O correto dimensionamento das redes hidrossanitárias prediais não é somente
indispensável para o conforto e qualidade de vida nas edificações, mas também para
garantir saúde do usuário e da estrutura do edifício. Não existe, no entanto, consenso
sobre os métodos de dimensionamento, que diferem em cada país ou região.
Esta dissertação pretende comparar e discutir os métodos de dimensionamento
para redes prediais de abastecimento de água e drenagem de águas residuais e pluviais
propostos pelo Regulamento Português, pelas Normas Europeias e pelas Normas
Brasileiras, com objetivo de avaliar incongruências e especificidades de cada uma.
Ainda que Portugal faça parte do Comitê Europeu de Normalização, as Normas
Europeias ainda não são muito aplicadas no país, devido à existência do Regulamento
Português em vigor, o qual apresenta grandes diferenças. Já em relação ao Brasil, é
interessante avaliar e comparar as normas, se considerado o elevado intercâmbio de
profissionais entre os países.
Em primeiro momento, o trabalho propõe uma resenha histórica sobre a história
das instalações prediais e do avanço das regulamentações que tratam delas.
Posteriormente é realizada uma revisão criteriosa das normativas correntes em Portugal,
na Europa e no Brasil.
Os métodos das normas são então aplicados no dimensionamento dos sistemas
hidrossanitários de uma residência unifamiliar de três pavimentos. Com os resultados
obtidos são realizadas comparações entre os métodos, avaliando a praticidade de
aplicação e os níveis de conforto considerados.
Percebe-se que as Normas Europeias apresentam tendência de simplificação nos
métodos de dimensionamento e também são menos exigentes em questão de dimensões
das tubagens. O Regulamento Português é mais conservador nos caudais considerados e
dimensões mínimas. Já as Normas Brasileiras são mais criteriosas para dimensionamento
das redes prediais de abastecimento de água, mas em geral resultam em diâmetros
nominais parecidos e intermediários entre os resultados das demais normas.
The correct dimensioning of the hydro-sanitary installations inside buildings is not only indispensable for comfort and life quality, but also to ensure health to both the user and the building’s structure. However, there is no consensus about the pipe sizing methods, that differs according to the country or region. This master Thesis intends to compare and discuss the pipe sizing methods for building systems of water supply, and drainage of wastewater and rainwater proposed by the Portuguese Regulation, the European Standards and Brazilian Standards, with purpose of evaluating mismatches and specifications of each one. Even though Portugal is part of the European Committee for Standardization, the European Standards are not very applied in the country yet, because of the existence of the Portuguese Regulation in force, which presents many differences. Regarding Brazil, it is interesting to compare the standards if considered the high exchange of professionals between the countries. In a first moment, this work proposes a historic review on the history of the building water systems and the advance of the regulations about them. Afterwards it is done an insightful review on the current standards in Portugal, Europe, and Brazil. The methods of the standards are applied in the pipe sizing of the systems of a three-pavement single family residence. With the results of the calculations are performed comparisons, evaluating the convenience of application and the levels of comfort considered. It is perceived that the European Standards tend to simplify the sizing methods and are also less demanding about the pipe sizes. The Portuguese Regulation is more conservative about the flow rates considered and the minimal pipe sizes. The Brazilian Standards are more specific in the water supply sizing but tend to result in similar and intermediate nominal diameters between the other regulations.
