“…Uma análise interessante é que, de acordo com Dias et al (2018), pode-se perceber, através de estudos, que o aumento de tarifas de água causa redução significativa no consumo residencial deste recurso. Santos et al (2005) defende que as possíveis ações de conservação de água vão da utilização alternativa de água, como o aproveitamento de águas de chuva e de águas cinzas, até o uso racional da água, que inclui o uso de dispositivos economizadores, medição individualizada e a conscientização dos usuários.…”

RESUMO: Os desperdícios de água doce tratada no Brasil vêm se destacando, principalmente pelos altos índice de perdas, baixa eficiência de equipamentos, e pela utilização de água potável para usos não nobres no dia-a-dia. Sendo assim, o aproveitamento da água de chuva para fins não potáveis apresenta-se como uma ferramenta para minimizar o uso deste bem. Deste modo, este trabalho tem como objetivo a análise técnica e econômica de um sistema de aproveitamento de água de chuva para uma residência. O dimensionamento deste foi realizado de acordo com a norma NBR 15.527 (ABNT, 2007). O reservatório foi dimensionado utilizando do método de Rippl. Conclui-se que o sistema de aproveitamento de água de chuva é viável técnica e economicamente, pois resultou numa redução de 18,3% no consumo médio mensal de água potável e um tempo de retorno do investimento de 7,4 anos.

The quality of the indoor environment is becoming increasingly important because people are spending the majority of their time indoors. This has led to an increased interest in the field of health and well-being of users of buildings and to the development of various assessment schemes dealing with this issue. In this study, LEED O+M Building Operations and Maintenance (hereinafter LEED O+M), BREEAM In-Use and DGNB Buildings In-Use were compared with a specialized BCS WELL that is focused on the health and well-being of building occupants. The aim of the comparison was to evaluate to what extent the selected building certification schemes (BCSs) cover the aspects of health and well-being in buildings. Based on the analysis, it was found that the observed BCSs mostly pay attention to indoor air quality, light and thermal comfort. In other areas, only certain topics are covered or the topics have a different focus. Another important finding of the study was that certain aspects that are important for the health and well-being of the occupants are not dependent only on the building design but also on the management of the building and the services provided within the building. This kind of information is especially valuable for building developers, managers and owners so they know how to improve health and well-being in a building. The present study provides them with a comprehensive overview of the certification schemes that are widely used in current practice.

“…The monthly water consumption (r = −0.342, p < 0.05) and the per capita water consumption (r = −0.233, p < 0.10) tend to decrease when the household is rented or financed (Figure 9). Dias, Kalbusch, and Henning [30] showed that the higher the percentage of tenants in a multifamily building, the lower the consumption was. These results can indicate that those who have expenses with rent and financing tend to save more in water consumption, since in Brazil, expenses such as water and energy bills are the responsibility of the renting resident and not the owner of the residence.…”

This study aims to identify the factors that may influence water consumption in single-family households in the city of Joinville, Southern Brazil. Through questionnaires, data were collected from 108 households in several neighborhoods of the city. The questionnaires contained open-ended and closed-ended questions involving the surrounding infrastructure, socio-economic and demographic characteristics, constructive characteristics, installed plumbing fixtures, and water-use habits, totaling 57 variables. The independent variables were correlated to monthly water consumption (m3/month/household) and per capita consumption (liters/person/day) of each household. The statistically significant variables that affected households water consumption were related to demographic characteristics such as number of residents and educational level, construction features (i.e., number of bathrooms, building age, and built area), the presence of water-efficient appliances and water conservation habits. The results obtained can contribute to the development of new studies on water consumption and sustainable policies and awareness on the importance of water conservation.
