Windturbines in the facade. This is already reality in Chicago, America. This windturbines are located at the Chicago Greenway Parking garage. The system consists 12 paired vertical axis wind turbines, which twist like candy poles at a barber shop while harnessing moving air from the streets.
This installation shows the high innovativity and possibilities in the facade industry. The turbines are meant to provide enough electricity for all of the building’s exterior lighting and contribute excess power to the grid. The vertical-axis turbines will operate regardless of wind direction, harvesting power in winds as low as one to two mph and operating safely and silently in high wind speeds and extreme weather conditions. The southwest location of the turbines capitalize on Chicago’s northwest winter and southwest summer winds; they are estimated to generate 10,000-15,000 kWh per year.
The 11-story energy-efficient parking garage is seeking LEED certification after the developers of the project asked HOK to envision what a “green” parking garage would look like. Also included in the project is a rainwater collection system, plug-in stations for electric vehicles, and a glazed screen external wall that promotes natural ventilation. The elevator lobby of each floor also features a way-finding system to educate Chicagoans on how to live more sustainably and better protect the environment.
