Kelley Company offers its High Volume Low Speed Fan series (or HVLS) designed to provide energy-efficient, cost-effective cooling and heating. Fans use physics to slowly move a large column of air, creating a horizontal floor jet that circulates air in large spaces, according to the company. Fans can be used in facilities seeking LEED Certification credits, and include the Fusion and Orbit series.
