In this study, we propose a standardized design method using dimensionless design factors (specific catchment area, specific storage capacity) for the catchment area and storage tank capacity for the installation of rainwater facilities under rainfall conditions in Korea. As a result of simulating the water-saving efficiency of rainwater facilities that supply toilet flushing water in 17 office buildings in the metropolitan area, it was confirmed that the specific catchment area is a major design factor affecting the water-saving efficiency. In order to achieve the annual water-saving efficiency of 30%, it was evaluated that the specific catchment area and the specific rainwater storage capacity required 0.2 or more, respectively. In addition, when looking at the monthly water-saving efficiency, it is estimated that 100% of the required water demand can be supplied for up to three months from July to September under optimal conditions. Due to the annual rainfall variation, there is a limit to using all of the collected rainwater as toilet flushing water. Consideration of temporary use for other purposes should be reflected in the design stage of the building considering the characteristics of the target building and local conditions. In the future, follow-up studies are needed for field verification of dimensionless design and efficiency evaluation based on water supply and demand.
