Big Ass Fans are, as their name suggests, a producer of very large fans. They’re used everywhere from dairy barns to art galleries to outdoor public installations like Wendy, HWKN’s star-shaped pavilion for MoMA PS1’s summer Warm Up series. They also make residential models, like Haiku, the latest product in their line up. Once you get over the eye roll-inducing slogan—Haiku: Poetry in Motion—it’s a really incredible product. According to Energy Star it’s the world’s most efficient residential ceiling fan, and even exceeds their efficiency requirements by 450 to 750 percent. Whereas most fans use 90 to 100 watts, the Haiku uses just two to 30 watts, costing an average of $5 per year.

The fan blades are made from Moso bamboo, a super-strong, fast-renewing material that’s harvested sustainably in China and handcrafted in Kentucky. Before the bamboo is dried and finished, each individual stalk is inspected for imperfections. Haiku also comes in a glass-infused matrix composite in black or white.

Either way, black, white, or bamboo, the cool-running motor is completely silent, even on the highest setting (there are ten in all). There’s also a brand new mode called the Whoosh, which pulses to simulate natural variations in air flow. “Human thermal receptors have peak sensitivity to wind gusts that vary by 0.47 Hz; Providing air movement with this variation can increase perceived cooling by up to 40 percent.”

So far Haiku has won a handful of awards, including a red dot design award for product and bronze in the International Design Excellence Awards (IDEA) in the living room and bedroom category.

Haiku in bamboo retails for $995.
