Our efforts on reducing environmental loads

In order to reduce loads on the environment, our facility has been furnished with a variety of features, including an "eco void" structure, photovoltaic power generation, ice/thermal storage air conditioning, rainwater use and LED lighting.
An "eco void" (an atrium placed in the center of the building) that runs throughout the building from the ceiling to the first floor takes in sunlight at the ceiling, which is then used as a source of lighting. This structure also serves the function of a ventilator to exhaust excess air and would also be used for smoke elimination purposes in the case of fire.
Ice/thermal storage air conditioning, thanks to its air-conditioning and heating system powered by ice in summer and hot water in winter, works to level electric loads and reduce heat source capacity. Ice and hot water to be used for this purpose is stored during late-night hours to take advantage of cheaper electricity pricing and is used during the day.
Rainwater use involves storing rainwater and using it for flushing toilets.
As other examples of our efforts on reducing environmental loads of our facility are presented in detail in Exhibition F on the second floor, please take a look.
