Japan's Green Convention Facilities

We face a host of environmental challenges today, including global warming and the heat island effect. Green conventions or green meetings—particularly for international conferences—are becoming increasingly important as we work to establish sustainable societies for the future. In this issue, we introduce two convention facilities in Kyoto and Osaka that are making efforts to keep our environment clean and green.

Kyoto International Conference Center:The Kyoto Protocol was adopted during the Kyoto Global Warming Conference (COP3), which took place at the Kyoto International Conference Center. Particularly with this type of conference, we believe it is important for conference centers to be environmentally friendly. Therefore, we installed a co-generation system and water recycling system on the property.

Co-generation system

A natural gas co-generation system is used to generate the electricity and heat needed to meet the center’s power and air-conditioning needs.
Two 600-kw gas engines for continuous power generation are located beneath the Conference Hall. They operate in conjunction with the commercial power grid, supplying power throughout the ICC Kyoto complex.
Hot water produced when cool water is run through the gas engines, plus steam from exhaust gases, are used to run air-conditioning systems and supply hot water to the site. Because the system burns natural gas, it emits mainly carbon dioxide and nitrogen oxide, with almost no sulfur oxide and very little other impurities. The impact on the natural environment is reduced even further by the adoption of a three-way catalyst method to reduce nitrogen oxide output.

Water recycling system

In view of the need to reuse our limited water supply and to ensure the availability of water for use in case of disaster, day-to-day waste water and water from the gardens’ Sachiga-ike and Sakura-ike ponds is purified and used to clean restrooms.

Pond water is purified with a new system that uses ultraviolet disinfection, ozone oxidative decomposition, and high-density filtration. These processes ensure the safety of the water and leave no harmful residues that might damage ecosystems.

Sheraton Miyako Hotel Osaka: as part of efforts to conserve energy and reduce carbon dioxide emissions to reduce environmental impact, the Sheraton Miyako Hotel Osaka installed a photovoltaic system with approximately 100-kW battery capacity on the roof of the banquet room of its Osaka branch. The 1,200-m2 system is the largest among Japan’s hotels, and is expected to generate 100,000 kWh annually while reducing carbon dioxide emissions by about 35 tons per year.
