Man Cave, Longmont, Colo.

David Vanderpool renovated his 18-foot-high, L-shaped storage unit from Garage Town USA to include a three-person office for his engineering firm, and to double as his man cave. With an interior made entirely of metal, no windows and poor insulation, the 1,000-square-foot space was expensive to heat. Aluminum siding, steel bar joists and metal roof decking is par for the course within storage units, but Vanderpool added his own element of functional style with a 10-foot diameter aluminum Isis fan from the Big Ass Fan Co. to destratify the air.

While often associated with summer cooling, large diameter fans are also capable of destratifying a space in the winter, reducing energy consumption by as much as 30 percent. Heated air from a forced air system (100-125 F) is less dense than the ambient air (65-75 F), and hot air naturally rises to the ceiling. By slowing the speed of large diameter, low speed fans to 10 to 30 percent of its maximum rotations per minute, warm air is redirected from the ceiling to the occupant level, increasing occupant comfort and reducing the amount of heat loss through the roof. "I can tell you generically that [my energy use] has decreased since I put in the fans," Vanderpool said.


With Colorado winter temperatures averaging in the teens, Vanderpool said he generally sets his thermostat to 65 F. He was in the space for a year before installing the fans. Equipped with very limited heating capacity and the resulting high energy bills, Vanderpool said, "[The fan] does a really good job of evening out the temperature, making it much more comfortable."
