Abstract: One of the largest water consumers among public institutions, hospitals are characterized by water usage for various functions. Therefore, the nuanced water use requires a special methodology to determine the hospital water conservation efficiency. Based on the method of “water consumption-influencing factors in the base period”, we constructed a model for calculating the water savings amount at hospitals and demonstrated its applicability by exploring two case studies. The proposed method can help hospitals to accurately calculate the amount of water savings and determine their water conservation potential, thus evaluating the effects of the implemented water conservation measures, and achieving their targets.
