Narita International Airport Central Heating and Cooling Plant

At Narita International Airport, a central heating and cooling plant provides chilled and hot water for air conditioning and heating to about 50 facilities inside the airport. As part of its ongoing efforts to conserve energy, Narita International Airport initiated an energy service company (ESCO) project to introduce a system that would ensure optimal heat source operation. The system, which provides guidance for optimally starting and stopping various heat source equipment based on the demand projections calculated from weather information, has resulted in energy cost savings far exceeding the targets.

Narita International Airport is a hub airport and, for international travelers, a representative of Japan. Since the number of inbound tourists has rapidly increased in recent years, Narita’s presence as an air gateway welcoming international passengers to Japan has also increased.

Since the airport opened in 1978, it has been working on measures to lessen the local environmental impact caused by the airport’s operation and to help preserve the Earth’s environment and contribute to establishing a sustainable society.

“In recent years, we have been searching for a way to reduce the energy of the central heating and cooling plant, which is a large energy plant providing chilled and hot water for air conditioning and heating to about 50 facilities located in the airport, such as passenger terminals, cargo buildings, etc.,” explains Akira Kondo, a manager in the Facilities Management Department of Narita International Airport Corporation.

“We had already introduced energy-saving equipment and cogeneration technology along with operational changes, but more drastic measures were needed to achieve further energy savings,” adds Tetsuya Yamamoto, a section manager in the Mechanical Systems Department of Narita Airport Facilities Corporation.
