Urban wind turbines are recommended for installation on a building roof-top to capture more wind energy. It is critical to decide an exact location for the wind turbine installation on the roof-top area. In this paper a joint probability density function of wind speed and direction is proposed as a statistical model for wind distribution, and a

READ MOREThe WindBox is a compact module combining a shrouded turbine (4m², 1.60m high) with two photovoltaic solar panels on top. Positioned on the edge of buildings, the WindBox benefits from accelerated winds and good exposure to the sun. Installed power is 1,500 W for the wind turbines and 750 Wp for the solar panels.

READ MOREThe turbine vent. While a turbine looks a little complex at first glance, it''s actually very simple. Much like a window, this round vent is powered by the wind. It houses a circular fan that''s very sensitive to breezes. When the wind blows the right way, it turns the fan, which in turn draws up air from the attic and disperses it.
READ MORERooftop wind turbines placed on buildings are inefficient because they are in "the shadow of the winds," said Alexander Suma, founder and CEO of IBIS Power, a renewable energy company in the Netherlands. Turbulence around the rooftop makes energy production inefficient. The unit has internal wind turbines and solar panels on
READ MOREPossible integration location for a wind turbine on tall buildings (a) Large size and (b) Small-sized wind turbines on top and side of the building (Park et al., 2015). Deploying wind turbines between two buildings and integrating turbines in building openings are fascinating possibilities regarding micro wind energy generation.
READ MOREA wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
READ MOREAnother big drawback to building-integrated wind is that even though it''s often windy on top of buildings, that wind tends to be quite turbulent. It''s twisting around and not nearly as effective for wind

"As the wind hits those airfoils, it creates a negative pressure that sucks the wind that''s hitting the building through an internal propeller on
