Resumo: | The objective of this study is to analyze the economic feasibility of implementing a rainwater catchment system to serve non-potable uses in vertical residential buildings in the city of João Pessoa, state of Paraíba, Brazil, and assess the willingness of the city's population to pay a higher price for a property that has this rainwater catchment system. The first hypothesis considers a variation in the number of floors, ranging from 5 to 30. The second hypothesis considers a variation in the reservoir volume. The volumes considered and tested were 15m³, 25m³, 45m³ and 65m³. Thus, 104 scenarios were created. To verify the population's interest in rainwater harvesting systems and the willingness to pay extra for these systems, a survey was carried out via google forms, for about 70 people. Overall, 79.8% of the scenarios have B/C greater than 1. To the 15m³ reservoir, which presented a greater economic attractiveness, 92.31% of the alternative scenarios B/C greater than 1. The 65m³ reservoir has only 65.38% of the B/C values greater than 1. The best performance was achieved for the scenario of 21 floors and 15m³ reservoir, with the B/C of 1.96, NPV of R$24,446.92 and payback period in 9.3 years. The application of the forms revealed that 96.6% of the population is interested in acquiring a property with the development system and that 57.1% are willing to pay up to 2% more than the property's value. |

La primera hipótesis consideró la variación en el número de pisos, que van de 5 a 30. La segunda hipótesis consideró la variación en el volumen del embalse. Los volúmenes considerados y ensayados fueron 15m³, 25m³, 45m³ y 65m³. Así, se crearon 104 escenarios. Con el fin de verificar el interés de la población en los sistemas de captación de agua de lluvia y la voluntad de pagar extra por estos sistemas, se realizó una encuesta a través de formularios de Google, a unas 70 personas. El 79,8% de los escenarios tiene B/C mayor a 1. Al embalse de 15m³, que presentó mayor atractivo económico, el 92,31% de los escenarios tenía B/C mayor a 1. El embalse de 65m³ presentó solo el 65,38% de los valores de B / C superiores a 1. El mejor desempeño alcanzado fue para el escenario con 21 pisos y un embalse de 15m³, con un B / C de 1,96, un VPN de R $ 24.446,92 y un período de recuperación de 9,3 años. La aplicación de los formularios reveló que el 96,6% de la población está interesada en adquirir una propiedad con el sistema de desarrollo y que el 57,1% estaría dispuesto a pagar hasta un 2% más del valor de la propiedad.O objetivo deste estudo é analisar a viabilidade econômica da implantação de um sistema de aproveitamento da água de chuva para atender a usos não potáveis em edificações verticais do tipo residencial na cidade de João Pessoa-PB, bem como avaliar a disposição da população da cidade em pagar um valor mais alto por um imóvel que possua esse sistema de captação de águas pluviais. A primeira hipótese considerou a variação no número de pavimentos, variando de 5 a 30. A segunda hipótese considerou a variação no volume do reservatório. Os volumes considerados e testados foram 15m³, 25m³, 45m³ e 65m³. Dessa forma, foram criados 104 cenários. Para verificar o interesse da população em sistemas de captação de água de chuva e a disposição em pagar a mais por esses sistemas, foi realizada uma pesquisa via formulários google, para cerca de 70 pessoas. Em 79,8% dos cenários apresentaram B/C maior que 1. Para o reservatório de 15m³, o que apresentou maior atratividade econômica, 92,31% dos cenários apresentaram B/C maior que 1. O reservatório de 65m³ apresentou apenas 65,38% dos valores do B/C maior que 1. O melhor desempenho atingido foi para o cenário de 21 pavimentos e reservatório de 15m³, com o B/C de 1,96, VPL de R$ 24.446,92 e período de retorno em 9,3 anos. A aplicação dos formulários revelou que 96,6% da população tem interesse em adquirir um imóvel com o sistema de aproveitamento e que 57,1% teriam disposição em pagar até 2% a mais do valor do imóvel.Research, Society and Development2021-07-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1765510.33448/rsd-v10i8.17655Research, Society and Development; Vol. 10 No. 8; e49010817655Research, Society and Development; Vol. 10 Núm. 8; e49010817655Research, Society and Development; v. 10 n. 8; e490108176552525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17655/15715Copyright (c) 2021 Byanca Evelly dos Santos Martins; Lenore Karla Medeiros Menezes; Cindy Deina Farto; Gilson Barbosa Athayde Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMartins, Byanca Evelly dos Santos Menezes, Lenore Karla MedeirosFarto, Cindy Deina Athayde Junior, Gilson Barbosa2021-08-21T18:46:59Zoai:ojs.pkp.sfu.ca:article/17655Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:56.988545Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
