|Abstract:||CO₂ emission is a big problem in many places around the world, due to the environmental issues and climate change. Many studies found that building water systems have used a lot of energy which contribute to CO₂ emission. Particularly a significant fraction of the energy use associated with building water systems is attributable to water use in households. Thus, many places do researches and experiments to determine the relationship between the amount of greenhouse gases emissions and the water-related energy consumption. They establish simply equations and models to calculate the quantity of the CO₂ emission. Most of them focus on the reductionof the GHG emission due to the improvement of the efficiency end-use facilities. But few of them examine the CO₂ emission in different places around the world and compare the different values of the control parameters. To estimate the changes in the CO₂ emission associated with water use, the quantity of carbon emission of different places was examined by using data from previous researches. Thus, this study find several places in the world (Taiwan, Japan, Australia,etc.) and study their methods of determining the relationship between residential water demand (especially hot water usage) and the carbon emission. And then considered the regional effect of the chosen of parameters in these places and the different values they use for calculation we can determine the optimal option of chosen the control parameters. Thus, the CO₂ emission can be reduced to some extent and the quantitative potential of carbon reduction from using optimal control parameters reveals the motivation of water saving and environmental protection.|
