Decision Supporting System for Rainwater Harvesting Systems in the Green Campus Project of Taipei

摘要

Rainwater harvesting systems (RWHSs) ease urban water shortage and have been adopted in the Green Campus Project in Taiwan. However, the spatial-temporal variance in precipitation significantly influences the hydraulic and economic performance of RWHSs, and a decision supporting system is essential for the large scale evaluation. This study proposes a simulation-based spatial system (SBSS) incorporating economic analysis for supporting the design making in RWHSs. A case study is presented, which applies the method to the rooftop RWHSs of university buildings in the Green Campus Project in Taipei Area. Compared with the traditional generalized metbod, the SBSS has enhanced the information value for decision making. Therefore, the SBSS is a useful tool for prompting RWHSs in large scale.
