“ We love our Big Ass Fan! We get better air movement in the giraffe house than anywhere else in the zoo. Michael Jones, Animal Curator
Giraffes are accustomed to warm temperatures year-round, so it was no surprise the caretakers at Kentucky’s Louisville Zoo found it difficult to create a comforting environment for them in a state known for its distinct seasons. With 40-ft (12.2m) cathedral-style ceilings, the Zoo’s Giraffe House constantly ran boilers to warm the animals in cold months. In the summers, the Giraffe House relied on two standard 60-in (1.5m) ceiling fans, but they were unable to move large enough volumes of air to keep the animals comfortable. An energy-efficiency audit suggested the Zoo could significantly reduce its yearly energy consumption, so the leadership went in search of a tall-order solution.
Energy consultants Johnson Controls pointed the Zoo to Big Ass Fans®. The company replaced the two unproductive fans with a 12-ft (3.7m) Powerfoil®X2.0. In winter, the fan moves large volumes of warm air off the ceiling, where it pools, to create a uniform temperature. Because the boilers now run less, the Zoo is saving up to 30% in operating costs. During summer, the Powerfoil X2.0 is in constant use to dispel flies, eradicate unpleasant odors and create a cooling effect of up to 10°F (5.6°C). “The fan is fantastic,” said Giraffe Keeper Karen Veleta. “It not only conserves energy, it contributes to the welfare of the animals.”
