Windy™ : A Revolutionary wind sail for Commercial Buildings
Windy is a breakthrough in technology, aesthetics, environmental impact, and return on investment. Together, this makes Windy an essential part of the energy solution for commercial buildings.
TECHNOLOGY BREAKTHROUGH
Conventional thinking held that drag-based wind devices (sails) would always be less efficient than lift-based devices (propellers and most verticals). Our breakthrough was first, recognizing that gusting, turbulent winds around buildings greatly increases the efficiency of our wind sail, then designing the most efficient vertical wind sail through world-class engineering. Beyond the wind, Windy is capable of handling both wind and solar energy production with the same inverter, providing a truly hybrid design.
AESTHETIC BREAKTHROUGH
Lift devices have small surfaces and need to rotate rapidly. Windy has broad surfaces and rotates slowly so logos and artwork are visible at all times. The surfaces can be customized for highly visible branding. The smart control system has a Continuous Mode (always turning regardless of wind speed) or ECO Mode (turns only when the wind is over 7 mph).
ENVIRONMENTAL BREAKTHROUGH
Lift devices use high RPMs and are not desirable near people due to noise, vibration and perceived harm to wildlife. Windy uses slow rotation to produce torque in a controlled manner that is quiet and no risk to birds, bats, or butterflies.
RETURN ON INVESTMENT BREAKTHROUGH
Alternative energy devices are often evaluated only as equipment. Windy not only generates electricity, but also replaces costly signage and enhances branding.

SPECIFICATIONS
Sail Height: 6 meters (19′ 7″) Sail Diameter: 4 meters (13′ 1″)
Cut-in speed: 7 mph, performance to 40 mph, and survival to 120 mph.
Sail is locked down at 40 mph.
The generator is 7.5kW to 12kW, customizable to the available wind resource.



SOLAR COMPATIBILITY
Because we know that “Wind is an Essential Part of the Solution,” our system is 100% compatible with solar power generation and comes with an initial 1kW solar array that may be expanded up to a total of 7kW.
CUSTOMIZE WITH GRAPHICS AND COLOR
Because of the large surface of the wind sail, customers may choose the color and add their logo or graphics to customize the look to blend in or stand out at their site. There is an option for the sail to rotate on its own during low or no wind periods.
THE TECHNOLOGY BEHIND THE WIND SAIL
The wind sail is designed by DARcorporation, Lawrence, KS. The sail is a composite structure produced by Molded Fiber Glass Company, Ashtabula, OH. System engineering is performed by SSOE Group, Toledo, OH. Initial control system design was completed by DEKA Research and Development Corporation, Manchester, NH.
WIND ENERGY CORPORATION
Our stand: “Every Commercial Building Can Power Itself … And Wind Is An Essential Part of the Solution.” Partnering with sustainability leaders, Wind Energy Corporation is the pioneer in harvesting wind for commercial buildings, providing weather assessment technology and a revolutionary wind sail.
