The Ecological Community Evaluation System (EEWH-EC) of Taiwan was proposed in 2009 and is focused on evaluating the entire community. It is a member of the EEWH family of green building assessment system. The purpose of this study is to introduce the EEWH-EC. The evaluation system includes five assessment categories: ecology, energy conservation and waste reduction, health and comfort, service function, and crime prevention. Communities can apply this system to assess themselves, determine their special characteristics, and use the outcome to implement improvements. The government can utilize the evaluation result to make policies for better and sustainable environments for citizens.
