The Far Eastern Plaza's air-conditioning system uses lower-priced nighttime off-peak electricity to produce 1,500 tons of ice which is held in an ice storage tank that takes up an entire floor of the building. Chilled air is then pumped into rooms during the day. No air conditioner compressors are needed, saving some NT $ 2.5 million in electricity bills a year.
