. Os c?lculos e simula??es realizadas indicaram que a edifica??o proposta pode ter um consumo at? 56% menor do que se fosse provida por instala??es hidrossanit?rias convencionais. A racionaliza??o do consumo de ?gua traz benef?cios diretos e indiretos, com desdobramentos no campo ambiental, social e econ?mico
