Recently the interest of Energy have been increasing because of the disaster from abnormal climate. So, energy management solution have been needed. In previous research, we developed building energy information 3D visualization solution. This solution can provide many information associated energy usage and environment. but we don’t know what kind of information is critical for energy management and how to provide the information. This study is aimed to diagnosis system that provide building energy usage and environment information. Measured data, analyzed data and 3D model with energy usage information are placed for verification using Eye-tracking method. Finally it was able to identify what kind of information is more interested at depending on the occupational group. The experimental results can be used as an indicator what kind of information is important to managing building energy.
