This thesis deals with the comparison of rainwater and its subsequent use. Especially, it compares the rainwater from the classical and green roofs. The thesis is divided into two parts. The first part deals with roofs in general, it focuses mostly on green roofs and green roofs in Norway. It also deals with precipitation and the use of rainwater. In the second part there is a brief introduction of organization called „Open Garden“. Susequently, this art is focused on the analysis of samples and their subsequent coparison in the framework of classic and green roofs. The second part is also focused on the comparison of water quality during the time.

[pt] A pesquisa analisou a viabilidade econômica para implantação de um sistema de aproveitamento de água de chuva em condomínio do Programa Minha Casa Minha Vida (PMCMV), já construído, na cidade do Rio de Janeiro. A água é um recurso natural de valor econômico, estratégico e social, além de essencial para manter a existência humana e dos ecossistemas no planeta. A falta de água, que no Brasil se manifesta de modo mais grave desde 2014, envolvendo problemas de seca e de gestão dos recursos naturais, não afetaria somente residências, mas também agricultura e indústrias, as últimas localizadas principalmente na região Sudeste. No entanto, em face dessas perspectivas, a cidade do Rio de Janeiro optou por isentar os empreendimentos imobiliários vinculados ao PMCMV da construção de sistemas de aproveitamento e reuso da água de chuva, apesar de decreto municipal já aprovado desde 2004. O aproveitamento poderia diminuir a necessidade da utilização de água tratada em determinadas atividades, além de contribuir com a diminuição dos custos do condomínio e o impacto de enchentes em meio urbano. Nesta dissertação foi feita a análise econômica da implantação de um sistema de aproveitamento de água de chuva, considerando três alternativas de reservatório, que representa o maior custo da implantação do sistema, por meio de indicadores como o valor presente (VP), o valor presente líquido (VPL), a taxa interna de retorno (TIR), o índice de lucratividade (IL) e o payback simples. Como resultado, foi constatada a viabilidade econômica do sistema de aproveitamento de água de chuva, com redução de 3,6 por cento no consumo de água tratada do condomínio e um valor presente líquido (VLP) de 14.258,04 reais. / [en] Water is the most important natural resource for society, due to its economical, strategical and social value, being vital for life on the planet. As a renewable good, it must be managed in a conscious way, once it may become scarce. With population growth and the development of economies, there is a tendency for the enhancement of its demand. In a survey carried out by the United Nations - UN (2018), this increase varies around 20 percent to 30 percent, that is, 4600km cubic/ year until 2050. In Brazil, the lack of water peaked in 2014, but it is recurrent in the country s large urban centers. As well as in the Northeast region due to climatic and meteorological aspects. Therefore, the rainwater utilization arises as a response for the problems of the impacts caused by the lack of water in large urban centers. This form of treatment would minimize the use of water sources, the cost of water treatment, the impacts of floods and the costs of the population with water bills. With the use of rainwater being implemented in condominiums, the perspective is to reduce the demand for treated water. As a result, lower water bill payments and, thus, reducing the impact of the population s cost of living. A and not less important, to reduce the pressure on the demand of the companies and to smooth the withdrawal of water resources from the environment. As a goal, the research analyzed the system to be implemented, its cost and economic viability in buildings already constructed. In urban centers, there is a demographic density already established, which demands a large amount of water, and also consolidated buildings that aggravate the impact of water scarcity. To achieve this objective, this research simulated the implementation of a rainwater recovery system, considering three reservoir alternatives. Then, a case study was carried out in the Park Riviera da Costa condominium, in the city of Rio de Janeiro, in the neighborhood of Campo Grande, using indicators such as Present Value (VP), Net Present Value (NPV), the Internal Rate of Return (IRR), Profitability Index (IPV) and simple payback.

The diploma thesis is focused on rainwater reuse in the sports and cultural center and elaboration of project sanitary equipment installation. The theoretical part of the thesis is focused on performance issues rainwater reuse in the buildings. In another part of thesis are drawn calculations with three variants of the design volume storage reservoir for rain water. The drawings are part of the project.

This diploma thesis is devoted to a rainwater management in commercial and administrative buildings. The goal of this work is to describe rainwater management system with a focus on its later usage. The work is divided into theoretical and practical parts. The first part examines the binding conditions, as well as the individual technologies and devices that must be included in the implementation of a rainwater management system. The practical part of the work is an analysis of the possibility of using rainwater for the needs of the fire brigade in Havlíčkův Brod. The result of this work is a calculation of the approximate payback period of the proposed system.

The goal of this diploma thesis is the design of the sanitary installations and gas main in the pension for pensioners. The building has three floors above ground and one underground floor. The building will be covered with a hiped roof. On the first floor there is the technical background of the building, Reception and kitchen with dining room. The basement is located just below the kitchen and serves as a cloakroom for kitchen staff. The building will be designed to use as much non-potable water as possible in the form of rainwater, which will be collected from the roofs. The theoretical part deals with the use of non-potable water as operating water in buildings. The calculation and project part deals with the gravity sewer system, plumbing and gas main in the building.

The Master's thesis solves questions about sanitation installations in a multiple dwelling house with underground garages in Brno. The theoretical part of this work focuses on the analysis of the topic with an emphasis on the management with rainwater. The work also focuses on the possible alternative solutions of the given specialization. Technical part solves the installation of sanitary of this apartment building in the selected variant. It is a multiple storey building, where five floors are used for housing and two underground floors are used mostly for parking.

This diploma thesis deals with the design of sanitary and gas installations in a boarding house for seniors and their connection to existing utilities. For the whole object there will be designed operating water supply with the use of rainwater. The diploma thesis also includes the design of a sewage pumping station, grease trap, light liquid separator, infiltration equipment and rainwater tank. The theoretical part is focused on the issues of gray water and rainwater and subsequent use as operating water. Computational part and project part solves sewerage distribution, water supply and gas pipeline in the specified object. It is a partially basement object with five floors. The object includes a surgery, a cafe and a shopping place.

This diploma thesis deals with rainwater harvesting system in the company premises and the design of plumbing system in the newly built training center and storage hall. The new standard EN 16941-1 is described in the teoretical part. This standard deals with the use of rainwater. The experimental part solves the measurement of the non-potable water in this area. In the practical part, the acquired information is applied to the newly built object in the company premises. A project is created in the form of a technical report and drawing documentation for the use of rainwater and plumbing system.

The master thesis deals with sanitation installations and gas installations in the new multifunctional building situated in Kroměříž. The theoretical part is focused on analysis of the topic. It describes in detail possibilities of rainwater management and it compares its design by both valid standarts and valid regulations.
