Energy-Saving Visual Power

Bar Graph

Power consumption, operating hours, etc. are displayed as bar graphs. Bar graphs can be displayed in parallel, stacked or by unit, allowing you to select the graph that best suits your purpose. Target values are also displayed on the graph, making it easy to compare and manage consumption to achieve targets. Compare past usage data (daily, monthly and yearly) to see progress of energy saving measures.

Line Graph

Setting temperature, room/outdoor temperatures, etc. are displayed as line graphs. Various display methods can be selected, including unit-by-unit, item-by-item and previous day (previous year) comparisons.

Easy Tenant Support and Billing

Areas of Power Distribution, as well as time blocks (during hours, after hours, specific days) can be set by the customer. Prorations and fee data can be extracted in CSV format via LAN or USB memory, and can be converted to the customer’s preferred format.
