A Monte Carlo model for evaluating the carbon reducing impacts of the water efficiency labelling scheme on showers for bathing in Hong Kong

Brief:

In Hong Kong, the voluntary Water Efficiency Labelling Scheme (WELS) on showers for bathing is a shower water conservation initiative of the HKSAR Government. As shower water consumption has been identified as a potential area for carbon emissions reductions,

this study proposes a Monte Carlo model for evaluating the carbon-reducing impacts of WELS on showers for bathing. The simulation results indicate that full implementation of WELS rated showerheads with k􀁤4.02 can reduce water consumption by 37%, energy consumption by 25% and carbon dioxide (CO2) emissions by 26%.
