Resumo(s)
This research is focused on the water usage patterns in two student residences—one for male
students (Residence I) and the other for female students (Residence II). Surveys and measurements
of flushing cisterns, taps, and shower flows were conducted to understand water use behaviors.
Scenario 1 proposed replacing washbasin and kitchen taps and installing flow reducers in showers,
while Scenario 2 combined Scenario 1 with a rainwater harvesting system for recharging flush cisterns.
Showers were found to be the most water-consuming devices, accounting for 46% and 61.41% of water
consumption in Residences I and II, respectively, followed by kitchen taps (31.51% in Residence I and
11.52% in Residence II). The flushing cistern consumption was 7.02% in Residence I and 13.22% in
Residence II. The implementation of Scenario 1 anticipates a 13% reduction in total water consumption
in Residence I and a 10% reduction in Residence II. The reduction in hot water consumption would
result in a decrease in annual electricity consumption by 27.8% and 23.06% in Residence I and II,
respectively. With the implementation of Scenario 2, the total potential water savings for Residence I
could increase to 19.98%, and for Residence II, it could rise to 23.17%. The proposed measures aim to
enhance water sustainability in these buildings and can be replicated elsewhere.
