Finally, large ceiling fans are installed in every room, even those using air conditioning. Ceiling fans ensure that even in the absence of the necessary breezes, the airflow needed to feel comfortable in the room is provided for the users. This solution significantly reduces the amount of energy consumed. The overall consumption of the ceiling fans and the split system (the latter used to cool the technical rooms) is only 3.7kWh/m².yr compared to a classic air conditioning system in a standard building consuming 80kWh/m².yr.
Calvin D. MacCracken
MacCracken is best known for his work in energy storage and ice rinks. He developed the IceBank® energy storage system, a form of thermal energy storage used to cool buildings by making ice at night when electricity rates are less expensive. IceBank® energy storage functions like a battery for a building's air-conditioning system. IceBank® saves dramatically on the cost to cool buildings by reducing a building's on-peak use of electricity. The IceBank ice battery system uses standard cooling equipment plus an energy storage tank to shift all or a portion of a building's cooling needs to off-peak, nighttime hours. During off-peak hours, ice is made and stored inside IceBank energy storage tanks. The stored ice is then used to cool the building the next day. IceBank® offers a critical service to grid, since air-conditioning is the main culprit behind spikes in peak electrical demand. This on-peak reduction decreases the need to build new power plants or turn on expensive “peaker” power plants. Over 1GW of IceBank energy storage is used in over 4,000 installations in 60 countries for commercial buildings, schools, government buildings, hospitals, hotels and retail.
