WINTER ENERGY SAVINGS AND DESTRATIFICATION
Fans aren’t just for cooling. In the winter, heat rises and can get trapped at the ceiling, leading to huge temperature differences and massive heating bills. In a space suffering from stratification, the floor temperature might be 18ºC while the ceiling might be 29ºC. With a large fan continually mixing the air, the temperature at floor level will even out and less heating will be required.
LEADING THE WAY IN INNOVATION AND RESEARCH

Big Ass Fans has developed its own research and development (R&D) facility in the US, where it conducts extensive research and testing. This laboratory is a LEED® Gold certified facility dedicated to developing energy-efficient fans. No other facility exists to meet the unique requirements and challenges of testing and developing new innovations. At this high-tech facility,
and a more effective use of heating. By using more energy efficient products like Big Ass Fans, business owners and operators can be assured they are taking the right steps to help protect our environment and lessen their carbon footprint. To find out more about how Big Ass Fans can help
Big Ass Fans works toward developing the best products possible for use in passive design, which works with the climate, not against it. HVLS fans contribute to passive design by helping reduce greenhouse gas emissions through reduced reliance on air conditioning
