Recognizing that small ceiling fans have remained basically unchanged for more than a century, Big Ass Fans decided to reinvent them completely. The result is the 60-inch Haiku, the Energy Star most efficient ceiling fan in the world. With the world’s only research and development facility dedicated to fan technology, the Big Ass Fan Company® has spent the last decade perfecting the science of air movement. We’ve brought comfort to warehouses, schools, and every type of large building in between. And since the residential ceiling fan hadn’t changed significantly in 100 years, we decided it was time to bring our work to your home.
