Mashing up multiple logs in home network system for promoting energy-saving behavior

Recently, resource monitoring systems to visualize energy consumptions such as electricity and gas for home users, are developed. In the home, user´s daily behavior affects total amount of consumption energy significantly. Such monitoring systems aim at making a user conscious of energy-saving behavior. Most of conventional systems provide summarized data on consumed energy to a user. From the data, a user can know result of excess consumption of the energy. In such visualization, however, it´s difficult to investigate the reason by which energy consumption became excessive for users. In our research, we propose mashing up multiple home network system logs to improve use´s daily behavior in the home. Especially, we illustrates mashing up data on energy consumption, appliance controller, and environmental sensor, which is usable for discovering the futility about user´s behavior concretely.
