Abstract
Water saving is a key issue in rapidly developing countries, such as Vietnam, that face various water resource management challenges. This study investigated water-use patterns in a hotel in Ho Chi Minh City in Vietnam. It aimed to quantify the efficiency of water-saving devices through modeling toilet and shower usage patterns, including water consumption. The shift in hourly consumption of cold and hot water was also identified. Analysis revealed that, on average, a full toilet flush occurs 3.3 times/day, a half flush 3.0 times/day, water consumption due to shower usage is 48.1 L/day, showering time is 7.3 min/day and the shower water temperature is 37.7 °C. Shifting levels of hot and cold water use revealed high activity in the morning time and that there are two peaks, occurring in the morning and at night.
Highlights
A great deal of attention has been paid to the co-benefits of saving water
By modeling toilet usage andand water consumption, as well usage usage timeshower and shower temperature, this study valuable provides data valuable data relevant towater-saving improving time and temperature, this study provides relevant to improving water-saving strategies and comprehending thewater-saving impact of water-saving devices
The modeled values can values can be summarized as such: a full toilet flush occurs 3.3 times/day, a half flush 3.0 times/day, the water consumption from shower usage is 48.1 L/day, showering time is 7.3 min/day and the shower water temperature is 37.7 °C
Summary
A great deal of attention has been paid to the co-benefits of saving water. An important effect is that it directly reduces CO2 emissions by lowering the energy needs for operating and maintaining water and wastewater management facilities. Mechanism” (JCM) for international use, and this scheme requires the modeling of equipment use in order to quantify the effects of cold and hot water saving devices on CO2 emission reduction. Past studies conducted by the authors have produced models of toilet and shower usage in Vietnamese households [9]. It is crucial to construct a model of toilet and shower usage in a Vietnamese hotel based on real measurements and on-the-ground investigation, because many Vietnamese hotels are considering the introduction of hot and cold water-saving equipment. This report investigates the pattern of water use in guest rooms in a Vietnamese hotel and suggests a model of toilet and shower usage by quantifying and assessing the efficiency of water-saving devices
