Okamura Corporation, a Japanese machinery and construction firm, announced on May 10, 2010, that it has started to sell a power consumption visualization system “OFFICE NAVI”. By connecting electric power meters to the power distribution board in the office, the OFFICE NAVI quantifies and graphs on a monitor where and how much electric power is being consumed. The system was developed in cooperation with the IT company IP Square.
The visualization system consists of a touch-panel monitor called the Smart Station, electric power gauging meters, and a local server. The power gauging meter has several functions, including measuring current power consumption and reporting to the Smart Station when the consumption exceeds a target level. The local server controls the Smart Sensors and accumulates the data. Graphing the accumulated data helps to identify any wasted electricity and room for improving efficiency.
Since the amendment of the Act on the Rational Use of Energy (known as the Energy Conservation Law) took effect in April 2010, the number of companies being regulated has increased. For such companies, the system provides optional software to prepare regular reports, which comply with the Act, as required by the Ministry of Economy, Trade and Industry (METI).
