This paper investigates the possible benefits and effects of energy-saving attitude, subjective norm, perceived behavioral control, and the behavioral intention of employees on habits in the workplace. The total sample size was 322 respondents. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were used for the statistical analysis. The analytical results indicate that energy-saving attitude and perceived behavioral control correlate positively with the employees’ energy-saving habits. However, the subjective norm does not have a positive correlation with employees’ energy-saving habits. In addition, an examination of the mediating effect reveals that employees’ behavioral intentions are a significant mediator for energy-saving attitude, the subjective norm, and perceived behavioral control of the employees’ energy-saving habit. Moreover, this study provides a framework for the management of energy-saving in the workplace, and closes with a discussion on the theoretical and practical implications of the research findings.
