2. www.alephnet.co.jp Aleph Networks Co.2 Outline of Visualization System 1. Realize the limitation of conventional data loggers and BEMS ・ Data should be “shown or coming into sight” rather than “going and fetching it”. ・ Show the current energy use trend in real time. 2. Purpose of system introduction ・ Motivate the working staff to involve energy- saving activity individually by showing data. ・ People should take action by themselves, not providing them with automatic energy saving control. System Outline

3. www.alephnet.co.jp Aleph Networks Co.3 Purpose of Visualization and Points of Development 【 Purpose 】 ・ Indicated information should make people take specific actions for energy saving. ・ Time spans for taking energy saving actions are various such as: →measures should be taken immediately or on the next day or in several days, in a month, or yearly target, etc. 【 Development points 】 ・ Make it visible in unavoidable manner as well as displaying desired page by operation. ・ Show targets in every screen page to give guidelines for specific energy saving actions in clear and simple expressions. → Display messages for promoting specific actions as well as the judgment about the present situation with “OK”/”NG”. Policy for Contents Display
