BTI System Advantages

The uni-directional design rests on HVAC-style curbs and is mounted along the roof's edge next to the parapet wall. The turbine takes full advantage of what is called a "parapet vortex" which naturally occurs as wind accelerates up the side of a building and crests over the roof top edge. The axis of the turbine is centered in this vortex capturing maximum electrical power generation capability from the wind.

• BT’s design has one awarded patent, two patents pending, and more on the way
• The BTI turbine has an approx. 10’ x 27.5’ footprint and the system weighs approx 1,400 pounds as a complete system
• Patented design captures maximum rotational wind from natural vortex created at roof top edge
• Horizontal axis design is more effective when mounting to building due to no mast or pole
• Horizontal blades can be customized with full-color graphics and company logo (as well as the ‘augmenter’ that sits over the edge of the rooftop to guide the wind into the turbine)
• Design allows for secure mounting on roof with minimal modification (no poles or costly roof modifications)
• Well-suited for the urban environment (low profile, ease of installation, appealing design)
• Low center of gravity with strong, robust square steel tubing (frame) design for rooftops which results in almost no vibration or noise
• Installation can be accomplished without the use of expensive helicopters (easily assembling unit(s) on the roof top)
• Scale-able design
• Can add turbine units per available space on roof
• All turbine units can share wiring and/or storage with each other
• Turbines can be combined with solar (PV) cells and they can also share ‘system’
