On the potential yield of wind turbines on high-rise buildings

Urban wind energy has intrigued some investments and applications over the last decade. However, most have been unsuccessful, in many cases leaving behind non-rotating turbines built environment. Research on urban also lacked providing a reliable description of local flow features small are placed in, positioning strategy is mostly based empiricism. This study uses data from tunnel test pattern above roof high-rise buildings to estimate potential yield installed various configurations. The collected at height 12 m flat under directions. capacity factor medium-size horizontal axis turbine calculated using power curve available literature. resource mean speed as measured with hot-wire anemometry. annual production configurations climate for Firenze (IT) orientation building respect main winds. A rather large variability output roof-farm was found chosen configuration.
