Building Turbines

BT Mission Statement: To provide clean, renewable, reliable and cost-effective on-site generation of electricity for commercial buildings via our rooftop mounted horizontal-axis wind turbine (HAWT).

Building Turbines, Inc. is an Austin-based early phase renewable energy corporation focusing on designing and manufacturing revolutionary rooftop mounted wind turbines. The innovative and patented Building Turbines design is ideal for urban settings and creates reliable, cost-effective, clean and on-site renewable electricity. Building Turbines’ horizontal-axis wind turbines (HAWT) easily mount onto commercial buildings with flat roofs. 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. There are two full-sized working prototypes installed on the Building Turbines’ headquarters building in Austin, Texas.

The wind has been harnessed to deliver energy for centuries. Today, wind generates electricity that powers millions of American homes and businesses and is one of the fastest-growing sources of clean and renewable energy. Taking advantage of this abundant natural resource to generate electricity helps meet the world’s growing energy demands while improving our over-all energy stability, protecting our environment and saving real bottom-line dollars in the process.
