Prospects for Using Vertical-Axis Wind Turbines in the Context of Current Urban Development

The issues regarding the use of small vertical-axis wind turbines in urban conditions are considered. An assessment of urban density and the area available for wind turbine place-ment has been made. Numerical simulation of airflows around the building has been performed, and the wind flow amplification factor over the building roof has been estimated depending on house orientation according to the cardinal points. The annual energy generation for the roof-mounted wind turbine has been determined, and the optimum building orientation relative to the cardinal points for the city of Penza (Russia) has been specified. The potential for urban wind energy has been evaluated.
