A system for converting wind energy to electrical energy for use in a building. Conduits positioned within the building have end portions open to exterior wall surfaces of the building. Wind deflector mechanisms positioned at the end portions of the conduits direct wind from the exterior wall surfaces of the building into the conduits and allow wind to exit the conduits. Wind flowing through the conduits impacts venturi elements and wind collector devices positioned within the conduits. The venturi elements are pivotally mounted within the conduits to accelerate the wind towards the wind collectors regardless of in which direction the wind flows, thereby causing the wind collectors operatively associated with a wind turbine device to rotate. Wind collector rotation produces mechanical energy that the wind turbine device converts to electrical energy for the building.
