Design for energy saving behavior has been applied in many areas such as home energy management systems and information systems provided by utility companies. The purpose of this work is to help designers of the areas select effective persuasive strategies by considering users' differences. The work begins with screening commonly employed persuasive design strategies based on literature and analysis of existing cases for design for energy-saving behavior. Secondly, a questionnaire survey is conducted to investigate possible demographic differences on persuasiveness of the selected persuasive strategies due to different user groups. Thirdly, effective persuasive strategies for different types of target users are recommended based on the results of statistical analysis. The results could help designers choose appropriate design strategies for developing specific products or systems for different target users.
