| Abstract |
| The objective of this study is to suggest effective ways to solve water shortage problems by water saving achieved from a toilet retrofitting program at Seoul National University. 35 bowls in building #35 were changed from conventional bowls to high efficiency bowls. Water saving effects were analyzed after 8 months of water saving and benefits data collection. The flow amount was decreased from 238.73 to 94.38 for a month. Assuming that all 8,176 bowls are changed in Seoul National University, amount of 378,237 water can be saved and initial investment will be returned in years. Moreover, due to conserve electricity 239 ton of carbon dioxide are expected to reduce. To maximize benefits, social system improvements such as providing incentives from suppliers is necessary |
