  • Teruyoshi Minaki*1

*1:Executive Vice President, Chief Green Officer,Industrial Automation Business Headquarters

Global warming is causing sea levels to rise and abnormal weather patterns. Humankind is also facing other serious problems including the depletion of fossil fuels, forests, water, and food, and must reduce the use of hazardous chemicals for the sake of humans and the natural environment. To solve these problems and achieve a sustainable society, people around the world must work together immediately to conserve energy and preserve the environment. This paper describes the global situation relating to these difficulties, and Yokogawa's efforts to solve the problems. Yokogawa's products and solutions are also outlined.

In order to reduce operating costs, factories consuming large amounts of energy use boiler, turbine, and generator (BTG) systems to generate and distribute electricity and steam powered by commercial fuel and energy recovered in their premises. Because a BTG plant deals with huge amounts of energy, there is much room for improving energy-saving efficiency. This paper describes an application of optimal balance control for electric power and steam in BTG plants and its features. This control was achieved with Yokogawa's Exasmoc multivariable model predictive control package.

*3:Green Factory Solutions Business Center,Industrial Automation Business Headquarters

Mercian Corporation has established an environmental load management system at its Yatsushiro Factory by using Yokogawa's Enerize factory energy management system. The system is intended to manage data not only on energy consumption but also on the environment relating to production activities such as the amount of water consumed in the factory. This paper describes the successful introduction of this system.

Energy Conservation and Environmental Improvement in Hospitals
- ESCO Project at Okinawa Hokubu Hospital -

  • Hideki Kanai*1
  • Hiroshi Takahashi*1

*1:Green Factory Solutions Business Center,Industrial Automation Business Headquarters

Environmental preservation is an important corporate social responsibility (CSR) activity as well as financial indicator, not only in industry but also in local governments. This paper reports an example at Okinawa Hokubu Hospital. This hospital introduced the energy service company (ESCO) project and succeeded in reducing expenditure and environmental burden by implementing energy-saving measures while also considering the safety and hygiene of the facilities. In the business model of the ESCO project, service providing companies supply customers with energy-saving equipment, cover the installation cost by reducing utility costs, and create a surplus for customers. This project won the Chairman's Prize, the Energy Conservation Center, Japan (in the support service section in organization category) in the 2009 Energy Conservation Awards sponsored by the Ministry of Economy, Trade and Industry.

Using IT to Eliminate Energy Waste in Production Lines

  • Tetsuro Tanaka*1
  • Shozo Kono*1

*1:Kofu Factory Administration Dept.,Yokogawa Manufacturing Corporation

The Kofu factory of Yokogawa Electric Corporation has been working on conserving energy since the 1990s. In October 2009, it won the Minister of Economy, Trade and Industry Award in the Green IT Award 2009, which was held by the Green IT Promotion Council. It was commended for introducing an energy conservation management system which, combined with the production management system, visualizes the amount of energy consumed per product while securing quality, delivery time and safety; as well as for ongoing improvement activities, monitoring energy consumption by each line, and everyday electricity control. This paper describes these award-winning energy conservation activities, focusing on changes of CO2 emission, Yokogawa's energy-saving IT products, and introduction of the benefit principle which makes employees more energy-aware.
