Este estudo tem como objetivo monitorizar as soluções integradas do projeto inovação
“HydroSAAP” e estabelecer medidas complementares de eficiência hídrica na residência de
estudantes Gulbenkian do Instituto Politécnico de Bragança.
Os chuveiros e torneira de cozinha, hidricamente eficientes e instalados pelo projeto,
mostram resultados satisfatórios após monitorização e aplicação de um questionário aos
utilizadores. Os resultados à qualidade da água da chuva, captada pelo sistema de
aproveitamento de águas pluviais com capacidade de 1,5 m3, indicam que pode vir a cumprir
os requisitos para usos não potáveis. Contudo, a água das primeiras chuvas, após um longo
período de seca, deve ser descartada. Concomitantemente, foram propostos sete cenários
integrados e complementares, para estudar a eficiência hídrica na residência.
Resulta que, com uma possível substituição das torneiras de lavatório, autoclismos de
bacias de retrete e fluxómetros de mictórios, aliada ao aproveitamento de águas pluviais para
rega de zonas verdes e lavagem de pavimentos, é estimada uma poupança anual de água de
60,63 m3 (7,38%), com investimento inicial de 1627,68 € + IVA, redução na fatura anual de
água de 490,89 € + IVA, e tempo de retorno do investimento de 3,32 anos.
Desta forma, para além de promover a redução do consumo de água potável na
residência de estudantes, e a adaptação e minimização dos efeitos resultantes das alterações
climáticas, este estudo pode contribuir para a sustentabilidade do ambiente construído, podendo
ser replicado em investigações futuras.
This study aims to monitor the integrated solutions of the “HydroSAAP” innovation project and to establish complementary water efficiency measures in the Gulbenkian Student Residence at the Polytechnic Institute of Bragança. The water-efficient showers and kitchen taps installed by the project show satisfactory results after monitoring and applying a survey to users. The results regarding the quality of rainwater, collected by the rainwater harvesting system with a capacity of 1.5 m3, indicate that it can meet the requirements for non-potable uses. However, water from the first rains, after a long period of drought, must be discarded. Concomitantly, seven integrated and complementary scenarios were proposed to study water efficiency in the residence. Considering the possible replacement of washbasin taps, flushing cisterns, and urinal flow meters, combined with the use of rainwater for irrigating green areas and washing floors, an annual water saving of 60.63 m3 is estimated (7.38%), with an initial investment of €1627.68 + VAT, a reduction in the annual water bill of €490.89 + VAT, and an investment payback period of 3.32 years. In addition to promoting the reduction of potable water consumption in student residences, and the adaptation and minimization of the effects of climate change, this study can contribute to the sustainability of the built environment and can be replicated in future research.
