BLDW's innovative and patented turbine design is ideal for urban settings. The turbine creates reliable, cost-effective, clean and on-site renewable electricity with little building modification required. Building Turbines' horizontal-axis wind turbines easily mount onto commercial buildings with flat roofs and turn historically dead space into power producing real estate. 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.
