The goal of this study is to achieve sustainability environment. According to our previous study in the nine Indicators of Taiwanese Green Building, and the Canada GBTools evaluation, combined with Taiwan’s leisure farms, we simulate evaluation factors of sustainability for the practical environments in Taiwan’s leisure farms. We then classify the evaluation factors according to its tendencies and create an expertise questionnaire using these tendencies. Through the results of the expertise questionnaires, we understood how much the experts valued ecology, energy, resource, society, and economy. We then further analyze the cause of the varying degree of attention paid to each category according to its attributes . SPSS statistic software is used as the analytic tool. Through factor analysis and the deletion of factor loading, this study attained four kinds and nine evaluations as well as 29 evaluations points: "perfect environment", "resources management ", "energy efficiency management". In addition, "complete plans and evaluations", "environment workload", "environment plans", the conclusion is that the most valued points for the business are: "environment plans", "environment workload", "perfect environment". However, the most valued points for the government are: "perfect environment", "resources management ", water resources and green materials. As for scholars, the most valued points are: "perfect environment", "environment workload", "using local renewable materials" as well as "environment plans". Analysis of Variance, the conclusion is that the most valued points for the government and scholars are: "natural sounding usage", "legality of base selection", "effectiveness in pollution process", "light efficiency control management systems", "simplified interior design". Finally, LSD analysis attained five evaluation points: "natural sounding usage", "legality of base selection", "effectiveness in pollution process", "light efficiency control management systems", "simplified interior design". The result of this study shows that implementations would be much easier if the necessary equipments and space were put into consideration during the planning stage of recreational farms. Lastly, this study suggests leisure farms choose their operating method carefully. The operating method should meet the nature of leisure agriculture; it should also consider utilizing the sustainable development assessment indicators and relevant decorations in the future. If a correct operating method is chosen, it will facilitate an environmentally friendly leisure farm. Keyword: Recreational Farm, Sustainability, Factor analysis.
