PROBLEM TO BE SOLVED: To improve a rooftop wind state of a building so as to be suitable for wind power generation, and to effectively utilize a rooftop site.SOLUTION: In a rooftop wind collection structure of a building for a wind power generator, a lower wind collection structure and an upper wind collection structure having approximately the same shape as a rooftop of the building in a top view, are disposed on the rooftop of the building. The lower wind collection structure covers a building rooftop part with a gentle circular arc shape where a projecting portion having a flat and horizontal face at its central portion, faces upward, the upper wind collection structure is disposed above the lower wind collection structure, and has approximately a symmetrical shape in a vertical direction with respect to the lower wind collection structure, and at least one or more vertical shaft-type wind power generators are disposed in a space surrounded by flat faces of the lower wind collection structure and the upper wind collection structure. |
