Abstract: This paper presents a numerical (CFD) analysis of wind flow above six different roof shapes, namely: flat, domed, gabled, pyramidal, vaulted and wedged roofs, for determining the optimum wind turbine mounting location and the optimum roof shape for mounting wind turbines. It was found that the vaulted roof is the optimum roof shape for roof mounting wind turbines as the integrated wind turbine would yield 56 % more electricity than a freestanding wind turbine in the same location under the same flow conditions. On the other hand, the wedged roof had the least accelerating effect on wind above it.
